Abstract

The artificial wetland system is an integrate ecosystem, with well interior cycles and better economic benefit and ecological benefit. Daily variation in stomatal conductance of wetland plant were studied in this paper.The results showed that daily variation in stomatal conductance of leaf has the tendency of double-peak curve, appearing "noon break" in clear day, and peak value in the morning is higher than that in the afternoon. This is not influenced by temperature of leaf, relative humid, air temperature and flux of light quantum, but controlled by comprehensive impact of environmental factors and physiological characteristics of Alisma orientate. The author thinks that the different response of wetland plants to environment can provide theory basis for the construction of biodiversity of constructed wetland garden.

Key words： Alisma orientate Stomatal conductance Daily variation Environmental response
