【摘要】 研究了影响菜豆普通花叶病毒(BCMV)种子传毒的一些因素,不同品种,不同感染时期种子的传毒率有显著差异,苗期感病的植株,不同荚位的种子传毒率是:下部>中部>上部,花期感病者则是:中部>上部>下部,感病植株的斑驳荚种子传毒率,依品种的不同,比无斑驳荚者高3.2～9.3倍。更多还原

【Abstract】 The percentage of seed transmission varied significantly with the culti-vars and the age of plants inoculated. Different pod sets infected showed the seed tra nsmissicn percentage in the following order : Lower>middle> upper when plants were inoculated during seedling stage, middle>upper>lower when inoculated during flower. The percentage infection of mottle pods was 3.2-9.3 times higher than that of nonmottled of the same plant.更多还原
