Table 2. Colony diameters and conidiation of wild type Tv.223 and the chitinase-deficient mutants.

Strain	Colony diameter (cm)*				Conidiation (spores ml−1)
	12 h	24 h	36 h	48 h
Tv.223	1.87	4.03	5.52	6.57	4.88×107
?Tvnag1	1.82	4.03	5.50	6.60	5.09×107
?Tvnag2	1.82	4.03	5.53	6.67	3.97×107
?Tvnag1?Tvnag2	2.03	4.13	5.58	6.63	4.36×107
S.pNO8::hph	1.75	4.00	5.53	6.73	5.09×107
S.pOf28::hph	1.85	4.03	5.50	6.60	3.84×107

^*Each figure is the mean diameter of three replicate cultures.

Based on ANOVA (P<0.05), there were no significant differences in hyphal growth and conidiation between strains.
