| Abstract | The objective of this study was to evaluate the effect of using paclobutrazol or glutathione with levels of 0, 50, 100 and 150 mg/l on plant growth, flowering and some chemical composition of Calendula officinalis L. plant grown at the green house of National Research Centre, Giza, during two successive seasons of 2003-2004 and 2004-2005.The obtained data indicated that foliar application of most paclobutrazol treatments significantly decreased plant height compared with control treatment while number of branches, fresh weight and dry weight of leaves per plant were increased. All growth parameters were significantly promoted by foliar application of glutathione. In most collections foliar application of glutathione at 150 mg / l gave the highest significant increase in number of flowers/plant, fresh weight of flowers (g/plant) and dry weight of flowers (g/plant) followed by paclobutrazol 100 mg/l compared with untreated plants. Foliar application of glutathione at 150 mg/l recorded the highest values of chlorophyll a and chlorophyll b. However, paclobutrazol and glutathione showed no significant increase in carotenoids contents. The maximal value of total carbohydrates (37.64%) was obtained when 150 mg/l glutathione was applied followed by paclobutrazol (31.42%) at le 1 vel of 100 mg/l and total nitrogen percentage had the same trend. |
