  1. Response of five soybean (<em>Glycine max</em> (L.) Merr.) cultivars to lime and phosphorus on an acid Normandien subsoil

    Response of five soybean (<em>Glycine max</em> (L.) Merr.) cultivars to lime and phosphorus on an acid Normandien subsoil

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Five soybean cultivars (Hill, Geduld, Forrest, Welkom and Oribi), previously selected for Al tolerance or sensitivity by a rapid seedling evaluation method, were grown in acid soil treated with varying rates of lime and P. After 35 days the plants...
  2. Assessment of aluminium tolerance in maize using a rapid screening procedure

    Assessment of aluminium tolerance in maize using a rapid screening procedure

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Routine testing for Al tolerance requires that screening procedures be both rapid and simple. Growth-chamber techniques, developed in the USA, show considerable promise in this regard and were used in this study to compare the Al tolerance of 10 maize...
  3. Genotypic tolerance of selected dry bean (<em>Phaseolus vulgaris</em> L.) cultivar s to soluble Al and to acid, low P soil conditions

    Genotypic tolerance of selected dry bean (<em>Phaseolus vulgaris</em> L.) cultivar s to soluble Al and to acid, low P soil conditions

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Twelve dry bean cultivare were grown for seven days on filter paper soaked with nutrient solution containing a range of up to 10 mmol Al dm−3. Differential response to Al toxicity, measured as taproot elongation, occurred at Al concentrations of...
  4. Reduced leaf diffusive resistance with re-exposure of maize (<em>Zea mays</em> L.) to atrazine

    Reduced leaf diffusive resistance with re-exposure of maize (<em>Zea mays</em> L.) to atrazine

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Application and subsequent removal of atrazine in a nutrient solution resulted in changes in leaf diffusive resistance in maize. Re-exposure to atrazine elicited lower responses in leaf diffusive resistance, suggesting an improved tolerance to atrazine by maize. The time elapsed...
  5. A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    A field evaluation of the differential tolerance to soil acidity of forty-eight South African maize cultivars

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    A field experiment was conducted on a Normandien clay loam (Plinthic Paleudult) to compare the acid tolerance of 48 commercially grown maize (Zea mays L.) cultivars. Cultivars were compared in terms of grain yield, plant height and leaf Al content...
  6. Preliminary studies on the inheritance of atrazine tolerance in maize (<em>Zea mays</em> L.)

    Preliminary studies on the inheritance of atrazine tolerance in maize (<em>Zea mays</em> L.)

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Thirty-three maize (Zea mays L.) inbreds were screened for tolerance to atrazine (2-chloro-4-ethylamino-6- isopropylamino-1,3,5-triazine) in a glasshouse using a sand culture technique. Tolerance ranged from 95,7–51,0% of the control. The continuous pattern of tolerance exhibited by the inbreds indicated polygenic...
  7. Relationship between DIMBOA content and atrazine tolerance in maize

    Relationship between DIMBOA content and atrazine tolerance in maize

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Data of two independent studies are presented to illustrate the relationship between DIMBOA content of maize inbreds and their tolerance to atrazine. Polynomial regression curves best described this relationship. R-squared values of 0,48 and 0,87 between DIMBOA content and tolerance...
  8. 'n Vergelyking van koringkultivars ten opsigte van droogteverdraagsaamheid

    'n Vergelyking van koringkultivars ten opsigte van droogteverdraagsaamheid

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    'n Proef met vyf koringkultivars en twee vogpeile (50 en 80% van veldwaterkapasiteit) is in 'n glashuis uitgevoer. Kultivarverskiile in droëmateriaalakkumulasie is verkry by die lae vogpeil. Gamtoos het die grootste blaaroppervlakte en blaarmassa gehad by die vlagblaarstadium en uiteindelik...
  9. Performance of five soybean cultivars in relation to lime and phosphorus levels on an acid Ultisol

    Performance of five soybean cultivars in relation to lime and phosphorus levels on an acid Ultisol

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The seed-yield response of five soybean cultivars (Hill, Geduld, Forrest, Welkom and Oribi) to applications of lime [Ca(OH)2] and P was evaluated over two seasons in the field on an acid soil of the Normandien series (Plinthic Paleudult). As a...
  10. Tolerance of almond (<em>Prunus amygdalus</em>) and peach (<em>P. Persica</em>) seedlings to metam-sodium

    Tolerance of almond (<em>Prunus amygdalus</em>) and peach (<em>P. Persica</em>) seedlings to metam-sodium

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    The tolerance of 1-year-old almond seedlings (Prunus amygdalus) in a loamy sand, and newly planted peach seedlings (P. persica) in washed river sand to low concentrations of metam-sodium (sodium methyldithiocar- bamate) in the root zone was investigated. Phytotoxic symptoms were...
