稀有植物矮杨梅种子繁殖试验

Propagation experiment of the seeds of rare plant Myrica nana Cheval

矮杨梅 (MyricananaCheval.)种子繁殖试验表明 :(1)当年收获种子基本无萌发能力 ;(2 )经低温 (4± 1℃ )层积或沙藏处理 8个月种子能萌发 ,前者发芽率低 (2 9.0 %) ,后者高 (6 7.5 %)。 (3) 6 0℃以上热水浸泡处理种子萌发率高 ;(4)种子在自然状态下不耐贮藏 ,经低温层积贮藏 2年的种子发芽率 (35 .4%)明显高于贮藏 3年种子 (8.2 %) ;(5 )矮杨梅是耐荫性植物 ,幼苗在遮荫条件下才能正常生长。

The propagation experiment of the seeds of Myrica nana Cheval was studied. The results showed that the seeds harvested in the same year rarely burgeon, which the seeds cumulated on 4±1℃ or preserved in sand after 8 months can burgeon with the budding rate of 29.0% and 67.5% respectively, and that soaking seeds using hot water (higher than 60℃) can improve burgeoning obviously. The results also showed that the seeds cannot preserve on the natural condition, but the budding rate of the seeds preserved 2 years is obviously higher than preserved 3 years cumulated on low temperature. Myrica nana Cheval is a kind of shade-resist plant, and the young plant only can grow on overshadow.
