Response of seed bio-priming on chilli (Capsicum annum L.)

Abstract

This study was conducted to determine the effect of bio-priming with Trichoderma viride and Pseudomonas fluorescens on qualitative parameters of chilli. Culture broth of Trichoderma viride strain Tv-4 and Pseudomonas fluorescens strain Psf- 2 were utilized for the purpose of pre-sowing bio-priming of seeds of five chilli genotypes viz., Ac- 574, Ac- 615, Bcc-62, Hyb(3)2 and Pant C1 in consecutive two years (2012 and 2013). Bio-priming was significantly improved by the capability of these strains and the highest amount germination percentage at first count 77.25% with, Germination percentage at final count (97.25%), seedling length (12.85 cm), root length (9.25cm) and seedling vigour index (1175.00) reached, in comparison with the control. Therefore, we reported that application of Trichoderma viride and Pseudomonas fluorescens are the effective biological agents on chilli seed germination and their seedling parameters.
