The varieties suitable for cold climate (high-chilling requirements) need at least 500 hours of cold to properly grow and produce fruits.
They are suitable for cultivation in temperate and continental climates with sufficiently long winters to meet their cold needs.
The varieties suitable for warm climate (low-chilling requirements) need less than 500 hours of cold to properly grow and produce fruits.
They are particularly suitable for production in sub-tropical Mediterranean areas.
Dedicated to INDUSTRY:
This kind of varieties can produce fruits throughout the entire growing season in any climate, beginning in spring, with intermittent crops throughout summer and early fall.
They are also called day-neutral varieties and can be divided in two categories: low-chilling or high-chilling.
