Assessment of drought tolerance in few clones of natural rubber (Hevea brasiliensis) under dry hot climate of Odisha, India
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
A preliminary study was conducted to assess the drought tolerance at the early stages of growth in different clones of natural rubber (Hevea brasiliensis) at the Regional Research Station of Rubber Research Institute of India at Kadalipal, Dhenkanal, Odisha in eastern region of India. Poly bag plants of five clones RRII 430, RRII 105, RRIM 600, RRII 208 and IRCA 111 were assessed for the drought tolerance and compared drought injury indices status with same clones growing naturally in the adjoining field. Results of drought injury indicated scorching, leaf yellowing, drying and leaf fall at regular intervals, since imposition of drought stress conditions. Among various tested clones RRIM 600 and RRII 430 have comparatively higher drought tolerant. Plants under field condition showed drought injury symptoms much later than the poly bag plants. Drought indices, tolerance of drought of different clones and possible reasons have been also discussed.
