摘 要：
以菟丝子(Cuscuta australis)为媒介,将泡桐丛枝病(Paulownia witches broom)类菌原体(Mycoplasma—like organisms,MLO)接种至长春花上(Vinca rosea),对感病长春花施用激动素(Kinetin)后,结果表明,叶片韧皮部MLO显著减少,叶绿体形态结构正常,没有出现病株所出现的空腔;叶绿素和类葫罗卜素合成量是未施激动素病株的6.8倍和7.3倍;核酸合成量也显著增多。

摘 要：
The infected periwinkle plants were obtained by inoculating with the mycoplasma-like organism associated with paulownia witches broom from paulownia by dodder, and some of them were treated with kinetin(0.05mg/ml)for 20 days. The biochemical eff(?) of the kinetin on the infected plants were reported. The preliminary results revealed that, aft(?) the treatemnt, a great recovery on the morphological structures of the chioroplasts were ob(?) and the concentrations of the chlorophyll and carotenoid were increased by 6.8 timecs and 7.3 times respectively compared with that of the untreated periwinkle. The PWB-MLO show(?) teriorating trend. At the same time, kinetin also had a positive effect on the synthesis of (?) nucleic acids.
