Abstract:

Under greenhouse conditions, okra (Abelmoschus esculentus (L.) Moench) cv. Baladi, highly susceptible to Meloidogyne incognita root-knot nematode, was tested as trap crop for managing this pest. Plants were uprooted from the infected soil 4, 8, 16, 24, 32 and 48 days after namatode inoculation. M. incognita began to develop to mature females after the 8th day from nematode inoculation. Then, it started to lay eggs in gelatinous matrices after the 16th day form nematode inoculation. To pull out okra susceptible cultivar within the period after the 16th day from nematode inoculation. Cellular alternations in the root of okra resulting from infection with the root-knot nematode, M.incognita were studied. The feeding site (gaint cells) of the namatode was mainly confined in the stele region. Cells of the feeding site showed thickening of cell were surrounded by hyperplasia cells. Gaint cells in a cluster had distinct, thickened boundary walls and occupied the stele region.
