Phylogenetic trends in TZ staining analysis of six deep dormancy seeds.
The assessment of seed quality and physiological potential is essential in seed production and crop breeding. In the process of rapid detection of seed viability using tetrazolium (TZ) staining, it is necessary to spend a lot of labour and material resources to explore the pretreatment and staining methods of hard...Peng, Chen Yin ; Wu, Yu ; Huang, Wen Hui ; Deng, Zhi Yun ; Sun, Xiao Rui …

Seed dormancy concepts in orchids: Dendrobium cruentum as a model species.
Generally, orchids produce dust-like seeds in which endosperm reduction and embryo undifferentiation represent a derived state shared with species in about 11 other plant families. Orchid seeds are proposed to have a special kind of morphological or morphophysiological dormancy. We test this proposition, overcoming several design limitations of earlier studies,...Prasongsom, Sasikarn ; Thammasiri, Kanchit ; Pritchard, Hugh W.

Piloting development of species conservation action plans in Guinea.
Conservation action plans need to be devised and implemented if we are to reduce the extinction risk faced by globally threatened plants. However, most plant species categorized as threatened globally on the IUCN Red List lack conservation action plans. In West Africa, Guinea is one of the most diverse countries... -

Seed-coat thickness explains contrasting germination responses to smoke and heat in Leucadendron.
Fire stimulates the germination of most seeds in fire-prone vegetation. Fruits of (Proteaceae) are winged achenes or nutlets that correlate with their requirements for smoke and/or heat in promoting germination. We describe five possible smoke–heat dormancy-release/germination syndromes among plants, of which displays three (no response, smoke only, smoke and heat).... -

Correlated evolution of seed mass and genome size varies among life forms in flowering plants.
Seeds show important variation as plant regenerative units among species, but their evolutionary co-variations with other plant characteristics are still poorly understood. Whilst a positive association of seed mass with genome size (GS) and life forms has already been documented, a broad-scale quantification of their evolutionary correlation and adaptive selection... -

KEW GARDENS AND THE EMERGENCE OF THE SCHOOL MUSEUM IN BRITAIN, 1880–1930
The idea of the school museum as an active resource for object-based learning played an important but now neglected part in programmes of educational reform during the closing decades of the nineteenth century and the opening decades of the twentieth. In this article we focus on the role of the... -

More on seed longevity phenotyping.
Understanding the relative longevity of different seed lots, perhaps of different species or genotypes, but also following production under different environments or using different cultivation methods, or following different post-harvest treatments, is relevant to anyone concerned with the retention of seed lot viability and vigour during storage. However, different scientists...Phenotypes, Orthodox seeds, Seed storage, Plant conservation, p50, Seed traits, and Comparative longevity protocol

Is alcohol a tropical medicine? Scientific understandings of climate, stimulants and bodies in Victorian and Edwardian tropical travel.
This paper offers a new perspective on historical understandings of the relationship between alcohol, climate and the body, by studying the way that British explorers of tropical Africa drank alcohol and wrote about drink between 1850 and 1910. We demonstrate that alcohol was simultaneously classified as a medicinal, a preventative...Armston-Sheret, Edward ; Walker, Kim

Regulation of seed germination by diurnally alternating temperatures in disturbance-adapted banana crop wild relatives (Musa acuminata).
Seed conservation of banana crop wild relatives (Musa L. spp.) is limited because of lack of knowledge about their germination ecology. Musa acuminata Colla, the most important banana crop wild relative, is distributed in tropical and subtropical Asian and Pacific rainforests and colonizes disturbed sites. The role of temperature in...
