INFLUENCE OF CLIMATICAL CONDITIONS ON GROWTH AND FLOWER YIELD OF ANTHURIUM ANDREANUM |
| Author: | Ir. L. Leffring |
| Abstract:
An experiment on the influence of light intensity on flower production was conducted to improve yield. During three years plants were grown under the following conditions. By means of an automatical shading system outside the glasshouse the light intensity inside was at least 45% of the available light. A leaf cooling system by means of overhead sprinklers prevented leaf burning on sunny days. Under these conditions both growthrate and the formation of lateral shoots increased the average flower production from 5 till 12 flowers per plant per year. Moreover, improved selection seems possible because a variation of 0 – 49 flowers per plant per year was found in the plant material. Normally a variation exists from 0 – 7 flowers per plant per year. | |
