摘要
梭梭种子发芽的适宜pH值范围较宽(7~11),梭梭种子在水中浸泡1hr后种皮透性开始有较明显的增大,浸泡7hr后外修速率减慢,浸泡21hr后渗透基本达到平衡.NaCl和6—BA促进种子萌发,KCl、KNO和α—NAA影响胚的伸展.梭梭种子中含有内源性抑制物,其R值为0.29~0.39.
The suitable range of pH for germination of Haloheon Ammodrndron is comparativily wide (7-11).After soaking the seeds in water for 1 hr.,we found the seepage of the seeds coat began to rise obviously.This seepage aetion would slow down after being soaked for 7 hours and get a balance basically after 21 hours, NaCI and 6-BA could accelerate Remination of seed. KCI, KNO3 and α-NAA would affect the extension of embryo. There was a internal inhibitor in the-seeds and its Rf was fromO. 29 to O. 39.
