3种不同嫁接处理柠檬生长结果习性研究

Study on Features and Bearing Characters of Eureka Lemon Grafted with Three Different Rootstocks

研究了3种不同嫁接处理尤力克/印度莱檬/香橼、印度莱檬/香橼、尤力克/香橼的形态特征、生物学特性、丰产性、抗逆性和品质。结果表明,3种不同嫁接处理嫁接部位基本正常,果实纵横径、果形指数、pH值、糖度、酸度的差异不大,在叶果比、皮厚、可食率、出汁率、丰产性、抗性方面存在差异。尤力克/印度莱檬/香橼在高接换种第4年,表现出较好的丰产性,但早衰现象严重,树体枯枝率高达13.3%,裂皮病达到98.2%,生产上不宜将印度莱檬/香橼高接换种为尤力克柠檬。

Through two years＇ continuous field experiment,Eureka lemon [Citrus limon（L.） Burm.f.]grafted on the different combinations of interstock/rootstock were compared with each other to find out their difference in tree features,resistance and bearing characters.The results indicated that the scion and interstock part of lemon grafted in different treatments had nomal performance.The significant difference in the longitude diameter of fruit,the ratio L/D,pH,sugar content,acid content was not observed respectively in different treatments,but significant differences in the ratio L /F,peel thick,eddible ratio,juice ratio,yield character and resistance,respectively.Eureka/lime/citron had the highest yields but early shorted-fruit life,and the percentage of dead branches accounted for 13.3 % and the occurrence of citrus excocortis virus（CEV）was 98.2 % after 4 yours.So the eureka lemon was not suitble to graft on India lime.
