Effect of salt stress on acid phosphatase activity and phosphorus content of Lycopersicon peruvianum L. under in vitro culture
In this study, the effect of different concentrations of NaCl (0, 60, 90, 120 and 150 mM NaCl) on phosphorus content and acid phosphatase (APase) activity in Lycopersicon peruvianum L were investigated. Results indicated that phosphorus content was decreased and Apase activity was increased at 150...

| Summary: | In this study, the effect of different concentrations of NaCl (0, 60, 90, 120 and 150 mM NaCl) on phosphorus content and
acid phosphatase (APase) activity in Lycopersicon peruvianum L were investigated. Results indicated that phosphorus
content was decreased and Apase activity was increased at 150 mM NaCl. With increasing salinity levels phosphorus
content of roots decreased in all NaCl concentrations, but the Apase activity increased significantly with increasing salt
concentrations. Salt stress did not change the relative chlorophyll content of leaves. It can be concluded that salt stress may
induce APase activity accompanied by a low level of Pi. |
