摘要
树莓种苗繁殖方法一般采用根蘖分株、埋土压条和扦插。根蘖及压条分株繁殖方法受气候及环境条件影响,生育周期长,且苗木质量参差不齐,多年连续田间繁殖还易导致品种退化;扦插繁殖方法,各品种间扦插成活率差异较大,有的品种繁殖系数较低。植物组织培养具有生长周期短、繁殖系数高、遗传性一致等优点。如何利用树莓组织培养技术繁育种苗,以期应用此方法解决根蘖分株、埋土压条和扦插繁殖方法出现的问题。
Method of seedling propagation of raspberry is usually cultivated by root tiller,mound layering and cutting propagation.The propagation methods of root tiller and mound layering were influenced by climate and environmental conditions.So that the growth cycle was long,and the quality of seedlings was uneven.Field of seedling breeding easier lead to varieties of degradation in year by year.By cutting propagation method,the survival rate of cuttings was different among varieties,and which was limited by the number of mother plants,the propagation speed was slow.Tissue culture has the advantages of short growth cycle,high reproduction coefficient and consistent heredity.This paper describes how to use the technique of raspberry tissue culture to breed seedlings in order to solve the problems of root tiller,mound layering and cutting propagation.
