Resumo: Paclobutrazol (0, 5, 25, 50 and 100 mg/plant) was applied to soil in potted plants of 12 citrus cultivars propagated by tissue culture and seedlings. Required quantity of active ingredient of paclobutrazol was applied in 100 ml of water around the base in polythene bags and control plants were given 100 ml of water. The treatments were applied on 4 month old seedling. Six randomly selected plantlets were used for recording morphological observations at the age of one year. Results indicated that all citrus types were sensitive to paclobutrazol. Overall growth of seedlings was checked by paclobutrazol application. Treated plants produced shorter internode, shorter/thicker roots and reduced plant height and dry weight. Micropropagated plants seem less responsive to paclobutrazol than seedlings this might result in an increase in secondary roots of seedlings at early stage than micropropagated plantlets, which helped plants in absorption of paclobutrazol.
