Effect of Salinity Stress on Growth, Productivity and Fruit Quality of Two Strawberry Hybrids

Abstract

The experiment was carried out in Abu Jarash farm, during the growing season 2021 in order to study the impact of salinity stress (NaCl) on growth, productivity and the fruit quality of two strawberry hybrids (Azogrande and Festival). Strawberry seedlings were planted using four levels of salt (NaCl)(0, 50, 100, 150 mM) in plastic pots (2 liters capacity). Filled with a mixture of peat moss and pearlite 3:1), the experiment was designed according to a randomized complete block design.The leaf area of ​​the plant decreased significantly at all studied salinity levels compared with the control (non-stressed saline) by 14.92, 37.81, 55.99%, respectively, and the productivity was recorded at 102.42 g/plant at the concentration 150 mM compared to the control 505.43 g/plant. While the quality parameters (acidity percentage, total soluble solids percentage, vitamin C) for the fruits improved under the influence of the studied treatments, acidity percentage was 0.71, 0.63, 0.55, 0.43 and the percentage of total soluble solids was recorded as 6.98, 8.46, 9.98, 10.86 and for vitamin C it was recorded. 35.34, 43.00, 39.00, and 48.66 for coefficients.The Azogrand hybrid was significantly superior in all the studied morphological and qualitative characteristics over the Festival hybrid.
