Effect of fruits maturation stage and vegetal regulators in the physiological quality of seeds sweet passion fruit cv. BRS Mel do Cerrado

Abstract This study aimed to evaluate the effect of fruit maturation stages and pre-germination treatments with plant regulators on physiological quality seeds cv. BRS Mel do Cerrado. Two experiments were carried out, germination emergence, installed in a completely randomized design 3 x 2 factorial arrangement, three (1-partially ripe fruits; 2-fully fruits 3-senescent fruits) two (1. [GA4+7 +N-(phenylmethyl)-aminopurine (300 ppm)] 2. distilled water), forming six four replications 50 seeds. The evaluated characteristics percentage at 14 35 days, speed index (GSI), emergence (ESI). Germination GSI seedling not affected by stage, however higher when regulator was used. final taken from partially treated ESI observed for senescent regulator. Seeds are more vigorous have rate emergence.
