| 摘 要： | 为分析小麦赤霉病田间病情、病粒率与麦粒中脱氧雪腐镰刀菌烯醇(DON)含量的关系,以感染赤霉病不同病情的小麦样品为材料,用高效液相色谱法(HPLC)检测了麦粒中DON的含量。结果表明:麦粒中DON含量随田间病情级别或病粒率的提高而增加,呈极显著相关。依据病粒率推算DON含量,具有一定的实用性,但在小麦品种间以及不同病情条件下的理论值误差较大。 |

| Abstract: | In order to study the relationship between the wheat scab situation, rate of diseased grains and DON content, wheat samples contracted with wheat scab in different degrees were selected to determine DON content in grains by HPLC. The results showed that the DON content in wheat grains increased along with the increasing of field disease severity or the rate of diseased grains, which showed highly significant correlation. It was of certain practicality to calculate the DON content on the basis of the rate of diseased grains. But when it came to different wheat varieties and the disease severity, the theoretical value error was bigger. |
