| Abstract: | After pruning the mother trees in Pinus masoniana improbed seed orchard with 1Bole,3Forks,9Tips and 27Branches,Compared 12-year-old mother trees of improved generation Pinus massoniana seed orchard with that of first-generation Pinus massoniana,the average tree height decreased by 20%,height under branch decreased by 53.8%,crown width increased by 7.7%,costs of seed collection decreased by 51.8%,average cone yield per tree increased by 138.3%,and increased by 60% yearly.This could realize good quality and high yield for seed production. |
