| Se caracterizaron nueve materiales genéticos de maíz (Arichuna, Baraure, Braquítico, Experimental-2, Foremaíz PB, FM-6, Obregón, Proscca-71 y Tocorón), en relación con área promedio de hoja por planta, área foliar total por planta (AFT), índice de área foliar (IAF), y coeficiente de extinción de luz (K) a 0,50 m, 1,00 m, 1,50 m, 2,00 m y 2,50 m de altura de la planta (medidos a partir del suelo). Además, estudios de correlación y regresión simple fueron hechos entre rendimiento (R) y IAF. Se encontraron rangos de variación para las diversas variables: Area promedio de hoja por planta(471cm² para Foremaiz PB y 606 cm² para Baraure); AFT ( 5 327cm² en Foremaiz PB y 8 411 cm² para Braquítico); IAF (4,26, Foremaiz PB y 6,67, Braquítico); K (0,23 para... |

| A greenhouse experiment was carried out to evaluate the responses among 10 maize (Zea mays L.) genotypes under drought stress. Seeds were planted in washed sand in plastic pots. The research was established in a completely random design with ten treatments and three replicate pots. The plants were harvested four weeks after sowning, and leaf area per plant (LA), root volume (RV), longest root length (LRL), plant height (PH), fresh (RFW) and dry weight (ROW) of roots, shoot dry weight (SOW), RDW/SDW ratio, and total dry matter production (TDM) were determined. Significant varietal differences for all characters were found, except for LRL. The data obtained allowed to identify Cargill-163 as a poor genotype at low water supply. Danac-3006, FM-6,... |
