Effect of Methyl Jasmonate on Phytoalexins Biosynthesis and Induced Disease Resistance to Fusarium oxysporum f. sp. Vasinfectum in Cotton (Gossypium hirsutum L.)

Figure 3

Protective effect of exogenously applied MeJA on cotton against fusarium wilt caused by Fusarium oxysporum f. sp. vasinfectum. Prior to inoculation, leaves were treated with MeJA 5.0 mM and were incubated at 72 h (0 day) at 25°C for 38 days. Disease severity was evaluated by noting every two days the stem height (a) and diameter increase (b) as well as the number of healthy attached leaves (c). TI: MeJA/infected plants; NTI: no-MeJA/infected plants; NTNI: no-MeJA/no-infected plants.
