沙田柚自花结实率低,需异花授粉才能正常结实。我区栽培的沙田柚有正形、条叶、阔叶三个品系,它们在生长习性、枝叶形态和果实性状等方面均有显著差异。1986年我们对沙田柚不同品系间授粉的结实能力进行了试验。现简报如下: 一、材料与方法 于遂宁市市中区粮食原种场选择生长正常的正形沙田柚、阔叶沙田柚、条叶沙田柚成年树各3株 Shatian pomelo self-cultivation rate is low, cross-pollination required to be normal and strong. Shatian pomelo cultivated in our district has three varieties of positive, leaf and broadleaf, which have significant differences in growth habits, branch and leaf morphology and fruit traits. In 1986, we tested the ability of pollination between different lines of Shatin pomelo. Now briefings are as follows: First, materials and methods in Suining City grain Zhongyuan District, the normal growth of the selected shape of Shatian pomelo, broad-leaved Shatian pomelo, leaves three adult trees Shatian pomelo
