Standardization of hydro-priming for enhancing seed quality parameter in wheat (Triticum aestivum L.)

Abstract

Dry (moisture 13%) and the uniform seed of two varieties (Kharchiya-65 and KRL-210) of wheat were hydro-primed for 8, 16, and 24 hrs and subjected for examining the seed quality parameters namely germination percentage, root length, shoot length, seedling length, seedling dry weight, speed of germination, seedling vigour index, and conducted in Factorial Complete Randomize Design (FCRD) with three replications during Rabi season of 2017-18 and 2018-19. The maximum germination% (86.50%), root length (17.99 cm), shoot length (18.36 cm ), seedling length (35.23 cm), seedling dry weight (0.15 g), speed of germination (15.12) were obtained with 16 hrs hydropriming and seedling vigour index (2371) with 8 hrs in case Kharchiya-65 whereas the maximum germination (86.33), root length (13.89 cm), shoot length (13.9 cm), seedling length (28.50 cm), seedling dry weight (0.15 g), seedling vigour index (3045) was obtained with same 16 hrs and speed of germination (13.88) with 24 hrs showed the highest result in case KRL-210. The influence of hydropriming was more pronounced in KRL-210 as compared to Kharchiya-65. Thus, the seed quality parameters will be enhanced significantly by 16 hrs hydropriming in wheat.
