摘要
对栽植在红壤丘陵地的大核青、横核、红面珠墩、鹅嗉等四个青梅品种三年生树的生长结果习性调查表明:大核青树冠扩大最快,横核和红面珠墩次之,鹅嗉最慢;短果枝占各类枝梢比率各品种分别为73.9%、70.2%、31.6%、48.5%;不完全花率各为9.3%、10.2%、8.3%和18.7%;每100朵花的花粉重量分别为86.1、84.2、73.8和64.2mg;第一年结果的单株产量依次为7.25、1.75、0.90、和0.20kg。
Abstract The growing and bearing habit of 3-year old trees of four Prenus mume-cultivars,1.e.‘Daheqing’(DHQ),‘Henghe’(HH),'Hongmianzhudun’(HMZD)and‘ESu'(ES)are recorded. The crown diameter of‘DHQ' is the longest,that of‘HH' and ‘HMZD' are intermediate,and that of ‘ES' is the shortest.The fruit spurrates are 73.9%,70.2%, 31.6%and 48.5%,and imperfect flower rates are 9.3%,10.2%,8.3%and 18.7%,respectively. The amount of pollen per 100 flowers are 86.lmg,84.2mg,73.8mg and 64.2mg,and the yield in the first year are 7.25ks,1.75kg,90 kg and 0.20kg per tree,respectively.Kev words Prunus mume,Spur,Bearing habit
