Effects of of Exogenous Calcium on Plant Phenolic Compounds under Salt Anxiety 3.ten. Effects Exogenous Calcium on Plant Phenolic Compounds below Salt Strain Subsequently, we studied the accumulation of phenolic compounds in in distinctive Subsequently, we studied the accumulation of phenolic compounds distinct tissues tissues treated with 100 mmol/L NaCl (S1), 100 NaCl + 10 mmol/L CaCl (S1 + C2), and treated with 100 mmol/L NaCl (S1), one hundred mmol/L mmol/L NaCl + 10 mmol/L CaClnormal growth state (CK). Visualization of phenolic materials was performed by hierarchical cluster evaluation (Figure six). Twenty-three phenolic compounds and L-phenylalanine were determined by the LC S method in methanol extracts of roots, stems, and leavesAgriculture 2021, 11,11 ofof G. sinensis, plus the forms of compounds measured for the differently treated samples showed no distinction. It might be seen in the heat map that these compounds have been Benzimidazole supplier mostly divided into 3 groups on the basis of their tissue-specific accumulation patterns and participated in salt tension responses to varying degrees. The C6C3-type compound (p-hydroxycinnamic acid, p-coumaric acid), the C6C3C6-type compound (naringenin, glycyrrhizin, genistein, quercetin), and L-phenylalanine have been mostly accumulated within the roots (Figure 7A). There was a slight raise but not important in the case of salt remedy alone, plus a incredibly considerable enhance in case of exogenous calcium addition. The C6C1type compound (two,5-dihydroxybenzoic acid) and also the.
