| Abstract:
In the present study, the effect of gibberellic acid (GA3) on vegetative growth and flowering of C. frutescens L. is investigated. The plants were sprayed with GA3 at either 250, 500 or 1000ppm, three times throughout the early stages of growth. The treatment with GA3 increased the height and diameter of plant, the number of shoots per plant and the length of shoots. GA3 accelerated flowering and decreased the number of inflorescence per plant. The fresh and dry weight of foliage and roots increased in response to GA3 but the fresh weight of inflorescence decreased. The chlorophyll and carotenoides increased by GA3 application. | |
