Plant growth regulators in the germination of Diospyros hispida A. DC. (EBENACEAE) seeds

Plant growth regulators in the germination of Diospyros hispida A. DC. (Ebenaceae) Seed. species is a native fruit that has long period, hindering seedling production. The aim this work was to evaluate seeds under effect gibberellic acid and biostimulant applications. Four replicates 25 per treatment were used. Treatments were: T1 - distilled water, T2, T3 T4 GA3 solutions at 100, 150 200 mg L-1, respectively, T5 Immersion for 24 hours water with aeration, T6, T7 T8 aerated T9, T10 T11 application (containing auxin, gibberellin cytokinin) 3, 5 7 ml kg-1 seeds. Germination rate, mean time, speed index, synchronization relative frequency, normal seedlings, root length, shoot length dry mass evaluated. containing cytokinin negatively influenced conditions study.
