Abstract

This investigation was conducted under a naturally ventilated polyhouse, in the Department of Horticulture, SHUATS, Prayagraj, Uttar Pradesh. In December 2020 with records taken from the month of February to month of March 2021. There were nine treatments comprising two growth regulators Gibberellic acid (GA3) (at 200, 250, 300, and 350 ppm), and Naphthalic Acetic Acid (NAA) (at 50,100,150, and 200 ppm) along with control. The whole experiment was laid out as a Randomized Block Design (RBD) with three replications. The results revealed that among the Lilium cv. LITOUWEN, the foliar application of 250 ppm GA3 significantly increased the number of leaves per plant (66) with enhanced days to bud initiation (25.7 days). The number of bud per plant was 2.8 and stem length was 43.4cm respectively., GA3 at a concentration of 350 ppm enhanced vase life (7.9 days). and NAA at a concentration of 100 ppm enhanced the number of bulblets (3.3).
