CONDICIONAMENTO FISIOLÓGICO DE SEMENTES DE PEPINO

Abstract

The current work had the objective to evaluate the effect of Hydropriming about the germination and emergence of seeds of cucumber, ordering improve the velocity and informing of this. The tests was conduced in the laboratory of Analysis of Seeds and Didactic Garden of Department of Plant Sciences of Universidade Federal Rural do Semi-Árido - UFERSA, in the period of September to October at 2009. For this, it was utilized seeds of cucumber cultivate Aodai, with four replications for next treatment (demonstration, Hydropriming and Hydropriming + drying). The seeds was hydroconditioned in towel-paper, in 20 ºC, until culminate 42,8% of humidity. Later were drying in ambient temperature of laboratory (28-30 ºC) and 45-55% of relative humidity, until hit moisture of 7,3%. The seeds was evaluated for tests of germination, velocity index of germination, first count of germination, aerial part length of seedling and aerial part dry matter mass. The statistical analysis was effectuated separately for next feature evaluated, determining the effects of treatments in completely randomized design, being the comparison of means out Tukey test in level of 1% of probability. Though the Hydropriming with or out drying promote benefit effects about the emergence of seedlings, aspect relationship of establish of stand, the technical needs of improvement for specie, given in necessity of adaptation of methodology of priming
