Changes in chlorophyll, ribulose bisphosphate carboxylase-oxygenase, glycine betaine content, photosynthesis and transpiration in Amaranthus tricolor leaves during salt stress

摘要: SummaryWe examined changes in leaf growth and chemical composition, including chlorophyll content, ribulose bisphosphate carboxylase-oxygenase (RuBisCO), glycine betaine (GB) relation to photosynthesis transpiration responses salt stress Amaranthus tricolor leaves. To induce stress, plants were transferred a medium containing 300 mM NaCl for 7 d followed by of relief from salinity. A decrease enlargement began 3 after leaves subsequently showed the same degree regrowth as controls non-salt medium. Chlorophyll content expressed on leaf-area basis increased under conditions salinity due reduction tissue water content. The continued throughout RuBisCO soluble protein contents when dry-weight decreased response salinity, then gradually during period. GB slightly up ...
