不同浓度氟对茶树幼苗光合作用的影响
Effect of Fluoride-stress on Photosynthesis of Tea Leaves
摘要
Abstract
Effect of Fluoride (F)-stress on photosynthetic gas exchange parameters was studied using 10-month-old clonalplantsofthetea,Camelliasinensis (L.)O.Kuntzecv.Ruixiang.Theplantsweregrowninpotsand fertilized with a nutrient solution containing 0 ,100 ,200 ,600 or 1 800 mg · L -1 F on a three times a week ,24-week application .The photosynthesis characteristics of the tea leaves were determined using a portable photosynthesis system (Li-6400) .The result showed that the tea leaves had increased CO2 assimilation ,stomatal conductance , transpiraition rate , intercellular CO2 concentration , and chlorophyll content when the F level was below 100 mg · L -1 .With the F concentration increased up to 600 mg · L -1 ,the CO2 assimilation ,stomatal conductance and transpiration rate decreased , but no differences in the intercellular CO2 concentration , water use efficiency or biomass .Symptoms of F-stress were apparent when the F concention was beyond 600 mg · L -1 (F content in the tea leaves was (2880 ± 220) mg · kg -1 .关键词
