摘要/Abstract

摘要： 研究植物生长调节剂种类、用量及品种3因素作用下对景天科多肉叶片扦插繁殖效应，运用隶属函数法对各处理的扦插效果进行评价，并比较品种间繁殖效果差异。结果表明：叶片扦插生长指标主要受3个主因素效应及用量×品种交互效应影响。4个品种之间生长指标的差异均达到显著水平（P<0.05）。厚叶月影、蓝苹果和黑爪叶插繁殖最适宜的植物生长调节剂处理是NAA 200 mg·L^-1，隶属函数值分别为0.95、0.90、0.90；露娜莲叶插繁殖最佳处理是IBA 100 mg·L^-1，隶属函数值为0.84。品种间繁殖效果差异显著，蓝苹果生根率和移栽成活率最高，分别为91.54%、99.01%，黑爪萌芽率最高，达97.33%。4个品种的扦插苗移栽成活率均在90%以上，比对照提高6.26%~22.99%，说明NAA或IBA对景天科多肉植物叶插繁殖有促进作用，成活率高且经济快捷。

Abstract: Propagating Crassulaceae by using cut leaves from the plants with treatment of growth regulators was studied. Applying the subordinate function method, the effects of two types of hormones on 4 varieties of Crassulaceae were evaluated. The results showed the application of 200 mg·L^-1 NAA on Echeveria elegans var. Kesselringiana, xSedeveria (Blue Elf) and Echeveria cuspidata var. zaragozae Kimnach yielded the desirable effect with subordinate function value of 0.95, 0.90 and 0.90, respectively; while, that of 100 mg·L^-1 IBA on Echeveria (Lola) with a subordinate function value of 0.84. The growth indices of the leaf-cuttings were significantly different between varieties (P<0.05). The 91.54% rooting and 99.01% survival rates of Blue Elf and the 97.33% germination rate of E. cuspidata were the highest among all varieties studied. The seedling survival rates of the 4 varieties were all greater than 90%, which were 6.26%-22.99% higher than control. It indicated that either NAA or IBA could be used effectively and economically to promote the Crassulaceae propagation from cut-leaves.
