The set of technology characteristic-related variables includes farmer's perception about the maturity period of the crop (MATC), higher productivity characteristic (PRDTYC), and the availability of seeds at a cheaper price (CHEPSC).
But the speed of change depends on the frequency and intensity of disturbance, and the availability of seed parents.
European competition regulators also said publicly, before a Bayer-Monsanto deal was even signed, that they would look at how it could affect prices and the availability of seed products, as well as research.
Having come to Duke more than a decade ago to do research at the Lemur Center, Christine Drea, the Earl D. McLean Professor of Evolutionary Anthropology, said the improvement in facilities and the availability of seed funding for pilot research projects have been keys to her success.
Egyptian populations were only included for one of the treatments measuring ecological fitness correlates (nitrogen gradient) as all experimental procedures were terminated prior to plants flowering (seeding stage) and limited availability of seed stock.
The availability of seeds and invertebrates on uncropped margins is strongly influenced by management, particularly cutting, cultivation and herbicide use.
Yet, current DGVMs assume ubiquitous availability of seeds and do not consider any seed dispersal mechanisms and/or plant migration process, which may influence the assessment of impacts to the ecosystem that rely on the vegetation structure changes (i.e., change in albedo, runoff, and terrestrial carbon sequestration capacity).
Major constraints to quinoa cultivation are the availability of seeds and most importantly the lack of technical know-how, whereas marketing and utilization of the Quinoa crop as a food crop are challenged by its unfamiliarity.
Depending on the need for cells and availability of cells, flasks were seeded with 6 to 10 million cells, with 50 ml of medium, and incubated at 37°C, in an atmosphere of 5% CO2.
