    Abstract In several ornamentals there is insufficient certainty about the flowering results. Wageningen UR Greenhouse Horticulture and NSure have investigated whether flowering results can be improved with the development of molecular tests. In crops such as snowball (Viburnum opulus 'Roseum’), Hydrangea, azalea and Syringa flower buds go into winter dormancy in autumn. Flowering results of these crops can be improved when it is possible to measure when winter dormancy is sufficiently broken to force these crops successfully. For Viburnum a molecular test has been developed and successfully tested. For Hippeastrum, Bromelia, Cymbidium, Miltonia, Nerine and Zantedeschia it was investigated whether development of a molecular test can improve flowering results. For Cymbidium a greenhouse experiment was conducted with 0, 2, 4, 8, 13 and 16 weeks 13 oC from week 44 - 2010 and plant samples were collected at the end of the treatments. As plants stood longer at 13 oC, the number of inflorescences autumn 2011 increased. The collected samples can be used to develop a molecular test in the future.
