Abstract:
Spinach (Spinacia oleracea L.) is an annual, leafy, green flowering plant. Salt stress is an environmental factor that would affect the growth attributes of spinach crop. Using thiourea as a foliar spray to ameliorate salt stress would beaneconomically consistent approach. For this purpose, a pot filled experiment was conducted in Old Botanical Garden University of Agriculture, Faisalabad. Sowing was done with each pot contain 15 seeds of spinach, the crop was planted in 24 pots and each pot was filled with sand. After germination of plants, Hoagland solution was applied to spinach plants. Two levels of salt stress (0 and 150 mM) along with Hoagland’s solution were applied to crop. Harvesting was carried out and different parameters were recorded. Recorded data were analyzed by using CO-STAT software. Data showed, salinity increased several growth metrics along withchlorophylla, chlorophyll b, and total chlorophyll, whereas other spinach growth factors were unaffected by salt stress.Exogenouslyapplied thiourea dramatically enhanced the number of leaves, catalase, and peroxidase in spinach plants, but other spinach plant characteristics were unaffected by the foliar administration of thiourea. Other parameters such as shoot fresh weight, root fresh weight, shoot dry weight, root dry weight, root length, chlorophyll a, chlorophyll b, carotenoids, total chlorophyll, chlorophyll a/b ratio, SOD, TSP, MDA H2O2, Na+, K+, and Ca2+ remained unchanged as a result of the combined effect of salinity and thiourea.
