A comparative study on chlorophyll content, chlorophyll fluorescence and diurnal course of leaf gas exchange of two ecotypes of banyan

Abstract

Abstract: The morphological differences,chlorophyll contents,fluorescence and diurnal course of leaf gas exchange between terrestrial banyan and amphibious banyan were compared with pot culture.The amphibious banyan possesses well developed aerial and hydro adventitious roots, and wider leaf with inclination of evolution toward mesophytic traits.The chlorophyll content of terrestrial banyan was higher than that of amphibious banyan.The diurnal course of leaf gas exchange indicated that net photosynthetic rate of terrestrial banyan was slightly higher than that of amphibious banyan grown in water,but much higher than that grown in soil.The amphibious banyan grown in water had the highest transpiration rate,the terrestrial banyan had a lower one, and the amphibious banyan grown in soil had the lowest.Linear regression analysis showed a positive correlation between net photosynthetic rate and stomatal conductance,implying that the stomatal conductance was dominant factor controlling the gas exchange.In this study,the term of intrinsic water use efficiency (net photosynthetic rate/stomatal conductance ratio,Intrinsic WUE) was applied to describe the photosynthesis and water properties, and the result showed that it was a more suitable measure compared to the usual WUE(net photosynthetic rate/transpiration rate).Among the three banyan plants examined,the amphibious banyan had the highest intrinsic WUE.

Key words: Banyan, Ecotype, Net photosynthetic rate, Stomatal conductance
