The germination requirements of 19 herbs in the Australian Alps were investigated to determine which species may be sensitive predicted climate changes. Seeds subjected factorial treatments cold stratification for 0, 4, 8 and 12 weeks, followed by incubation at constant temperatures 10, 15, 20 25 °C alternating 20/5 20/10 °C. Germination responses used identify stratification-dependent species, classify dormancy optimum conditions laboratory germination. Ordinal logistic regression was...
Societal Impact Statement Conservation seed banks maintain collections of many seed‐bearing plant species, providing germplasm and data to support management wild populations. However, a proportion species produce seeds that are difficult collect, dry, store utilise; these known as ‘exceptional’ species. Here we tested framework for identifying exceptional document examples provide case studies within the Australian flora. We present workflow may be used identify additional direct efforts...
Context Fifty per cent of Australian rainforest species produce orthodox seeds, but little is known about their longevity in storage. Aims To (1) estimate the seeds 33 using artificial aging; (2) assess influence habit, habitat range (restricted to or more broadly distributed), seed characteristics (endospermy, dry weight), and collection environment (e.g. precipitation, elevation average temperature) on longevity; (3) compare previously assessed from non-rainforest habitats; (4) aging...
SummaryThe relationship between chronic or long-term photoinhibition, pigment changes, and bract browning in ‘Fire Brimstone’, ‘Olympic Flame’ ‘Wirrimbirra White’ waratahs [Telopea speciosissima (Smith) R.Br.] was investigated. Plants were grown under full sun, 50% shade-cloth over 2 years, with photoinhibition changes measured the bracts leaves at three stages of floral development (tight bud, juvenile open mature flower). Photoinhibition waratah reduced by shading when applied either from...
The potential for indigenous species to establish outside their natural range and become weeds is less well recognised than the exotic weeds. In this study, weed of a native Australian legume, Swainsona sejuncta Joy Thomps., was assessed using risk assessment protocols (the 'Pheloung system') germination experiments. Pheloung system uncovered several traits indicating that S.�sejuncta has significant potential. These include production toxin swainsonine, short generative time, large numbers...
Context Knowledge of seed biology is imperative for effective curation and utilisation seeds. Aims We studied the reproduction Geijera parviflora, a species suitable ecological restoration ornamental horticulture that has largely been overlooked because issues with unreliable germination viability. Methods Germination in response to dormancy-breaking treatments soil burial, variation at an inter-population level were assessed G. parviflora. Seed storability conventional seedbank was tested....
