'西拉'早熟芽变株系的鉴定及其性状、品质分析
Identification,Characterization,and Quality Analysis of the Early Maturing Bud Mutation Lines of'Syrah'
摘要
Abstract
Bud mutation is an important source of genetic variation and cultivar improvement in grapevine.Different bud mutation lines may exhibit distinct characteristics in growth,development,and fruit quality formation.In this study,the common'Syrah'grapevine(CK)and five early-ripening bud mutation lines(SY1-SY5)were used to investigate differences in leaf phenotypes,fruit appearance traits,conventional quality attributes,and phenolic composition.The comprehensive quality of different lines was further evaluated using the TOPSIS method.The results showed that all early-ripening bud mutation lines were better than CK in plant morphological traits,including leaf length,leaf width,leaf weight,and petiole length.Significant differences were observed in the accumulation patterns of sugars,acids,and phenolic compounds among different bud mutation lines.Compared with CK,flavanol contents in the mutant lines varied by ﹣13.3%to 116.9%,with SY3 and SY4 showing increases of 73.2%to 116.9%.Flavonol contents in all mutant lines were higher than those in CK,with increases ranging from 27.8%to 94.5%,whereas phenolic acid contents decreased by 7.7%to 54.3%in all lines except SY5.Analysis of individual phenolic compounds revealed significant differences in the accumulation of epicatechin,catechin,quercetin,gallic acid,ferulic acid,resveratrol,and other phenolic metabolites among different bud mutation lines,indicating distinct phenolic metabolic profiles.TOPSIS evaluation showed that the comprehensive closeness coefficients(C)ranked as follows:SY5＞SY3＞SY4＞SY1＞SY2＞CK,with SY5 exhibiting the highest comprehensive quality performance.These findings indicate that bud mutation alters morphological traits and secondary metabolite accumulation patterns in'Syrah'grapevine,and different mutation lines possess distinct quality characteristics,providing valuable information for the selection and utilization of superior early-ripening bud mutation resources.关键词
