Abstract:

Marigold is one of the important annual flowers grown for commercial purpose all over the world. Non availability of high quality seeds of marigold is one of the major constraints in its cultivation. Priming of Marigold seeds plays crucial role in its germination and electrical conductivity, Hence a laboratory study was carried out to investigate the influence of various priming treatments on standard germination and electrical conductivity of French marigold seeds. This study was carried out on marigold seeds of four lines and nine treatments. Seeds treated with 0.5% KNO3 exhibited significantly highest germination (83.00%) during 0 month storage. In 2, 4, 6, 8 and 10 months storage duration, significantly maximum germination percentage was observed in T4 (81.33%, 75.33%, 69.33%, 60.91% and 44.25%) respectively. Maximum germination percentage was recorded in G-4(83.55%) which was followed by G-1 (79.33%) and G-3 (76.22%) during 0 month storage. In 2, 4, 6, 8 and 10 months storage duration, significantly maximum germination percentage was observed in G-4 (81.741%, 74.44%, 65.92%, 55.96% and 43.96%) respectively. The highest electrical conductivity was recorded in T0 (0.499ds/cm/seed) during 0 month storage. In 2, 4, 6, 8 and 10 months storage duration, significantly maximum electrical conductivity was observed in T0 (0.604 ds/cm/seed, 0.634 ds/cm/seed, 0.688 ds/cm/seed, 0.735 ds/cm/seed and 0.786ds/cm/seed) respectively. Maximum electrical conductivity was recorded in G-2(0.373ds/cm/seed) which was followed by G-3 (0.299ds/cm/seed) and G-1 (0.283 ds/cm/seed) during 0 month storage. In 2, 4, 6, 8 and 10 months storage duration, significantly maximum electrical conductivity was observed in G-2 (0.477 ds/cm/seed, 0.496 ds/cm/seed, 0.534 ds/cm/seed, 0.573 ds/cm/seed and 0.607ds/cm/seed) respectively.
