Table 2. Plant height and shoot and root weight of the different Echinochloa crus -galli populations and the percentage difference of these growth parameters for each salt concentration compared with the control.

	NaCl		Plant height difference compared with		Shoot weight difference compared		Root weight difference compared
aLowercase letters refer to a comparison of the plant height and shoot and root weight of E. crus-galli for NaCl concentrations within the same population. bThe plant height and shoot and root weight variations of E. crus-galli among populations are indicated in lowercase letters in italics, lowercase letters in bold, and uppercase letters for 50, 100, and 150 mM concentrations, respectively. Different letters indicate significantly different values, according to Tukey’ s honest significant difference test. Where no letters are present, the comparison was not significant.
