池杉自本世纪初至一九二六年,先后引入我国上海、南京、南通,武汉大学、庐山植物园等处栽培。由于它生长快、材质好、冠型美、适应性强,现已列为中南、华东等地区水网湖区四旁绿化重要树种。为了实现池杉造林良种化,促进林木速生丰产优质,我省于一九七二年至一九七四年选出优树35株,用于建立种子园。为了使根据表型选择的优树,通过试验,了解它们之间的差异,并初步鉴别出是由于遗传或环境因素造成,从而尽快地鉴定出遗传优良的无性系,进一步有效地利用这 Iwakami from the beginning of this century to 1926, has introduced China’s Shanghai, Nanjing, Nantong, Wuhan University, Lushan Botanical Garden and other cultivation. Because of its fast growth, good material, crown-type beauty, adaptability, has now been listed as Central South, East China and other regions around the lake green important tree species. In order to achieve afforestation of Ipomoea cunninghala and promote the fast-growing and high-yielding and high-quality trees, 35 species of excellent trees were selected in our province from 1972 to 1974 for the establishment of seed orchard. In order to make optimal tree selection based on the phenotype, we can understand the difference between them through experiments and identify the genetic clone as soon as possible due to genetic or environmental factors, so as to further utilize this
