Freesia crop (Freesia x hybrida) phenological growth stages according to the BBCH scale = Estadios fenológicos del cultivo de fresia (Freesia x hybrida) según la escala BBCH
Freesia x hybrida has an important role in the global cut flower market. This work describes the phenological events of the crop as can be coded according to the BBCH scale (Biologische Bundesanstalt, Bundessortenamt, Chemische Industrie). Laboratory and field trials were carried out, and four planting dates were considered to check whether all the phenological development phases took place under different environmental conditions. From planting date to crop senescence, the plants were observed daily so as to pinpoint their phenological phases. Photographs were taken every day to record morphological changes in both aerial and underground parts. Six main development phases were recorded, described, and coded: sprouting (stage 0), leaf development (stage 1), development of the vegetative propagated organ (stage 4), inflorescence emergence (stage 5), flowering (stage 6), and senescence and beginning of dormancy (stage 9). Secondary stages were also discriminated within each main stage, and a mesostage was proposed to describe crop growth more accurately. During the crop cycle, there were some development phases that took place simultaneously. The description and coding of freesia plant development contributes a new and precise tool to the study of the different growth phases of the crop, the knowledge of which is essential for commercial production, and for introducing crop management practices that secure cut flower quality.
