Abstract
A field experiment was conducted to investigate effects of enhanced ultraviolet-B(UV-B) radiation on physiological characteristics,e.g.photosynthesis and transpiration,of different cultivars of barley.The experiment was designed to have two levels of UV-B radiation,i.e.enhanced UV-B(14.4 kJ·m-2·d-1) and ambient UV-B,and conducted at the Agro-Meteorological Station,Nanjing University of Information Science and Technology,Jiangsu Province,China.Results show that enhanced UV-B obviously depressed photosynthesis and transpiration in all the barley cultivars.Compared with control,enhanced UV-B radiation significantly decreased chlorophyll content,stomatic conductance,net photosynthetic rate and transpiration rate,but generally had no effect on intercullular CO2 concentration in the leaves of the plants.However,the plants varied in sensitivity to UV-B radiation from cultivar to cultivar.Cultivar Dan #2 was more sensitive than Cultivar Su #4.
