Native Australian Acacias: Unrealised Ornamental Potential

Ratnayake, Kamani; Joyce, Daryl (International Society for Horticultural Science, 2010)

cacia , commonly known as wattle, is the largest genus of flowering plants in Australia. Over 950 species have been identified on the continent, constituting mor e than half of the 1352 species found worldwide (Maslin, ...

Copper distribution and ionic form effects for postharvest treatments of cut Acacia holosericea stems

Ratnayake, Kamani; Bui, Chuc L.; Joyce, Daryl C. (Elsevier, 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 ...
Treatment with Cu2+ ions extends the longevity of cut Acacia holosericea foliage stems

RATNAYAKE, K.; JOYCE, D. C.; WEARING, A. H. (2011)

Wilting associated with diminishing post-harvest water uptake is a major constraint on longevity for cut stems of many Acacia spp. Cu2+ ions have known biocidal activity and may also act as inhibitors of plant wound ...
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

Ratnayake, K.; Joyce, D.C.; Webb, R.I. (Elsevier, 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 ...
Investigation of potential antibacterial action for postharvest copper treatments of cut Acacia holosericea

Ratnayake, K.; Joyce, D.C.; Webb, R.I. (Elsevier, 2012)

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

Effects of three different nano-silver formulations on cut Acacia holosericea vase life

Liu, Jiping; Ratnayake, Kamani; Joyce, Daryl C.; He, Shenggen; Zhang, Zhaoqi (Elsevier, 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 ...
