ABSTRACT:
Methods and compositions are provided to improve the quantity of embryos obtained by induction of somatic plant tissue. These involve the addition of effective amounts of selected amino acids, their derivatives or combinations of these as a source of reduced nitrogen, together with an optimum auxin dosage to the nutritive media used to regenerate or maintain the embryonic tissue. A synergistic effect is found by adding these amino acids either in combination or in combination with ammonium ion together with the selected auxin dosage.
