Effect of Pollination Varieties on Fecundity and Fruit Quality of Blackberries'Freedom'
摘要
Abstract
In order to investigate the effects of pollen xenia on the fruiting and fruit quality of'Freedom'blackberry,this study used'Freedom'as the recipient and conducted artificial pollination with four male parent varieties,including'Ark-45','Erika',Rubus eustephanos and Rubus peltatus.Comprehensive analysis and evaluation were performed on fruiting,fruit quality,and seed-related indicators.The results indicated that'Freedom'exhibited pollen xenia.The fruit setting rate(54.49%-86.01%),single fruit weight(0.87-11.28 g)and soluble solids(8.59%-16.53%)of different male parents were significantly different.Principal component analysis extracted three principal components,with a cumulative contribution rate of up to 95.55%,reflecting indicators such as fruit size,flavor,and seed size.The comprehensive evaluation showed that the pollination effect of Rubus peltatus(comprehensive score 1.94)and Rubus eustephanos(1.88)was the best,followed by'Ark45'(0.41)and'Erika'(0.09).In summary,Rubus peltatus and Rubus eustephanos are suitable pollinating varieties of'Freedom'blackberry,and the xenia effect of pollen can effectively improve its comprehensive quality.In the future,ploidy analysis and physiological mechanism research can be combined to clarify the regulation path of pollen xenia,so as to provide more accurate support for pollination configuration and quality improvement of blackberry.关键词
