Abstract
In order to produce small-sized, compact and attractive potted models from yellow sage (Lantana camara L. cv. Flava), a trial was carried out at the nursery of Hort. Res. Inst., Giza, Egypt during 2022 and 2023 seasons using the growth retardant paclobutrazol (PP-333) at concentrations of 0, 25, 50, 100, 150 and 200 ppm as foliar spray to run-off, twice with three weeks interval in a complete randomized design, replicated thrice. The control plants were sprayed with tap water. Results of this trial showed that a linear decrease in the means of different vegetative and root growth parameters occurred as a result of the progressive increase in PP-333 concentration to reach the minimum by 200 ppm PP-333 treatment, which gave the least records at all in the two seasons. However, 150 and 200 ppm PP-333 treatments were statistically at par with each other for some traits. Also, PP-333 at 25 ppm concentration significantly increased fresh and dry weights of roots over means of control and all the other PP-333 concentrations in both seasons. A similar trend was also obtained regarding No. heads/plant, head diameter, peduncle length and head fresh weight characters. As for No. florets/head at opening stage, it was significantly decreased in the 1st season by 100, 150 and 200 ppm PP-333 concentrations, while in the 2nd one, that was occured by only both 150 and 200ppm ones. After the full open of florets, a great number of these florets was fallen and means of their number/head were gradually decreased with increasing PP-333 concentration, leading finally to a great deformation for the flowering heads, especially by 150 and 200 ppm concentrations. Besides, concentrations of chlorophyll a, b and carotenoids were progressively increased as the concentration of PP-333 was increased, but the opposite was the right concerning the percentages of total soluble sugars. Hence, it can be proposed to repeat this trial again to restore the floret falling problem.
