试验结果表明，金银忍冬和紫珠种子无休眠期。前者在１３℃夜／２０℃昼，暗培养条件下，５天初萌，２２天成苗率达８９％；后者在２０℃夜／３０℃昼，暗培养条件下，９天初萌，２０天成苗率达６３％。鸡树条荚蓬种子在１７～２０℃混湿沙层积９０天后，用ＧＡ３处理９６小时，于２０℃夜／２５℃昼暗培养条件下，５０天初萌，３个星期发芽率达８０％；若用１％或０．５％浓度的ＴＴＣ染色，在３５℃下，分别染色６小时和９小时，均能获得良好效果。
The test results show that the honeysuckle honeysuckle seeds and seeds no dormant period. The former under the conditions of 13 ℃ night / 20 ℃ day and dark culture conditions, 5 days early adorable, 22 days into the seedling rate of 89%; the latter at 20 ℃ night / 30 ℃ day, dark culture conditions, 9 days adorable, 20 Seedlings rate of 63%. The seedlings of P. chinense were treated with GA3 for 96 hours at 17-20 ℃ for 96 days, and then germinated at 50 days in 20 ℃ night / 25 ℃ dark day. The germination rate reached 80 in 3 weeks %; Good results were obtained with TTC staining at 1% or 0.5% concentration at 35 ° C for 6 and 9 hours, respectively.
