Cultivation
Rosa L.
A complex of morphological and physiological characteristics of a cultivar that determine flower stem quality, vase life, and transportability. It includes requirements for stem length, bud opening stage, and remontancy to maintain a balance between yield and commercial appearance.
In the reference 1 253 varieties crop Rose, where this is mentioned in the description.
Cut rose cultivars require long and strong stems capable of supporting the flower head without drooping, with a minimum length of 30 cm required to ensure vase life. An important morphological criterion is the shape of the bud, which should open slowly while maintaining aesthetic appeal without exposing the center prematurely, as well as the presence of healthy and dense foliage.
Physiological indicators of post-harvest quality include the flower's ability to maintain petal turgor and resistance to logistics conditions. Cultivars are evaluated on a special bud opening scale from 1 to 5, which determines the optimal cutting stage depending on the distribution channel. Production efficiency is ensured by remontancy and the ability to manage forcing schedules.
A key aspect is high resistance to diseases such as black spot and powdery mildew, as any damage renders the product unmarketable. At the same time, the harvesting technique also serves as a pruning practice that influences the formation of the subsequent crop, requiring strict adherence to cutting rules regarding the number of buds.
