Abstract

A greenhouse experiment was carried out to assess the reaction of five maize (Zea mays L.) genotypes under drought stress. Seeds were planted in Petri dishes. The study was established in a completely randomized design with five replications. The plants were harvested 15 days after sowing, and leaf area per plant (LA), longest root length (LRL), plant height (PH), root fresh weight (RFW), root dry weight (RDW), shoot dry weight (SDW), RDW/SDW ratio, and total dry matter (TDM) were determined. Significant varietal differences for all characters were found. The data obtained allowed to identify SC 500 as a suitable genotype at low water supply.

 

Key words: Zea mays, leaf area, root length, plant height, root weight, shoot weight, total dry matter, poly ethylene glycol.
