- 摘要:
- 刺茄种子在常规条件下很难萌发。为寻找促进刺茄种子萌发的试剂，试验以不同浓度的赤霉素（0~1 000 mg/L）和双氧水（0%~3.0％）溶液处理刺茄种子，观察记录每天的发芽数，并从种子的发芽率、发芽势、发芽指数3个指标探讨赤霉素和双氧水对种子萌发的影响。结果表明：双氧水和低浓度赤霉素（0~400 mg/L）对刺茄种子的萌发没有影响，而高浓度赤霉素（600~1 000 mg/L）能显著提高种子萌发。
- Abstract:
- Under the normal natural conditions，the seeds of Solanum aculeatissimum have a pretty low germination rate.In order to find a suitable treatment to accelerate the germination rate，two reagents of gibberellic acid (GA，0-1 000 mg/L) and hydrogen peroxide solution (H2O2，0%-3.0%) with different concentration gradients were used to deal with the seeds.The numbers of sprouted seeds were gathered daily.Three indicators of the germination rate，germination potential and germination index were employed to study the effect of GA and H2O2 on the seed germination.The results showed that，H2O2 and GA with low concentration(0-400 mg/L） had little effect on the seed germination，while GA with high concentration(600-1 000 mg/L) significantly promoted the germination of Solanum aculeatissimum.
