不同品系杉木幼苗侧枝生长发育的比较研究
Comparative study on growth and development of lateral branches of different types of Cunninghamia lanceolata
为筛选出株型良好、侧枝条件优良的杉木幼苗,在福建农林大学温室大棚内种植三个不同品系杉木一年生幼苗(洋 020无性系组培苗、洋 061无性系组培苗和湖北罗田垂枝杉)作为研究对象,测量其苗木生长量、侧枝生长指标,比较不同品系杉木侧枝发育的差异,分析杉木侧枝生长的相关性。结果表明:(1)平均苗高、地径、高径比在三种不同品系杉木幼苗间均有显著差异,洋 020以高度生长为主,垂枝杉以地径生长为主;(2)侧枝轮数、数目、长度、角度在三个不同品系杉木间均存在显…查看全部>>
In order to select the seedlings of Cunninghamia lanceolata with good plant type and excellent conditions of lateral branch,A plantation with three different strains of annual seedlings of Cunninghamia lanceolata(tissue culture seedling of yang-020 clones,yang-061 clones and Cunninghamia Lanceolata cv.Luotian)were planted in the greenhouse of Fujian agricultural and Forestry University.The seedling growth and lateral branch growth index were measured,and com…查看全部>>
