匈牙利刺槐(Robinia pseudoacacia L.)改良的繁殖方法(英文)

在匈牙利,匈牙利刺槐(Robinia pseudoacacia L.)是重要的成林树种之一,且该树种的重要性在世界其它国家也日益增加。该树种的生产通常有两种方法:种子和根插条。组织培养对该种来说是一种相对较新的方法。对于在各种环境条件下大规模地生产苗木来说,种子栽培是相对简单的方法,机械化方法比较容易且生产成本相对较低。根插条和组织培养对于优势个体或品种繁殖是有价值的。利用这些方法,所选出的树木的优势品质可以在无性系得以保存。近期实验表明,微繁殖树木可以成功地移植到土壤中,在野外生长。

Propagation methods for black locust (Robinia pseudoacacia L.) improvement in Hungary

Black locust (Robinia pseudoacacia L.) is one of the most important stand-forming tree species in Hungary and its importance is increasing in many countries. Black locust plants are commonly produced by two methods, by seed and by root cuttings. Tissue culture propagation can be considered as a relatively new method. Growing trees from seed is a relatively sim-ple method for reliably producing seedlings on a large scale under a variety of circumstances. Mechanization of the method is easy and the production cost is relatively low. Propagation from root cuttings and tissue culture are valuable for reproduction of superior individuals or varieties. By applying these methods, superior traits of the selected trees can be preserved in the clones. Recent experiments demonstrated that micropropagated trees could be successfully transplanted into soil, hardened and grown in the field.
