微量元素硼对小麦生长发育及碳水化合物代谢的影响

春小麦赛洛斯用适宜浓度的认浸种和各期根外追肥的方法处理后,皆可促进小麦幼苗根系的生长发育;促进生长锥的分化和器官的形成过程;可提高主茎旗叶面积和花粉生活力;可促进小麦叶部和生殖器官糖类的合成和叶内由光合作用制造出的糖类向生殖器官的运转;春小麦赛洛斯用硼进行根外追肥的时期,从孕穗－开花期喷射效果最显;用硼进行播种前处理和根外喷射,皆能提高小麦产量。

THE EFFECTS OF TRACE ELEMENT BORON ON THE GROWTH AND DEVELOPMENT AND METABO -LISM OF CARBOHYDRATE IN WHEAT

Soaking seeds in boric acid solution with right consistency and dressing foliage in various stages can promote the growth and development of the root system of wheat seedlings, and can also promote the differentiation of the growing cones and the forming process of organs;meanwhile, the flag-leaves area of main stems can be enlarged, and the viability of pollen can be improved by doing so. Boron can accelerate the synthesization of carbohydrate in leaves and reproductive organs of the wheat, it can also accelerate the transportation of the carbohydrate caused by photosynthesis in leaves to reproductive organs.
