Physiological quality of seed and seedling performance of crambe genotypes under water stress AGRIAMBI
Machado,Fernando H. B.; David,Andréia M. S. de S.; Cangussú,Lucas V. S.; Figueiredo,Josiane C.; Amaro,Hugo T. R..
ABSTRACT Water stress is a condition that causes physiological changes in different species and even genotypes of the same species. One of the osmotic agents most used to simulate this condition is polyethylene glycol 6000. The aim of this study was to evaluate the effects of water stress on the physiological quality of seeds and performance of seedlings of crambe genotypes. A completely randomized design was used, in a factorial scheme with two genotypes (one cultivar and one line) and five osmotic potentials simulated with aqueous solutions of polyethylene glycol 6000 (control = 0, -0.25, -0.50, -1.0, -1.50 MPa), with four replicates of 50 seeds per treatment. The effects of the treatments were evaluated by means of germination, first count, germination...
