引起苹果霉心病的病原菌主要有两种,即链格孢和粉红单端孢。前者侵染引起的病果症状多局限于心室,生长期和贮藏期均可能发病,一般不影响食用价值。后者侵染引起的病果生长期多数症状不明显,贮藏期发病与温度、O_2、CO_2有关,温度是主要因子,呈正相关性。苹果入窖后40天,窖温在10℃左右或10℃以下,O_22％-4％,CO_210％-14％是有利于苹果贮藏而不利于苹果霉心病发病的环境条件。
Pathogenic bacteria causing apple mold heart disease are mainly two kinds, namely Alternaria and pink single-tipped spores. Symptoms caused by the former infection and more limited to the ventricular disease, growth and storage period may occur, generally does not affect the edible value. The infection of the latter caused by the disease fruit growth symptoms are not obvious, the incidence of storage and temperature, O_2, CO_2, temperature is the main factor, was positively correlated. 40 days after the apple cellar, cellar temperature at about 10 ℃ or below 10 ℃, O_22% -4%, CO_210% -14% is conducive to Apple storage is not conducive to the occurrence of mildew in apple environment conditions.
