油菜在不同生长发育期对病毒病的感病性是进行病害流行预测建立预测工具场的基础。油菜和十字花科蔬菜在苗期容易感染病毒病在五十年代以前就有研究报导,但其他生育期,特别是油菜开花期和角果发育期的感病性如何,尚末见到报导。为此进行了该项试验。

Rape and cruciferous vegetables are susceptible to virus disease at the seedling stage. Researches have been reported before the 1950s. However, there is still no report on the other growth stages, especially the susceptibility of the flowering and pod development stages of rapeseed. To do this test.
