Role of surfactants in foliar uptake of plant growth regulators

Creator:

Tan, Siyuan

Abstract:

Penetration of ¹⁴C-labeled plant growth regulators into the surface of apple (Malus pumila M.) leaves pre-soaked in 10 ml I⁻¹ solutions of surfactant was measured by detecting changes in radioactivity of the solution in glass cylinders sealed to the astomatal, adaxial surface of the leaf discs. Penetration of 2,4-D [(2,4-dichlorophenoxy)acetic...

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,...
