摘要
利用恒温(30℃)抽真空密封贮藏研究贮藏时间对大豆种子活力和若干性状的影响。结果表明:随大豆种子贮存时间的延长,其发芽率、出苗率、株高、底荚高、主茎节数、有效荚数、单株粒重有降低的趋势,出苗期和开花期推迟,无效荚有增多的趋势,分枝数变化无明显规律性。相关分析显示,大豆种子活力与株高达极显著或显著正相关,而与出苗期和开花期达极显著或显著负相关。株高的降低主要是由于底荚高和主茎节数的减少所致。种子活力与其它性状间的相关系数,不同大豆基因型间差异显著。
Seed vigor and some characters of soybean were investigated after pretreatment with hermetically sealed and vacuumed storage for different time under 30℃. The result showed that the germination percentage, emerging percentage, height of plant, height of bottom pod, number of nodes on main stem, number of valid pods and seed weight per plant were reduced, emerging stage and flowering stage were delayed, number of invalid pods were increased, and number of branches did not changes significantly with prolongation of storage time. The correlation analysis indicated that there was a significantly positive correlation between seed vigor and height of plant, and seed vigor had a significantly negative correlation with emerging stage and flowering stage. The decline of height of plant was mainly caused by the decrease of height of bottom pod and number of nodes on main stem. There were significant differences in the correlation coefficients between seed vigor and other characters in different soybean cultivars.
