剑阁柏木(Cupressus Jiangeensis N. Chao)是在剑阁古驿道两旁的行道树一“皇柏树”中发现的,仅有1株。该树种枝叶向上挺拔,远看似松,近看为柏,果实形如松果,果鳞形状和一般柏木(Cupressus funebris)相近,当地群众形象地叫它“松柏树”。为尽快选育出柏树良种类型,防止基因丧失,从1978年以来,我们开展了对该树种的试验研究。一、形态特征剑阁柏为常绿高大乔木,树高27米,枝下高17.7米,根径1.29米,胸径1.16米;树皮褐 Cupressus Jiangeensis N. Chao is found in the “cypress tree” on both sides of the Jiange Ancient Post Road, with only one plant. The branches of the tree grow upright, seemingly loose from the distance, near the cypress, fruit shaped like a pine cone, scale and shape similar to the common cedar (Cupressus funebris) similar to the local people vividly call it “cypress.” In order to breed cypress tree varieties as soon as possible to prevent the loss of genes, we have carried out experimental research on the tree species since 1978. First, the morphological characteristics Jiange Parker evergreen tall trees, 27 meters high, branches 17.7 meters high, 1.29 meters in diameter, diameter 1.16 meters; bark brown
