The results showed that:(1) TX2(‘Xinxiang No.8’/‘Gelafute’) and TX3(‘Xinxiang No.8’/‘Buyeding’) significantly increased the yield of red fruit,and TD2(‘Duojiao’ /‘Gelafute’) showed a relatively obvious increase in yield,but was not at significant level.(2)In the fruit shape,except for ‘Fugenweishi’,other rootstocks showed a tendency to increase fruit in both chili varieties.The fruit length and fruit diameter of TX3 were significantly higher than CK1,which increased by 21.73% and 14.81% respectively.The results of TD1(‘Duojiao’ /‘Yelimu’) and TD2 were higher than CK2 in fruit length,fruit size,fruit shape index,pulp thickness,and fetal width,the fruit shape index and pulp thickness reached a significant level.(3) The dry matter mass fraction of the four treatments(TX1,TX2,TX3 and TX4) was higher than CK1,and the TX1(‘Xinxiang No.8’/‘Yelimu’),TX2 and TX3 reached a significant level. The dry matter mass fraction of TD1,TD2 and TD3(‘Duojiao’ /‘Buyeding’) were higher than CK2,and TD3 was significantly higher.In terms of soluble sugar mass fraction,TX1,TX2 and TX3 were all significantly higher than CK1.The soluble sugar mass fraction of TD1,TD2and TD3 was higher than CK2,and TD3 was at a significant level.In the soluble protein mass fraction of fruit,TX2 and TX3 were significantly higher than CK1 and TD3 significantly higher than CK2.In terms of vitamine C mass fraction,TX4(‘Xinxiang No.8’/‘Fugenweishi’) was significantly lower than CK1,the TD1,TD2 and TD4(‘Duojiao’ /‘Fugenweishi’) were significantly lower than CK2.(4) In four grafting rootstocks,‘Yelimu’ showed a tendency to increase the mass fraction of capsaicin,but it did not reach a significant level,and other rootstocks showed a tendency to lower the mass fraction of capsaicin.The decrease of capsaicin mass fraction in TX3,TX4,TD2,TD3 and TD4 was significant. keywords:Xianlajiao chili pepper  Rootstock  Fruit yield  Quality  Capsaicin 查看全文  查看/发表评论  下载PDF阅读器
