FLOWERING AND VEGETATIVE GROWTH OF PROTEA NERIIFOLIA AND PROTEA CYNAROIDES |

| Abstract:
Differences in the flowering period and in the productivity of Protea cynaroides ‘Long Leaf’ occur between four commercial plantations in Southeastern Australia. The number of flowers varies from 45 flowers on 17 plants (2.65/plant) to 16 flowers on 5 plants (3.2/plant). The clone Protea neriifolia ‘Salmon Pink’ has a different bloom distribution and yield at each plantation. More blooms were produced at the two warmer plantations. Bloom production at each plantation on 25 plants varied from 26 to 112 during 1988 to 157 to 579 during 1989. The two species have different vegetative phases resulting in different seasons of flowering. Soil particle analysis and nutrient levels influence root growth and shoot development. | |
