本实验测定了卫星病毒CMV—S_(52)对多种蔬菜的安全性。测定的范围包括7科16种21个品种的蔬菜。结果证明S_(52)对这些蔬菜作物是很安全的,自接种后连续观察20天均不表现任何症状。一、试验目的卫星病毒CMV—S_(52)是往CMV中加入了卫星核酸制成的,经室内及田间的大量试验证实:对CMV强株系具有较强的保护作用。因此,它有希望成为防治甜椒病毒病的综合防治措施之一。但对其应用到田间,也还存在(1)稳定性问题,即CMV—S_(52)应用到田间后会会不会变为强株系;(2)由于植物病毒寄主范围相当广泛,在一些植物上表现轻微症状,
This experiment measured the satellite virus CMV-S_ (52) on a variety of vegetables safety. The measurement range includes seventeen vegetables, 21 species and 21 varieties. The results showed that S_ (52) was safe for these vegetable crops and did not show any symptoms for 20 consecutive days after inoculation. First, the purpose of the experiment The satellite virus CMV-S_ (52) is added to the CMV satellite nucleic acid made by a large number of indoor and field tests confirmed: Strong strains of CMV has a strong protective effect. Therefore, it is hoped that it will become one of the comprehensive prevention and control measures of pepper virus disease. However, its application to the field, there are still (1) the stability of the problem, that CMV-S_ (52) applied to the field will not become strong strains; (2) due to a wide range of plant virus host, Some plants show mild symptoms,
