Remontancy of Citrus

In citrus, remontancy does not imply obtaining several independent harvests, as the long fruit development cycle of approximately 9 months results in subsequent waves of flowering merely extending the fruiting period. The trait is evaluated through phenological observations of the number of flowering waves, recording the simultaneous presence of flowers and fruits of different ages on the plant, and by classifying cultivars based on their propensity for continuous ovary formation.

Highly remontant cultivars, such as 'Yubileiny', 'Meyer', and 'Genoa' lemons, are capable of forming shoots and fruits uniformly throughout the year, whereas low remontancy manifests as two distinct flowering phases. This trait complicates agrotechnical management, as the redistribution of nutrients during the emergence of new buds can trigger ovary drop, and the year-round presence of vegetative organs on the plant facilitates the continuous development of pests in protected cultivation.
