A PRODUCTIVITY AND PARTITIONING APPROACH TO CARNATION PRODUCTION |

| Abstract:
A whole-crop approach to modelling the production of cut flowers was used to examine components of productivity for low-disbud selections of standard carnations (Dianthus caryophyllus L.). In order that availability of sinks would not limit dry matter gain, the plants were spaced to 220 sinks (active meristems) per square meter. The total dry weight gain of the low-disbud cultivars varied between 10 and 18% less than the 2263 grams theoretically derived. The photosynthetic efficiencies of the crops were between 4.6 and 5.8%. Methods for manipulating dry weight partitioning to maximize production of flowers are discussed. | |
