上海市郊春番茄病毒病检测结果表明,其毒原种群主要是TMV(烟草花叶病毒)、CMV(黄瓜花叶病毒)。1987年首次检出还有PVY(马铃薯Y病毒)和PVX(马铃薯X病毒)。PVY为害番茄较TMV或CMV轻,但往往与TMV或CMV混合浸染番茄,植株明显黄化矮缩,甚至使果实僵化,失去经济价值。
The test results of the tomato virus disease in the suburbs of Shanghai show that the virulent population is mainly TMV (Tobacco mosaic virus) and CMV (cucumber mosaic virus). The first PVY (potato virus Y) and PVX (potato X virus) were also detected in 1987. Tomatoes with PVY were lighter than those with TMV or CMV but were often contaminated with TMV or CMV. The plants were obviously yellowed and dwarfed, and even the fruit became rigid with loss of economic value.
