Effects of 28-homobrassinolide and 24-epibrassinolide on the development of Meloidogyne incognita
International Journal of Nematology 15 (1), 43-47
Abstract: Second stage juveniles (J2) of Meloidogyne incognita were exposed for 48 hours in vitro, to six concentrations (ranging from 10^-5 M to 10^-10 M) of two of the most potent brassinosteroids, 28-homobrassinolide and 24-epibrassinolide. A higher mortality was observed in some of the concentrations of 28-homobrassinolide and 24-epibrassinolide. The treated juveniles were allowed to develop on tomato seedlings grown in pots filled with sterilized soil. The juveniles treated with brassinosteroids resulted in more galls and egg masses when examined after 45 days. The stimulating effect of 28-homobrassinolide and 24-epibrassinolide on the development of this root-knot nematode is indicated in these preliminary observations.
