Influence of the temperature on seed germination of Annona Montana

With the objective to evaluate the influence of the temperature in percentage of germination and the germination velocity index (GVI) of seeds of Annona montana, a potencial specie for a rootstock to the comercial varieties, were tested four temperatures (20, 25, 30 and 35ºC). The research was carried in conditions of laboratory, in chamber of germination type BOD using seeds of tree plants that came from the Germplasm Bank of the Department of Vegetable Production of the Faculdade de Ciências Agrárias e Veterinárias UNESP, Campus of Jaboticabal, São Paulo state, Brazil. The experimental delineation was entirely randomized, and four replications with ten seeds in each one. By the obtained results, was observed that to the parameter percentage of germination and for the GVI, the bigger values observed were for the seeds in temperature of 30ºC (55% of germination and GVI = 0,153), following by the temperature of 25ºC (25% of germination and GVI = 0,088). To the temperatures of 20 and 35ºC were not observed occurrence of germination. The statistical analysis of the values of percentage of germination were transformed in arc sen, square root (x/100) and the averages were compared by the test of Tukey, with 5% of probability.
