Jasminum sambac L, Madurai Malli, the pride of Madurai and the GI tagged ornamental and a biotherapeutic of the region, stands indeed a floral delight with manifold utility. Despite the vouching of its use in folk medicine and socio-cultural and economic interest, the norms of its field cultivation, production and marketing have not been worked out in greater detail. Notwithstanding to the popularity of this floral crop, there is research gap in understanding the dynamics of harvest. Attempts made to compare the efficacy of PGR treatments in this field study which involves foliar spraying of auxins, cytokinins, gibberellins and salicylic acid show that the flower development and yield can be considered for profitable manipulations. Experiments performed on randomized block design in the month of January-February for a period of two consecutive years indicate that among PGRs, GA and SA can trigger early flowering at higher intensities. Although each of this PGR could exert its own specific influence, salicylic acid treatments provided ample material for scrutiny. Best results of growth and yield could be observed at 100 ppm dosage where the flower production assessed in terms of increases in the number of flowering points, size of the individual flower and the quantum of produce showed an increase. Comparisons show that SA could increase the floral density by stimulating lateral shoots as in BAP and simulated the effects of GA by enhancing the enlargement of calyx and corolla whorls. Observations and results gathered in this investigation assume significance due to the paucity of documented information on this said species. [ABSTRACT FROM AUTHOR]
