Vigor de plântulas de Phaseolus vulgaris L. em diferentes potenciais osmóticos induzidos por polietileno Glicol-6000.

Abstract

Seeds of ten bean cultivars (Phaseolus vulgaris L.) were submitted to six levels of osmotic tension (0; -0,2; -0,4; -0,6; -0,8 e -1 MPa) of PEG-6000, with the purpose of studying the induced effects of water stress on the seedlings’ growth. The experiment was conducted in laboratory, in a germinator with controled temperature and humidity, making use of paper towel as a substract. The experimental design was completely randomized in a 10 x 6 factorial scheme with four replications each consisting of 10 seeds.
