Abstract
This experiment was carried out to study the efficiency of bio inoculants on Guizotia abyssinica (L.f) Cass plants genotypes on hydrolytic enzyme activty, Chlorophyll content. Four hydrolytic enzyme activities were activated in the roots from three varieties of Niger plantlets by all three (Pseudomonas aeruginosa, Azotobacter chroococcum, Glomus leptonica) bioinoculants. Celluase and Protease activity 0.0090, 0.0080 and 0.0088, 0.0081 µmoles/ml/min respectively in RCR-18 and DNS-4 varieties were found maximum from Pseudomonas aeruginosa, and Azotobacter chroococcum inoculums and peroxidase activity, Pseudomonas aeruginosa showed maximum enzyme activity 289.6 Units/ml. Similar trend of results was observed with Chlorophyll content since the highest records appeared with application of Pseudomonas aeruginosa in Guizotia abyssinica (L.f) Cass var RCR-18, recorded highest chlorophyll content with 2.36 gm /tissue. This study shows significant difference of Enzyme activity and growth enhancement with treatment of bio-inoculants.
