| 摘 要： | 为了明确硅对甘薯苗期黑斑病抗性的影响,以胜利百号(Triumph 100)薯苗为材料,用不同浓度的硅酸盐溶液预处理5 d后接种甘薯黑斑病菌,每24 h调查薯苗的发病情况.结果表明,硅能够延长甘薯黑斑病的潜伏期,显著降低发病率与病情指数,减轻其对薯苗的危害,提高甘薯苗期对黑斑病的抗性.

| Abstract: | In this study,triumph 100 seedlings were inoculated with Ceratocystis fimbriata at the fifth day after silicon treatment,and disease indexes were determined per 24 hours.The results showed that silicon treatment could prolong the incubation period of C.fimbriata and significantly decrease the incidence and disease index of sweet potato black rot.Therefore,silicon treatment could reduce the damage of black rot to sweet potato,and improve the disease resistance of sweet potato varieties. |
