Opis:
Low temperature stress is one of the limiting factors of seed germination. In order to investigate the effect of lowtemperatures on germination of barley cultivars, identification of traits related to low temperature stress at germinationstage and the effect of calcium chloride on these traits, 44 Iranian and European barley cultivars were evaluatedin a factorial experiment within completely randomized design with 3 replications in the Laboratory of Plant Physiology,Agronomy and Plant Breeding department, Razi University. The first factor was 44 Iranian and European barleycultivars, the second factor included four temperature (0, 5, 10 and 20°C), and the third factor was the use of calciumchloride (10 mM) and its non-use (distilled water). Analysis of variance showed that there was a significant differencebetween cultivars for all traits except root length and seed vigor. Applying calcium chloride treatment ata concentration of 10 mM did not significantly affect the traits under the studied temperatures. Reducing temperaturefrom 20°C to 10°C and 5°C reduced root length, shoot length, coleoptile length, root number, coefficient of velocityof germination, seed vigor and promptness index. The results of correlation analysis showed that there wasa significant positive correlation between promptness index with average velocity of germination, coefficient ofvelocity of germination and seed vigor, germination percentage and root number in all studied temperatures. Therewas little differentiation between Iranian and European cultivars by both cluster and discriminant analysis.

Opis:
The date seeds (DS) biochar produced at 550°C was found to be appropriate for remediation of metal-contaminated water. This was evident in the data, which showed that applying the biochar to Raphanus sp. and Arabidopsis sp. reduced metal stress and toxicity. The LC50 of all tested metals solutions on seed germination was increased significantly (P<0.05) in Raphanus sp. by 10.4, 2.3, 5, 1.8, and 3 folds, respectively, for Cu, Zn, Cd, Pb, and metals combination, and by 5, 3.4, 6, 5.5, and 2.5 folds in Arabidopsis sp. For seedling growth, the DS biochar enhanced the LC50 significantly (P<0.05) of the same metals in Raphanus sp. by 9.6, 9.2, 13.8, 12.1, and 1.6 folds, and in Arabidopsis sp. by 7, 3, 2.3, 2.9, and 2.7 folds, respectively. The LC of all metals was increased by 1.5 to 8 times and 1.5 to 12 times, respectively, for the seed germination and seedling growth of Raphanus sp. and Arabidopsis sp. Both plants were able to grow shoots at higher metal concentrations when the DS biochar was employed, as compared to the case when no DS biochar was utilized. In terms of shoot length, similar results were achieved, with the DS biochar application significantly enhancing shoot length (P<0.05), as compared to the case when no biochar was applied. Despite the fact that Arabidopsis sp. was more sensitive to metals than Raphanus sp., both plants raised their RGR and TI and reduced their phytotoxicity values in all metals following the DS biochar application, and sprouted at higher metal concentrations than before. These findings introduce a successful eco-friendly adsorbent for metal removal from aquatic environments, paving the way for more investigations.

Opis:
The seeds of 3 populations from Satureja bachtiarica were collected from three native vegetation areas (Simirom2, Sharkord and Yazd). The different treatments including: cold stratification, gibberlic acid (50 and 100 ppm) Potassium nitrate (0.2 and 0.4 percent). Physical scarification (sand paper), chemical scarification (Ethylic alcohol %70) and distilled water (control) were used for breaking dormancy of the seed samples. For greenhouse experiment, the seed samples were treated with treatments and then were sown in pots using randomize design with three replications. Emergence percentage, emergence speed, length of root and shoot, seedling length, root/shoot length ratio, vigor index, seedling fresh and dry weight, dry/fresh weight ratio were evaluated during 45 days of experiment. Comparing of population Semirom2 form savory of Bachtiary was higher than other population. It was concluded that effect of gibberlic acid and potassium nitrate was higher than physical scarification and chemical scarification comparing with control.

Opis:
Regions with warm climate are poor in organic matter or have a deficit of soil. The purpose of the work was to select the optimal mix from biodegradable wastes such as cardboard (Cb), natural textiles (Tx) newspaper (Np), colored newspaper (Cp), and office paper (Op) for creating artificial soil by combining these materials with compost and sand. To select the optimum mix, 15 samples were taken (3 from each type of waste in the following proportions: 25%, 50% and 75% ). The optimum mix was analyzed for grass germination rate and root development. Tests were performed in the laboratory with conditions similar to those of regions with warm climate and soil deficiency in a specially designed testing spot (bioterm). The effects of particular mixes on plant germination rate and growth were measured. Out of all mixes, the textile compositions Tx50 and Tx25 supported best the plant propagation. During the whole experimental process, the grass showed various growth tendencies. The best results for grass height were observed for mixes with textiles and colored newspaper. Based on this data and subsequent laboratory research, the best substrate composition was selected. For the whole period of the tests, germination rate in the pot with the mix was higher than the germination rate in the control sample with compost. Considering the experimental conditions of this research, the tested substrates can be used to aid in plant propagation, especially in regions with warm climate and soil deficiencies, and for restoration of damaged land areas.

Opis:
Quercus alnifolia is an endemic species in Cyprus, and it is rated as Vulnerable (VU) in the Red List of Oaks. Although Q. alnifolia has a great ecological importance, there are only few studies about this species. In this work we have studied the natural variability of this species by analyzing acorn dimensions, acorn mass, length of embryo, moisture content of acorns and seed germinability among the seven acorn provenances, collected in Cyprus. We also determined the seeds responses to drying. Germination trials were also carried out, and differences in seed germination among populations were examined. Rate of water loss and its effect on seed germination was also estimated by application of specific desiccation treatments. The results showed that acorn characteristics significantly differed between the populations, following a general trend to reduce their dimensions and mass with the altitude increase. Seed germination was high for all studied populations, and germination behaviour was similar for all populations. Desiccation of acorns below 35% resulted in a great reduction of seed germination capacity.

Opis:
Background. Nanoparticles have been applied worldwide, posing substantial effects on the environment and its living organisms. Plants as sessile organisms are always exposed to considerable fluctuations of nanoparticles concentrations. Here, the effects of different concentrations of bulk and nanosized $Al_2O_3$ on seed germination and seedling growth of Cynara scolymus were investigated in a randomized completely design with four replications. Material and methods. The experimental treatments included four concentrations of bulk $Al_2O_3$ (10, 50, 100 and 500 ppm), four concentrations of nanosized $Al_2O_3$ (10, 50, 100 and 500 ppm), and control without any $Al_2O_3$. Results. The results indicated that among the Cynara scolymus germination indices, only mean germination time and weighted germination index was not affected by treatments. In addition, plumule length, radicle length, seedling fresh and dry weight were affected by bulk and nanosized $Al_2O_3$concentrations, significantly. Radicle length at 50 ppm concentration of nanosized $Al_2O_3$ was higher than those of the untreated control and bulk $Al_2O_3$Al 2O3 at 10, 100 and 500 ppm concentrations. It is concluded that treatment with bulk $Al_2O_3$ treatments have more inhibitory effects on germination indices of Cynara scolymus in comparison to nanosized $Al_2O_3$. Conclusion. Overall, we found through our study that bulk and nano sized $Al_2O_3$ in high concentrations have a negative impact on the seed germination and seedling growth of Cynara scolymus. We saw an overall significant reduction in plumule length, seedling dry biomass, and vigor index of Cynara scolymus seedlings after being exposed to different concentrations of bulk and nano sized $Al_2O_3$, but no significant change in the mean germination time, weighted germination index and radicle length of the seedlings. The two common possibilities are either the bulk and nano sized $Al_2O_3$ will adhere to the roots impeding any uptake of water and nutrients, or that the nanoparticles are up taken and translocated within the plant therefore causing toxicity internally.
Nanocząstki są stosowane na całym świecie, wywierając znaczny wpływ na środowisko i żywe organizmy. Rośliny jako organizmy ukorzenione są zawsze narażone na znaczne wahania stężeń nanocząstek. Zbadano wpływ różnych stężeń $Al_2O_3$ w masie i nanocząsteczkach na kiełkowanie nasion i wzrost siewek Cynara scolymus w całkowicie losowym projekcie z czterema powtórzeniami. Zabiegi doświadczalne obejmowały cztery stężenia $Al_2O_3$ w masie (10, 50, 100 i 500 ppm), cztery stężenia $Al_2O_3$ w postaci nanocząstek (10, 50, 100 i 500 ppm) oraz kontrolę (bez $Al_2O_3$). Wyniki wskazują, że spośród wskaźników kiełkowania Cynara scolymus zabiegi nie miały wpływu na średni czas kiełkowania i ważony wskaźnik kiełkowania. Na długość pędu embrionalnego, długość korzonków, świeżą i suchą masę siewek istotnie wpływały stężenia $Al_2O_3$ w masie i nanoskali. Długość rodnika przy stężeniu 50 ppm $Al_2O_3$ w postaci nanocząstek była wyższa w porównaniu z kontrolą i masowym $Al_2O_3$ przy stężeniach 10, 100 i 500 ppm. Stwierdzono, że traktowanie dużą ilością $Al_2O_3$ ma bardziej hamujący wpływ na wskaźniki kiełkowania Cynara scolymus niż stosowanie $Al_2O_3$ w postaci nanocząstek. W badaniach określono, że Al2O 3 w dużych ilościach i w wysokich stężeniach nanocząsteczek ma negatywny wpływ na kiełkowanie nasion i wzrost siewek Cynara scolymus. Zaobserwowano znaczne zmniejszenie długości pędu embrionalnego, suchej masy sadzonek i wskaźnika wigoru siewek Cynara scolymus po ekspozycji na różne stężenia $Al_2O_3$ w rozmiarze masowym i nano, ale bez znaczących zmian w średnim czasie kiełkowania, ważonym wskaźniku kiełkowania i długości korzonków siewek. Wynika to albo z przywierania $Al_2O_3$ do korzeni w rozmiarze masowym i nanometrowym, utrudniając wchłanianie wody i składników odżywczych, albo nanocząsteczki są pobierane i przemieszczane w obrębie rośliny, powodując w ten sposób toksyczność wewnętrzną.

Interspecific compatibility and self-compatibility in Pyrus communis, P. pyraster and P. salicifolia were evaluated. Degree of compatibility was determined by means of fluorescence microscope. Self-incompatibility evaluated on the basis of the pollen tubes growth showed that two cultivars of P. communis (Bera Hardy and Lukasówka) were self-compatible and the other three cultivars were self-incompatible. All ecotypes of P. pyraster are self-incompatible. In interspecific crosses full inter-incompatibility or unilateral self-incompatibility was observed.
Na podstawie obserwacji łagiewek pyłkowych, wykonanych przy użyciu mikroskopu fluorescencyjnego, oceniono samozgodność oraz samoniezgodność u pięciu odmian sadowniczych gruszy pospolitej Pyrus communis ('Packhams Triumph', 'Bera Hardy', 'Lukasówka', 'Konferencja' i 'General Leclerc'), 5 drzew gruszy dzikiej Pyrus pyraster rosnących w okolicach Poznania oraz jednego drzewa gruszy wierzbo-listnej Pyrus salicifolia. Kwitnące pędy grusz zostały umieszczone w laboratorium i w tych warunkach przeprowadzono zapylanie. Słupki do obserwacji zbierano po 48 godzinach od momentu zapylenia. Obserwacje wzrostu łagiewek pyłkowych wykazały, że dwie odmiany Pyrus communis ('Bera Hardy', 'Lukasówka') były samozgodne a 3 inne były samo niezgodne. Wszystkie ekotypy Pyrus pyraster były samoniezgodne. W międzygatunkowych krzyżowaniach obserwowano pełną lub jednokierunkową niezgodność.

The seed germination percentage was decreased with increased in the concentration/doses when compared to control. The LD50 (Lethal dose) value was determined based upon the seed germination percentage. The 50 percentage of seed germination and reduction was observed in 20KR of gamma rays and 25mM of EMS and it is considered as LD50 value for both the treatments. The decrease in seed germination was more prominent with gamma rays than that of EMS treatments. The seedling parameters of gamma rays and EMS treated seedlings were progressively decreased with increase dose/concentration in all mutagenic treatments when compared to control. The maximum seedling parameters were observed in 05KR of gamma rays and 05mM of EMS. Minimum seedling parameters were observed in 50mM of EMS and 50KR of gamma rays respectively.

Opis:
The fundamental aim of this study was to investigate the growth responses of selected Jordanian cultivated barley (Hordeum vulgare L.) genotypes to the salinity stress. Twenty-six landraces and two recent cultivars were subjected to four levels of salinity (0, 50, 100 and 200 mM NaCl). The salt stress was found to influence the majority of germination ability such as germination % which ranged from about 80% to 100% (One-way ANOVA; p ≤ 0.05). Moreover, germination was statistically affected in correspondence to exposure time to salinity and in relation to genotypic composition of studied barley (two-row vs. six-row accessions) (Two-Way ANOVA; p ≤ 0.05). Early seedling growth traits were also found to decline with increasing salinity stress. Moreover, according to the growth parameters genotypes, M’ 1595, M’ 1593, Ir 1558, Ir 1631, Ir 1639, Mf 1545, and Mf 1548 were found to have better performance than others. On the other hand, the genotypes M’ 1593, M’ 1594, M’ 1595, Ir 1558, Ra 1552, Ra 1611, Mf 1616, Mf 1617, and Ma 1592 were most affected genotypes by salinity. The results of this study lead to the conclusion that the response to the salinity stress is complex, yet the comprehensive results found in this study provide a foundation for deeper exploration of diversity as well as the gene–trait relationships and their utilization in future barley improvement.

Opis:
Composting is commonly used for waste management and the evaluation of its quality is important for successful application. Seed germination test is commonly adopted due to its capacity to examine the toxicity level of compost. The seed test is usually evaluated on the final product and the results can vary with the different methods and the type of seed utilized. In this study, the evolution of seed germination tests during the composting process of municipal waste (MSW) mixed with poultry manure (PM) of two species tomato and sugar beet was examined. The impact of compost water extracts on seed germination and plant primary root growth for each sampling was reported. The chemical parametrs were evaluated on the final product. Results show that mixture C1 with a higher amount of municipal waste gave less compost yield than mixture C2. After 35 days of composting, the compost was phytotoxic for tomato and sugar beet seeds. The seeds of the two cultures reacted differently to the same compost. The compost could stimulate sugar beet germination at days 110, 140, 180, 212 and 252. Seed germination of sugar beet was increased and delayed by one day by the compost stabilized and mature as compared with the control.

Opis:
The effect of six SiO2 nanosized concentrations (0, 5, 20, 40, 60 and 80 mg L-1) and three seed prechilling treatments (control, seed prechilling before nano SiO2 treatments, treatments of seed with nano SiO2 before prechilling) on germination and seedling growth of tall wheatgrass (Agropyron elongatum L.) were studied. Results indicated that application of SiO2 nanoparticles significantly increased seed germination of tall wheatgrass from 58 percent in control group to 86.3 and 85.7 percent in 40 and 60 mg L-1, respectively. Applying SiO2 nanoparticles increased dry weight of shoot, root and seedling of tall wheatgrass. Increasing concentration of nanoparticle from 0 up to 40 mg L-1 increased seedling weight around 49 percent compared to the control, nevertheless decreased under 60 and 80 mg L-1 treatments. In conclusion, seed prechilling in combination with SiO2 nanoparticles largely broke the seed dormancy for A. elongatum.
