Gibberellic Acid Concentrations and Storage of Caryocar brasiliense (Caryocaraceae) Seeds Propagated in Tubes

The immersion of seeds in gibberellic acid solutions can promote dormancy breaking. Storage be dynamic seed longevity. objective this work was to evaluate different concentrations applied isolated from two storage times on the emergence C. brasiliense tree seedlings grown tubes. There were experiments with planting and times. extracted endocarp. In both, a randomized block design used following seven treatments: 0, 50, 100, 500, 1000 2000 mg L−1 GA3 dry without pre-soaking, five replications 20 seeds. treated fungicide sown tubes containing substrate. After 60 days, evaluations transplantation carried out. experiment older pyrenes (seeds stored for months), there high mortality (96.54%) small rate (3.45%). On other hand, when new used, percentage dead 32.71% 62.28%. did not stimulate germination or diameter seedlings, except stem length. concentration provided greater length leaf area compared
