  • Modeling phyllochron in wheat and barley

    Creator:
    Cao, Weixing
    Abstract:
    An understanding of the effect of environment on phyllochron (degree-days between two successive leaves) is necessary to model cereal crop canopy growth. This study was designed to investigate the relationships of phyllochron to temperatures and daylengths in winter wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.). A series...

  • Effects of growth retardant and nitrogen level on growth, development and yield of Yamhill wheat

    Creator:
    Nounamo, Laurent
    Abstract:
    Increases in wheat production due to breeding may be reaching a plateau. The application of N-fertilizer beyond optimum levels leads to lodging and to an increase in tiller death. The use of plant growth regulators (retardants) may be an answer for future increases in production. Experiments were conducted in 1983...
