以白玉兰、紫玉兰、乐昌含笑、深山含笑作砧木的阔瓣含笑嫁接苗为材料,通过对嫁接苗生长特性的观测和生理生化指标的动态测定,运用主成分分析和隶属函数法计算亲和性综合指数,评价阔瓣含笑与4种砧木的苗期亲和性。结果表明:以深山含笑和紫玉兰作砧木的嫁接成活率较高(分别为88.33%、83.33%),白玉兰次之(为75%),乐昌含笑较低(为63.3%);砧木对嫁接苗的苗高有较大影响,以深山含笑和紫玉兰的苗高最高,白玉兰次之,乐昌含笑最矮;砧木对嫁接苗叶片数的影响表现为初期存在一定差异,生长后期差异逐渐缩小。在嫁接苗生长过程中,4种砧木嫁接苗的叶绿素含量均呈双峰型变化,类胡萝卜素含量、可溶性蛋白含量、...

Mchelia platypetala was taken as scion, seedlings of Magnolia denudate, M. liliflora, Michelia chapensis and M. maudiae were taken as rootstock, those four kinds of grafted seedlings were used as experimental materials in this study. Based on the measurement of growth and physiological indexes, we initially evaluated the compatibility between M. platypetala and four rootstocks by principal component analysis and subordinate function(SF) method. The results showed that, M. maudiae enjoyed the highest survival rate of 88.33%, while the second one was Magnolia liliflora with 83.33% survival rate ...
