In this study, the regulation of ascorbate peroxidase (APX) specific activity, anthocyanin, carotenoid, hydrogen peroxide, lipid peroxidation, and protein levels in cress leaves in response to different abiotic stresses were investigated. The total APX specific activity was significantly elevated after 9 days of drought treatment, short-term (2 h) exposure to 10, 100 and 370 µE of light, long-term exposure (at least 6 days) to 100 mM NaCl versus the specific APX activity in the controls. Furthermore, a significant change in total APX activity was detected in response to treatment with different temperatures; this change was an early response to 4 °C and 30 °C for a maximum of 4 h, while short-term exposure to 35 °C did not change total APX activity. The results of the present study revealed that plants have a wide range of mechanisms to cope with different stresses that possibly involve morphological changes. The result

Study curried out to evolution response growth and biochemical of Ocimum basilicum L. under drought conditions. Plant grown under treatment conditions (24 hours with-54 C, 21 C, 55-70% RH) and plant were transferred to growth chamber for 6 weeks. The results showed that the rate of increase in chlorophyll a and b was significant with an increase rate of 1.7 and 0.6 compared to control after three days of treatment. The results also showed that H2O2 content was increased and reached to 1.3, 2.8 and 3.5 X compared to the control after three, six and nine days of treatment respectively. One the other hand the levels of the enzyme APX activity, Lipid peroxidation and protein which was conducted on the tissue of basil leaves, increase compared with control after three days of treatmen
