化学因素对马铃薯病毒钝化的研究

CHEMICAL FACTORS INACTIVATING VIRUS IN POTATO

通过出苗与田间试验检测，对１０种化学试剂在不同途径的使用，及对病毒的敏感性两方面，研究了化学因素对马铃薯病毒钝化的作用。结果表明，不同梯度的高锰酸钾、过氧化氢、新洁尔灭、尿素稀释液浸种，病毒钝化明显，发芽正常，出苗齐全，病毒再感染种类少，产量明显提高，且成本低，无公害，操作便捷，宜推广。

The effect of chemical factors on inactivating virus in potato was studied. Ten chemical re- agents were used in different ways. The results showed that when seed potatoes were soaked in potassium per- manganate and hydrogen peroxide solution, in bromogeraminum solution of different gradients and in dilute urea solution, the viruses wre obviousely inactivated; the treated poatoes normally sprouted, uniformly emerged, secondery infection reduced and yield apparently increased. These messures also have the merits of low cost, no environmental pollutinon and easy operation. They are worthy to be used in potato production.
