Abstract
The raspberry growing industry is expanding into various climates and production systems to ensure year-round availability of high-quality fruits.
Achieving this goal while maintaining high orchard productivity requires the implementation of cultivation techniques that manipulate the plant growth cycle, starting from the nursery stage.
Producing high-quality fruit requires a thorough understanding of the raspberry growth cycle and the factors that influence it, including flower induction and plant architecture.
Additionally, off-season production relies on precise scheduling of flower differentiation during specific periods of the year (Carew et al., 2000). Understanding plant branching and flower positioning is essential for optimizing pruning and cultivation methods tailored to the unique characteristics of each cultivar.
In fact, different raspberry cultivars exhibit distinct flowering timelines, growth habits, and fruiting behaviors.
Cultivation techniques – such as nursery management, cold storage, transplanting dates, and pruning systems – must be adjusted according to the specific requirements of each cultivar to control fruit production timing effectively.
Raspberry cultivars are generally classified into two categories based on their fruiting habits: floricane (biennial) and primocane (annual) (Carew et al., 2000). This distinction is crucial from an agronomic perspective, as each type requires specific cultivation strategies.
The main objective of this study is to explore the manipulation of the raspberry growth cycle, not only based on the floricane and primocane genotypes but also through the interaction of plant physiology, genotype, artificial chilling requirements, transplanting date, pruning systems, and nursery plant type.
By strategically managing these factors, it is possible to achieve year-round raspberry production.
