摘　　要：概括了杂交水稻早衰过程中光合系统、根系生理、叶绿素含量及一些酶类活性的变化,阐述了植物激素和植物生长调节剂与水稻早衰的关系,指出利用转基因技术向水稻基因组转入优良基因是培育抗早衰杂交水稻的新途径。The changes of photosynthetic system, root physiology, chlorophyll content and activities of some enzyme in process of premature senescence of hybrid rice were summarized,and the relationships of plant hormone and plant growth regulator with premature senescence of hybrid rice were described. Pointed out the new way of breeding anti-premature aging hybrid rice was to transfer valuable genes into its genome with transgenic technology was
