摘要
为提高‘无核白鸡心’葡萄果粒大小,改善果实品质,以3年生‘无核白鸡心’葡萄为试材,研究不同距地面高度、不同结果部位,不同花穗整形方式的处理组合,对果实外观性状和果实品质的影响,并采用主成分分析法对各项指标进行综合评价。结果表明,处理7除穗重、果穗纵径及可滴定酸含量外,其单粒重、果实横径、果实纵径、可溶性固形物含量等各项指标均达到了最大,且效果最好的前4个处理均为结果部位距地面高度80~120 cm,所有进行花穗整形的处理均优于对照。根据综合评价得分由高到低排序为处理7>处理8>处理10>处理11>处理13>处理1>处理16>处理14>处理4>处理2>处理17>处理5>处理12>处理9>处理15>处理18>处理3>处理6。综上结果部位距地面高度80~120 cm,果穗在枝条的基部,花穗上部疏除1/4的处理7是筛选出的可以提高‘无核白鸡心’葡萄果粒大小,改善果实品质的最优处理。
In order to improve the grain size and fruit quality of‘Centennial Seedless’grape.This study used the 3-year-old‘Centennial Seedless’grape as test materials,the effects of different heights from the ground,different fruiting parts and different fruiting positions on fruit appearance and fruit qualities were studied.The principal component analysis method was used to comprehensively e valuate the various indexes.The result showed that,the single berry mass,berry width,berry length,soluble solid and other indexes of treatment 7 was reach the maximum,except mass per ear,ear longitudinal diameter and titratable acid content.Bunch of grapes were 80-120 cm from the ground,the tassel was at the base of the branch,and the tassel top was sparsely removed for 1/4 of the tassel.The top four treatment with the best effect were all the fruits from the height of 80-120 cm from the ground.All the treatments of floral cluster pruning were better than the control.The best treatment was that the height of the fruit part is 80-120 cm from the ground,the ear was at the base of the branch,and the upper part of the ear was thinning 1/4.Treatment 7 was the optimal treatment which could improve the grain size and fruit quality of‘Centennial Seedless’grape.
