Effects of Different Litchi Rootstocks on Phonological Phase and Fruit Qualities of Grafted Jingganghongnuo

摘要

cqvip:Phonological period and fruit quality of Jingganghongnuo( JGHN) grafted on the rootstocks of Feizixiao( FZX),Heiye( HY) and Huaizhi( HZ) respectively were recorded and comparatively studied from 2015 to 2017. The results showed that the whitish millets and flowering stage of JGHN grafted on FZX and HY rootstocks were respectively 3-17 days and 1-3 days earlier than those on HZ. While the fruit maturation stage was 5-7 days ahead of in the same comparative situation. Compared to fruits grafted on HZ,mean fruit weight of JGHN grafted on HY and FZX were 38. 1% and 35. 8% bigger respectively than that on HZ.In addition,more closely heart-shaped and brighter pericarp color of JGHN fruit were observed with rootstock of HZ than that with other two kinds of rootstocks. In terms of aborted-seed rates of JGHN,average value with rootstock FZX was 81. 7%,which was 58. 0% higher than that with HY,and 2. 49 times of those with HZ.Vc content of JGHN grafted on HY and FZX were 30. 47 and 25. 86 mg/100 g respectively,significantly higher than that grafted on HZ. TSS and TA of JGHN grafted on HZ were 17. 8% and 0. 14%,both were obviously higher than that grafted on FZX and HY.
