Bougainvillea Bract, Chlorophyll Fluorescence, Anthocyanin and Antioxidant Development as Affected by AOA, Sucrose and Phloem Cut

A.B.M. Sharif Hossain and Musamma M. Uddin

Abstract:
Background and Objective: Bougainvillea is an evergreen plant and blooms all the year round. Bougainvillea has decorated value in office, home, yard and medicinal values as the treatment of cough. The flowers and stems are dried, boil in water and drink as tea. The study was carried out to investigate the effects of amino oxyacetic acid (AOA), sucrose and phloem tissue cut stress, on the bract size, pigments, antioxidant, flavonoid and physico-biochemical parameters of Bougainvillea bract. Materials and Methods: The treatments were of the phloem cut stress in the bark of one year shoot, 100 ppm AOA and 3% sucrose concentration and water control employing swabbing technique. Results: The floral bract number was higher in the 15th week in phloem cut stress and 3% sucrose treated bract than in water control and AOA treated bract. Moreover, the size of the bract, weight and longevity were the highest in the physiological stress treated bract. However, it had been shown that the Fo, Fm, Fv and quantum or photo-synthetic yield (Fv/Fm) were found higher in phloem cut stress and 3% sucrose treated bract than in other two treatments. The highest chlorophyll (a and b) and carotene content was recorded in the phloem cut stress treated bract. The anthocyanin, total phenol, total flavonoid and DPPH radical scavenging activity increased in all treated bract compared to the control bract. However, the highest anti-oxidant was found in the phloem cut stress treated bract. Conclusion: Finally it seemed that phloem cut stress and 3% sucrose were the effective treatment compared to the AOA and water control.
