扦插条件对“贵安尚菊”种苗繁殖及其植株产花量的影响

Effects of Cutting Conditions on Seedling Propagation and Flower Yield of “Guianshang Chrysanthemum”

摘要: 本文以江西“晓起皇菊”成功引种到贵州的“贵安尚菊”头年脚苗为材料，从扦插时间、插穗类型两个方面对“贵安尚菊”种苗扦插繁殖及其植株产花量的影响进行研究。研究结果表明扦插时间对“贵安尚菊”种苗扦插繁殖有显著的影响；插穗类型对“贵安尚菊”种苗繁殖无显著影响，与扦插时间存在互作效应；“贵安尚菊”植株获得最高产花量的插穗为除顶端幼茎段，最适扦插时间是4月。

Abstract: Using the first-year foot seedlings of Guianshang chrysanthemum, which was successfully introduced from Jiangxi “xiao qi huangju” to guizhou, this paper studied the effects of cuttage time and type of cuttage on the cuttage propagation and flower yield of Guianshang chrysanthemum. The results showed that cutting time had significant effect on cutting propagation of “Guianshang chrysanthemum”. There was no significant effect of the type of cuttings on the propagation of “Guianshang chrysanthemum” seedlings, and there was an interaction effect with the cutting time. The cuttings of “Guianshang chrysanthemum” plants with the highest flower yield were the young stem segments except the top, and the optimum cuttage time was April.
