In:
Drought resistance in crops with emphasis on rice p. 195-213Summary: Rice is cultured in environments that are hydrologically marginal for semiaquatic species. Evidence of the occurrence of adaptive mechanisms in the rice germplasm induced by drought stress is reviewed. Adaptive mechanisms of root and shoot systems are discussed in terms of selection pressure characteristics and resulting effects on crop water relationships, growth, and yield. The relevance of specific growth stages is illustrated and some interactions among adaptive mechanisms are discussed. Given the goal of agricultural productivity in contrast to natural selection an imaginative reassessment of the suitability of adaptive mechanisms for future breeding of rainfed rice cultivars is suggested.
