Abstract

The leaf chlorophyll contents, the daily dynamic of net photosynthetic rate (Pn), stomatal conductance (Gs), intercellular CO2 concentration (Ci) and major affecting factors were determined of three clones of Catalpa bungei under salt stress.The results showed that Chla, Chlb and Chlt contents decreased under salt stress and significant differences were found of Chla, Chlb and Chlt among 3 clones of C. bungei.The ratios of Chla/Chlb increased with the increasing of salt concentration, and significant differences were found in different treatments of 02-2-5 and 07-1.The maximum of Pn (Pmax) appeared at 8:00 in all treatments of 3 clones, with the sequence of 02-2-5>YQ1>07-1,and significant differences were found in 3 clones.Pn was also decreased with the increasing of salt concentration, and the sequence of decrement was 07-1>YQ1>02-2-5.Stepwise multiple-regression and path coefficient analysis indicated that the major affecting factor of Pn were Ci, leaf temperature (Tl) and photosynthetic active radiation (PAR) in clones of 02-2-5 and YQ1, but Gs and Ci in 07-1.Based on the variations of leaf chlorophyll contents and Pn among 3 clones under salt stress, 02-2-5 had the highest salt tolerance, followed by YQ1, and 07-1.
