Opis:
The ecophysiological regulation of seed dormancy in perennial species and those with a varied life cycle has not been studied in detail yet. That is why an attempt has been made to determine the Cirsium arvense seed water relations during stratification and afterripening at different temperatures and germination at constant or fluctuating temperatures on the basis of the hydrotime model. The obtained results showed that breaking of the primary dormancy of achenes took place only during the first stratification month at moderate temperatures, mainly due to an increase in the average water-stress tolerance in a seed population. The induction of secondary seed dormancy during after-ripening at all temperatures resulted mostly from a substantial loss of the seeds' ability to tolerate water stress. Fluctuating temperatures affected neither seed germination nor the hydrotime model parameters. The analysis of the variations of hydrotime model parameters allows a better understanding of the physiological basis of seed dormancy relief and induction.

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:
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:
Laboratory experiments were made to determine the optimum conditions for dormancy breaking in the midland hawthorn (Crataegus laevigata (Poir.) DC. = C. oxyacantha L.). Its small applelike fruits should be collected when they are fully ripe (in Poland in October). The nutlets extracted from the fruits must be dried at room temperature to the moisture content of 9–13%. The dormancy of midland hawthorn seeds can be overcome by: (1) stratification in a moist medium: 20~30°C/3°C, 16–20 weeks at 20~30°C (16+8 hrs or 24+24 hrs) followed by 16–18 weeks at 3°C, i.e. to the time when first radicles start to appear; or (2) chemical scarification in concentrated sulphuric acid for 2 or 3 hrs, followed by warm stratification at 27.5°C or 20~30°C for 4 weeks and cold stratification at 3°C, lasting 19–21 weeks, i.e. to the time when first radicles start to appear. The stratified seeds germinate vigorously (in 3–5 weeks) and at a high percentage at temperatures of 3~15°C or 3~20°C (16+8 hrs) and all seedlings emerge in such conditions about 4–6 weeks after sowing. Seed germination after stratification or scarification can be stopped by partial desiccation of seeds. Seed desiccation after stratification to the moisture content of 10–13% and sealed storage at –3°C for one year do not reduce seed germination and seedling emergence rates of the previously pretreated seeds. Storage for 20 months at –3°C of seeds dried after harvest to the moisture content of 14% does not reduce their germination and seedling emergence.

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.

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:
Materiał doświadczalny stanowiły 32 linie Triticum durum Desf. i jedna wzorcowa odmiana Triticum aestivum L. Kłosy zebrane w polu moczono w wodzie (15 minut) i umieszczano w komorze wilgotnościowej. Odporność na porastanie oceniano po 3 i 7 dobach. Kłosy suszono w suszarce, a następnie młócono ręcznie oddzielając ziarniaki porośnięte od nie porośniętych. W tym samym czasie oznaczano kiełkowanie nasion na bibule w szalkach Petriego. Ocenę tą powtórzono po 4 i 8 tygodniach. W ostatnim terminie wykonano też kiełkowanie w 10-4 M roztworze kwasu abscysynowego. Wrażliwość na ABA podano w procentach jako iloraz różnicy średnich wartości energii kiełkowania w wodzie i ABA przez wartość dla wody. W warunkach komory wilgotnościowej wzorcowa odmiana pszenicy zwyczajnej wykazała się dużą odpornością na porastanie. Stwierdzono duże zróżnicowanie linii pszenicy twardej pod względem jawnego porastania ziarna (W = 99% po 3 dobach i W = 50,7% po 7 dobach). Najodporniejsze linie porastały na poziomie wzorcowej odmiany T. aestivum L. (w pierwszym terminie 13, a w drugim 1). Dla porastania ziarna otrzymaliśmy u T. durum wysokie wartości współczynników odziedziczalności w szerokim znaczeniu (h2 = 0,93 i 0,92). Oceny jawnego porastania po 3 i 7 dobach nawilżania kłosów były skorelowane z energią kiełkowania (rxy = 0,408 i 0,608) oznaczaną w tym czasie w szalkach Petriego. U większości badanych form pszenicy twardej jawne porastanie ziarna w kłosach było wyraźnie mniejsze od kiełkowania w szalkach. U trzech linii porastanie w kłosach było większe od kiełkowania na bibule. Korelacje pomiędzy porastaniem ziarna w kłosach i współczynnikami wrażliwości na ABA, oznaczanymi po zaniku spoczynku pożniwnego, były w naszych badaniach nie istotne.
The experimental material consisted of 32 lines of Triticum durum Desf. and one standard variety of Triticum aestivum L.. Ears harvested in the field were soaked in water (15 minutes) and placed in moist chamber. The resistance to sprouting was evaluated after 3 and 7 days. The ears were dried in dryer and threshed manually with separation of sprouted grains from those not sprouted. Simultaneously, the germination of grains was measured on a filter paper in Petri dishes. This evaluation was repeated after 4 and 8 weeks. Last time sprouting in 10-4 M solution of abscisic acid was carried out. Grain responsiveness to ABA was given in percentage as the quotient of the result of subtraction of average values of germination energy in water and ABA, and the value in water. Under the moist chamber conditions the standard of common wheat variety showed high resistance to sprouting. The results proved a high variability of durum wheat lines with regard to visible grain sprouting (W = 99% after 3 days and W = 50.7% at the second notice). The most resistant lines of T. durum sprouted on the level of standard T. aestivum variety (at the first time 13 lines, at the second time 1). Heritability coefficients in broad sense estimated for grain sprouting were very high (h2 = 0.93 and 0.92 – respectively for the 3 days and the 7 days results). The estimations of visible sprouting of moistened ears after 3 and 7 days were correlated with germination energy (rxy = 0.408 and 0.608) which were evaluated at the same time in Petri dishes. In majority of the studied lines of durum wheat the visible grain sprouting in ears was distinctly lower than germination ability determined in Petri dishes. In three lines sprouting in ear was higher than germination on a filter paper. The correlation coefficients between grain sprouting in ears and ABA responsiveness coefficients, assessed after post-harvest period, were in our study not significant.
