Biopriming of pea seeds with native Trichoderma species for enhanced seedling vigour
Keywords:Biopriming, pea, root, shoot, seedling vigour, Trichoderma.
AbstractThe current study was carried out to evaluate the effect of seed biopriming using eight native Trichoderma isolates in pea. The seeds of pea variety (Rachna) were primed in Trichoderma isolates and as a control treatment seeds without priming were used. Results exhibited that seed priming by Trichoderma species considerably enhanced the germination of seed and its seedling vigour against the control. Among the different treatments tested, isolate NCIPMCAU-69 showed the maximum root length (5.63 cm), shoot length (0.85 cm), and vigour index (648.00). In untreated control, the root length, shoot length, and vigour index are 1.94 cm, 0.35 cm, and 152.67, respectively. The lowest per cent germination of 66.67% was observed
in NCIPMCAU-7 and control.
