Abstract
Summary The effect of drought stress on wheat germ agglutinin (WGA) accumulation in the developing embryos of different wheat ( Triticum aestivum L.) cultivars was investigated. Although water potential of the grains was relatively less affected by water stress, a substantial increase in WGA accumulation was observed in response to drought, especially at 18 days post anthesis (DPA). After 30 DPA draughted embryos depicted degradation of WGA whereas embryos of irrigated plants maintained higher levels of WGA. Further, a likely role of WGA as scavenger of free radicals has been discussed.
