Effect of cyanamide and girdling on yield, fruit size and quality of De Wet peach
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: M. North --- , Republic of South Africa J.D. Stadler --- , Republic of South Africa Hannelie de Villiers --- , Republic of South AfricaTrees of an early-ripening peach cultivar, De Wet, were given a dormancy-breaking spray of hydrogen cyanamide and later girdled, in an attempt to improve fruit size and earliness. Girdling promoted a significant increase in fruit size, total soluble solids (TSS)... -
Effect of cyanamide and DNOC/oil on budbreak, yield and fruit size of Golden Delicious apples
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: M. North --- , Republic of South AfricaCalcium cyanamide (CaCN2), hydrogen cyanamide (H2CN2) and DNOC/oil (dinitro-o-cresol/oil emulsion) were evaluated as rest-breaking agents on Golden Delicious apples during two seasons and in two climatic zones. In the moderate climatic zone, a double and single application of DNOC/oil gave... -
Alternative rest-breaking agents to DNOC/oil for apples
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: M.S. North --- , Republic of South AfricaRest-breaking agents less toxic than the commercially-used DNOC/winter-oil and less expensive than hydrogen cyana- mide were tested on Golden Delicious in a high density planting in a region of warm winters. Some combinations of mineral oil and cyanamide were as... -
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)...
