Effect of different packing and storage conditions on biochemical parameters in extending the vase life of cut carnation cv. Kiro

An experiment was carried out to study the effect of different packing and storage conditions on vase life of cut carnation cv. Kiro. The flowers packed in polypropylene at 5°C cold storage under wet condition recorded significantly highest total chlorophyll content of leaf (78.98 SPAD unit), highest total chlorophyll content of calyx (38.00 SPAD unit) and lowest ethylene estimation (0.27 ppm/h) which have extended the vase life period of carnation flower cv. Kiro.

Kiro.10 August 2018Introduction Post-harvest life of cut flowers also depends upon efficient packaging and storage.Carnation (Dianthus caryophyllus L.) belongs Appropriate packaging of cut flowers togetherto the family caryophyllaceae and native to with pulsing are helpful to ensure fresh qualityMediterranean region. Carnation is one among of flowers. Packing is a tool for controllingthe top five cut flowers in the world and in flower quality in the distribution chain. ApartIndia (Singh, 2006). The beauty of the cut from preventing mechanical damage, theflowers lies with the freshness of the flowers package serves as a barrier between thefor longer time without post-harvest losses. conditions inside and outside the package. It protects the flowers from unfavorable outsideIt is claimed that 70 per cent of the potential conditions and enables a micro-climate toquality of cut flowers is pre-determined at develop inside the package (Lavanya et al.,harvest, whereas the remaining 30 per cent is 2016).
