Gibberellins are another kind of promotory PGR. There are more than 100 gibberellins reported from widely different organisms such as fungi and higher plants. All GAs are acidic. They produce a wide range of physiological responses in the plants.

A dwarf pea plant was treated with GA, it grew as tall as the pure tall plant. If this treated plant was crossed with a pure dwarf plant the phenotypic ratio of the \({{\rm{F}}_{\rm{2}}}\) is likely to be:
1 All tall
2 \(50 \%\) tall, \(50 \%\) dwarf
3 \(75 \%\) tall, \(25 \%\) dwarf
4 All dwarf
Explanation:
All will be dwarf as both the parent plants are dwarf, recessive for the character.
