Write the physiological effects of gibberellins in plant growth.
Physiological effects of gibberellins are:-
1. Elongation of intact stems:Many plants respond to application of GA by a marked increase in stem length; the effect is primarily one of internode elongation.
2. Dwarf shoots:Besides general increase in stem length, gibberellins specifically induce internodal growth in some genetically dwarf varieties of plants like Pea and Maize. It appears that dwarf- ness of such varieties is due to internal deficiency of gibberellins.
3. Bolting:Gibberellins...
