板栗是异花授粉植物,植株之间的物侯期、生育状况、产量高低,品质及其它特性,均存在显著的差异。我省板栗历年来大都采用实生繁殖,致使后代植株之间变异多样,优劣悬殊。据调查,不同单株之间,果实成熟期相差一月之久。栗果的大小,亦由每0.5公斤20粒到90粒不等,产量差距更甚,低产树单株不满5公斤,而高产树可达50公斤以上。从这些变异中,选出具有高产、稳产及优质特性的优株,作为采穗母株,加以
Chestnut is cross-pollination plants, plant Hou period, fertility status, yield level, quality and other characteristics, there are significant differences. Chestnut in our province over the years mostly use real-life breeding, resulting in the diversity of offspring plants varied, the advantages and disadvantages. According to the survey, between different plants, fruit maturity of a month long difference. The size of the chestnut also ranges from 20 grains to 90 grains per 0.5kg, and the difference in yield is even worse. The low-yielding tree is under 5kg per plant, while the high-yielding tree can reach over 50kg. From these mutations, we selected the elite with high yield, stable yield and good quality,
