灰桉(Eucalyptus cinerea)引种栽培的初步研究

Preliminary study on introduction and cultivation of Eucalyptus cinerea

本文对对引自澳洲的植物灰桉(Eucalyptus cinerea)进行了初步试验。结果表明,冬季40℃水浸种处理发芽率为最高31.6%。苗期生长需要充足的水分,而喜光性却是从苗期就开始显现。以带腋芽的茎段作外植体进行培养,在适宜的培养基上培养时不定芽的增殖可达1.4倍。

The introduction and vegetative propagation of Eucalyptus cinerea were studied in this experiment. The result showed that the greatest germination rate of seed was 31.6% after the seed had soaked at 40℃ in winter. On the basis of applying sufficient amount of water can improve the quality of seedings, the light-loving of this plant was oberverd since seeding stage, the seedlings grew better in full sun. The reproduction of adventitious buds could reach 1.4 times on suitable cultrue medium when the tender stem-segments with auxiliary buds were cultured as the explant.
