Abstract

In the present investigation, we have attempted to identify the potential two epiphytic yeast strains for growth promotion and management of chilli fruit rot. Seed treatment with Pichia guilliermondii showed increased seedling vigour index (55%), fresh weight (96%) and dry weight (45%) over untreated control. Furthermore, P. guilliermondii showed higher root colonisation ability, indole-3-acetic acid (IAA) production and phosphate solubilisation ability. On the other hand, seedling dip with Hanseniaspora uvarum induced higher levels of defence-related compounds in chilli seedlings challenge-inoculated with Colletotrichum capsici under glasshouse conditions. Among the different media tested, higher biomass of P. guilliermondii and H. uvarum was obtained in pine juice broth and sugarcane juice broth, respectively. Glycerol buffer formulation showed viability (>70%) of P. guilliermondii up to 4 months and H. uvarum up to 9 months when stored at ambient conditions. Seedling dip and foliar sprays with H. uvarum showed 37– 40% reduction in chilli fruit rot incidence under field conditions. It also showed higher (cumulative) accumulation of defence-related compounds in chilli leaves and ripe fruits under field conditions. The results of current investigation indicated a clear difference among the two epiphytic yeast strains. P. guilliermondii was identified as growth promoter of chilli and H. uvarum as antagonist of chilli fruit rot pathogen, C. capsici.
