马蹄金与匍茎翦股颖光合生理生态的比较研究

研究表明，１．通过光饱和点、光补偿点、ＣＯ＿２补偿点及叶绿素ａ／ｂ比值等测定，马蹄金与匍茎剪股颖均属喜光、耐荫的Ｃ＿３植物。马蹄金对强光适应性大于匍茎翦股颖。因而在芜湖地区作为大田草坪种植，则马蹄金优于匍茎葛股颖。２．ＮａＨＳＯ＿３均有增强光合速率、加速光合产物输出、增加于物质积累及提高生物产量的效应。光呼吸抑制剂在草坪生产上大有可为。

Comparative Studies on Physiological Ecology of Photosynthesis between Dichondra repens and agrostis stolonifera

The physiological regulation in the category of ecological study of photosynthesis between Dichondra repens and Agrostis stolonifera was carricd on by us for comparison. The experimental results indicated thatthe two plant species used for lawn purposes were all light loving and shade tolerant C3 plants. In contrast,behondra repens was more adapta ble to intense light than Agrforis stolomifera and the for mer would give someexpression to be more suitable for growth in Wuhu district.And moreover,it was shown by the authors thatNaHSO 4(a chemical reagent of photo respiratory inhibitor)increased the photosynthetic rate a nd biomass yi-eld,thus accumulating dry matter products and promoting yielding effect in the same way, somewhat beingbeneficial to the lawn construction.
