Abstract:
Taking the biennial pot of camphor hydroponics as test material,using 0,50,100,200 mmol/L 1∶1 of NaHCO3 and Na2CO3 mixture of processing camphora seedlings.Replace once 7 days of the nutrient soiytion and different concentration of NaHCO3 and Na2CO3,the saline-alkali tolerance of Cinnamomum camphora seedlings after 21 days were studied.The results showed that with the increase of saline-alkali stress,the content of chlorophyll a,chlorophyll b content,total chlorophyll content,carotenoid content; plant photosynthetic rate,stomatal conductance,transpiration rate,water useefficiency were decreased,intercellular CO2 concentration was increased.
