Abstract:
Drought is one of main abiotic stresses limiting wheat production. In this paper, we investigated the feasibility of using zinc fertilizer to alleviate the impact of drought on growth and yield of the wheat. The cultivar Yunong211 was used as the model plant, and the effect of zinc fertilizer on SPAD value, leaf water content, dry matter accumulation, filling rate, accumulation of zinc in grain, as well as the yield was examined under different drought stresses. The results showed that drought significantly reduced the chlorophyll content in leaves, leaf water content, dry matter accumulation, filling rate, accumulation of zinc in grain and the yield. Applying adequate zinc fertilizer improved the chlorophyll content in the leaves, total plant dry matter, grain filling rate, zinc accumulation in grain, and yield. In our experiments, applying zinc fertilizer increased yield and zinc content in the grain by 4.80% and 36.86%, respectively, when the plant was subjected to drought stress.
Key words:  zinc; drought stress; winter wheat; grain zinc accumulation; yield
