滇丁香繁殖技术研究

Advances on Researches Cultivation of Luculia pinceana

本文报道了滇丁香繁殖试验结果。1.种子繁殖于3月上旬以湿沙为基质播种,可获得80—90%的发芽率;2.种子保存以风干低温瓶装贮藏为好,保存一年后种子萌发率仍可达77.5%以上;3.种子萌发最适温度为18—250C,此时发芽率达91%以上;4.扦插繁殖于7—8月份采顶部枝条作插穗,以湿沙为基质,成活率仅为33.33%,但如以IAA处理,成活率可提高到80%以上。

The result of the Luculia pinceana reproduction test has been reported in this article. 1. take the wet sand as the matrix, the germination percentage of seed may obtain 80-90% ; 2. the seed is air - dry and bottled of the low temperature the seed sprouting rate can reach above 77.5% after preserved for a year; 3. germination rate reaches above 91% in 18-20℃, which is the optimum temperature of the seed sprouting; 4. picking a crown and inserting it to wet sand, the survival rate of the division reproduces is only 33.33%, but make it by the IAA processing, the survival rate may enhance to above 80%.
