Vroege detectie kiepers in tulp met hyperspectrale camera: Verkenning van mogelijkheden om met behulp van een hyperspectrale camera kiepers in tulpen vroegtijdig te detecteren

Keeping humidity below <80% in the forcing of tulips prevents flowers from losing solidity and tipping over in a later stage. However, much energy is needed for dehumidification. Previous research has shown that there are differences in timing that tulips are susceptible to tipping between varieties, batches, temperature treatment, greenhouse conditions and fertilization. As soon as the first symptoms of tippers can be observed with the naked eye, tipping at a later stage is unavoidable. Faster detection of tippers within the cultivation process might offer a solution. That is why WUR has explored the possibilities of spectral cameras, which are expected to be able to detect tippers earlier. Measurements at ‘Purple Prince’ and ‘Strong Gold’ showed that cameras can already see after 4-5 days that tulips have been grown at high RH, while a trained observer sees the first symptoms only after 8 days.
