title: Pre-packing cooling and types of packages in maintaining physiological quality of soybean seeds during storage

description: Abstract: Seeds storing under appropriate conditions reduces the speed of the seeds deterioration process. The aim of this study was to evaluate pre-packing cooling and types of packages in the maintenance of the physiological quality of soybean seeds during storage. The completely randomized experimental design was used, with four replications, considering a factorial arrangement involving or not the pre-packing cooling of the seed mass, three types of packages (multi-layer paper bag, big bag, and polyethylene container), and five storing periods (0, 2, 4, 6 and 8 months). The physiological quality was evaluated by the tests of first germination count, germination, accelerated aging, electrical conductivity, emergence speed index and emergence. The use of packages with larger amount of seeds (big bag and polyethylene container) did not favor the maintenance of the pre-packing cooling temperature. The types of packages did not show significant differences in the seeds viability during storage, up to eight months, regardless the pre-packing cooling. The cultivars seeds showed different tolerance to storing, i.e. seeds of the cultivar TMG 1176 had lower storing potential comparing to the seeds from the cultivar SYN 9074.

title: Morphological aspects of fruits, seeds, and seedlings, and anatomy of seedlings of apuleia molaris spruce ex benth

description: Abstract: Apuleia molaris spruce ex benth, commonly known in Brazil as "amarelão," is a fast-growing forest plant with a potential for use in reforestation; however, there is little information about the physiology and morphology of its fruits, seeds, and seedlings. Thus, the objective of this work was to describe the morphology of the fruits, seeds, and seedlings, in addition to the anatomic patterns of seedlings, as a contribution to the technical-scientific knowledge and production of amazonian species for reforestation in the state of Pará. For this purpose, the morphological descriptions followed the parameters from specialized literature and the common techniques used in plant anatomy. The species presents leguminous fruit; seeds with pleurogram, average dimensions of 51.21, 21.33, and 2.09 mm length, width, and thickness, respectively; and seedlings with eophyll and pinnate metaphylls, cordiform, phanerocotylar germination, epigaeous, and foliaceous. Eophylls and metaphylls present uniseriate epidermis, collateral and dorsiventral vascular bundle. The morphological characteristics may help in field identification and in the identification of young plants, aiding the production of seedlings of this species. Furthermore, anatomically, the hypocotyl has no striking differences from the root.

title: Biometry and germination of Balfourodendron riedelianum Eng. Eng.

description: Abstract This study investigated the biometry, pre-germination treatments and substrates for the germination of diaspores of Balfourodendron riedelianum. The diaspores were characterized during germination according to their length, width, thickness, thousand kernel weight (TKW) and water content. Dormancy overcoming was tested by diaspore scarifying with sandpaper, sulfuric acid immersion, water and water at 100 °C; together with the control (untreated), they were associated to different substrates (including paper (EP), sand (EA) and vermiculite (EV). Germination tests were conducted in a germination chamber at 25 °C. The physiological quality of seeds was performed through the first count, germination and germination speed index (GSI). Biometric data were analyzed in frequency classes and the pre-germination treatment by analysis of variance. Diaspores are on average 18.59 mm long; 9.03 mm wide and 9.38 mm thick. The treatment of immersion in cold water for 48 hours and the substrate vermiculite (EV) were effective to overcome dormancy and recommended for germination tests.

title: Morphological characterization of fruit, seed and seedling and germination of Hymenaea courbaril L. (Fabaceae) ('Jatobá')

description: Abstract This study has aimed to characterize the morphology of fruit, seed and seedling and evaluate the germination of Hymenaea courbaril L., under different substrates and temperatures. The physical characteristics were determined, as well as the morphological description of the internal and external parts of fruits and seeds, stages of germination and early seedling development. Germination tests were conducted in a completely randomized design, in a 3x2 factorial scheme, with three temperatures (20 °C, 25 °C and 30 °C) and two substrates (sand and vermiculite), with six plots of 30 seeds. The germination percentage, germination speed index (GSI) and mean germination time (MGT) were calculated. The fruits are dry and woody and the seeds are exalbuminous, with an axial embryo. The germination is epigeal and the seedling is phanerocotylar. The combination of vermiculite or sand associated to temperatures of 25 °C or 30 °C is effective for conducting the germination tests.

title: Exudate coloring test suitability for assessing the viability of coffee seeds ( Coffea arabica L.)

description: Abstract: The exudate coloring test has been promising in order to quickly evaluate the quality of coffee seeds. The objective of the research was to adjust the coloring exudate test for coffee seeds and to evaluate the influence of the water content of seeds and of the imbibition period on the test results. Seeds from five lots of 'Catuaí 44' were used, with the following water contents: 30%, 20% and 12%. For the exudate coloring test, the parchment and silver skin (spermoderm) from the seeds were removed. Then, the seeds were distributed on a paper towel, moistened with water, and kept in a germinator at 25 °C for 24, 48, 72, 96 and 120 h. Four classes of coloring intensity were established: absence of color (A), light (L), medium (M) and strong (S) intensities, assigning the values 0, 3, 5 and 10 for each class, respectively. The Viability Index (VI) was calculated by the equation VI=100-(0xA)-(3xL)-(5xM)-(10xS). The exudate coloring test may be recommended to estimate the viability of coffee seeds, providing results correlated to the germination test. The best results were obtained for the seeds with 12% moisture content imbibed for 72, 96 and 120 h and seeds with 30% moisture content after 72 and 120 h of imbibition.

title: Residual effect of bur gherkin seed treatment with biostimulant under salt stress

description: Abstract: The physiological quality of seeds used in agricultural production is one of the main factors that should be considered when implanting the culture. This study aimed at evaluating the quality of bur gherkin seeds, cv. Liso de Calcutá, coming from plants grown from seeds that were previously treated with biostimulant (0, 5, 10, 15 and 20 mL. kg-1 seeds) and cultivated in two irrigation water salinities (0.5 and 3.5 dS. m-1). Initially, the water content of seeds was determined and the following tests were performed: germination, accelerated aging, greenhouse emergence, emergence speed index, height and dry mass of seedling aerial part. It was found that the physiological quality of bur gherkin seeds coming from plants that were subjected to salt stress is negatively affected, and that the use of biostimulant, applied via seeds, provides beneficial effects on the physiological quality of seeds produced in the next generation.

title: Cell changes during the re-induction of desiccation tolerance in germinated seeds of Sesbania virgata (Cav.) Pers.

description: Abstract During germination, orthodox seeds lose their ability to tolerate desiccation resembling recalcitrant seeds. This research aimed to investigate the cell changes during the re-induction of the desiccation tolerance (DT) in Sesbania virgata germinated seeds with 1, 3 and 5 mm long radicles. To re-establish DT, germinated seeds were incubated for 72 h in polyethylene glycol (PEG, -2.04 MPa) before dehydration in silica gel (at 10% moisture content) followed by rehydration. Cell viability was assessed through TUNEL test in dry radicles and transmission electron microscopy in both fresh and dry radicles. The positive-TUNEL confirmed the DNA degradation, through the green fluorescence of the cell nuclei from 5 mm radicle length and the ultra structural evaluations detected loss of cellular content integrity in 3 and 5 mm cell radicles that did not survive dehydration to 10%.

title: Physiological potential of peanut seeds submitted to drying and storage

description: Abstract: This study was performed to evaluate the immediate and latent effects of drying air temperature on the physiological potential of peanuts (Arachis hypogaea L.). The fruits were harvested at the physiological maturity stage, with 36 ± 2% water content (w.b.), and dried at temperatures of 40, 50, 60 and 70 ºC, until 7 ± 1% (w.b.). Thereafter, the fruits were stored in an environment with non-controlled temperature and relative humidity for 150 days, and the water content, germination and vigor of seeds were immediately determined, as well as at every 30 days thereafter, through the first count, and the tetrazolium test, accelerated aging test, cold test with soil and electrical conductivity. According to the results, it was found that the physiological potential of peanut seeds is inversely related to the drying temperature and the storage time, due to the fact that the germination and vigor are reduced as both factors increase. The air temperature of 40 °C may be recommended for the drying of peanut seeds, and even associated with the storage time of 150 days under uncontrolled conditions.
