| Sumario: | Flower mapping is a morphological mapping method that can be used in strawberry (Fragaria
x ananassa) plant production to get an insight of the status, numbers and the developmental
stages of flower buds. It is commonly used by nurseries in order to evaluate plant management
techniques to achieve enhanced yield potential over time. In the present study, flower mapping
was tested with an everbearing strawberry cultivar Favori in a greenhouse production system.
In the trial flower mapping was conducted before planting and after the first harvest on two
different batches, planted at two separate dates. This was done to evaluate the applicability of
flower mapping on an everbearing cultivar and to gain experience to benefit future production
of everbearing strawberries in Sweden.
The study showed that the everbearing strawberry cultivar Favori responds to its
cultivation system and surrounding environment. The response was expressed as differences in
the development pattern and in the plant architecture. To help the interpretation of flower
mapping a frequency model was developed summarizing the bud stages and the bud
distribution. The flower mapping performed before planting gave an indication of plant quality
e.g. number of initiated buds and crown size, and helped to predict future flowering and yield
pattern. The second flower mapping conducted after first harvest peak did not predict future
flowering pattern, but gave support for the potential future development by identify initiated
buds and secondary crowns. In conclusion, flower mapping is suggested to be used as a method
to predict potential future inflorescences and to optimize the production of an everbearing
strawberry grown in greenhouse. |
