苹果霉心病是元帅系统品种(如红星等)上一种重要果实病害。该病在幼果期能造成严重落果,采摘前,占落果总数的15—35％,个别年份高达50％以上;采摘后,果实贮藏初期,病果率在45％以上;贮藏后期,病果率增高,有的年份高达90％。 症状类型 1.整果腐烂:病部是从心室向果实表面扩展,有时中心果肉变空,整个病果呈现干缩状;心室中霉菌菌落呈桔红色,并杂有其它颜色的菌丝,多发生在生长前期。 2.心室腐烂:病部局限在心室部位,一般不向果肉扩展,但如果剖果诱发,仍能扩
Mildew heart disease is Marshal system varieties (such as red star, etc.) on an important fruit disease. The disease can cause severe fruit drop in young fruit, before picking, accounting for 15-35% of the total number of falling fruit, up to more than 50% in individual years; fruit picking rate is above 45% after picking; Higher rates, some as high as 90% of the year. Type of symptoms 1. Whole fruit decay: the diseased part is extended from the ventricle to the surface of the fruit, and sometimes the central pulp becomes empty, and the entire disease presents dry shrinkage. The mold colonies in the ventricles are orange-red and have other colors of mycelium, and more Occurs in the early growth stage. 2 ventricular decay: the disease is limited to the ventricular site, the general does not extend to the flesh, but if the dissection induced, still can expand
