香蕉日灼病是受高温烈日曝晒,新抽叶片局部组织的细胞被灼伤毁坏,而引起的一种生理性病害。香蕉受害叶片最初在嫩叶边缘开始出现浅黄色斑块,后逐渐变成浅褐色,最后斑块坏死和被腐生菌拓殖,加速了叶片干枯,减少光合作用面积,削弱植株生势,影响香蕉生长。果实受害时表面出现浅青黄色、不规则形的斑块,严重时表皮变木栓化,常引起爆裂,降低果品商用价值。每年5月开始发生,6～7月发生最
Banana Burn disease is exposed to high temperature sun, the new leaves of local tissue cells damaged by burns, which caused a physiological disease. Initially, the leaves of banana began to appear light yellow patches on the edges of young leaves, then gradually turned into light brown, finally necrosis of the patches and colonization by saprophytic bacteria accelerated leaf dryness, reduced photosynthetic area, impaired plant growth potential, and affected banana growth . Fruit damage when the surface appears pale yellow, irregularly shaped plaque, epidermis becomes clouded in severe cases, often causing a burst, reducing the commercial value of fruit. May each year began to occur, the most occurred in June to July
