The amount of particular crops offered for price-support loans has varied greatly from year to year, as have redemptions.
Previously, if you wanted an aperture anywhere near that f2 mark, you'd have had to get separate glass for each; Sigma previously offered wide zooms for crop sensor (APS-C) format digital SLRs, but this one does the job for full-frame cameras like Canon's 5D range, too.
It also offers an opportunity for crop metabolic engineering employing synthetic trans-acting siRNAs (syn-tasiRNAs).
Raspberries, sadly, offered a meagre crop.
The C4 plants which have CO2 concentrating mechanism within their leaves have very much reduced levels of photorespiration and thus have evolved to thrive in hot, arid environments and offer valuable insights for crop improvement strategies.
Genetically modified plants expressing insecticidal traits offer a new strategy for crop protection, but at the same time present a challenge in terms of food safety assessment.
For such long-lived and vegetatively propagated crops with complex genetic and reproductive characteristics as fruit trees, genetic modification offers an important potential for crop improvement.
Other sites — like Aviary.com, Pixlr.com, Splashup.com, and Citrify.com — are competing to offer simple tools for cropping an image, fixing red eye or making other tweaks to an image.
Expansion of cultivation area is an increasingly unlikely and costly solution [ 2] and though gains can be achieved through improved agronomic management [ 3], current advances in genetics and genomics offer many opportunities not only for crop genetic research but also technology assisted cultivar development.
Production of a new, stable and fertile allohexaploid Brassica crop species through genomic breeding, bringing together all the genetic diversity of the cultivated Brassica species and concentrating allelic heterosis, offers a pathway of significant interest for crop geneticists.
