Abstract
Tuberose (Polianthes tuberosa L.) is a popular flower that is available in both cut and loose form. It has potential to earn more foreign exchange because of attractive color, good display life and high market essential oil value. Pakistan's cut flower business is still in its early phases of growth, with producers growing cut flowers only in open fields. Flower forcing is an operation or treatment to the plant after it goes the ripeness to flower stage. It aims to stimulate the flower at a specific date during an off-season period. Chemical flower forcing can be done through the application of fertilizers and plant hormones including gibberellin. Gibberellic acid is a plant hormone that promotes plant development and improvement and it is a good growth promoter. Micronutrients are necessary for plant growth and development Present study was conducted at Research Area Department of Horticulture, Pir Mehr Ali Shah Arid Agriculture University Rawalpindi during 2021-2022.The study was comprised of three different level of two different chemical, gibberellic acid and Epsom salt (MGSO4) applied to plants through soaking of bulbs for 24 hours i.e T0 (Control/untreated),T1(gibberellic acid 100ppm/L),T2(gibberellic acid 200ppm//L),T3 (gibberellic acid 300ppm//L) and T4 (MGSO4 15gm/L), T5 (MGSO4 30gm/L) and T6 (MGSO4 45gm/L) respectively. Key words: Tuberose; Gibberellic acid; MgSo4, flower forcing, Epsom salt, Off-Season
