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 200mg·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 100mg·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。

摘  要：
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.
