Opis:
The main aim of the study was to determine which of the viability and germination capacity of pollen grains estimation methods are optimal and to test if the studied sections and species within the Rosa genus are differentiated in pollen viability andgermination capacity. We analysedandcomparedpollen grains of 14 wild Rosa species using 5 viability tests and13 various liquidandagar media. Viability of pollen grains in the majority of the examinedspecies was greater than their germination capacity. The most viable pollen grains were foundin R. gallica (section Gallicanae), where average of 5 viability tests is 90.69%, andin R. pendulina (section Rosa) – 86.85%. Species from section Caninae have a lower level of viability (from 60.59% in R. rubiginosa to 31.23% in R. inodora). Pollen of species from sections Gallicanae (R. gallica; to 63.4%) and Rosa (R. pendulina; to 47.21%) germinatedmuch better than the pollen of the majority of species from section Caninae (with the exception of R. zalana; to 47.22%). The examinedpollen grains germinatedmost numerously on agar medium with 1.5% agar+15% sucrose+50 ppm boric acidandliquidmed ium with 15% sucrose+ 50 ppm boric acid. Following deep-freeze storage (–25°C) for six months, the pollen grains of nine selected species (with the exception of R. rubiginosa) showed viability higher or similar to that before storage.

Opis:
Fresh and stored beechnuts collected in 1992, 1995, 1998, 1999 and 2000 were tested for viability and in 1998, 1999 and 2000 also for germination. Germination parameters such as peakvalue, mean weekly germination (modified mean daily germination), germination capacity, and germination value (Czabator 1962) were calculated from the germination test data and these indicators were also used for comparing beechnut quality. The highest viability for pre-stored beechnuts occurred in 1998 (80%) and this increased by 4% when these seedlots were stored for 1.5 years. Viability of fresh beechnuts collected in 1992, 1995 and 1999 was 64, 73 and 77%, respectively. Viability of 1995-collected beechnuts decreased after 3 years storage. Germination of fresh seeds was only done for the 1998, 1999 and 2000 collections where the best germination occurred for the 1998 collection. Germination of beechnuts collected in 1992 and 1995 was significantly reduced after 3 and 6 years of storage, respectively, while beechnuts collected in 1998 and stored for 1.5 years germinated about 15% better than fresh seeds of the 1999 crop. The peakvalue, mean weekly germination and the time required for viable seeds to reach 80% germination showed that the 1998 crop had the highest, overall quality. Eighty percent of the viable seeds collected in 1998 germinated in 9-10 weeks while fresh beechnuts from 1999 needed nearly 13 weeks to germinate, as did beechnuts collected in 1992 and stored for 7 years. Besides the germination capacity the germination value seems to be the very good indicator for determining the quality of stored beechnuts.

Opis:
The observed juniper decline, lack of natural regeneration, and disappearance of numerous populations of the common juniper in Poland, were the major reasons for initiation of research on its sexual propagation and seedling production. This study shows that seed dormancy in this species is broken by warm-cold stratification at 15°C/3°C, for 14+12 weeks, respectively. Seed drying for 72 h at room temperature in the middle of the warm phase (i.e. after 4–8 weeks of stratification at 15°C) and the following cold stratification at 3°C, cause a significant increase in seed germination capacity at cyclically alternating temperatures of 3~15°C, and in seedling emergence in growing trays (67 cells each) in a greenhouse. However, seedling emergence was over 2-fold to 4-fold lower in an open nursery than in the greenhouse. After sowing in the nursery, secondary dormancy was probably induced, because some seeds germinated in the following year. Some very young, 2-year-old seedlings started to produce male or rarely female cones. This study also showed that soil conditions of mother plants can influence the pattern of seed germination and seed ling emergence.

Opis:
In contrast to earlier reports, in this study Seabuckthorn seeds collected from ripe fruits proved to be non-dormant. Most of them germinated quickly at high temperatures (e.g. cyclically alternating temperatures of 20~30°C daily for 16 and 8 hours, respectively). At lower temperatures (3~20°C), seeds did not germinate or germinatedslowly, but stratification at 3°C for 4–6 weeks increasedtheir germination rate to 90–100% within 2–3 weeks. Seedling emergence in the open nursery proved to be risky, even after 6–8 weeks of seed stratification, so spring sowing in the greenhouse (or plastic tunnel) is recommended.

Opis:
Effects of several stratification variants on seed dormancy breaking were compared in Crataegus submollis Sarg. (hairy cockspur-thorn or Quebec hawthorn). Ripe seeds were collected (in October), cleaned, and dried to a moisture content of 7–12%. Seed dormancy in this species was broken most effectively by warm-cold stratification of nutlets, in a substrate or without any substrate, at 15~25°/3°C or 20~30°/3°C, i.e. with a cyclically alternating warm stage (16+8 hrs or 24+24 hrs/cycle) lasting 16–20 weeks, followed the cold stage lasting ca. 20 weeks, i.e. till the appearance of the first germinating seeds. After stratification, emergence rate is equally high (ca 50%) at cyclically alternating temperatures of 3~15°C and 3~20°C (16+8 hrs). Chemical scarification of nutlets in 96% sulphuric acid for 3 hrs, followed by warm-cold stratification at 20~30°/3°C, with a short, 4-week warm stage, also ensures a high emergence rate (58%). Seed desiccation (in nutlets) slowly to a moisture content of 10–12%, after stratification in a substrate or without any substrate as well as after scarification, results in a reduced emergence rate, especially if seeds are dried to the lower moisture content. Seed storage (in nutlets after drying to a moisture content of 10%) for 10 years at –3°C, does not decrease the emergence rate (93%) after stratification at 20~30°/3°C in a substrate, with a cyclically alternating warm stage (24+24 h) lasting 16 weeks.

Opis:
The most advantageous time for collecting fruits of the common hawthorn (Crataegus monogyna Jacq.) falls on October, when they are fully ripe. The stones extracted from the fruits must be dried at room temperature to the moisture content of about 10%. The dormancy of the common hawthorn seeds can be overcome by their stratification in a moist medium in one of the three thermal regimes: - 25°/3°C (16 weeks at 25°C followed by 15-18 weeks at 3°C, i.e. to the time when the first seedlings start to appear) - 20~30°/3°C (16 weeks at 20~30°C (16+8 hrs/day) followed by 15-18 weeks at 3°C, i.e. to the time when first seedlings start to appear) - 20~30°/3°C (16 weeks at 20~30°C (24+24 hrs) followed by 15-18 weeks at 3°C, i.e. to the time when first seedlings start to appear) Having been stratified, the seeds germinate vigorously (in 3-5 weeks) and at a high percentage at temperatures of 3~10°, 3~15°, 3~20° and 3~25°C, (16+8 hrs/day) and the seedlings emerge at 3~20°C (16+8 hrs/day) in 4-6 weeks. Storage for one year at -3°C in the case of the seeds dried after harvest to the moisture content of 10% does not reduce their germination capacity. Stones scarification in concentrated sulphuric acid for 120 minutes followed by stratification at 3°C has an adverse effect on seed emergence at the temperature 3~20°C (16+8 hrs/day). It is recommended that stratified seeds should be sown into the still cool soil at the end of March or the beginning of April, as the increased temperature induces the secondary dormancy in seeds.

Opis:
Germination and viability of stored European beech (Fagus sylvatica) seeds can vary depending upon the time when the tests are done during seed storage. To determine the possible sources of such variation the germination (GERM), germination rate expressed as mean germination time (MGT) and viability (VIAB) of six beechnut lots (three lots from two crop years) were determined monthly for one year using controlled laboratory conditions and standard tests. Higher GERM of some lots occurred when tests for stored seeds were carried out in spring and early autumn while other lots germinated better during summer tests. Similarly, different germination speed (dormancy release) and VIAB were observed in different months for different lots. However, no consistent seasonal fluctuation in GERM, MGT or VIAB of the beechnuts was observed in the tests. The reason for this fluctuation seems to be initial quality (germination and dormancy) of beechnut lots rather than any endogenous factors

Opis:
The investigation of dormancy release in Aesculus hippocastanum seeds was aimed at estimating the proportion of coat-imposed to embryo dormancy, and studying the growth initiation providing embryo dormancy release. During winter, horse chestnut seeds exhibited 16–17 week-lasting deep dormancy, which predominantly was determined by coat-imposed dormancy. Embryo dormancy lasted for 11–12 weeks of wet cold stratification. Embryo dormancy was weak, even the embryo axes excised from deeply dormant seeds were capable of extending to the size exceeding the axis length in intact seeds at radicle protrusion. Embryo dormancy release manifested itself in gradually increasing growth capacity of both embryo axes and cotyledonary petioles. The growth initiation in horse chestnut seeds occurs only by cell elongation. During growth initiation, a more rapid fresh weight gain was observed in comparison with length increment, thus indicating that accumulation of osmotically active substances and active water uptake by embryo axis cells were ahead of their increasing longitudinal cell wall extensibility. Cell wall loosening appeared to be directly related to embryo dormancy release. The hormonal regulation of embryo dormancy release in horse chestnut seeds is discussed.

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.

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.

Wildolive seeds (Olea europaea L. var. sylvestris), calledoleaster do not germinate when placedunder favourable conditions. In a series of experiments the effects of the harvest date, the endosperm, the tegument, andthe coldtreatment were evaluatedon germination of seeds andembryos. The germination percentage of embryos and seeds harvested at different harvest dates increased during October month, these percentages decreased during November month, whereas no seeds and embryos harvested on the middle of December germinated. Embryo germinability was always higher than seed germinability, and this may be due to an inhibiting effect of the teguments and the endosperm on seed germination. Such dormancy, which gradually increased during maturation, could reside mainly in the endosperm and partly within the embryo. The cold treatment at 4°C for four to thirteen days increased seed and embryo germinability, whereas lengthening time at this temperature showeda negative effect on seedgermination. The germination of seeds andembryos from six wildolive trees was also examinedby recording the germination percentage andminimum imbibition time (Tmi).

Opis:
Serbian spruce (Picea omorika /Panc./Purkyne) is a Balkan endemic and Tertiary relict, therefore it has an exceptional significance from the historical-geographical aspect as well as from the aspect of tree improvement and biodiversity conservation. Pollen was collected from 24 trees in two consecutive years and analyzed once a month. Germination of fresh pollen and pollen stored under different temperatures (room temperature: 23 ±1°C, +4°C, –15°C and –20°C) by in vitro method on a medium with 10% sucrose was analyzed. Fresh pollen germination was 53.63% and 68.06% for pollen collected in first and second year, respectively. After one year of storage at –20°C pollen germination was 22.36% and 60.72%, respectively. The differences between pollen collection years, temperature treatments, storage periods and individuals were statistically significant. Since pollen germination rates of individual trees between the first and the second year showed weak positive correlation, one could conclude that germination of fresh pollen grains is under the certain influence of environmental conditions. It is determined strong positive correlations between fresh and stored pollen at –20°C from both years of pollen collection.

The present study was carried out to determine the effect of temperature on the seed germination of Fraxinus ornus subsp. cilicica, an endemic taxa on Taurus Mountains in Southern Turkey. Seeds from the three provenances were collected and prechilled for 16 weeks before the germination tests. Germination tests were conducted at constant temperatures (5, 15, 20, 25°C) and at alternating temperatures (5~15, 5~20, 5~25, 15~25°C). Temperature treatments were effective on germination percentage and mean germination time. The highest and the lowest germinability were obtained at the 5–15°C (73.3%) alternating and 25°C (9.8%) constant temperatures, respectively. Mean germination time greatly differed at various temperature regimes. Germination accelerated with increased constant temperatures while it was relatively similar speed at alternating temperatures used in the tests. Seed sources had also an effect on the final germination percentage.

The effects of stratification and scarification on seed dormancy breaking were compared in scarlet hawthorn (Crataegus pedicellata Sarg. = C. coccinea L). Ripe fruits were collected (in October) and the extracted nutlets were cleaned, and dried to a moisture content of 9–12%. Seed dormancy in this species was broken most effectively by warm-followed-by-cold stratification of nutlets, in a substrate or without any substrate, as well as at 15~25° or 20~30°C, i.e. with a cyclically alternating warm stage (16+8 hrs or 24+24 hrs/cycle) lasting 16–20 weeks, followed by the cold stage at 3°C lasting ca. 20 weeks, i.e. till the appearance of the first germinating seeds. After stratification, emergence rate is equally high (ca 76%) at cyclically alternating temperatures of 3~15°C or 3~20°C (16+8 hrs). Chemical scarification of nutlets in 96% sulphuric acid for 2 hrs, followed by warm-cold stratification at 20~30°/3°C, with a short, 4-weeks warm stage, also ensures a high emergence rate (85–93%). Seed desiccation (in nutlets) slowly to moisture content of 12–14%, after stratification in a substrate or scarification does not reduce the seedling emergence of seeds. Emergence decreased when seeds were desiccated after stratification without any substrate. Results provide new methods of breaking of dormancy and high germination and emergence of hard-coated Crataegus seeds in controlled conditions.

Mountain almond (Amygdalus arabica) is a shrub with naturally distributing in Turkey, Iran, Iraq, Syria, Jordan and Saudi Arabia. A. arabica also known as bitter almond and can reach up to 2.5 m. The natural distribution of mountain almond is generally in the Southeast Region of Turkey. The present study carried out to determine the morphological and physiological characteristics of the seed of mountain almond. The seeds were collected from three different populations of A. arabica in Adıyaman. For different each populations seed weight, height, width, thickness, and 1000-seed weight were measured in the laboratory. Morphological characteristics of A. arabica seeds varied according to their populations. Seed germination tests were conducted at 20 °C, after prechilling for 0, 3, 6, and 9 weeks at 4 °C. Prechilling treatments of 3 weeks were insufficient, but 6 and 9 weeks of prechilling were found to eliminate seed dormancy and led to the highest germination percentage. The average germination percentage after 0, 3, 6, and 9 weeks of prechilling were 3.1%, 49.6%, 80.4%, and 81.1%, respectively. The average mean germination time was approximately between 8 and 10 days.
