Exogenous Cellulase Contributes to Mycoherbicidal Activity of Fusarium arthrosporioides on Orobanche aegyptiaca

Table 1

Correlation coefficients (r) across two fungal treatments of Orobanche aegyptiaca tubercle size, death, and days to death.

Infection parameter	Treatmenta	Correlation coefficient (𝑟)
		Size	Death	Day
Size	Mycelia alone	1.00
	Mycelia+cellulase	1.00
Death	Mycelia alone	−0.27^∗∗	1.00
	Mycelia+cellulase	−0.38^∗∗	1.00
Day	Mycelia alone	0.30^∗∗	−0.95^∗∗	1.00
	Mycelia+cellulase	0.38^∗∗	−0.92^∗∗	1.00

∗∗Correlation is significant at the 0.01 level; aMycelia = 7×10⁶ propagules ml^-1 of F. arthrosporioides; Cellulase = 20 U ml^-1 cellulase.
