对除乐昌含笑以外的4个树种进行了7种脂肪酸成分即肉豆蔻酸、棕榈酸、棕榈油酸、硬脂酸、油酸、亚油酸、α亚麻酸的测定。

The components of fatty acids were myristic acid , palmitic acid , palmitoleic acid , stearic acid , oleic acid , linolic acid and α - linolenic acid .

分别对乐昌含笑进行不同年龄母株、不同比例生根粉、不同扦插季节进行扦插试验研究，结果表明：母株的起始年龄2～3年生的比7～10年生的插穗生根率提高18.5%；

Experiment on propagation techniques of Michelia tsoi with different aged parent tree , different percentage of ABT in different cutting seasons resulted rooting rate of cuttings from 2-3 years parent tree was 18.5 % higher than that from 7-10 years .
