干旱胁迫对甘蔗品种及野生近缘材料光合特性及水分利用率的影响
The Effects of Photosynthetic Characters and Water Use Efficiency under Drought Stress in Sugarcane Materials
摘要
Abstract
The photosynthetic characters and water use efficiency were measured under drought stress with six sugarcane materials planted in pots. The results showed that net photosynthetic rate, transpiration rate and stomatal conductance all decreased, but intercellular CO2 concentration and water use efficiency had different change tendency with the increasing of drought stress time. There was higher correlation among photosynthetic traits in different sugarcane materials. ROC22 and S. spontaneum L. performed to be highly resistant to drought. Fruit Sugarcane and KN90-445 performed middle resistance. S. robustum Brandes et Jeswiet ex Grassl and ROC 16 performed to be poor resistant to drought.关键词
