Standardization of planting materials and effect of plant growth regulators on tuberose (Polianthestuberosa L.) cv. Arka Prajwal


Author(s): Loganayaki P, Sankari A and Gopitha

Abstract: A field experiment entitled “Standardization of planting materials and effect of growth regulators on tuberose (Polianthes tuberosa L) cv. Arka Prajwal” was conducted during 2018-2019 at the Department of Floriculture and Landscaping, Horticultural College and Research Institute, Tamil Nadu Agricultural University, Coimbatore. Different sizes of bulbs treated with GA3 @ 150 ppm and control (distilled water) for 24 hours before planting after removal scales and bulblets of tuberose cultivar “Arka Prajwal” were used in the experiment. The observations were recorded at nursery stage and after planting. Among the different sized bulbs and bulblets, bulbs cut into two halves(T2), bulbs cut in four halves(T3) and bulblets(T4) was found to be more effective planting material with regard to nursery stage growth parameters. Among this, bulbs cut into two halves (T2) significantly increased characters viz., days taken for sprouting and 70% sprouting (4.50 and 9.0 days), number of sprouts (90%), sprouting percentage (100%), plant vigour (2220.0) and also bulbs cut into two halves (T3) was maximum for characters like plant height (19.0 and 28.35 cm), leaf length (13.20 and 26.55 cm) on 30th and 60th day after planting.
