Although cold stratification requirements for dormancy break vary among species, it is not known if this variation is determined by the environmental conditions experienced by seeds or by differences among species.Methods We determined the soil moisture content and duration of cold stratification required...
For example, maybe you buy seeds and go to the trouble of sprouting them indoors and planting the resulting starts where and when they'll be most likely to succeed. That's great—but you could be skipping what is an essential step for lots of seeds: cold stratification. Many seeds require...

Germination of seeds of some summer annuals in Kentucky (eastern USA) in late-winter lead to the hypothesis that under present climate conditions the whole length of the winter cold stratification (CS) period is not required for dormancy-break of seeds of summer annuals with physiological dormanc...
Two unrelated dormancy-releasing treatments were applied to dormant seeds, namely, cold stratification and exogenous nitrates, in combination with differential proteomic tools to highlight the specificities of the imbibed dormant state. The results reveal that both treatments lead to highly similar ...
Fluctuation of H2O2 and protein carbonylation seems to play a pivotal role in seed dormancy alleviation by cold stratification, while NO appears to be necessary for seed germination. Introduction Dormancy is a temporary block of viable seeds to complete germination. Dormant seeds cannot germinate even...

The effect of the duration of the initial warm phase (0–32 weeks), as well as the temperature of the warm (15–25°C) and cold (1–5°C) stratification phases, on germination of mountain-ash seeds, has been studied. DOI: 10.17660/ActaHortic.1988.226.27 被引量: 20 年份: 1988 ...
The effect of cold stratification, seed coat scarification and plant hormones on germination of black and brown seeds of under saline conditions was investigated. Cold stratification increased the germination rate, but did not affect final germination percentage of either brown or black seeds. Seed coa...
