多叶玉米美国的科研人员最近培育出一种在果穗上生长大量叶面的玉米新品种。这种玉米的叶面积比普通杂交玉米大一倍多,被称为超多叶玉米。该种玉米受光足,产生的营养物质大部分都能转移到发育中的果穗中去,因此,它果穗长,籽粒行数多,灌浆足,产量比对照品种高60%。 Leafy corn US researchers have recently developed a new variety of corn that grows large numbers of leaves on ears. This corn leaf area more than twice as common hybrid corn, known as super-leafy corn. The corn is light enough to produce most of the nutrients can be transferred to the development of the ear to go, so it ear length, grain rows and more, enough filling, yield 60% higher than the control varieties.
