Abstract
Field experiment was conducted to investigate the effects of K supply on diurnal variations of net photosynthetic rate,transpiration rate,stomatal conductivity,intercellular CO2 concentration and water use efficiency in barley leaves at heading stage under enhanced UV-B radiation at the Station of Agricultural Meteorology,Nanjing University of Information Science and Technology,Nanjing,China.The experiment was designed with two UV-B radiation levels,i.e.ambient(CK,1.5 kJ/(m2·h)) and enhanced by 120%(1.8 kJ/(m2·h));and two K supply levels,i.e.73 kg K2O/hm2(low) and 150 kg K2O/ hm2(high).The results showed that enhanced UV-B radiation declined chlorophyll content,net photosynthetic rate,transpiration rate and stomatal conductivity in barley leaves,but had no obvious effect on intercellular CO2 concentration and water use efficiency.Increasing K supply could alleviate the damage of enhanced UV-B radiation to net photosynthetic rate from enhanced UV-B radiation,but not to transpiration rate and stomatal conductivity.
