甜玉米异型杂交效应的研究

纯甜玉米虽然籽粒含糖分高，但因胚乳缺陷而使其出苗晚，出苗率低，幼苗生长弱，影响产量和经济效益。通过异型玉米花粉直感产生的饱满籽粒，可以提高出苗率，苗期长势好，提高产量和经济效益，且可改善甜玉米的品质。

A Study on Effects of the Different Genotype Hybrid in Sweet Maize

Sugar contents in the kernel of pure sweet maize is high. But,because of the defect of endosperm in kernel,the date of emergence of seedling is postponed,the rate of emergence is low,seedling growth is weak too.All these shortcomings can be overcomed by utilization of pollen immediate response between different genotypes of maize.In this condition,the kernel come into being plump,the rate of emergence is raised,the growth-impetusof seedling is fine,the field and ecnomic benifit increased,and the quality of sweet maize improved.
