title: Effects of copper on reserve mobilization in embryo of Phaseolus vulgaris L.
abstract: The present research reports a biochemical and micro-submicroscopic analysis of copper effect on reserve mobilization during germination of Phaseolus vulgaris L. var. soisson nain hatif seeds. Dry embryonic cells are rich in protein bodies and little starch grains. In Cu-treated embryos copper inhibited 50% of albumin and globulin mobilization after 72 h imbibition. The severe alterations in treated embryo cells, observed by electron microscope, were probably the cause of the inability to utilize the amino acids freed by protein mobilization and so possibly the cause of the inhibition of P. vulgaris embryonic axis elongation.
