玉米是对锌最敏感的作物之一,而玉米自交系生活力弱,危害更严重。缺锌时,叶片中叶绿体功能降低,叶绿素减少,叶片主脉两侧失绿,形成黄绿相间的条带,失绿部分叶片变薄,植株节间缩短。严重缺锌时,植株矮缩,根部变黑,叶片变短、变宽,叶肉变厚,比健株生长缓慢。若在玉米制种田中发生僵苗,则对种子质量产量影响很大。病害发生后,幼苗弱小,生长迟 Corn is one of the most sensitive zinc crops, while corn inbred lines have weak vitality and even more serious harm. When zinc deficiency, chloroplast function decreased and chlorophyll decreased, both sides of the leaf veins lost their green color, formed yellowish green and white bands, chlorophyll thinned leaves and internodes shortened. Severe zinc deficiency, the plant dwarf, darken roots, leaves shorter, wider, thicker than the leaf, growth slower than healthy plants. If the emergence of stiff seedlings in corn farming, the quality of the seed yield a great impact. After the disease occurs, seedlings are weak and grow late
