鲜活食品的辐射保藏,国内外已进行了许多研究工作,有的已在生产上应用。但在苹果方面尚未见到借以明显提高贮藏效果的报导。红玉是优良的苹果品种,其果实在贮藏期间易发生红玉斑点病,且发病率很高。红玉斑点病是一种生理病害,其发病机理尚不清楚。 Radiation preservation of fresh food has carried out many research work both at home and abroad, and some have been applied in production. However, there has been no report on apples that markedly improves the storage effect. Red jade is an excellent apple variety, its fruit prone to ruby ​​spot disease during storage, and the incidence is high. Rhododendron disease is a physiological disease, the pathogenesis is not clear.
