Abstract:
Wheat (Triticum aestivum L.) is amongst the most important foods. High concentration of salinity critically affects most of the plants, specifically wheat. In current study, the impact of ascorbic acid (AsA) to decrease salinity stress was inspected in two commercial cultivars of wheat (Punjab 85, Okaab 2000). Experiment was carried out with three replications in 36 plastic pots filled with 8kg sand in each pot. Two salinity levels (0, 120 mM) with foliar application of ascorbic acid (0, 50 mM, 100 mM) were applied after germination of wheat. After 18 days of salinity treatment, foliar application of AsA was applied. After 3 weeks of treatment, data about biochemical, physiological and yield properties were noticed by standard procedure. The experiment was conducted in UAF Community College PARS under a completely randomized design (CRD) and results were analyzed by using CO-STAT software and means of treatment was compared by using Tukey’s test at 5% level of significance. Under salinity stress, application of AsA significantly (p=0.05) enhanced morphological parameters such as (Plant height, SL, RL, SFW, RFW, SDW, RDW, LL, LW, LA and Number of leaves per plant) yield (i.e., number of branches per plant, number of pods per plant and number seeds per pod) key physiological attributes (such as chlorophyll a, chlorophyll b, carotenoids, total chlorophyll and chlorophyll ratio) and biochemical parameters (i.e., Na+ , K+ and Ca²+ ions) in experimental varieties of wheat. Overall results explained that wheat cultivar Punjab 85 reduce the salt stress and shows better growth than Okaab 2000 under salt stress. It is revealed from this study that AsA mitigate the salt stress in wheat.
