BIOXI15: PLANT GROWTH AND DEVELOPMENT
338023
The rosette habit of cabbage can be changed by application of:
1 IAA
2 GA
3 ABA
4 Ethaphon
Explanation:
The rosette plants (cabbage, spinach, etc.) generally do not flower into rosette form as they undergo a phenomenon called bolting just before flowering. In bolting, extensive internode elongation takes place, which prevents rosette formation. On application of gibberellin to certain cabbage plants, bolting is favoured and after some days, stem elongation was observed to a greater extent.
