Abstract

To understand the mechanism of salt tolerance in Neolitsea sericea(sericeous newlitse), physiological and morphological expression studies were done. Water culture of sericeous newlitses one year old seedlings were conditioned by a stepwise increase in NaCl(from 0 to 9 gL- 1) added to the nutrient solution(Hiller)over 20 days respectively. The results showed that the proline, Na+ K+ and membrane permeability were increased,chlorophyll were decreased and the growth of stem and base diameter, the number of new shoots and roots were reduced. But the proline, conductivity and chlorophyll recovered lightly overtime.Analysisof variance showed that the one-year-old seedlingsgrowth in 9 gL- 1 NaClwere inhibited and significantly different(P 0.05)contracted with other treatments.Sericeous newlitse is a moderated salt tolerated tree species.[Ch, 5 fig. 21 ref.]
