Parthenocarpic fruits can be produced by
treating the plants with phenyl mercuric acetate.
treating the plants with gibberellic acid.
raising the plants from vernalized seeds.
None of these.
Spraying plant surface with phenyl mercuric acetate and silicon emulsion will result in
If a dwarf pea plant was treated with Gibberellic acid, it grows as tall as the pure tall plant. If the treated plant is crossed with a pure tall pea plant then the phenotypic ratio is likely to be:
