Seed vigour and crop establishment: extending performance beyond adaptation.

Seeds are central to crop production, human nutrition, and food security. A key component of the performance of crop seeds is the complex trait of seed vigour. Crop yield and resource use efficiency depend on successful plant establishment in the field, and it is the vigour of seeds that defines their ability to germinate and establish seedlings rapidly, uniformly, and robustly across diverse e...

Canola Seed Vigour Ethanol Test

Seed germination, seedling emergence and crop establishment are important aspects of canola production, and are the main components of seed/seedling vigour. A major concern of seed businesses and canola growers alike is loss of seed vigour that may go undetected before planting. Two vigour assays, based on off-gassing of ethyl alcohol from poor vigour seed, are being developed. They are a simpl...

Influence of seed colour on seed vigour in Brassica napus

Yellow seed colour in Brassica napus is a desired trait and has a strong impact on the quality of Canola and the processed products from the seed. The trait is accompanied with a thinner seed coat when compared to black seeds. For the model plant Arabidopsis thaliana, different mutants have been characterised showing the transparent testa phenotype to be associated with light seed colour due to...

Malaria, Adaptation and Crop Choice

This paper investigates how rural farm households adapt to the risk of disease. In the context of malaria, adaptation brings to mind mosquito nets, sprays and coils. However, adaptation may be more subtle. For instance, households living in malaria-endemic regions may alter their crop choice to reduce their exposure to disease and the associated likelihood of crop failure. Thus the risk of mala...

Extending Stechkin’s Theorem and Beyond

Let K ⊂ Rd be a closed set and pK the nearest point mapping, which associates with every point x ∈ Rd the set of all points in K closest to x. It is well known that pK is single-valued a.e. The topological counterpart was provided by Stechkin [6] in 1963, who proved that pK is single-valued at most points of Rd, that is, the set of points at which pK is not single-valued is of the first Baire c...
