研究了Penicilliumspp .引起的病害对贮藏过程中银杏种子的生理影响。结果表明 :病原菌接种 18d ,在 2 5℃ ,RH85 %的条件下 ,各组银杏种子表现出不同的病害症状。接种组种子的呼吸强度、失水率、膜透性较对照组分别增加了 1 2 7～ 2 96倍、 19 38～ 30 2 9倍和 1 0 6～2 75倍 ,三项指标上升的速度因病原菌而异 ,以P citrinum接种组最为迅速。此外 ,各接种组淀粉和蛋白质相对含量均高于对照组 ,但差异不显著。
The physiological effects of Penicilliumspp-induced diseases on ginkgo seeds during storage were studied. The results showed that under the conditions of 25 ℃ and RH85%, the ginkgo seeds of each group showed different disease symptoms on the 18th day after inoculation. The respiration rate, water loss rate and membrane permeability of seeds in inoculated group increased by 122-96%, 1938- 3029 and 106-675 times respectively than the control group, and the speed of three indexes increased Due to pathogenic bacteria, P citrinum vaccination group is the most rapid. In addition, the relative content of starch and protein in each inoculation group were higher than the control group, but the difference was not significant.
