Abstract

Our study comparative analyzed the morphological and physiological performance of Juglans regia L. cv. ‘Xiangling’ (JRX) grafted onto five rootstock species originated from China. A wide range of coefficient of variation (CV), 1.155–39.848%, was detected for fourteen indexes among the studied seedlings. CV of plant height, total dry biomass, total leaf area, root/shoot ratio, chlorophyll index, and stomatal conductance was higher than 15.00%, suggesting higher variation. Principal component analysis, hierarchical cluster analysis and subordinate function analysis were used to screen engrafted seedlings for their quality. All three methods produced the same result that seedling quality of ‘Xiangling’ engrafted with the five rootstock species from high to low were – Juglans regia L. cv. ‘Jizhaomian’ (JRJ), JRX, Juglans regia L. cv. ‘Lvxiang’ (JRL), Juglans mandshurica, Maxim., and Juglans hopeiensis Hu.. The evaluation results were highly consistent with the actual growth performance of the engrafted seedlings, it verified the reliability of our results and the evaluation methods. The results demonstrated that JRJ, JRX, and JRL are potential rootstock candidates in the studied walnut planting regions. It would provide important implication for the selection of proper rootstock species for a certain particular walnut variety.

5种砧木对核桃生长、气体交换和叶绿素荧光的影响。“Xiangling”

本研究对核桃的形态和生理性能进行了比较分析。‘香岭’(JRX)嫁接到五种中国砧木上。14项指标的变异系数(CV)范围为1.155 ~ 39.848%。株高、总干生物量、总叶面积、根冠比、叶绿素指数和气孔导度的CV值均大于15.00%，变异较大。采用主成分分析、层次聚类分析和隶属函数分析对嫁接苗进行质量筛选。3种方法的结果一致，‘香陵’嫁接5种砧木的幼苗质量由高到低依次为:核桃(Juglans regia L. cv);‘吉兆面’(JRJ)， JRX，吉兆面，吉兆面。“绿香”(JRL)， Juglans manshuurica, Maxim。，和Juglans hopeiensis Hu..评价结果与嫁接苗的实际生长性能高度一致，验证了我们的结果和评价方法的可靠性。结果表明，JRJ、JRX和JRL是研究区核桃砧木的潜在候选品种。这对核桃品种的砧木品种选择具有重要的指导意义。
