中间砧对“茂谷橘橙”树体和果实品质的影响

以蕉柑、芦柑和改良橙作为茂谷橘橙的中间砧，对各中间砧组合的亲和性、树体及枝梢生长表现、产量和果实品质等进行比较研究，结果表明，3种中间砧与接穗的亲和性无显著差异，均表现为亲和力强；改良橙作中间砧的冠径，春梢、夏梢、秋梢的生长量和早期产量均显著地低于蕉柑、芦柑的。高接5年后，3种中间砧对产量的影响无显著差异。3种中间砧对茂谷橘橙果实外观品质和内部品质的影响都不明显。

Effects of Interstocks on the Tree Character and Fruit Quality of Citrus Variety 'Murcott'

Tankan (Citrus reticuiata Blanco cv, Tankan), Ponkan (C. poonensis Hort. ex Tanaka), Gailiangcheng (C. sinensis Osbeck cv. Gailiangcheng) as the interstocks for Murcott (C. spp) was used for studying compatibility of interstocks with up and down stocks, growth of trees and sticks, yield of interstocks and fruit quality. The following results were obtained: The compatibility between the three kinds of interstock and the scion had no remarkable difference. Gailiangcheng had significantly smaller crown diameter, spring shoots, summer shoots, autumn shoots and the early stage yield than that of the other two. The yield had no remarkable difference among three kinds of interstock after grafted five years. The fruit external characters internal quality of Murcott had no remarkable difference among three kinds of interstock.
