摘要
[目的]探究紫花杧果实生理病害海绵组织发生规律。[方法]于2002～2005年调查了紫花杧果实海绵组织病害症状,并综合分析了紫花杧果实生理病害海绵组织发病与其外部因素(果实成熟度、果实大小、单株结果量)的关系。[结果]病害症状主要特征是在果肉中部或中下部出现凹陷空腔,形成海绵状空洞。未成熟的果实基本不发病,果实临近成熟前10 d才开始出现病害。病害发生率与果实的单果重、果实纵横径呈极显著正相关。[结论]为该病田间诊断、鉴别以及采前和采后无损伤测试判断提供了借鉴。
[ Objective ] The aim was to study the occurrence regularity of fruit physiological disease spongy tissue in Zihua mango （Mangifera in- d/ca L. ）. [ Method ] Main features of disease symptoms of Mangifera indica L. were investigated from 2002 to 2005, and the correlation between the occurrence of fruit physiological disease spongy tissue in Marrgifera indica L. and external factors （fruit maturity ,fruit size and fruit yield per plant） was analyzed comprehensively. [ Result] The main features of disease symptoms appeared the dishing cavlty,the formation of sponge-like holes in the middle or lower part in ,the fruit. Immature fruits were basically not appeared the disease. The disease began to appear the fruit near maturity before 10 days. It was positive correlation between the disease incidence and fruit weight ,fruit vertical diameter or cross diameter. [ Con- clusion ] The research provides reference for field diagnoses,identification, preharvest and postharvest uninjurous test of fruit physiological disease spongy tissue,
