“…Proline functions as an osmolyte and a radical scavenger, and it is synthesized in various cell compartments to combat stress conditions [55]. It also detoxifies cells by scavenging ROS [56]. Previous research has documented the accumulation of proline and soluble sugars as osmoprotectants against drought [57,58].…”

Sunflower (Helianthus annuus L.) is a major oilseed crop grown for edible oil throughout the world, including Pakistan. Drought stress is the most significant constraint to crop production in a changing climate scenario, and its severity is increasing day by day. Less rainfall and rising temperatures, particularly during the seed-filling phase, reduce achene yield in sunflower hybrids. Exogenous application of β aminobutyric acid (BABA) is effective in reducing the severity of terminal drought stress in many crop plants. Therefore, the present study was conducted to assess the effect of foliar BABA application on the membrane stability, growth, and productivity of sunflower hybrids under induced terminal drought conditions. A pot experiment was carried out to compare the growth and yield potential of two sunflower hybrids, Hysun-33 and NK-Senji, to two levels of water application: normal irrigation (NI) and terminal drought (TD). To combat terminal drought, four BABA concentrations (0, 20, 40, and 60 mM) were used. When compared to NK-Senji, Hysun-33 had the highest SPAD-chlorophyll value, head weight, 100-achene weight, and achene yield. In comparison to normal irrigation terminal drought
