Abstract

The germination rate of seeds of Securigera securidaca varied abruptly from 0% to 100% in different years of maturation, and this variability did not seem to be due to climatic differences during the period of seed maturation. These seeds showed also polymorphism in colour, which appeared to be related with varying depths of dormancy. This last one seemed to be increased by a short ageing of the seeds.

摘要

硬毛棘豆种子的发芽率在不同成熟年份中从0%急剧变化到100%,这种变异性似乎并非由于种子成熟期间的气候差异所致。这些种子在颜色上也表现出多态性,这似乎与不同的休眠深度有关。最后一点似乎因种子短期老化而增加。
