Comparative analysis of seed priming on the germination and growth of lentil landraces (Lens culinaris Medik)

Abstract

Seed priming was carried out to determine the effect of different priming agents on seed germination and growth of different landraces of lentils. The two factorial experiments were carried out in a completely blocked design of which one factorial is of 7 treatments, i.e., PEG (10%), boric acid (0.1%), urea (2%), PEG (5%), DAP (2%), CaCO3 (2%) and Control. Other landraces, Sunwarshi-LR1 and Rangeli-LR2, collected from two different locations in the Morang district, were replicated three times. The overall germination performance is better on landraces Sunwarshi-LR1, but no significant difference was observed in individual treatment. The interaction between the two landraces seems effective in germination and germination energy, whereas non-significant in germination speed and vigor index. The shoot length seems non-significant at 10 and 20 DAS, and a significant result was obtained at 30 DAS. The root length seems important at 10 DAS, whereas non-significant at 20 and 30 DAS. Sunwarshi-LR1 shows better performance with PEG (10%).
