Abstract: An investigation was carried out to study the effect of polyamines viz., spermine, spermidine, putrescine and salicylic acid and α-lipoic acid on postharvest physiology and vase life of gerbera. Chemicals were applied in the form of vase solution @ 10 and 20 ppm each. Among all the treatments, gerbera cut flowers treated with spermine @ 10 ppm showed maximum retention of flower fresh weight (38.01, 38.15, 24.27 and 21.88 g), total soluble sugars (34.95, 38.78, 41.15 and 33.72 mg/g), protein content (23.09, 26.00, 27.26 and 17.29 mg/g) and minimum electrolytic leakage (19.19, 26.26, 33.21 and 43.07 %) in the petal tissue which was at par with salicylic acid @ 20 ppm as recorded on 4th, 8th, 12th and 14th day of vase life. Further, phenols in the petal tissue (3.00, 2.62, 2.42 and 2.08 mg/g) were recorded higher with salicylic acid @ 20 ppm and followed by spermine @ 10 ppm. Anthocyanin content in the petal tissue (17.38 mg/g) and lignin content (6.55 %) in the stalk of gerbera were maximum with the vase solution treatment of spermine @ 10 ppm and followed by salicylic acid @ 20 ppm. Gerbera cut flowers treated with spermine @ 10 ppm showed enhanced vase life (16.92 days), which was at par with salicylic acid @ 20 ppm (16.50 days) as compared to control (12.08 days). Thus, the treatments of spermine @ 10 ppm and salicylic acid @ 20 ppm influenced the postharvest physiology of gerbera flowers and extended the vase life of gerbera by 4-5 days as compared to control.
