| 摘 要： | 以鄂西红豆古树和初果树种子为材料,采用不同温度热水分别对两批种子进行浸种处理,再在圃地上进行播种发芽试验。结果表明:古树批种子发芽率高低的顺序为始温90℃热水浸种24h始温80℃热水浸种24h始温70℃热水浸种24h始温60℃热水浸种24h;初果树批种子发芽率高低的顺序为始温80℃热水浸种24h始温70℃热水浸种24h始温90℃热水浸种24h始温60℃热水浸种24h。古树批种子用始温90℃热水浸种24h处理方法发芽率最高,达84%;初果树批种子用始温80℃热水浸种24h处理方法发芽率最高,达85%。相同方法处理的种子(除始温90℃热水浸种24h外),初果树批种子比古树批种子的发芽率高。用90℃高温热水浸种处理,会造成初果树种子烫伤,严重影响发芽率,而古树种子不受影响。

| Abstract: | Taking ancient trees and young growing period of Ormosia hosiei in western Wuhan City as materials, two batch of seeds were soaked by adopting hot water at different temperatures,seed-sowing experiments were con-ducted in the nursery.Result shows that the descending order of seed germination of the batch of ancient trees is seeds soaked in 90 ℃ hot water (starting temperature)with 24 h> seeds soaked in 80 ℃ hot water (starting tem-perature)with 24 h> seeds soaked in 70 ℃ hot water (starting temperature)with 24 h>seeds soaked in 60 ℃ hot water (starting temperature)with 24 h;the germination rate of seeds (batch of young grouing period)soaked in 90℃ hot water (starting temperature)soaked with 24 h is the highest,being 84%;the germination rate of seeds (batch of young growing period)soaked in 80 ℃ hot water (starting temperature)soaked with 24 h is the highest, being 85%.Germination rate of seeds (batch of young growing period)is higher than that of the seeds (batch of ancient trees)under the same treatment ,except 90 ℃ (starting temperature)soaked in hot water with 24 h.Soa-king seeds in the hot water (90 ℃)can burn the seeds of young growing period,seriously affecting the germination rate and the seeds of ancient trees are not affected. |
