矮牵牛病毒病的初步研究

Primary Studies on Viral Diseases of Petunia

矮牵牛是一种草本花卉，主要用来布置花坛，但病毒侵染却严重地影响其观赏价值。国内外有关危害矮牵牛的病毒报道较多［１，２］，但较系统研究矮牵牛病毒病的报道较少，本文从矮牵牛病毒鉴定、优势病毒种类确定及防治矮牵牛病毒病进行了初步研究，现报道如下：材料与方法...

Two kinds of virus isolates P 14 and P a 1,P 33 were isolated from the mosaic,crinkled and stunted petunia (Petunia hybrida Vila) plants.The isolate P 14 was identified as cucumber mosaic virus (CMV) and the isolates P a 1 and P 33 as turnip mosaic virus (TuMV).CMV was the prevailing virus in petunia. Virus free research results showed as follows:(1)CMV free plantlets were not obtained when the leaves,flower buds and meristem tips (more than 0.3mm) were cultured; (2) CMV free plantlets were gained when 0.15-0.25 mm meristem tips from the infected plants or 0.3-0.5 mm meristem tips from the infected plants after different heat treatments were cultured.
