Jasmine is an important loose flower crop cultivated in Tamil Nadu. Growth is the irreversible change in size of cells and plant organs due to both cell division and enlargement. In J. auriculatum, spraying with ethrel at 1000 ppm recorded maximum growth retardation, CCC at 1000 ppm induced early flowering while SADH produced greater number of laterals producing flower clusters. Jasminum grandiflorum was sprayed with IAA, GA3, NAA, MH or TIBA at 10, 100 or 1000 ppm; CCC, SADH at 100, 1000 or 5000 ppm, and ethrel at 500, 1000 or 2000 ppm. All concentrations of IAA and GA3 increased shoot length, the most effective being IAA at 10 ppm which resulted in 12.6% increase in shoot length compared with untreated control. The foliar application of 500 g of ferrous sulphate and 100g of urea along with 100 ml of soap solution mixed in 100 litre of water is done two to three times at 20 days interval depending upon the extent of severity. By understanding the growth and development of Jasmine will lead to the continuous supply of flowers throughout the year.
