The recent research in the stress physiology of Hevea brasiliensis is reviewed focussing on two distinct, but adverse agroclimatic zones, namely the North Konkan and the Northe Eastern regions of India where the crop has been successfully cultivated. The North Konkan region experiences drought for about five to six months every year concomitant with high intensities of solar radiation and high temperatures, occasionally rising beyond the minimum temperature falling as low as 5 oC at least for brief periods in night, but the days can be relatively warmer with abundant sunlight. In both these unfavourable regions, with suitable agromanagement, polyclonal seedlings of Hevea establish reasonably well and with some added care, bud grafts of high yielding clones avlso could be grown. Stress induced inhibition in leaf photosynthesis was found to be a major cause for poor crop growth in studies conducted in both the regions. High light intensity concomitant with an environmental stress aggravated the stress induced inhibitory effects on photosynthesis. Photoinhibition of photosynthesis was evident in the quantum yields for carbon assimilation and Photosystem II activity. The CO2 saturated rate of photosynthesis and in vivo carboxylation efficiency of the leaf were inhibited during during drought and low temperature stresses. High intensity of solar radiation led to an imbalance between the light and dark reactions of phosynthesis in stressed Hevea leaves. This caused increased diversion of photosynthetic electrons for the production of active oxygen species which caused oxidative stress leading to senescence of the stressed leaves exposed to high light intensities. Therefore, partial shading to young plants experiencing stresses like drought and chilling is advisable. The Hevea germplasm pool may be a repository of inherent antioxidant and stress tolerance/avoidance traits which could be used in the crop improvement programmes for unfavourable agroclimatic regions.
