| Popis: | A greenhouse experiment was carried-out to evaluate the effect of three rates of salinity as abiotic stress on okra plants (Abelmoschus esculentus) infected with the root-knot nematode (Meloidogyne incognita) as biotic stress. Plant lengths and weights were significantly (p ≤ 0.05) reduced except root weight and there was a positive correlation between increasing the salinity concentration from 0.1 to 0.3% and increasing the rate of reduction in plant criteria. The number of J2 in soil, galls, and eggmasses were decreased linked to increased salinity rate as compared to nematode control treatment. However, peroxidase and catalase activities were significantly reduced linked to increasing the salinity concentration from 0.1 to 0.3%. There was no significant difference between total phenols at all treatments. Meanwhile, there was no significant improvement in N, P, and K contents whereas photosynthetic pigments (a, b) and carotene were significantly (p ≤ 0.05) reduced by nematode infection and incre... |
