520			_aThe present investigation was 'carried out at Faculty of Agriculture Farm, during 1999 and 2000 growing seasons, Department of Agric. Botany, Faculty of Agriculture, Kafr EISheikh, Tanta University. The main objective of this investigation is: to study the effect of foliar spraying of the three PGRs i.e., Pix, Kinetin and Morphactin with two concentrations for each one (low and high) and three micronutrients i.e., iron (Fe), zinc (Zn) and manganese (Mn) with one concentration of each one, and their combinations; on: vegetative growth of cotton plants, , leaf pigments and some chemical constituents of cotton plants. The cotton cultivar was devoted in this study is Giza 86 an Egyptian long staple. The main obtained results may be summarized as follows: • Pix application 1000 and 2000 ppm significantly decreased plant height, leaf area and dry weight of leaves. • Kinetin applications (25 and 50 ppm) significantly promote plant growth by increasing plant height, leaf area and dry weight of leaves, compared to the control plants in both seasons. • Morphactin applications (10 and 20 ppm) slightly increased the vegetative characteristics compared to the control in both seasons. • Micronutrients applications (Fe. 2000 ppm, Zn, 1500 ppm. and Mn. 1000 ppm) significantly increased plant height, and dry weight of leaves, While zinc (Zn) only, significantly increased leaf area/plant. • Combined treatments (PGRs + microelement) slightly improved most of growth characteristics.'
