油菜开花期间,病菌子囊孢子能传播到花器官的各个部分,在脱落飘散的花器官中,花萼带菌的几率最高,有花瓣油菜花萼带菌平均为99.3％,雄蕊和花瓣次之,分别为92.0％和92.3％。无花瓣油菜花萼带菌也高于雄蕊。在花朵数相等的条件下,无花瓣品系花器官带菌几率的总和比四瓣油菜相对减少33.0～36.4％,平均为34.1％。与对照种相比,盛花后无花瓣品系的叶片间接受侵率明显低于对照种,成熟前植株间接受侵率相对减轻32.0～47.1％。植株间接受侵率(x)与病指(y)(y含直接和间接受侵)之间存在显著的正相关关系(r=0.6287),表明病情严重度随着植株间接受侵率提高而加重。
During the flowering period of rapeseed, aspergillus sporocysts could spread to various parts of floral organs, and the odors of carrying the sepals were the highest in the shedding flower organs. The average number of the edible aspergillus was 99.3%, followed by the stamens and petals, which were 92.0% And 92.3%. Petal rape Calyx carrier is also higher than the stamens. Under the condition of the same number of flowers, the sum of the organism-carrying probabilities of the flowerless organs was 33.0-36.4% less than that of the four-leaf rape, with an average of 34.1%. Compared with the control, the rate of indirect inter-leaf invasion of flowerless petals was significantly lower than that of the control, and the rate of indirect invasion of mature plants was reduced by 32.0-47.1%. There was a significant positive correlation (r = 0.6287) between indirect invasion rate (x) and disease index (y) (y with direct and indirect invasion), indicating that the severity of the disease increased with the indirect invasion of plants Increase.
