Table 1.
Growth parameters of lettuce seedlings subjected to C. vulgaris (LsCv) and S. quadricauda (LsSq) treatments (LsCK: control; FW: fresh weight; DW: dry weight; RGR: relative growth rate). Different letters indicate significance according to Fisher’s protected LSD test (P = 0.05); *, **, and ***: significance of P ≤ 0.05, 0.01, and 0.001, respectively. ns: not significant.
