不断改良水稻的株叶型,使之在增大群体的条件下更好地利用光能,是高产育种的重要途径之一,迄今,人们在选育矮秆、叶片短、小、厚、直立等性状方面,作了大量工作,也取得了显著成效。选育卷叶性状以进一步提高光能利用率,可能是新的高产品种选育的突破口之一。叶片卷曲,有助于增强叶片的机械强度,进一步提高直立性能,减少遮光面,从而增大群体受光量,提高群体光合势,可能获得更高产量。 It is one of the important ways to improve the yield of rice by continuously improving the plant leaf type of rice so that it can make better use of light energy under the conditions of increasing population. So far, people are breeding dwarf, short, thick, erect And other traits, made a lot of work, but also achieved remarkable results. Breeding of curled leaf traits to further improve the utilization of light energy may be one of the breakthroughs in breeding new high-yielding varieties. Leaf curl, helps to enhance the mechanical strength of the leaves, to further improve the vertical performance, reduce the shading surface, thereby increasing the group by the amount of light to improve the population photosynthesis potential may be higher yield.
