矮壮素处理对荠菜生长的影响

Effect of Chlormequat on the Growth of Capsella bursa-pastoris

为了解不同浓度矮壮素对荠菜生长的影响,用100~600mg/L矮壮素及清水做对照,喷施荠菜叶片。结果表明,喷施适当浓度矮壮素有利于抑制荠菜抽薹、促进生长、提高产量,当矮壮素处理浓度为233.3mg/kg时,荠菜产量最高;矮壮素浓度过高时,会抑制荠菜生长,导致产量下降。

In order to study the effect of different concentrations of chlormequat on the growth of shepherd's purse,100-600mg/L chlormequat and water were used as control.The results showed that appropriate concentration of chlormequat could inhibit bolting,promote growth and increase yield of Capsella bursa-pastoris,when the concentration of CCC was 233.3mg/kg,the yield was the highest.But high concentration of chlormequat could inhibit the growth and of Capsella bursa pastoris.
