Influence of temperature and growth stage on the diurnal fluctuation in the non‐structural carbohydrate content of kikuyu (Pennisetum clandestinum Hochst)
Item type: Journal Article • Journal: Journal of the Grassland Society of Southern Africa • Authors: J.P. Marais --- , Republic of South Africa D.L. Figenschou --- , Republic of South AfricaThe non‐structural carbohydrates of kikuyu (Pennisetum clandestinum Hochst) seem to consist mainly of sucrose. Total non‐structural carbohydrate content increased rapidly during the morning and reached maximum concentration in the afternoon. After sunset, the concentration decreased rapidly, reaching a minimum level... -
Sucrose synthesis and translocation in Zea mays L. during early growth, when subjected to N and K deficiency
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: J.C. Pretorius --- Department of Agronomy and Horticulture, Republic of South Africa D.T. Nieuwoudt --- Department of Agronomy and Horticulture, Republic of South Africa Diana Eksteen --- Department of Agronomy and Horticulture, Republic of South AfricaBy omitting N and K either separately or in combination from the rooting medium, a nutrient stress condition was created with the aim of ascertaining whether sucrose synthesis or its translocation was linked to nutrient availability (N, K) in young... -
Preliminary investigation on the potential of Clivia miniata Regel as a cut flower
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: P.J. Robbertse --- Department of Plant Production and Soil Science, Republic of South Africa C.B. Honiball --- Department of Plant Production and Soil Science, Republic of South AfricaClivia miniata Regel is widely cultivated as a garden ornamental and a pot plant. It occurs in many attractive shades of orange, red, yellow and pink but little information exists regarding its use as a cut flower. The possibility of... -
Differences in the level of D-glucose and sucrose among durum wheat (Triticum turgidum var durum L.) genotypes differing in their responses to drought stress
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: K.F. Solomon --- Department of Plant Sciences, South Africa M.T. Labuschagne --- Department of Plant Sciences, South AfricaThe effect of drought stress on the content of water soluble carbohydrate (sucrose and D-glucose) was investigated in durum wheat (Triticum turgidum var durum L.) above ground organs to assess and characterise the responses of genotypes with differing responses to... -
Maize grain soluble sugar and protein contents in response to simulated hail damage
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Silindile P Miya --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South Africa Albert T Modi --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South Africa Samson Z Tesfay --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South Africa Tafadzwanashe Mabhaudhi --- Crop Science, School of Agricultural, Earth and Environmental Sciences, South AfricaProduction of grain of high nutritional quality is essential in maize (Zea mays L.) as a food grain crop. Grain quality may be influenced by environmental and management factors, such as hail, plant density and grain selection. A study was... -
The short-term effects of surface-applied dolomitic lime and gypsum on soil chemical properties and yields of sugarcane ratoon crops in KwaZulu-Natal, South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Sandile Siphesihle Mthimkhulu --- , South Africa Dimpho Elvis Elephant --- , South Africa Neil Miles --- , South Africa Louis William Titshall --- , South AfricaThis study investigated the effects of surface-application of lime and gypsum on soil properties and yields of ratoon sugarcane crops. Treatments involved once-off surface application of dolomitic lime (L), gypsum (G) and dolomitic lime plus gypsum (LG) in factorial combination,...
