| Abstract | ||||
| This investigation was carried out during the two successive summer seasons of 2005 and 2006 on sweet pepper cv. Marconi, to study the effect of spraying with some growth regulators (10 ppm GA3 and 10 ppm NAA) and 200 ppm Zn as well as different combination treatments among them at flowers initiation on growth, fruit physical characters, yield and some chemical constituents of fruits. Spraying plants grown under high temperature with 10 ppm GA3, 10 ppm NAA, 200 ppm Zn or different combination treatments between them led to improving plant growth (plant height, number of branches and leaves/plant, fresh and dry weight/plant and leaf area), fruit length and diameter, number and weight of fruits/plant, early and total yield and chemical constituents (NPK, total chlorophyll, vitamin C, total soluble solids and zinc) as compared to control (water spray). In general, the best treatment for increased vegetative growth, fruit physical characters, yield and chemical constituents in fruits was sprayed plant at flowers initiation with 10 ppm GA3 + 10 ppm NAA+ 200 ppm Zn as compared to other treatments. | ||||
