    High-density orchards improve the quality of ‘Songold’ plums from lower, more shaded canopy positions

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Gel breakdown is a major postharvest problem in ‘Songold’ plums (Prunus salicina Lindl.) that is exacerbated in fruit harvested from lower canopy positions in large trees. Modern high-density orchards with small trees aggressively address this problem through improved light distribution...
  3. Determining sample size for assessing species composition in grassland<sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Species composition is measured in grasslands for a variety of reasons. Commonly, observations are made using the wheel‐point apparatus. However, the problem of determining optimum sample size has not yet been satisfactorily resolved. In this study the wheel‐point apparatus was...
