Acadian Marine Plant Extract treated corn, cv. 'Bilicious', under limiting phosphorous (P) conditions, showed significantly increased leaf area, increased total root length, increased fresh weight of shoot, increased dry weight of shoot, no difference in percentage water content (PWC) of shoot, no difference in fresh weight of root, increased dry weight of root, no difference in PWC of root, no difference in N, increased P (47%), no difference in K, no difference in Ca, increased Mg (29%), no difference in Na, decreased Fe (-13%), increased B (+8%), increased Mn (+12%), increased Zn (+15%), increased Cu (+27%), increased chlorophyll a, increased chlorophyll b, increased carotenoids, decreased anthocyanins, decreased membrane leakage, increased membrane stability index, decreased MDA content, decreased 02 content, decreased H20 content, increased total soluble sugar, no difference in total amino acids, no difference in total phenolic content and decreased flavonoid content, compared to untreated control plants. Furthermore, biostimulant application significantly regulated the Expression of Genes Involved in P homeostasis, carbohydrate metabolism, lipid metabolism and secondary metabolism in Z. mays Grown Under P-limited Conditions.
