Seeds of the plant Eucommia ulmoides Oliver, have prominent dormant characteristics. In present study, seed dormancy and germination E. were investigated by treating them with exogenous GA3 different water temperatures. The results revealed that warm soaking treatments beneficial to breaking seeds. rate seeds treated 50℃ was 84.67%. comparison, 300 mg·L-1 had only a 45%. This low resulted proba...

The stems and leaves of the Dolichos biflorus plant contain a lectin that cross-reacts with antiserum against the seed lectin. This cross-reactive material (CRM) was followed during early seedling growth, stem elongation, and seed development using a specific radioimmunoassay.No CRM was detected in developing seeds, but very low levels were found in dormant and imbibed seeds. As germination pro...

Abstract: Analyses of germination seeds under artificial stress conditions are tools for a better understanding the survival and adaptation capacity species natural conditions. Therefore, aim this study was to evaluate effect priming on seed germination, breaking dormancy, length Urochloa brizantha seedlings water restriction salt A completely randomized experimental design used with four repli...

Seed processing and dormancy break treatments are recommended for rendering seeds restoration-ready. Conversely, fruit structures seed coats may protect from environmental harm in the field. We evaluated effects of (by either keeping or extracting seeds) and/or scarification (of physically dormant on seedling emergence establishment 10 legume tree species tropical forests savannas Central Brazi...

Seed banks are common characteristics to many plant species, which allow storage of genetic diversity in the soil as dormant seeds for various periods of time. We investigate an above-ground population following a Fisher-Wright model with selection coupled with a deterministic seed bank assuming the length of the seed bank is kept constant and the number of seeds is large. To assess the combine...
