Abstract:
An investigation was undertaken to study the effect of growth retardants on growth and post-harvest parameters of nerium cv. Pink Single at College of Horticulture, Mysuru during 2020-2021. The growth retardants used were PCB (150, 250 and 350 ppm), MH (1500, 2000 and 2500 ppm) and SADH (1500, 2000 and 2500 ppm) in randomized block design with three replication. Among different treatments, MH at 2500 ppm gave maximum reduction in plant height (127.53 cm), internodal length (4.45 cm) and individual leaf area (36.07 cm2). However maximum plant spread in (111.00 cm) North – South and (116.60 cm) East – West direction, number of secondary branches (53.80) and chlorophyll content (1.91 mg/g) with minimum physiological loss of weight (8.40 %) and extended shelf life up to 10.16 hours was also noticed with the same treatment.
