چکیده
Abstract The objective of this work was to evaluate the effects application glyphosate herbicide on seed reserve mobilization and seedling morphology genetically modified soybean. Two herbicide-tolerant (TMG 1264RR P98Y11) two herbicide-sensitive (Emgopa 315 UFUS 7415) cultivars were selected for study subjected germination, length, tests after treatments with solutions at concentrations 0.00, 0.06, 0.12%. hypocotyl/radicle ratio efficiency conversion reserves seedlings also determined. higher concentration glyphosate, lower percentage normal shorter mainly in cultivars. 'TMG 1264RR' glyphosate-tolerant genotype mobilized more efficient converting biomass into seedlings. Herbicide reduced average length caused roots become than hypocotyls. During changes since hypocotyl becomes proportionally larger radicle. Although, when applied, altered weight, four evaluated genotypes, most affected 'Emgopa 315' 'UFUS 7415', glyphosate-sensitive ones.

Effects of seed aging on subsequent seed reserve utilization and seedling growth in soybean
Reduced seedling growth is a consequence of seed deterioration. The heterotrophic seedling growth can be considered as the product of three components: (1) initial seed weight, (2) the fraction of seed reserves which are mobilized, and (3) the conversion efficiency of mobilized seed reserves to seedling tissues. It is not clear which of these component (s) is affected by seed deterioration. To ...
متن کاملSeed Germination and Reserve Mobilization
Germination incorporates events that commence with the uptake of water (imbibition) by the quiescent dry seed and terminates with the emergence of the embryonic axis, usually the radicle. It is a time of intensemetabolic activity, involving subcellular structural changes, respiration, macromolecular syntheses and, finally, cell elongation. Establishment of the seedling occurs following germinat...

متن کاملArborescent palm seed morphology and seedling distribution.
This study examines how the seed morphology of two large arborescent palms, Attalea maripa (Aubl.) Mart. and Astrocaryum aculeatum G. Mey, may affect their seed shadow in a seasonally dry Amazonian forest. In addition to being smaller and produced in larger numbers than those of A. aculeatum, A. maripa seeds also presented a substantially lower amount of nutritional reserves available for the e...
