Due of its great commercial and decorative value, lilies are in high demand as cut flowers or landscape plants all over the world. The use of biostimulants has attracted attention in the horticulture sector as a novel and promising strategy to guarantee increased and long-lasting yields as well as superior product quality. Current study investigating the “Effect of zeatin and kinetin on growth and quality of lilium lancifolium grown in Haripur region”－was carried out at Horticulture Nursary, The University of Haripur, Pakistan during 2020-2021. Following concentrations of Zeatin and Kinetin were applied as foliar spray after 12 days after sowing. Each treatment was prepared by standard procedures: To = Control, T1= 0.1% Zeatin, T2= 0.1% kinetin, T3=0.1% Zeatin and 0.1% kinetin. The data was collected after the foliar spray of zeatin and kinetin with 10 days’ interval, SD1: 10 days after spray, SD2: 20 days after spray, SD3: 30 days after spray, SD4: 40 days after spray. Results reviled that application of 0.1% Zeatin and 0.1% kinetin and data observed after 40 days of spray resulted in significantly higher total number of leaves plant-1, total number of petals plant-1, plant height (cm), flower diameter, leaf area, total number of flowers plant-1. Chlorophyll content and photosynthetic rate of lily flower showed significant result for treatments applications and days after spray, whereas, their interaction remained non-significant. Protein content was affected significantly from treatments application only. From this study it is concluded that foliar application of 0.1% Zeatin and 0.1% kinetin helps in enhancing the growth and yield of lily flower and also found very effective in maintaining the quality of lily fruits under Agro-climatic conditions of Haripur region.
