玉米遗传改良的生理研究揭示了玉米杂交种的遗传增益可能归因于生物量生产的改(Tollenaar,1989,1991)。虽然目前使用的玉米栽培种增加的产量可能与光合速率和叶面积指数生理性状的改变有关(Dwyer等,1991),但是这些变化是通过常规育种方法间
Physiological studies of genetic improvement in maize revealed that the genetic gain of maize hybrids may be attributed to changes in biomass production (Tollenaar, 1989, 1991). Although the increased yield of currently used maize cultivars may be related to changes in photosynthetic rate and leaf area index physiological traits (Dwyer et al., 1991), these changes were made by conventional methods of breeding
