English Abstract

In this study we investigated the oxidative stress with different time in arugula leaves and response to different abiotic stress.

And see the effect of oxidative stress and response of plant .the chlorophyll a and b activity was significantly changed in response to drought stress in time dependent manner reached to 1.3X after six days of exposure in comparison to control.

Light quantity effect was showed that total chlorophyll a and b activity was light trigger since at all applied light quantities 10, 100 and 370μE with short term exposures (h) the activity increased in comparison to control.

While salinity effect started after long term exposure after at least six days of 100mM NaCl exposure.

The significant change in chlorophyll a and b activity in response to temperature treatment was degree dependent since at 4˚C was early response to maximum 4h.

While at 30˚C, the induction was also early response to maximum 4h.

These short terms exposure of temperature was not appeared after exposure to 35˚C.

Beside the change of chlorophyll a and b activity study, other measurements were included as hydrogen peroxide quantification, carotenoids contents, lipid peroxidation levels and protein contents.

Those responses were indicates that the plants have wide range of mechanisms to cope the different stresses and might be involvement of morphological changes.

The data we reported lead us to investigate and study the changes at the level of photosynthetic quantum yield, specific target metabolites and proteins and the level of non-enzymatic antioxidants.
