  1. Stimulation of Bud Production in <em>Eucalyptus globulus</em> by Paclobutrazol Application

    Item type: Journal Article • Journal: South African Forestry Journal
    Trunk injection of paclobutrazol (Clipper) significantly increased the bud crop on 7-year-old Eucalyptus globulus (Labill.) seed orchard trees, within one year of application. This is the first reported stimulation of reproduction to occur, with eucalypts, in the season of application...
  2. Growth patterns of Italian ryegrass cultivars established in different seasons

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    A comparison is made between various Italian ryegrass cultivars established under irrigation on a well‐drained upland site during the traditional autumn months, with plantings of the same cultivars at other times of the year.
  3. The influence of nitrogen fertilization, spring burning and height of stubble on hay and seed production of <em>eragrostis curvula</em> <sup>1</sup>

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    This investigation, conducted over a three‐year period, emphasized the strong effect of nitrogen fertilization on both hay and seed production. The optimum level of nitrogen, for conditions on the Eastern Highveld being 100–150 kg N/ha applied in spring, followed by...
  4. Forage potential of Japanese radish (<em>Raphanus sativus</em>) as influenced by planting date and cultivar choice

    Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa
    Japanese radish shows potential as a winter forage. If planted early (Dec/Jan.), high temperatures can damage seedlings. With late plantings (Mar./Apr.), the growing season can become a limiting factor. A study to establish the optimum planting date for warmer areas...
  5. Influence of temperature and daylength on the phenological development of annual <em>Medicago</em> species with particular reference to <em>M. truncatula</em>, cv. Jemalong

    Influence of temperature and daylength on the phenological development of annual <em>Medicago</em> species with particular reference to <em>M. truncatula</em>, cv. Jemalong

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    In a glasshouse and two growth-room trials, carried out in conjunction with 12 serial plantings in pots in the open, it was found that the phenological development of Medicago truncatula, M. tornata, M. aculeata, M. polymorpha, M. scutellata and M...
  6. The influence of photoperiod and temperature on the pre-flowering phase length of eleven soybean cultivars in northern Natal

    The influence of photoperiod and temperature on the pre-flowering phase length of eleven soybean cultivars in northern Natal

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The effect of photoperiod and temperature on the pre-flowering phase length of 11 soybean cultivars was studied. Heat units (10 to 30°C) and night hours (sunset to sunrise) were used as measures of temperature and photoperiod respectively. Highly significant negative...
  7. Effect of a foliar application of paclobutrazol in autumn on the reproductive development of ‘Songold’ plum

    Effect of a foliar application of paclobutrazol in autumn on the reproductive development of ‘Songold’ plum

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A foliar application of paclobutrazol (1- (4-chlorophenyl) −4,4-dimethyl-2- (1,2,4- triazol-1-yl) pentan-3-ol) at 250 or 500 mg dm−3 a.i. in autumn, or late winter applications of dinitro-o-cresol oil emulsion (DNOC) in water at 3% v/v, increased the percentage of ‘Songold’ plum...
  8. Bepaling van optimale blom en plantdatums vir koring in die sentrale besproeiingsgebiede van die RSA met behulp van 'n groeimodel

    Bepaling van optimale blom en plantdatums vir koring in die sentrale besproeiingsgebiede van die RSA met behulp van 'n groeimodel

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Optimale blom- en plantperiodes vir besproeiingskoring is bepaal vir 15 lokaliteite in die sentrale besproeiingsgebiede van die RSA deur gebruik te maak van historiese temperatuurdata en die PUTU koringgroeimodel. Die hoogste gemiddelde opbrengs is gesimuleer met blomperiodes wat oor die...
  9. Low temperature treatment advances flowering in <em>Clivia miniata</em> (Lindley) Regel

    Low temperature treatment advances flowering in <em>Clivia miniata</em> (Lindley) Regel

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Clivia miniata plants were exposed to a cold treatment of 7.5–10 °C for 14 days in the dark from 24 April 2000. Compared to the non-cold treated control plants, the cold-treated plants started flowering four weeks earlier resulting in 80%...
