| 摘 要： | 对张广才岭西北麓次生林内槲寄生的寄主树种和数量分布状况进行了调查分析。结果表明,张广才岭次生林中槲寄生的主要寄主树种为杨树、椴树和榆树,其他树种很少;单株簇生是槲寄生的主要着生方式,2,3,4和5株簇生有一定数量,6株以上簇生的已经微乎其微;槲寄生主要着生在寄主树体的上、中部和侧枝上,不同树种的表现不尽相同;阳坡、坡下部、平坡和农田边的次生林中槲寄生的数量相对较多。

| Abstract: | The species of host tree to Viscum coloratura （ Kom. ） Nakai and their quantity distribution patterns were investigated in secondary forest in northwest area of Zhangguangcaihng Mountains. The results indicated that main host tree species to V. coloratum in the investigated region were poplar, Tilia and Ulmus, and other species is much less planted; single plant as one group was the main insertion pattern of V. coloratum, and 2, 3, 4 and 5 plants as one group was distributed in a certain quantity, but more than 6 plants as one group was very little; V. coloratura plants mainly grew on upper and middle parts of host tree crown and on twigs and branches with somewhat difference among tree species; there are more V. coloratum plants in secondary forest located on sunny slope, foothill, level site and cropland side. |
