Table 2 Correlation matrix between pH, EC, and GI (48 and 144 h) for BSG 1:25, FPR 1:100, and LPR 1:200 aqueous extracts

From: Extraction and characterization of bio-effectors from agro-food processing by-products as plant growth promoters

		GI (48 h)	GI (144 h)
BSG	pH	0.72	Nd
BSG	EC	−0.86	Nd
FPR	pH	−0.76	−0.75
FPR	EC	−0.85	−0.85
LPR	pH	0.92	0.89
LPR	EC	−0.40	−0.71

GI, germination index at 48 h and 144 h; BSG, brewers spent grain; FPR, fennel processing residues; LPR, lemon processing residues; Nd, not determined.
Values in bold indicate significant P = 0.05 (two-tailed test).
