Physiological Changes during Postharvest Senescence of Broccoli 1565 Physiological Changes during Postharvest Senescence of Broccoli1
The objective of this work was to determine the early physiological changes throughout shelf life of fresh broccoli (Brassica oleracea L. var. italica) cv. Piracicaba Precoce at 25oC and relative humidity of 96% in the dark until complete senescence. Head inflorescences showed lack of turgidity and commercial value when weight loss reached up to 5%, coinciding with 48 hour after harvest. Chloro...
متن کاملPhysiological changes accompanying senescence in the ephemeral daylily flower.
The daylily flower, Hemerocallis hybrid cv Cradle Song, develops from the opening bud to full senescence in 36 hours. Unlike other ephemeral flowers studied to date, it does not respond to ethylene, but other senescence phenomena are similar. There was a small respiration climacteric coinciding with early flower senescence, and it was also observed in isolated petals and petal slices. Cyclohexi...
متن کاملHot air treatment delays senescence and maintains quality of fresh-cut broccoli florets during refrigerated storage
A postharvest treatment with hot air (48 C during 3 h) was applied to fresh-cut broccoli to investigate its effect on quality and senescence during storage at 0 C. The treatment delayed yellowing as evidenced by lower decrease of Hue values during storage. After 21 days of storage, treated broccoli had chlorophyll content approximately 40% higher than controls. The treatment did not affect eith...
متن کاملChanges in Physicochemical Properties of Wild and Cultivated Blackberry during Postharvest Cold Storage
Background: Blackberry is a seasonal harvested fruit that is also very fragile and perishes quickly. A comparative study was conducted to find out influence of cold storage on physicochemical parameters of wild and cultivated blackberry over a period of 12 days. Methods: The plant materials were composed of the blackberry fruit, including a compound of cultivated blackberry (Rubus spp.), and w...
متن کاملDelaying of Postharvest Senescence of Lisianthus Cut Flowers by Salicylic Acid Treatment
Salicylic acid (SA) is considered to be plant signal molecule that plays a key role in plant growth, development, and defense responses. The physiological mechanism of exogenous SA to affect the senescence of cut lisianthus flowers during vase life was investigated. Fresh cut lisianthus flowers were treated with distilled water (control), 0.5, 1 and 2 mM SA and then held at 25◦C up to 12 days. ...
