“…The positive effect of cold storage results in low ethylene release due to low metabolic activities like respiration, transpiration and maintains high humidity under wet condition. Similar results were observed by Pun et al, (2005) in spray carnation, Ichimura et al, (2009) in cut eustoma, delphinium and snapdragon and Muchui (2012) in banana.…”

“…The ACO activity was measured according to Vriezen et al (1999) and Pun et al (2005) with slight modifications. One gram each of petals or gynoecia were powdered using liquid nitrogen and extracted with extraction buffer that contained 200 mM Tris and 20% glycerol (pH 7.5 at 4°C), 30 mM isoascorbic acid sodium salt and 5 mM DTT.…”

Depression of enzyme activities and gene expression of ACC synthase and ACC oxidase in cut carnation flowers under high-temperature conditions

High-temperature depression of ethylene production in cut carnation flowers cv. 'Excerea' can occur because of inhibition of ACC synthase (ACS) and ACC oxidase (ACO) activities in flowers. Large differences were apparent between ACS activity in petals at 24°C and 32°C. These ACC-accumulationrelated activities were markedly decreased in petals at 32°C, indicating that a low ACS activity and ACC accumulation in petals are a factor of ethylene biosynthesis inhibition under high-temperature conditions. In addition, the respective expressions of DC-ACO1 and DC-ACS1 were low in both gynoecia and petals of flowers kept at 32°C. Results indicate that low ACS and ACO activities under high-temperature conditions were transcriptionally regulated.

“…In the former, sugars seem to delay petal senescence by reducing ethylene sensitivity [6,7,8,9]. In contrast, it has been suggested that in ethylene-insensitive flowers sugars might prevent a decline in osmotic pressure and delay celldeath [10].…”

Senescence is a key process determining the life interval of several cut flowers and sugars added to the nutrient are known to increase vase life in several flowers, very little is known about endogenous variations in glucopyranosyl levels in several floral tissues, predominantly beyond petals, during natural flower development. In present study, we had evaluated the glucopyranosyl efficiency at different concentrations and different time intervals. We had found that the efficiency of glucopyranosyl slightly affect the senescence approaches and played a significant role in inhibition of senescence. Furthermore, it also played a key role on increasing the cells size and enlargement of cells at growing stages of petals. Further we had randomly investigated the content of sucrose in treated petals and control. Interestingly we had found increasing amount of sucrose in treated petals compare to that of untreated. Sucrose contents increased with flower development reaching 50% to 74% higher levels at later stage compared to that of early stagein excised petals.
