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, shoot length and root length. Hence a laboratory study was carried out to investigate the influence of various priming treatments on shoot and root length 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 higher shoot length (10.950cm) during 0 month storage. In 2, 4, 6, 8- and 10-months storage duration, significantly maximum shoot length was observed in T4 (9.217cm, 7.225 cm, 6.500 cm, 4.758 cm and 3.458 cm) respectively. Maximum shoot length was recorded in G-4(9.36cm) which was followed by G-1 (8.40 cm) and G-3 (7.85cm) during 0-month storage. In 2, 4, 6, 8- and 10-months storage duration, significantly maximum shoot length was observed in G-4 (8.03cm, 6.763cm, 5.752cm, 4.785cm and 2.956cm) respectively. Seeds treated with 0.5% KNO3 exhibited significantly higher root length (4.625cm) over the other treatments during 0-month storage. In 2, 4, 6, 8- and 10-months storage duration, significantly maximum root length was observed in T4 (4.175cm, 3.908 cm, 3.275 cm, 2.158 cm and 0.983 cm) respectively. Maximum root length was recorded in G-4(4.877cm) which was followed by G-1 (4.709 cm) and G-3 (4.350 cm) during 0-month storage. In 2, 4, 6, 8- and 10-months storage duration, significantly maximum root length was observed in G-4 (3.933 cm, 3.315 cm, 2.644cm, 1.959 cm and 0.937 cm) respectively.
