Studies on the influence on germination of resting spores of Plasmodiophora brassicae on pakchoi

以两株对根肿病休眠孢子抑制作用较好的拮抗细菌为研究材料，对这两株拮抗细菌的发酵条件进行了研究。

Two strains of antagonistic bacteria were selected as the research material and the fermentation conditions of these two antagonistic bacterias were studied .

该菌休眠孢子在感病寄主的根分泌物溶液中萌发率最高，达75%。

The dormant spores of the fungus had the highest germination percentage ( 75 % ) in the root exudate of the susceptible host .

这说明硅藻休眠孢子的形成不仅受氮浓度的影响，还与硅浓度有关。

These results showed that the formation of diatom resting spores was related not only with N concentration , but also with Si concentration .

采用蔗糖密度梯度离心和超声波处理方法从油菜染病根部组织分离和提纯根肿休眠孢子。

The resting spores of P. brassicae were isolated and purified from infected root tissues of rape by density gradient centrifugation of sucrose and ultrasonic treatment .

比较了简化与不简化2种方法提取不同大麦品种根部所得的孢子数量，探讨了样品放置在超声波发生器上不同部位对休眠孢子提取效果的影响。

The efficiencies of spore extraction affected by sample positions in ultrasonic machine was examined and the procedure to extract the amount of spores from different barley varieties was compared with the original method .

度过5～6个月休眠期的冬孢子，必须浸水48h以上才开始复苏；

The spores spending 5-6 months of rest period , revived in water culture for more than 48 h.

首次对压载水及其沉积物中的休眠细胞&休眠孢子和孢囊的种类组成和丰度进行了调查研究。

The variation of resting cells - resting spores and cysts abundance in ballast water and sediment were first investigated .

由于压载水中的浮游植物可以将营养细胞转变为休眠细胞，压载水中的休眠孢子或孢囊通过压载水排入目的港，也会给目的港的生态系统带来潜在的危害。

A lot of phytoplanktons could survive by changing the vegetative cells into rest cells . Once these rest spores or cysts arrived destination with ballast water , might bring potential destroy to that area .
