Effects of of Exogenous Calcium on Plant Phenolic Compounds under Salt Pressure 3.10. Effects Exogenous Calcium on Plant Phenolic Compounds beneath Salt Tension Subsequently, we studied the accumulation of phenolic compounds in in distinct Subsequently, we studied the accumulation of phenolic compounds unique tissues tissues treated with one hundred mmol/L NaCl (S1), 100 NaCl + ten mmol/L CaCl (S1 + C2), and treated with 100 mmol/L NaCl (S1), 100 mmol/L mmol/L NaCl + ten mmol/L CaClnormal growth state (CK). Visualization of phenolic components was performed by hierarchical cluster evaluation (Figure 6). Twenty-three phenolic compounds and L-phenylalanine had been determined by the LC S technique in methanol extracts of roots, stems, and leavesAgriculture 2021, 11,11 ofof G. sinensis, and also the sorts of compounds measured for the differently treated samples showed no difference. It may be noticed in the heat map that these compounds have been mainly divided into 3 groups on the basis of their tissue-specific accumulation patterns and participated in salt strain 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 mainly accumulated within the roots (Figure 7A). There was a slight enhance but not significant inside the case of salt treatment alone, as well as a really important raise in case of exogenous calcium addition. The C6C1type compound (two,5-dihydroxybenzoic acid) plus the.
