摘要
莲子种皮透水性极差,自然萌芽时间长,应用不便,必须进行人工催芽.试验结果表明,经98%H2SO4浸种2 h能有效促进种子的吸水.酸蚀2 h后的莲种子再经300 GA3+10 6-BA和300 GA3+15 6-BA两组外源激素浸种24 h,促进萌发效果最好.处理后发芽率分别为83.33%和80.67%,与对照相比发芽率、发芽势都达到了极显著水平.单独GA3处理与对照相比效果明显,但效果不如上述两组处理.单独6-BA处理与对照相比效果不明显.
Lotus seed has badly property for water permeating. Natural germination is the course of long time and inconvenience. So we have to make accelerating germination. The test results indicate： it can greatly stimulate the seeds drinking if they are dipped in 98 % H2SO4 ahead for 2 h. After being corroded and then treated with 300 GA3＋10 6-BA and 300 GA3＋15 6-BA for 24 h, it has the best effect on stimulating germination. The germination rate has respectively reached 83.33 % and 80.67 %. Germination rate、germination vigor、bud index and simple vigor index have achieved the extremely remarkable level. The effect is obvious separately dipped in GA3, but it isn＇t as good as 300 GA3＋10 6-BA and 300 GA3＋15 6-BA. The effect is not obvious separately dipped in 6-BA.
