PLANT PROMOTING ACTIVITIES OF FUNGAL ENDOPHYTES ASSOCIATED WITH TOMATO ROOTS FROM CENTRAL HIMALAYA, INDIA AND THEIR INTERACTION WITH PIRIFORMOSPORA INDICA
Endophytic fungi promote plant growth through the production of IAA, siderophore and phosphate solubilization. Out of thirty fungal endophytes isolated from tomato roots grown in a stressed, cold climate of Central Himalayan hills of district Pithoragarh, Uttarakhand, India twelve showed distinct morphological and study was undertaken, to understand the plant growth promoting properties possessed by these endophytes residing under stress environment. All the fungi showed the zone of phosphate solubilization, seven were positive for siderophore, four for HCN and three-showed ammonia production. IAA production was found maximum in lessThan i greaterThan Fusarium fusarioides. lessThan /i greaterThan All the endophytic fungi showed remarkable phosphate solubilizing activity up to eight days with a decrease on the 10 lessThan sup greaterThan th lessThan /sup greaterThan day with maximum reporting from lessThan i greaterThan Trichoderma peudokoningii lessThan /i greaterThan . All the isolates showed maximum siderophore production at 21 lessThan sup greaterThan th lessThan /sup greaterThan day after the inoculation. These isolated root endophytic fungi possess plant growth promoting properties and thus have a potential to be used for biofertilizer.
