บทคัดย่อ (EN): Abiotic stresses like drought, temperature and light extremes cause production of reactive oxygen species through different mechanisms creating oxidative stress, which causes significant crop loss. Genetic engineering appears to be an alternative approach towards imparting stress tolerance in crop plants. One year old plants of MnSOD transgenic Havea lines (L1 and L2) and an untransformed line of clone RRII 105 were used in the present study to evaluate their physiological performance in a dry humid environment by withholding irrigation for six days and to see the recovery after re-watering for three days. The dry matter partitioning was relatively more towards the root in transgenic lines (55% and 60% in L1 and L2, respectively) more towards the untransformed RRII 105 (43%). After six days of moisture stress in polybags, pre-dawn leaf water potential and relative water content declined in all the lines, however, L1 showed higher tissue water content throughout the drought and following recovery periods. Chlorophyll content and effective quantum yield (OPISS) during drought period did not show a significant reduction. Net photosynthetic rate (PN) declined rapidly and by the 3rd day of drought treatment, reached near zero, barring L1, which showed slower decline in PN. The decline in stomatal conductance (gs) was more rapid than PN in all the lines. On re-watering, recovery in both PN and gs was better in the transgenic lines than enzymes namely, superoxide dismustase and peroxidase did not show any consistency in their activities in the three lines. SOD activity was higher in transgenic line L2 whereas the other lines had lower activity under well watered and drought conditions. Lipid peroxidation was more in the transgenic lines. The present study did not give a clear picture on the antioxidant enzyme activity and membrane in the transgenic lines. However, it was found that line L1 had better drought tolerant capacity under the drought conditions in the North Konkan region of India and the transgenic lines also showed better recovery upon new atering.
