TOLERÂNCIA DA JITIRANA A DIFERENTES NÍVEIS DE SALINIDADE DURANTE A GERMINAÇÃO E DESENVOLVIMENTO DE PLÂNTULA

Abstract

This assay was conducted at the Departamento Ciências Vegetais of Universidade Federal Rural do Semi-Árido, with the objective to evaluate the tolerance of the jitirana (aegyptia Merremia L.), in saline solution. The used experimental delineation was the inteiramento casualizado with four treatments and four repetitions. The treatments had evidenced of four levels of salinity: testemunha (0,614ds/m) and the three saline solutions the 10, 20 and 30ds/m. The seeds had been incubadas in the sand esterilizada in caixotes wooden with capacity of 100 sementes.O parameter germination percentage were used as identification character of resistance. Ahead of the displayed one one concludes that the jitirana is tolerant the salinity since the same dS/m came to present reduction in the germination only in the C.E=30.
