Abstract:
The present investigation the Study the impact of Salicylic Acid and Humic Acid on vegetative and flower bud production of Lilium Asiatic hybrid Tresor was carried out during the year 2018-19 and 2019-20, rainy season under the poly shade net structure of RKVY project, Department of Floriculture & Landscaping at Biotechnology-cum-Tissue Culture Centre Campus, O.U.A.T., Bhubaneswar. The trial was conducted separately for each cultivar with fourteen treatments and the treatments comprised of foliar application of Salicylic acid at T₁ (control), T₂ (250 ppm Humic acid), T₃ (500ppm HA), T₄ (750ppm HA), T₅ (1000ppm HA), T₆ (1250 ppm HA), T₇ (1500ppm HA), T₈ (50ppm Salicylic acid), T₉ (75 ppm SA), T₁₀ (100ppm SA), T₁₁ (125ppm SA), T₁₂ (150ppm SA), T₁₃ (175ppm SA), T₁₄ (200 ppm SA). The whole experiment was carried out following Randomized Block Design with four replications. Results revealed that T₁₄ 200 ppm SA recorded significantly vegetative and flower bud growth. Days for 100% sprouting of bulb, plant height (cm), number of leaves per plant, leaf area, leaf area index, total chlorophyll content, Days to appearance flower bud, Day to colour visibility in bud, Days to bud break, flower bud length (cm), flower bud width (cm) and initial weight of bud (g).
