Seed bio-priming with Pseudomonas fluorescens isolates enhances growth of pearl millet plants and induces resistance against downy mildew

摘要: Biopriming pearl millet seeds with Pseudomonas fluorescens isolates resulted in improved growth of the plants and also induction resistance against downy mildew disease caused by fungus Sclerospora graminicola. Although all test reduced severity promoted both under greenhouse field conditions, high variability was observed their efficiency. Treatment due to enhancement of: germination, seedling vigour, plant height, leaf area, tillering capacity, seed weight (measured for 1000 seeds) yield. The time required flowering advanced 5 days. Isolate UOM SAR 14 registered higher levels vegetative reproductive growth; most importantly there a 22% increase grain effectively induced resistances conditions. offered protection ranging from 20 75%. However, level control less than that achieved systemic fungicide Apron. 71 75% remained consistent Further studies showed systemic, minimum 3 days build up, sustained throughout plant's life.
