Table 2.

Mean latent period following TGMV or SCTV inoculation of Nicotiana benthamiana plants in the absence or presence of exogenous cytokinin treatment

Virus Inoculum	Dose	− BAP	+ BAP
TGMV A + B	1.0	13.9 ± 1.3 (15/18)	12.7 ± 0.7 (18/18) ^a
	0.2	13.4 ± 1.8 (11/15)	11.4 ± 0.9 (17/18) ^a
Wild type SCTV	0.04	8.6 ± 0.7 (18/18)	7.9 ± 0.4 (18/18) ^a
	0.008	9.1 ± 0.7 (18/18)	7.8 ± 0.4 (18/18) ^a
SCTV c2-4 mutant	0.04	9.4 ± 0.8 (17/17)	9.1 ± 0.6 (17/17) ^b
	0.008	11.0 ± 1.2 (17/17)	9.0 ± 0.5 (18/18) ^a

Note: Plants were agro-inoculated with TGMV or SCTV as described in the Materials and Methods. Plants were scored for the appearance of systemic symptoms typical of TGMV or SCTV infection. Lower case superscripts indicate significant differences in the mean latent period (days post inoculation ± SE) observed in the absence or presence of BAP as confirmed by ANOVA

P<0.05;

P<0.10

Numbers in parentheses indicate infectivity (number of plants infected/number plants inoculated).
