摘要
对六个冬小麦品种（系）不同采收期的种子进行了水分、鲜干种子发芽及休眠性测定。结果表明：鲜种子的萌发率随发育程度而提高，在生理成熟前后达到最高值，并与其水分含量高度负相关，干燥可显著地促进未熟种子的萌发；种子的休眠性随发育程度的提高而减弱，17DAA（花后天数）以后采收的种子没有休眠性。
The determinations of moisture concentration, germination and dormancy of the seeds collected at different developing stageswere done on six winter wheat varieties or lines. The results are as follows:Significant negative correlation existed between germi-nation percentage and water content of fresh seeds. Germination percentage of fresh seeds increased with seed development, andreached the top level at about PM. Desiccation could promote better germination of the immature seeds. Dormancy of seeds reducedwith seed developing process and disappeared on 17 DAA.
