%X Zhangwu pine (Pinus densiflora var.zhangwuensis) is a natural hybrid of P.densiflora.Studies show that Zhangwu pine has full terminal buds,with high survival in grafting.The diameter and height of 1 and 2-year-old seedlings are larger than those of P.sylvestris var.mongolica,V.densiflora and P.tablaeformis.The heights of 2-year-old seedlings are 36%,51 % and 33%,respectively,higher than that of the latter three pines.The 11-year-old trees of Zhangwu pine is significantly larger than those of P.sylvestris var.mongolica,with 82% higher in height and 47% bigger in diameter.Zhangwu pine is also resistant to drought and disease,so it is a promising variety for afforestation in the Three-north Region,and worthy of propagation and extension.
