Effects of copper on germination and reserve mobilization in Vicia sativa L. seeds.

摘要: Abstract The effects of different copper concentrations on percentage germination, increase in fresh weight and radicle growth Vicia sativa L. seeds were studied. Physiological studies showed that the germination rate was not affected up to a concentration 5 × 10−3 M, but already at 10−3 M stopped root elongation. Structural ultrastructural observations embryo cotyledon reserve mobilization inhibition Cu cannot be ascribed nutrient shortage probably an effect cell division In treated with 5 × 10−3 M CuBr2, completely inhibited protein mobilization, so supported normal 30 h after imbibition. particular content adjacent cells is also discussed.
