盐胁迫对木槿属两个外来种质生长及叶绿素含量影响
Effects of NaCl stress on the growth and chlorophyll contents of two exotic germplasm of Hibiscus L.
摘要
Abstract
A pot experiment was conducted to study the effects of different NaCl stress levels on the growth and chlorophyll contents of Hibiscus ' Moy grande' and H. Dasycalyx. The height growth, shoot and root dry weight, root to shoot ratio and chlorophyll contents of the two species were investigated. The results showed that; no significant difference was found in the growth of the two species at 4 g/kg NaCl concentration, although the shoot and root dry weights declined remarkably in H. Dasycalyx(P < 0. 05 ) , yet values of the height were not significantly different in H. ' Moy grande' between control and 4 g/kg NaCl stress. Values of root to shoot ratio showed that effect of NaCl stress on shoot was greater than the root. The changing pattern of chl a and chl b contents was similar to the unit of mass of chlorophylls content. With the increasing of salt concentration, values of chl a and chl b increased in a certain extent. The results indicated that the NaCl stress resistance of H. ' Moy grande' was better than H. Dasycalyx's.关键词
