Doce cultivares y lineas de arroz (Oryza sativa L.) desarrollados por el programa fitomejoramiento del Instituto Investigaciones Agropecuarias (INIA), Centro Regional Investigacion Quilamapu, fueron caracterizados geneticamente mediante amplificacion fragmentos polimorficos (AFLP). De 21 combinaciones ensayadas, solo 16 informativas, generando un total 667 amplicones, 94 ellos (14,4%), con rango entre 9 33% polimorfismo combinacion. Esto indica que material manejado INIA presenta bajo nivel...

Nitrogen agronomic efficiency (NAE) is a key factor that has not been considered in rice breeding programs. The objective of this study was to evaluate nitrogen twenty genotypes an Acuic Durixererts soil (Quella Series) located Chile´s south central zone (36o04`S, 72o 0`W) over the 2008-09 growing season. field experiment carried out complete randomized split-plot block design with five N treatments 0, 50, 100, 150 and 200 kg ha -1 genotype sub-treatments. following characteristics crops...

As irrigation water decreases, crop transpiration also resulting in an increase leaf temperature and of the stress index (CWSI). Therefore, study, response Capsicum to different regimes was evaluated with periodic measurements temperature, stomatal conductance estimation CWSI. The treatments consisted a complete drip (RO) deficit (RD-78 RD-58) that received 78% 58% irrigation, applying total volume 3363, 2618 1956 m3 ha-1 for RO, RD-78 RD-58, respectively; obtaining maximum yields 30.2, 13.9...
