| Research Abstract |
We examined the combined effects of salt, light and high temperature stresses on ascorbic acid(ASA, vitamin C) and antioxidant system of tomato fruits. Here we show that the effect of salt stress on ASA content and antioxidant system interacted with the other environmental stress such as light and high temperature, and these interactions were different between stress types. In addition, chlorophyll a fluorescence transient can be available to as a simple and quick stress indicator in response to salt and temperature stresses in tomato leaf and fruit. In conclusion, our results provide the basic information for improving the health-promoting properties of tomato by the combined effects of environmental stresses on antioxidant systems.
