矮壮素及烯效唑对甜椒幼苗质量的影响
Effects of Chlormequat and Uniconazole on Seedlings Quality in Sweet Pepper
摘要
Abstract
Chlormequat and uniconazole belong to delayed plant growth regulators that can inhibit the biosynthesis of gibberellins and slow down the cell elongation. In order to control the excessive growth of sweet pepper plug seedlings and improve the quality of seedlings, large fruit sweet pepper Retian No.4 was treated with different concentrations of chlormequat and uniconazole for analyzing the effects on seedlings quality. The results showed that 200~1 000 mg/L 50% chlormequat and 20~100 mg/L 5% uniconazole could significantly inhibit the plant height, increase stem diameter, reduce leaf area, increase root-shoot ratio, and enhance the activity of SOD and POD enzyme. The inhibition effect of uniconazole was significantly higher than that of chlormequat. 400 mg/L 50% chlormequat or 60 mg/L 5% uniconazole was a suitable concentration for spraying that could improve the quality of sweet pepper seedlings significantly.关键词
