沉水樟高龄植株扦插繁殖的初步研究

对沉水樟高龄植株 (16年生 )的插穗基部处理方式、生根促进剂、ABT生根粉处理效果、扦插基质等方面作初步探讨。结果表明 :沉水樟的插穗基部以双削处理的成活率高 ;1%H2 O2 、0 0 5 %KMnO4 、5 0× 10 -6IAA、5 0× 10 -6NAA处理插穗 ,均有利于促进沉水樟的生根成活 ,其中 1%H2 O2 处理效果最好 ;4种ABT的 8种处理沉水樟插穗 ,以 15 0× 10 -6ABT1#效果最好 ;利用河沙和蛭石两种插壤 ,河沙的扦插成活率明显高于蛭石

A Preliminary Study on Cutting Propagation Techniques for Old Plants of Cinnamomum micranthum

The results show that the survival rate of the treatment for cutting two sides of the base of Cinnamomum micranthum cuttings is high;the rooting of the cuttings can be promoted with 1% of H 2O 2,0.05% of KMnO 4,50×10 -6 IAA and 50×10 -6 NAA to treat them,among which 1% of H 2O 2 treatment effect is best;by using 4 kinds of ABT to conduct 8 treatments for the cuttings,150×10 -6 ABT1 # effect is optimal;and the survival rate of cuttings in sand is much higher than that in vermiculite.
