摘  要：
为解决三倍体西瓜种子的萌发问题,以三倍体西瓜种子为材料,研究了不同浓度的水杨酸(SA)引发处理对三倍体西瓜种子萌发及其种子浸出液电导率的影响。结果表明:在SA浓度为0.01~1.0mmol/L范围内浸种处理可明显促进三倍体西瓜种子的萌发,其发芽势、发芽率、发芽指数、活力指数呈增长趋势,其中0.1mmol/L的SA处理24h效果极为显著。而当SA浓度高于1.0mmol/L时则对种子的萌发起抑制作用,其各项萌发指标均随SA浓度的增加而明显下降。SA浸种后三倍体西瓜种子浸出液电导率的变化同种子萌发的趋势相似,较低浓度SA可显著降低种子浸出液的电导率,此后随SA浓度的升高呈明显下降趋势。

摘  要：
For overcoming germination problem of triploid watermelon seeds, triploid watermelon were selected as material to study the effect of soaked with different concentrations of salicylic acid (SA) priming to their germination rate and conductivity of seeds lixivium. The results showed that SA at 0.01-1.0 mmol/L concentration significantly promoted germination and conductivity of seeds lixivium, such as germination energy, germination rate, germination index, vigor index were increased. The concentration at 0.1mmol/L SA treated for 24 h showed the best. However, when the concentration of SA went beyond 1.0 mmol/L, the germination seed was inhibited. It each germination target clearly decreased with increasing concentration of SA. The tendency was similar that conductivity of seeds lixivium and germination after soaking with SA. The conductivity of seeds lixivium of change was decreased at lower concentration. It was the obvious drop tendency with increasing when the concentration of SA.
