马铃薯早疫病

由茄链格孢菌（Alternariasolani）引起的马铃薯早疫病已成为危害马铃薯生产中严重的病害之一，对马铃薯的产量和品质影响很大。

The potato early blight , caused by Alternaria solani , has become one of the serious diseases in production and taken a great effect on potato yield and quality .

茄病交链孢霉（Alternariasolani）是番茄和马铃薯早疫病的致病菌。

Alternaria solani is a pathogen that causes the early blight of tomato and potato .

而马铃薯早疫病一直以来都是马铃薯生产上最重要的病害之一，近年来发生愈演愈烈，每年造成极大的产量损失。

But Early Blight has always been one of the most serious blight in production of Murphy , which becomes even more violent and results in a great yield loss these years .

采用经过IAA处理的离体叶片接种法，对16个马铃薯栽培品种的早疫病抗性进行了鉴定。

A total of 16 potato cultivars were tested for identification and evaluation of resistance to Alternaria solani by the detached leaflets inoculation with Indole Acetic Acid ( IAA ) treatment .

通过对抗性不同的马铃薯品种接种和未接种处理后进行生理生化指标的测定，研究马铃薯品种对早疫病的抗性机制。

The resistant mechanism of potato cultivars of early blight was studied through the determination of physiological and biochemical indicators of different resistance cultivars after inoculated and non-inoculated .
