保定地区几个早熟苹果品种(系)生长观察

Growth and Fruit Performance of A Few Early Riping Apple Cultivars(Strains) in Baoding Area

为筛选适宜保定地区栽植的早熟苹果品种,以嫁接在SH40中间砧上的不同早熟苹果品种（系）为试材,测定了不同品种（系）早熟苹果树体生长发育指标和果实品质。结果表明：除嘎啦早熟变异外,其他供试品种（系）树体生长较好,3年生时Xu2-7、Xu3-2树高330.0~352.5 cm,4年生时为394.0~417.5 cm,Xu3-2、藤牧1号、信浓红4年生为336.5~381.0 cm。4年生时,干径以Xu2-5最大;短枝、中枝、叶丛枝均以Xu2-5最多,长枝以Xu2-7最多,总枝量以Xu2-5最多;藤牧1号短枝所占比例最高（57.4%）。应用模糊综合评判法得出Xu2-5、Xu2-7、信浓红、藤牧1号果实品质较高。

In order to screening proper early riping apple cultivars in Baoding area,a few early riping apple cultivars（strains ） grafted on interstock SH40 were used to investigate the tree growth and development index and fruit quality. The results showed that these cultivars（strains） grew very well apart from Gala variation. The three years old trees height of Xu2 -7 and Xu2 -5 could reach 330. 0—352. 5 cm and the four years old trees height could reach 394. 0—417. 5 cm,the tree height of Xu3 - 2,Cinano Red and Mato 1 could reach from 336. 5 cm to 381. 0 cm. When the trees were four years old,Xu2 - 5 had the biggest stem diameter,the Xu2 - 5 had the largest number of short shoot,middle shoot and leafage shoot, Xu2 - 7 had the largest number of long shoot,Xu2 - 5 had the largest number of total shoots,the short shoots ratio of Mato 1 was the highest with 57. 4% . The fruit quality of Xu2 - 5,Xu2 - 7,Cinano Red and Mato 1 were relatively higher than other two cultivars（ strains） according to the fuzzy comprehensive evaluation.
