Changes in the Potential Difference Across Membranes and Ultrastructure of Gladiolus Flowers Preserved in Water at Room Temperature

Influence of postharvest treatments on quality and shelf life of flowers of Jasminum sambac cv. Gundumalli

“…This might be due to treatment of boric acid is an antisense agent. Burzo et al (1998) [4] reported that the brown colouration and loss of fragrance might be due to the accumulation of flavins and other phenolic substances in flower cell vacuoles. The phenol accumulation was also found to be minimum with normal colour retention and fragrance in the packed flowers than the control In agreement with the present finding, the potential of boric acid in prolonging the postharvest life of flowers has been reported earlier in jasmine by (Mukhopadhyay et.al 1980, Binisundar, 2011, Jawaharlal et.al 2012, Manimaran et.al, 2018) [10,6,9] in crossandra by Bhattacharjee, (2002) [2] , in carnation by Serrano et al, (2006) [16] .…”

Gladiolus Scabridus - The Road to Conservation and Commercialization

“…Captain Busch, the pattern was found to be non-climacteric. Burzo et al (1989) found that the CO 2 evolution of Gladiolus florets decreased after 3 days postharvest with the respiration intensity of open florets lower than that of the buds. This evolution pattern of CO 2 from G. scabridus florets needs to be considered with regard to postharvest storage of the spikes.…”

Enhancing shelf life and freshness retention in jasmine flowers (Jasminum multiflorum L.) through Post-harvest chemical treatments

“…(1988) [2] , the brown coloration in flower cell vacuoles is caused by the buildup of flavins and other phenolic compounds. According to Mohansundari et al (2018) [17] , the oxidation of phenolic substances by the polyphenol oxidase enzyme results in enzymatic discoloration that browns the petals.…”

“…The resultant browning in anthorium cut flower spathe affects its marketability causing economic losses. The brown colouration was due to the accumulation of complexes resulting from the polymerization of flavins and other phenolic substances in the cell vacuoles (Burzo et al 1988) [2] . Nirmala and Reddy (1992) [19] reported that, in the presence of O2, the enzyme polyphenol oxidase might oxidise these compounds to quinones which simultaneously polymerised into brown pigment.…”
