  • The free radical scavenging system in overcoming phytotoxicity and breaking dormancy

    Creator:
    Zhen, Liping
    Abstract:
    Hydrogen cyanamide (CY) induced earlier budbreak, more uniform and a higher percentage of budbreak in resting poplar (Populus alba x P. gradidentata, NC 5339) plants. However, it was phytotoxic to poplar when applied at 0.5 M or higher concentrations. Percent budbreak increased and percent dieback decreased when poplar plants were...

  • Nitrogen partitioning and remobilization in field-grown apple trees

    Creator:
    Khemira, Habib
    Abstract:
    Uptake and cycling of nitrogen (N) in mature trees are not well understood. Fertilizer-N uptake, partitioning, and use-efficiency were studied in standard strain 'Topred Delicious' and spur strain 'Redspur Delicious' mature apple trees {Malus domestica Borck) on 'Malling 7A' (M.7A) rootstocks. The treatments consisted of a ground application in spring,...
