Carnival Greenfield, Elizabeth Joy Jacobs, G. Theron, K. I. Stellenbosch University. Faculty of AgriSciences. Dept. of Horticultural Science. Protea -- Pruning Protea -- Growth Crops and nitrogen Carbohydrates Dissertations -- Horticulture Thesis (MScAgric) -- University of Stellenbosch, 1994. Protea cv. Carnival is a natural hybrid of probably P. compacta and P. nerifolia. ‘Carnival’ is a perennial, evergreen shrub indigenous to South Africa. It is grown commercially and the cut flowers are exported to Europe. Current pruning practices where plants are pruned during their flowering time from February to May result in a low yield of saleable flowers. ‘Carnival’ plants were therefore pruned at different times (from 12 March 1991 to 17 September 1991) to determine the effect on the yield of saleable flowers. Plants pruned on 2 July 1991 and later did not flower the following season. Plants pruned from 12 March 1991 to 21 May 1991 produced inflorescences in decreasing amounts. Apparently, at least two consecutive flushes are needed for inflorescences to form, with no inflorescences forming on the autumn or second summer flushes. Varying the number of bearers per trunk circumference on both two- and six-year-old plants produced no significant differences in yield. The seasonal changes of total nitrogen, starch and reducing sugars in wood and bark of two-year-old shoots were recorded in pruned and unpruned plants for 23 months. Reserve carbohydrate and nitrogen remained low throughout the year, showing that two-year-old wood and bark are not an important source of reserve nitrogen and carbohydrate. The starch and reducing sugars in wood were lower than the corresponding levels in bark.
