Antagonism of Sesame To the Root-Knot Nematode (Meloidogyne Incognita) On Okra in Tissue Culture

Allelopathy

“…While studying the effect of root leachates on in vitro hatching, Ahmad and Khan (1964) observed that it was suppressed by the leachates of some non-host plants. The excised roots of sesame were also shown to inhibit the hatching of M. incognita in tissue culture studies (Tanda et al, 1988). The excised roots of sesame were also shown to inhibit the hatching of M. incognita in tissue culture studies (Tanda et al, 1988).…”

“…Roots of actively growing plants secrete a variety of allelochemicals in the soil . Tanda et al (1988) demonstrated in axenic tissue culture that exudates originating from sesame (Sesamum sp.) Griffin and Waite (1971) reported that when eggmass of M. hapla was placed on a water agar plate equidistant from germinating susceptible and resistant alfalfa seeds, approximately 75% of the hatched juveniles were attracted to the susceptible and only 25% to the resistant seedlings.…”
