刺槐(Robinia pseudoacacia Limn·)是华北,西北和华东、东北部分地区营造用材林,水土保持林,防护林和四旁绿化的重要树种。近年来,通过选育和初步鉴定。已选出一批优良类型和单株,如能采用组织培养法,就可繁育大批优良无性系,缩短良种繁育周期,快速投入生产,这对促进林业生产的发展,具有现实意义。 我所经过1977、1978年的试验,用刺槐幼嫩的茎、叶片、叶柄,诱导出完整植株。1977年用嫩叶培育出具有14个小叶的完整植株,1978年、1979年培育出一批刺槐绿苗。(见附页照片二～六)。移栽后成活,生长正常(见附页照片一)。现将我们的工作简要总结如下:
Robinia pseudoacacia Limn. Is an important tree species for planting timber forests, soil and water conservation forests, shelter forests and greening in all parts of northeast China in North, Northwest and East China. In recent years, through breeding and preliminary identification. A large number of fine types and single plants have been selected. If a tissue culture method can be used, a large number of excellent clones can be bred, the breeding cycle of breeding seeds can be shortened and production can be quickly put into production, which is of practical significance for promoting the development of forestry production. After 1977-1978 experiments, I used the young stems, leaves and petiole of black locust to induce the complete plant. In 1977 with the tender leaves to cultivate a complete plant with 14 leaflets, in 1978 and 1979 to cultivate a group of black locust seedlings. (See attached photos two to six). Survival after transplanting, normal growth (see attached photo 1). Here is a brief summary of our work:
