Low temperature treatment advances flowering in Clivia miniata (Lindley) Regel
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: C.B. Honiball --- Department of Plant Production and Soil Science, P.J. Robbertse --- Department of Plant Production and Soil Science,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%... -
Effect of timing and concentration of rest breaking agents on budburst in ‘Bing’ sweet cherry under conditions of inadequate winter chilling in South Africa
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A.G. Sheard --- Department of Horticultural Science, South Africa S.D. Johnson --- , South Africa N.C. Cook --- , South AfricaThe effect of timing of various rest breaking agents (RBAs) on vegetative and floral budburst, and production efficiency was investigated on 4-year-old ‘Bing’ sweet cherry trees on ‘Gisela® 5’ rootstock. Two experiments were conducted, near Clarens (28°28’S; 28°19’E, 1860 m.a.s.l)... -
Overhead irrigation increased winter chilling and floral bud production in Eucalyptus nitens
Item type: Journal Article • Journal: Southern Forests: a Journal of Forest Science • Authors: Robin AW Gardner --- Institute for Commercial Forestry Research, South Africa Isa Bertling --- Horticultural Science, School of Agricultural, Earth and Environmental Sciences, South Africa Michael J Savage --- Agro-meteorology, Soil-Plant-Atmosphere Research, School of Agricultural, Earth and Environmental Sciences, South AfricaEucalyptus nitens requires a sufficiently cold winter to produce flower buds. In areas in South Africa where E. nitens commercial plantations as well as breeding and production seed orchards are located, winter chilling is often insufficient for floral bud initiation... -
Effect of production site, storage duration, and hot water and molybdenum dips on bioactive compounds with antioxidant properties in lemon flavedo during cold storage
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: Nhlanhla Mathaba --- School of Agricultural, Earth and Environmental Sciences, South Africa John P Bower --- School of Agricultural, Earth and Environmental Sciences, South Africa Isa Bertling --- School of Agricultural, Earth and Environmental Sciences, South AfricaCertain bioactive compounds, such as vitamin E (α-tocopherol), vitamin C (ascorbic acid), β-carotene, polyphenols (e.g. flavonoids and flavonones, viz. hesperidin and naringin) have antioxidant properties and their presence in the citrus flavedo plays a significant role in mitigating oxidative stress,...
