山西不同居群野生赖草光合特性研究
Evaluation of photosynthetic characteristics in different Leymus secalinus Populations in Shanxi
摘要
Abstract
Obj ective]In order to provide theoretical basis for reasonably selecting and utilizing the genetic resources of Leymus secalinus (Georgi)Tzvel,[Methods]eight populations of Leymus secalinus from Shanxi Province were cultivat-ed at Taigu of Shanxi,and Photosynthetic Characteristics were evaluated.[Results ]The results showed that net photosynthetic rate(Pn)of different populations was consistent with stomatal conductance(Gs)in different growth pe-riod.Shouzhou and Youyu populations had the highest net photosynthesis rate(Pn)and stomatal conductivity(Gs), but Hunyuan populations had the lowest.There were significant positive correlation between net photosynthesis rate (Pn),transpiration rate(Tr),and stomatal conductivity(Gs),were significant negative correlation with intercellular CO2 concentration(Ci).[Coclusion]Shouzhou and Youyu were the best,they could be used as a focus of breeding in the future.关键词
