肥皂草种子的休眠和萌发特性初探

Preliminary Study on Dormancy and Germination Characteristics in Seed of Saponaria officinalis Linn

用刀片切破肥皂草种子的种皮,可以有效地破除肥皂草种子休眠,第2天就达到完全萌发。变温0℃/25℃(12 h黑暗/12 h光照)处理可以有效地促进肥皂草种子的萌发,达到完全萌发需要20 d。

Cutting a bit of the seed coat could break the dormancy of Saponaria of-ficinalis effectively; the germination could reach 99.0% at the second day. 0 ℃/25℃ （12 h/12 h） shift temperature treatment could accelerate the germination of Saponaria officinalis. Under the condition, complete germination needed 20 d.
