Leaf Water Relationships and Canopy Temperature as Criteria to Distinguish Maize Hybrids under Drought Stress
This research aimed at studying the physiologic traits of maize different hybrids and considering them as screening criteria to select the drought tolerant hybrids. The experiment was conducted using a randomized complete block design with three replications and in a split-plot arrangement. The trea...

The treatments were as follows: Maize Hybrids (including SC400, ZP434, SC524, ZP599, BC66, SC704) and irrigation regimes (including optimum; 100% FC, moderate; 75% FC, and severe stress; 50% FC).
