| This study evaluated mechanisms of the dehydration and rehydration of fruits and seeds on the resulting embryo viability of the macaw palm, Acrocomia aculeata (Jacq.) Loddiges ex Mart. Dehydration was performed in a forced-air oven at 37 ± 2°C for 0, 3, 6, 9, 12 or 15 days, and after these periods, the embryo viability was evaluated by the tetrazolium test. The effect of hydration on the germination percentage and velocity index was evaluated by the imbibition of seeds with distilled water in a germinator at 30 ± 2°C for 0, 2, 4, 6, 8 or 10 days. The seeds were then treated with fungicide and maintained in a Mangelsdorf germinator at 30 ± 2°C. Drying caused a progressive water loss in the fruits and facilitated the extraction of the seeds. Fruits subjected... |

| Jamun (Syzygium cumini L. Skeels) (Black plum, Damson plum) fruits weigh between 2-5 g at maturity. Fresh seeds represented 20-80% of the total fruit weight; the seed coat and cotyledons contributed 6% and 94% to the total seed weight respectively, while the weight of the embryonic axis was insignificant. Only the embryonic axis stained with Tetrazolium, not the cotyledons. The seeds are polyembryonic with up to four embryos, of which at most three germinate. Decoated seeds germinated faster than coated seeds under nursery conditions, with high significant germination percentages, dry matter production rates and vigor indices. The lack of staining of the cotyledon by tetrazolium was probably due to the presence of an impermeable layer. Decoating seeds for... |

| ABSTRACT The use of growth-promoting bacteria can increase the yield and quality of seeds of several annual crops, such as soybean. Based on that, the present study aimed to evaluate the effects of the inoculation of Bacillus subtilis strains on seed treatment, evaluating the yield and quality of seeds of two soybean cultivars. The experiment was conducted in a conventional system, in an Oxisol of clayey texture, in a crop under sprinkler irrigation. The experimental design was randomized blocks, arranged in split plots with four repetitions. Treatments were composed, in the plots, of two soybean cultivars: M7110 IPRO and Brasmax Desafio RR. Within the levels of subplots, the treatments consisted of inoculation and doses of inoculant: Bacillus subtilis... |
