黄腊李是我区南丹县优良地方品种,也是中国李(Prunus salicina Lindl.)优良品种之一。具有高产、稳产、早熟、果实大、品质优良等优点。25～30年生树株产350～400斤,大小年不明显,五月底至六月初果实成熟,果皮黄色并有鲜红霞色,平均单果重56.2克,最大单果重75克,果实味甜汁多,可食部分达97％。据调查,目前优良株为数不多。因此,繁殖材料严重不足,种苗供不应求。为加快优选株的繁殖,在短期内能对开发山区资源有明显的经济效益,从1985年起,我们进行了黄腊李苗木嫁接和组织培养的试验,初步摸索出用三华李作中间砧木比单用毛桃作砧木效果好。用幼茎离体培养诱导腋生从芽已获得完整植株。现将初步试验结果报告如下:
HuangLaLi is a good local variety in Nandan County of our district and one of the fine varieties of Prunus salicina Lindl. With high yield, stable yield, precocious, large fruit, good quality and so on. 25 ~ 30 year-old trees produce 350 ~ 400 jin, the size of the year is not obvious, the end of May to early June mature fruit, yellow skin with bright red Xia, the average weight of 56.2 grams, the largest fruit weight 75 grams, sweet fruit juice , Edible part up to 97%. According to the survey, there are only a few excellent strains at present. Therefore, a serious shortage of breeding materials, seedlings in short supply. In order to speed up the propagation of the preferred strains, it has obvious economic benefits to the exploitation of mountainous resources in a short period of time. Since 1985, we carried out the experiment of grafting and tissue culture of the seedlings of Huanglu Li, It is more effective than using peaches as stock. In vitro induction of axillary with young stemlets Whole plants have been obtained from shoots. The preliminary test results are reported as follows:
