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

Table 4

Some anatomical parameters in the two sensitive and resistant biotypes of E. crus-galli, that is, laminal thickness and vessel diameters after 14 days of treatment with fenoxaprop-p-ethyl compared with untreated ones.

Treatments	Laminal thickness; (μm)	Xylem vessels diameter; (μm)
Susceptible (control)	130^c	35^a
Susceptible + F	34^a	17^c
Resistance (control)	137^c	36^a
Resistance + F	51^b	25^b

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