摘要

本文报道了在番木瓜环斑病毒（ＰＲＶ）弱株系保护作用中，保护接种与攻击接种的浓度，以及攻击接种的部位等因素对ＨＡ＿（５－１）弱株系保护作用效果的影响结果。通过分析弱株系和强株系在保护接种后攻毒的植株体内的病毒浓度，表明ＨＡ＿（５－１）弱株系对Ｓｍ株系的保护作用的崩溃是由于强株系在植株顶端叶片中的病毒浓度越来越高所致。本义还就ＰＲＶ弱株系在田间的应用技术作了一些讨论。

Abstract

The present paper reported the effects of the ineeulum concentration of protecting strain and challenge strain,position of challange inoculation on the effectiveness of PRV mild strain cross-protection.Some technical aspocts in developing and implementing a cross protection program were suggestedbased on the exporimental results.Furthermore,it was found that the breakdown of cross-protection,asdefined by the appearance of symptoms caused by the severe strains,was related to the increase in virusconcentratio...
