Influence of chlormequat chloride on photosynthesis and nitrate assimilation in wheat genotypes under water stress

The present experiment was conducted to study the effect of chlormequat chloride (CCC) on two drough tolerant (C 306 and Pissi local) and two drought susceptible (WL 711 and WH 147) wheat genotypes under moisture stress. Results showed an increase in leaf water potential, nitrate reductase activity, photosynthesis and chlorophyll content in the leaf by CCC foliar application under moisture stress condition at tillering and anthesis stages. There was also a concurrent increase in grain yield. The effect of CCC was more pronounced in drought tolerant genotypes compared to susceptible ones.
