甜樱桃砧木品系对根癌病抗性的研究

A Study on the Resistance Strains of Sweet Cherry Rootstock to the Crown Gall Disease

通过10个甜樱桃砧木品系对根癌病抗性的调查比较,发现不同砧木品系抗性程度有明显差异,莱阳矮樱桃抗病性最高。接种试验证实发病时间早晚不同,但所有砧木均可感病。

The resistance of ten strains of sweet cherry rootstock to the crown gall disease was surveyed.The results showed that the susceptibility of different strains differed obviously.The resistance of short cherry of Laiyang was the highest. Inoculative experiments showed that ten strains of sweet cherry rootstock were all infected, but the time of being infected was different.
