Salicylic Acid Modulates Grain Growth and the Activity of Carbohydrate-Metabolism Enzymes Differentially in Bold and Small Wheat (Triticum aestivum L.) Grains
Wheat grain weight is co-limited by assimilate supply and by the grain’s capacity to convert sucrose into storage starch, a capacity that is far lower in slow-filling small (inferior) grains than in bold (superior) grains and that depresses both yield and uniformity. Whether salicylic acid (SA) can strengthen this capa...
