Host response of Capsicum frutens cultivar ‘Capistrano’ to Meloidogyne incognita race 2

Figures & data

Table I. Initial nematode population density, final nematode population density and reproductive factor of Meloidogyne incognita race 2 on Capsicum frutens cultivar ‘Capistrano’ in two microplot experiments at 120 days after inoculation (n = 30).

Variable	Experiment 1	Experiment 2
Final nematodes (Pf)	5904	3658
Initial nematodes (Pi)	11,000	11,000
Reproductive factor	0.54	0.33
Reproductive factor = Pf/Pi.
