摘要

摘要：应用RT-PCR一法拉测了PRSV Ys株系在感病番木瓜及其抗病突变体植株体内的运转动态结果表明：在感病植株中，接种后48h r按种叶的未接种部位可检出病毒，第4天部分接种叶柄可检出病毒，第6天植株各部位均能检出荷毒；而在抗病植株 ft，接种后可以而且仅脂在接种部位检出病毒；因而认为抗病突变体能够阻碍病毒从接种部位运出及(或)向米接~t,gt5位运入。

Abstract

One—step RT—PCR was used to detect papaya ringspot virus(PRSV)movement in susceptible and resistant(mutant)papaya(Carla papaya L )plants．The time of post—inoculation at which PRSV Wc-lS first detected in susceptible plants was 48 hours in the other area of inoculated leaves OUt Of inoculated sites．4 days in the petioles of inoculated leaf and 6 days in all parts of plant．Compa rative— ly，in resistant plants，the inoculated sites were the only area at which PRSV can be detected any time．Therefore．it was proposed that the mutated resistance to PRSV protects the virus from moving out of inoculated sites or／and into non- noculated areas．
