| dc.description.abstract | Zucchini plants (Cucurbita pepo L. cv. Rceel F1) were subjected to different types of soil and NaCl as a source of salinity with irrigation to investigate the effect type of soil on vegetative growth and reproduction under salinity conditions. Two types of soil (clay soil, and sandy soil) were used with three levels of salinity: 2000 (tap water), 4000, and 6000 ppm. Leaves number (LN), leaf area (LA), fresh weight of shoot (FWS), fresh weight of root (FWR), dry weight of shoot (DWS), and dry weight of root (DWR) of the plant were measured for each treatment. Leaf contents of nitrogen (N), phosphorus (P), and potassium (K+) in leaves were determined. Treatment with salinity (4000 and 6000 ppm) reduced (LN), (LA), (FWS), (FWR), (DWS), and (DWR) for all types of used soil. The saline treatment reduced the leaf content of N, P, and k+ compared to the control. While, increasing the salinity of irrigation water harmed the male flower (MF), female flower (FF), the total number of flowers (TF), the percentage of female flowers (PFF), and the sex ratio of female flowers (SR) in all the concentrations used, whether clay or sandy soil. Whereas, the effect of salt stress was more severe on zucchini plants grown in sandy soil compared to clay soil. On the other hand, plants grown in clay soils were less sensitive to increased salinity concentrations than plants grown in sandy soils in the measurements of vegetative growth and reproductive stage | en_US |
