番木瓜种子用KNO_3或GA_3溶液浸泡15分钟,其出苗率以及达到50%的出苗率所用的时间比水浸的分别有所提高和减少.35℃盆栽的种子出苗率比25℃盆栽的高.在种子干燥前或经过两周干燥后浸泡KNO_3或GA_3溶液,对KNO_3或GA_3的效果都没有改变.KNO_3处理过的种子,其植株生长表现一般,然而经GA_3处理过的种子,其植株的下胚轴较长.
The immersion rate of papaya seed with KNO3 or GA3 solution for 15 minutes resulted in the increase and decrease of the emergence rate and the emergence rate of 50% compared with that of water immersion.The seed germination rate of potted plants at 35 ℃ was higher than that at 25 ℃. The effect of KNO 3 or GA 3 did not change before or after the seeds were dried for 2 weeks or soaked in KNO 3 or GA 3 solution.The growth of KNO 3 -treated seeds was general, however, the GA 3 -treated seeds had lower Hypocotyl longer.
