桃花心木扦插快繁试验

Experiment on Rapid Propagation Technique of Swietenia mahagoni by Cuttings

摘要: 为提高桃花心木扦插育苗的成活率，开展了不同生根促进剂及浓度、扦插基质对桃花心木扦插育苗生根效果的影响试验。结果表明：用0.55 g·L⁻¹的IBA处理桃花心木插穗后，以红壤与珍珠岩1∶1混合为扦插基质，桃花心木的生根效果最好，生根率最高可达83.64%。

Abstract: In order to improve the cutting survival rate of Swietenia mahagoni, the experiments were carried out to study the effects of different rooting promoters, concentrations and cutting mediums on the rooting effect of cuttage seedlings of Swietenia mahagoni. The results showed that after the cuttage seedlings of Swietenia mahagoni were treated with 0.55g/L IBA, the highest rooting rate was 83.64% when the red soil and perlite were mixed at 1:1 as cutting medium.
