ABSTRACT
In present study, seeds of five cultivars of okra viz. Arka Anamika, Pusa Sawani, Arka Veena, Jai Jawan-Jai Kisan and Parbhani Kranti were used to study the toxicity of culture filtrate (CF) of Rhizoctonia bataticola on viability, germination & seedling growth of okra. The viability of excised embryos was assayed by Tetrazolium Chloride test. It was decreased by 4, 16 and 24 h treatments with CF respectively. Complete loss of viability was observed in 30 h CF treated embryos as no staining took place. Embryos with 16 h of CF treatment showed a decrease in viability of seeds in all 5cultivars. Seeds of all cultivars soaked in distilled water for one day and treated separately for 24 h with CF. In CF treated seeds of all cultivars, germination was decreased 42, 58, 46, 69 and 40 % as compared to the control (non CF treated seeds) 70, 76, 82, 91 and 80 % respectively on 8th day of incubation. Maximum symptomatic seedlings (radical browning & brown- black streaks on hypocotyls) and seedling mortality were observed in Arka Anamika (83.33%, 45.71 %) and Prabhani Kranti (70%, 46.42 %) as compared to control of each cultivar (2, 2% respectively). CF treatment of pathogen caused severe toxic effect on seedling growth of already germinated seeds of all 5 cultivars.
Key words: CF R.bataticola, seed viability, seed germination, seedling growth, okra cvs.
