EFFECT OF CERTAIN CHEMICAL PRESERVATIVE SOLUTIONS ON VASE LIFE AND POSTHARVEST CHARACTERISTICS OF CARNATION Dianthus caryophyllus cv. Felice CUT FLOWERS
Year: 2014
Type: article
Abstract: This experiment was carried out in the laboratory of Ornamental Plants and Woody Trees Department at the National Research Center, Dokki, Giza, Egypt, during two successive seasons (2008 and 2009) to investigate the effect of some chemical preservative solutions such as 8hydroxyquinoline sulphate (8-HQS) alone or with sucrose or benzyl adenine (BA), or gibberellic acid (GA 3 )), citric acid, alone or with sucrose and silver thiosulphate (STS) alone or with sucrose.Also, aluminum sulphate [Al 2 (SO 4 ) 3 ] alone or with BA or GA 3 , in addition to the control (distilled water) on vase life.and maximum increase in fresh weight i.e as keeping quality and change in fresh weight and water balance of carnation Dianthus caryophyllus cv."Felice" cut flowers.Using solution of (300 ppm 8-HQS+40g/l sucrose) and (0.4mM STS +50 g/l sucrose) significantly increased vase life and maximum increase in fresh weight compared with control (distilled water).Pulsing carnation cut flowers in 50 ppm GA 3 for 24h.then placed in 200 ppm Al 2 (SO 4 ) 3 showed the highest values of increase in fresh weight % after 12 days in the 2 nd season (12.63%).The highest level of water balance was recorded at 12 th days by using 50 ppm of GA 3 for 24 h.then placed in Al 2 (SO 4 ) 3 in the 2 nd season.
