Antioxidant Capacity of Indigenous Root and Tuber Crops of Sri Lanka as Affected by Simple Processing

Poojanee Rupasingha; Kamani Ratnayake; Anoma Senarathne (Asian Food Science Journal, 2020-11)

With a view to establish their nutritional importance and promote consumption and industry usage, this study determined the contents of selected bio active compounds and antioxidant properties in 15 root and tuber crops ...
Characterisation of xylem conduits and their possible role in limiting the vase life of cut Acacia holosericea (Mimosaceae) foliage stems

Jilushi W. Damunupola; Kamani Ratnayake; Daryl C. Joyce; Donald E. Irving (Functional Plant Biology, 2011)

Early desiccation limits the vase life of Acacia cut flowers and foliage and may be attributable to poor hydraulic conductivity (Kh) of the cut stems. Acacia holosericea A.Cunn. ex G.Don has been adopted as the test species ...
A convenient sample preparation protocol for scanning electron microscope examination of xylem-occluding bacterial biofilm on cut flowers and foliage

Kamani Ratnayake; Daryl C. Joyce; Richard I. Webb (Scientia Horticulturae, 2012)

Microbes and their exopolysaccharides (EPS) can block xylem vessels, thereby increasing the hydraulic resistance and decreasing the vase life of cut flowers and foliage. Scanning electron microscopy (SEM) provides a ...
Copper distribution and ionic form effects for postharvest treatments of cut Acacia holosericea stems

Kamani Ratnayake; Chuc L. Bui; Daryl C. Joyce (Scientia Horticulturae, 2011)

A short postharvest life is the major constraint associated with cut Acacia flowers and foliage. Treatment with CuSO4 (Cu2+) has previously been shown to improve the longevity of cut Acacia holosericea stems. Towards ...
Cu2+ inhibition of gel secretion in the xylem and its potential implications for water uptake of cut Acacia holosericea stems

Kamani Ratnayake; Daryl C. Joyce; Richard I. Webb (Scandinavian Plant Physiology Society, 2013)

Maintaining a high rate of water uptake is crucial for maximum longevity of cut stems. Physiological gel/tylosis formation decreases water transport efficiency in the xylem. The primary mechanism of action for ...
Effects of three different nano-silver formulations on cut Acacia holosericea vase life

Jiping Liu; Kamani Ratnayake; Daryl C. Joyce; Shenggen He; Zhaoqi Zhang (Postharvest Biology and Technology, 2012)

The relative efficacies of three chemically different nano-silver (NS) formulations were evaluated for their potential to extend the vase life of short-lived cut Acacia holosericea foliage. The novel proprietary formulations ...
Investigation of potential antibacterial action for postharvest copper treatments of cut Acacia holosericea

Kamani Ratnayake; Daryl C. Joyce; Richard I. Webb (Postharvest Biology and Technology, 2012-04-07)

The mechanisms of action of Cu2+ in improving the longevity of cut flowers and foliage have not been elu cidated. Possible antimicrobial action of Cu2+ against stem end and vase solution colonising bacteria was investigated ...
