| Abstract | ||||
| Two-years pot trials were conducted at Orman Botanical Garden, Giza, Egypt, throughout the 2000/2001 and 2001/2002 seasons, to find out the effect of foliar applications of cycocel ancymidol and paclobutrazol growth substances at three concentrations for each on growth, flowering and chemical constituents of Rosa polyantha cv. Carriere, Sprays were applied twice at April and July. The results obtained revealed that the 100 ppm ancymidol and 200 ppm paclobutrazol treatments markedly reduced plant height, hastened flowering and increased number of flowers/plant and total chlorophylls. However, ir.significant differences in dry weight, total carbohydrates, Fe, Mg and Ca contents in different parts of the plant. | ||||
