自从1958年斯蒂瓦尔特(Stewarlt)通过胡萝卜的组织培养获得第一批植物试管苗以来,距今已二十多年。全世界已有很多植物种类通过组织培养获得无性繁殖系,其中仅观赏植物就有600多种,而树木种类也有124种,不少农业和园艺上的植物种类已通过试管繁殖大量生产优质苗木。比起农业和园艺来,林木组织培养应用于生产实践上的工作就显得很落后了。其原因很多,主要的是现存的一套组织培养技术比较复杂,如培养基的筛选、人工培养室的
It has been more than twenty years since Stewarlt obtained the first plant test tube plantlets in 1958 through the tissue culture of carrots. There are many plant species in the world that have obtained clonal propagation through tissue culture. Among them, there are over 600 species of ornamental plants and 124 species of trees. Many agricultural and horticultural plant species have produced large numbers of high quality seedlings through in vitro propagation. Compared with agriculture and horticulture, forestry tissue culture applied to the production of practical work is very backward. There are many reasons for this, mainly the existing set of tissue culture technology is more complex, such as screening medium, artificial training room
