Opis:
Two experiments were conducted to evaluate ageing-induced genetic changes and to establish physiological thresholds for loss of genetic integrity during ageing or storage of rice seeds. In the first experiment, seeds of 10 varieties of rice were subjected to artificial ageing in chambers conditioned to 55°C and 72±2% RH for 72 hours. In the second experiment, seeds of 4 varieties of rice stored in the NACGRAB gene bank, Nigeria in 2011 at 5± 4°C were compared with seeds of the same accessions freshly harvested in 2013. Data were collected on seed germination and seedling length to estimate the seed vigour index. Genetic changes during the ageing were evaluated by SSR markers using a Direct™ PCR kit. Genetic distance indices were computed using PAST™ software and percentage genetic integrity was estimated from the genetic distance matrices. At 72 hours of artificial ageing, seed germination percentage declined to 54.2% and vigour index 0.8 coinciding with the lowest estimate of genetic integrity of 99.5%. The decline in percentage genetic integrity during the artificial ageing indicated a systematic ageing-induced genetic alteration. SSR primer RM178 revealed variations that suggest losses of alleles in the course of ageing for 2 accessions at between 24 hours in WITA4 and 48 to 51 hours in CG14. In the gene bank storage trial, germination of seeds after one and two years of storage was above 80% and there were no significant differences among the accessions. SSR profiles for all the accessions were also similar. The result partly corroborates the artificial ageing data. This implies that seed viability benchmark of 54% is recommended for regeneration of stored rice seeds in order to maintain optimum genetic integrity during storage.

Opis:
The aim of the research was to determine the occurrence of primary dormancy in seeds of 18 tomato genotypes (Solanum lycopersicum L.) – 16 cultivars and two local genotypes – regenerated for the active collection of the National Institute for Horticultural Research. The plants were grown in the field in accordance with the adopted methodology of seed reproduction in the collection of genetic resources of vegetable plants. Tomato fruits were harvested twice a week from July 18 to September 26, 2019. Immediately after harvest, the seeds were extracted from the fruit, cleaned and dried according to FAO standards for gene banks. The seeds prepared in this way were stored for a period of sixty weeks at a temperature of 4±2°C in airtight containers with the addition of silica gel. During this period, after twenty, forty and sixty weeks of storage, their germination was tested. The studied tomato genotypes differed significantly in terms of depth of primary dormancy and rate of releasing from dormancy. Two of the tested cultivars – ‘Parteno’ and ‘Reper’, were characterized by seed dormancy at the level of 44.5% and 35.5%, two genotypes – ‘Amber’ and the local genotype POLPOB17-27 were characterized by dormancy levels of 15% and 18%. Seeds of two of the genotypes studied that did not show primary dormancy twenty weeks after harvest – ‘Zealand’ and the local genotype POLPOB17-28 – after storage for sixty weeks showed a reduced germination rate and a longer mean germination time. It is concluded that the optimum time for testing the germination of tomato seeds stored after harvest at 4 °C is forty weeks after harvest. The level of primary dormancy of the seeds is then the lowest, but the induction of secondary dormancy does not occur yet. When testing the seed germination in an earlier period, dormancy breaking procedures should be considered to obtain correct results.

Opis:
Willows produce fast germinating and short-lived seeds, difficult to store in the long-term under controlled conditions. The aim of this study was to examine the feasibility of storage of three Salix spp. at controlled temperatures (3°, −10°, −196 °C). We also analyzed the effect of spermidine (Spd) as an antioxidant factor in desiccated seeds. Collected seeds were either desiccated or hydrated to obtain 10 levels of moisture content (between app. 4% and 2%) and subjected to storage at temperatures 3°, −10°, or −196 °C (liquid nitrogen; LN). After two months, seeds were germinated on the light at 20 °C. Seeds desiccated below a safe range of moisture content were further tested and germinated on filter paper with additions of 0.25 mM Spd solution. After 7 days seedlings were examined for hydrogen peroxide content (H2O2) and total antioxidant capacity (TAC). Fresh seeds of three Salix species: Persian willow (S. aegyptiaca L.), heartleaf willow (S. cordata Michx.) and crack willow (S. ×fragilis L.) were successfully stored at temperature −10° and −196 °C for two months. After cryopreservation seed of S. aegyptiaca, S. cordata, and S. ×fragilis germinated without viability loss in moisture content ranging from 4.4–15.9%, 6.4–18.5%, and 7.1–11.5% respectively. The addition of Spd during germination of desiccated seed did not affect germination capacity. However, seedlings of S. aegyptiaca had lower hydrogen peroxide content in comparison with control (germination on water). Seedlings of S. cordata showed an increase in hydrogen peroxide content in control after storing in LN. In seedlings of Crack willow Spd increased hydrogen peroxide content. Seeds of tested species differ in response to storage conditions. Salix seeds can be stored successfully for two months at −10° or −196 °C without losing viability in the safe range of moisture content. Storing at 3 °C can be used for storage in the narrower range of seeds’ moisture content, however, seedlings stored at this temperature produce a higher level of reactive oxygen species. Germinating seeds in Spd did not increase their germination, however in S. aegyptiaca and S. cordata decreased hydrogen peroxide content.

Opis:
Vicia hirsuta (L.) Gray S.F. (tiny vetch) is a common and persistent segetal weed. Tiny vetch seeds and pods reach different stages of maturity during the crop harvest season. Some seeds that mature before cereal harvest are shed in the field and deposited in the soil seed bank, while others become incorporated into seed material. The objective of this study was to describe selected aspects of tiny vetch seed ecology: to determine the rate of individual reproduction of vetch plants growing in winter and spring grain crops and to evaluate the germination of seeds at different stages of maturity, subject to storage conditions. The seeds and pods of V. hirsuta were sorted according to their development stages at harvest and divided into two groups. The first group was stored under laboratory conditions for two months. In the autumn of the same year, the seeds were subjected to germination tests. The remaining seeds were stored in a storeroom, and were planted in soil in the spring. The germination rate was evaluated after 8 months of storage. Potential productivity (developed pods and flowers, fruit buds) was higher in plants fruiting in winter wheat than in spring barley. Vetch plants produced around 17-26% more pods (including cracked, mature, greenish-brown and green pods) and around 25% less buds in winter wheat than in spring barley. Immature seeds were characterized by the highest germination capacity. Following storage under laboratory conditions and stratification in soil, mature seeds germinated at a rate of several percent. After storage in a storeroom, seeds at all three development stages broke dormancy at a rate of 72- 75%. The high germination power of tiny vetch seeds stored in a storeroom indicates that this plant can be classified as an obligatory speirochoric weed species.

Opis:
Irregular seed crop in Betula pendula (Silver Birch) is a reason to create seed reserves, ensuring nursery production in years of crop failure. This study investigated the effects of seed moisture content and storage temperature on germinability and seedling emergence in container cultivation. Mature catkins were collected separately from 3 trees. The mixture of winged nuts and scales was dried to 3 levels of moisture content and stored at 3°C, –3°C and –10°C. After storage for 3, 5 and 6 years, the seeds were separated from scales and next dewinged and sorted in acetone into empty and filled seeds. Cleaned nuts were germinated in the Jacobsen germinator. Besides, to assess seedling emergence, seeds were sown on the surface of peat mixed with perlite, in multi-cell trays under a plastic tunnel. Significant differences in germinability were detected depending on the mother tree, seed moisture content and storage time. The viability of seeds stored at –10°C remained unchanged for 6 years regardless of moisture content (ca. 8–12%). Seeds stored at higher temperatures lost their germinability faster. An unexplained increase in seedling emergence was observed after extended seed storage at –10°C, in contrast to a gradual decrease in seedling emergence after extended storage at –3°C.

Opis:
Evaluation of the genetic diversity present within species is essential for conservation, management and utilization of the genetic resources. The objective of this study was to evaluate genetic variability of 70 com- mon bean genotypes for seed storage proteins, grain morphological characteristics and agronomic traits. Two methods of extracting soluble seed proteins in salt were used. Positive correlations were observed among both seed morphological characters and developmental charac- ters while yield components showed negative correlations with each other. Factor analysis for agronomic and grain  morphological  traits  resulted  in three factors  were named yield  components,   seed morphology  and phenology, respectively. Most genotypes had lower or medium scores for yield components and phenology factors. Considerable diversity was observed for seed morphology factor among the common bean genotypes. Nei’s diversity coefficient (He = 0.4), effective number of alleles (Ae  = 1.69) and number of polymorphic loci (N = 17) indicated larger variation in the extraction method of soluble proteins in low salt (0.2 M NaCl) than high salt (1 M NaCl) condition. Considering that the centers of diversity for common  bean are different in seed size, the result of GST statistics showed that bands with relative mobility of 30, 32, 38 and 40 differen- tiated two weight groups more than other bands. Furthermore, significant differences were observed between these bands for number of pods per plant and number of seeds per plant.

Mycelial growth of the pathogenic fungus Ciboria batschiana (Zopf) Buchwald was examined at nine temperature levels between -3°C and +35°C using pure cultures of the fungus from eleven different provenances located in Germany, Poland, the Czech Republic and Slovenia. The fungus was isolated mainly from cotyledons of acorns of the oak species Quercus robur L. and Quercus petraea (Matt.) Liebl. Even at -3°C the mycelium of the fungus grew well. There were significant differences between the provenances in respect to growth rate and temperature tolerance, especially at low temperatures.

This study was aimed to improve the understanding of germination ecology and to explain the invasive character of the common buckthorn (Rhamnus catharticus) in North America. Its fully mature seeds are characterized by a lack of dormancy. In laboratory conditions, favourable thermal conditions were identified for seed storage, germination and seedling emergence. At the cyclically alternating temperature of 20~30°C (16+8 h daily), seeds of this species showed a high germination rate within few weeks. Two other thermal variants, 3~15°C and 3~20°C (16+8 h daily), were much less effective for seed germination. However, cold stratification (at 3°C) in a moist mixture of peat and sand, lasting 4–8 weeks, caused a remarkable increase in germination rate also at 3~15°C. Seeds extracted from ripe fruits and dried (to a moisture content of about 10%) showed high germination and emergence rates after storage for 3.5 years at –3°C.

Opis:
The Sauerland region of southern Westphalia has the most economic stands of Norway spruce in the state of Northrhine-Westphalia (Germany). As shown by historical research and genetic analysis, the seeds for these stands were imported from Thuringia around the year 1880. Therefore, the two states are collaborating closely to secure the genetic variety of the spruce and develop new sources of seed supply. The survival of the Hochsauerland Norway spruce is now under threat: these stands have already been harvested or are due for harvesting shortly, in addition, many of the older stands were destroyed by the gale "Kyrill" in 2007, and only a few stands have remained. Since its foundation, the Forest Gene Bank of Northrhine-Westphalia has taken the following measures to preserve the gene pool of the Hochsauerland spruce and conserve it in the long term: storage of seed from 100 representative trees in all the most valuable stands of spruce (since 1985); establishment of seed orchards; and establishment of replacement stands. Thanks to those measures, the genetic information of the Norway spruce stands of Thuringian origin has been secured, and substantial stocks of seed are available for reforestation.

Opis:
Black alder, a major forest tree species in Europe, thrives in moist soils. During the seeds extraction (nutlets) from the cones, the heaviest seeds were observed to fall out first. Seed weight was not correlated to the ability of germination; no significant differences were observed between the heaviest and the lightest seeds. Seeds with a fresh mass moisture content of 8−9% after storage in –3°C retained their high germinability for six winters. However, seedling emergence decreased gradually when tested in cell trays in an unheated greenhouse. Along with the decline of seedling emergence, the participation of high seedlings (≥25 cm) decreased and participation of small seedlings increased simultaneously. These results question whether the practice of storing seeds in –3°C for long time is the best method of germplasm preservation.

Opis:
Successful crop production depends initially on the availability of high-quality seed. Seed viability and vigour of four kenaf varieties during storage were investigated. Seeds of each variety were packed inside thick polythene bags and kept in Seed Stores under ambient conditions in two storage locations (Federal University of Agriculture, Abeokuta (FUNAAB) (29.8°C, 59.10 RH%) and Institute of Agricultural Research and Train- ing, Ibadan (27.5°C, 64.68 RH%) for 240 days (8 months).  Seeds were sampled during storage at 0, 60, 120, 180 and 240 days and tested for seed viability and seedling vigour index. Data collected on seed viability and seedling vigour were analyzed using ANOVA, mean separation using Duncan Multiple Range Test at 5% probability level and PROBIT analysis. The results showed differential responses in the two quality traits due to differences in storage location and varieties. Ibadan storage location provided more favourable conditions for higher seed quality compared to Abeokuta location while Ifeken 400 and Tianung had the best storage potential. The study showed that under ambient humid tropical conditions, storage period should not exceed 180 days (6 months) in order to maintain higher physiological quality with little or no cost. The PROBIT result revealed that the highest seed shelf life (longevity) of kenaf seeds of 8 to 9 months was derived for seeds of Ifeken 400 and Tianung stored in Ibadan and Abeokuta. The shortest shelf life of 6 months was esti- mated for Ifeken 100 stored in both locations.

The studies showed that barley seeds were infected before storage by numerous fungi as well as the saprophytes: Alternaria alternata, Acremonium spp., Acremoniella atra and the pathogens: Bipolaris sorokiniana and ten Fusarium species. The analysis after storage showed that the frequency of fungal infection had changed. The occurrence of some fungi was significantly affected by the period of storage...

The experimental period was December, 2015 to June, 2016. Seed collection was done at the Bobiri Forest Reserve. The seed storage experiment was set up using 3 x 6 factorial arrangements in Completely Randomized Design with three replications. Six packaging materials (jute, nylon, paper, ziplock bag, airtight bottle and no packaging) and three storage periods (no storage, three months storage and six months storage) were used. Germination percentage, seed vigour, 1000 seed weight, moisture content, carbohydrate, protein and oil contents were assessed before storage, three months and six months after storage. P. elata seeds with initial moisture content of 7.5% and packaged in airtight bottle and ziplock bags maintained their moisture contents even as storage periods increased. The initial amounts of seed carbohydrates (1.9%), proteins (37.4%) and oil (31.3%) were maintained in the airtight packaging materials (bottle and ziplock bag) thereby improving seed storability. The seed viability equation predicted that P. elata seeds could be stored for 243 years after six months of storage. Seed viability dropped to 164 days after the accelerated aging test was performed on the six-months old stored seeds. The study concluded that the seeds of this important endangered tree can be stored in airtight containers before the next planting season without any loss in seed quality.

Opis:
Somatic seeds of Plantago asiatica L. were produced for the first time. Shoot-tips isolated from in vitro obtained 4-week shoots were encapsulated using sodium alginate and calcium chloride. Capsules with or without sucrose and with and without cytokinin - indole-3-butyric acid (IBA) were used. Sucrose presence in capsules very distinctly influences somatic seeds of Plantago asiatica germination and their conversion into plants. However, addition of IBA to capsules has not clear influence on the ability of plant regrowth. Plantlets transplanted to soil grew to phenotypically normal plants.

Opis:
Seed vigour, viability, the contents of soluble carbohydrates, total protein, albumins, and globulins, as well as seed coat structure, were analysed in yellow lupin (Lupinus luteus L.) cv. Iryd seeds stored for 20 years at -14oC, 0oC or at room temperature (approx. +20oC). Seed storage at room temperature reduced viability (to 2%) and increased seed leachate electroconductivity. Determinations of total proteins showed that protein content was significantly reduced in seeds stored at +20oC compared to the other storage regimens. Raffinose family oligosaccharides were the main soluble carbohydrates in seeds stored at 0oC and -14oC, whereas sucrose dominated in seeds stored at room temperature. Scanning electron microscopy (SEM) of seed surface and seed coat sections revealed appearance of an amorphic layer on the surface of seeds stored at room temperature (not observed in other seeds) and distinct shrinking of macrosclereid layer in seeds stored at -14oC. Macrosclereids layer in all seeds was 100 um thick and accounted for 60% of seed coat thickness. The obtained results suggest that for long term storage of lupin seeds at 0oC is the most advisable temperature if both costs of storage and seed storability are considered.

Opis:
Shoot tips excised from shoot culture of Salvia officinalis were encapsulated in 2% or 3% (w/v) sodium alginate and exposed to 50 mM calcium chloride for complexation. Immediately or after 6, 12 or 24 weeks of storage at 4°C, the synthetic seeds were cultured for 6 weeks on half-strength MS medium supplemented with indole-3- acetic acid (IAA) (0.1 mg/l) and solidified with 0.7% agar. The frequency of shoot and root emergence from encapsulated shoot tips was affected by the concentrations of sodium alginate and additives in the gel matrix (sucrose, gibberellic acid, MS nutrient medium) as well as duration of storage. The frequency of shoot and root induction of non-stored synthetic seeds was highest with shoot tips encapsulated with 2% sodium alginate containing 1.5% sucrose and 0.5 mg/l gibberellic acid (GA3). Shoot tips maintained their viability and ability to develop shoots even after 24 weeks of storage when they were encapsulated in 3% alginate with 1/3 MS medium, sucrose (1.5%) and GA3 (0.25 mg/l). Root formation tended to decrease with storage time. Overall, 90% of the plantlets derived from stored and non-stored synthetic seeds survived in the greenhouse and grew to phenotypically normal plants. This procedure can enable the use of synthetic seed technology for germplasm conservation of S. officinalis, a plant species of high medical and commercial value.

Opis:
An investigation on Some Engineering Properties and natural durability of Avocado (Persea americana Mill.) pulp and seed were carried out in different locations. Avocado fruit is a tropical fruit and is one of the most productive plants per unit of cultivated area. Avocado stands out for its high nourishing value and it is usefulness to growth and development. It has also been the subject of intense and varied use in the past not only for its importance in food but also for medicinal needs. From the investigation carried out on mechanical properties, avocado seed will attain a value of 2352.200N force at peak and any value higher than this; will cause it to break when determining the effect of moisture content on avocado seed along longitudinal loading. In the same vein, avocado seed will attain a value of 1497.000N force at peak and any value higher than this; will cause it to break when determining the effect of moisture content on avocado seed along axial loading. The thermal properties investigated were thermal conductivity, thermal diffusivity, ash, specific heat and calorific value. This research work and results obtained will enable engineer in designing machines that can be used for processing, handling and storage of avocado pulp and seed.

Opis:
The samples of stored seeds of pea (Pisum sativum L.) were collected from 30 farmer markets. The mycobiota analysis showed presence of 15 fungal species and one species of insect Callosobruchus chinensis. The fungi such as Aspergillus flavus, A. niger, A. ochraceous, A. terreus were found to be dominant based on percent frequency of each in blotter method in unsterilized and sterilized seeds 18.9–7.9, 15.0–3.9, 12.2–3.7, 10.1–1.7, respectively, and in agar plate technique 17.9–8.3, 15.1–9.5, 12.8–5, 7.9.7–6.7, respectively. These species showed reduction in terms of weight loss, germination and protein content in pathogenicity testing. Essential oil extracted by hydrodistillation from fruits of Cuminum cyminum L. was evaluated against the most common occurring funi such as A. flavus and A. niger as well as the insect species C. chinensis and the oil exhibited high toxicity. The oil killed the tested fungi and showed thermostable nature at its minimum inhibitory concentration (MIC) of 400 ppm. The oil safely preserved pea seeds up to 120 days at 0.50 (1,000 ppm) and 0.76 ml (1,500 ppm) in polyethylene and jute bags of 500 ml capacity containing 400 g seeds separately. There were no changes in organoleptic appereance of food seeds during storage. The oil has beneficial effect on number of visible nodule formation and shoot and root dry biomass of 15-day-old plants in comparison to control sets. The cumin oil was analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS).

Opis:
Celem badań było wykazanie różnic wartości siewnej wybranych gatunków zbóż w zależności od zastosowanych zapraw biologicznych. Oceniano zdolność kiełkowania oraz wigor ziarna zaprawionego zaprawami biologicznymi Bioczos BR i Biochikol 020 PC po jednym, dwóch, trzech i sześciu miesiącach jego przechowywania. Porównywane w doświadczeniu gatunki zbóż różniły się w reakcji na stosowane zaprawy. Przechowywanie zaprawionego biologicznymi zaprawami ziarna u prawie wszystkich badanych gatunków obniżało zarówno zdolność kiełkowania, wartość testu wzrostu siewki jak i testu szybkości wzrostu siewki.
The target of the experiment was to determine the sowing value of some cereals grain species depending on some biological seed dressing. Germination capacity and vigor of dressed seeds with Bioczos BR, Biochikol 020 PC after one, two, three and six months of storage were estimated. Cereals' species were differed by reaction to seed dressing. Storage of dressed seeds caused decrease of germination capacity and vigour.
