Identification and Mechanism of Echinochloa crus-galli Resistance to Fenoxaprop-p-ethyl with respect to Physiological and Anatomical Differences

Table 2

Chlorophyll contents in susceptible and resistant biotypes of E. crus-galli after 14 days of treatment with fenoxaprop-p-ethyl compared with untreated ones.

Treatments	Chlorophyll pigments (mg/L)
	A	B	Total
Susceptible (control)	3.001^a	1.785^a	5.211^a
Susceptible + F	1.872^c	0.552^d	2.425^d
Resistance (control)	2.494^b	1.461^b	3.956^b
Resistance + F	1.458^d	1.175^c	2.633^c

^∗F = fenoxaprop-p-ethyl.
^a,b,c,dindicate the significance and non-significance between means using Duncan multiple range test.
