Effects of of Exogenous Calcium on Plant Phenolic Compounds under Salt Tension 3.10. Effects Exogenous Calcium on Plant Phenolic Compounds below Salt Strain Subsequently, we studied the accumulation of phenolic compounds in in unique Subsequently, we studied the accumulation of phenolic compounds various tissues tissues treated with 100 mmol/L NaCl (S1), 100 NaCl + ten mmol/L CaCl (S1 + C2), and treated with one hundred mmol/L NaCl (S1), 100 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 had been determined by the LC S technique in methanol extracts of roots, stems, and leavesAgriculture 2021, 11,11 ofof G. sinensis, plus the types of compounds measured for the differently treated samples showed no distinction. It can be observed in the heat map that these compounds have been primarily divided into 3 groups around 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 inside the roots (Figure 7A). There was a slight improve but not important within the case of salt treatment alone, and a pretty substantial increase in case of exogenous calcium addition. The C6C1type compound (two,5-dihydroxybenzoic acid) and the.
