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 ...
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 ...
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 ...
