Abstract

Germination was variable from one trial to another. Germination was lower in the deficient cultures especially in -P, -K and -S. The addition of more P greatly increased the per cent germination. Cultures un supplemented with all the major elements had germination percentage comparable with those cultures deficient in just one element. Morphologically, the embryos grown in complete and higher concentrations of the major elements had more and better developed leaf primordia compared to those grown in mineral-deficient media. The "shoot" length showed no statistically significant differences among the treatments. The number of emerged scale leaves did not exceed 3. Most remained in their first scale leaf condition. No root growth was ever observed.
