三唑酮与乙蒜素混剂对变叶木插穗生长的影响

Effect of Triadimefon and Ethylicin ixture on the growth of C. variegatum cuttings

用三唑酮6.25%+乙蒜素93.75%混合配制成160mg/L至1600mg/L10种不同浓度的药剂,分别对变叶木插穗浸泡处理后扦插。试验结果表明,最佳处理的插穗生根数、根长、根径的平均值和最高成活率分别为45.2、31.8、1.47、80%,分别比对照提高了9.6、7.4mm、0.36mm、46.67%,所测指标均与对照的差异极显著(P<0.01)。在160～400mg/L范围,处理浓度与插穗的生根数、根长、根径以及成活率的关系符合二次曲线模型(R2>0.97);统计分析结果,处理3h的最佳浓度为291mg/L。

Cutting reproduction experiments of C. variegatum were conducted by dipped treatment of Triadimefon 6. 25% ＋Ethylicin 93. 75% mixture with different concentration from 160 mg/L to 1600 mg/L. The results showed that rooting number of cuttings reached 45. 2, lengths of roots reached 31.8 ram, diameters of roots reached 1.47 remand the highest cuttings survival rate was 80% with the optimal trcatment, and improved 26. 2, 15. 4 mm, 0. 25mm, 60% than other control groups respectively, the difference were very significant between the best treatment and control groups （P〈 0. 01） in the roots of cuttings, lengths of roots, diameters of roots, and survival rate The relationship between the items investigated and trcatment dose during the concentration from 160 mg/L to 400 mg/L fired to the Quadratic model （R^2〉 0. 97）. The statistical analyses indicated that the optimal treatment concentration was 291 mg/L for 3 h.
