The Çakır olive: a cultivar that asks for a thousand hours of cold
Reported alongside Ayvalık and Domat with a 1000-hour chilling requirement — the group most at risk as winters warm.
Çakır is one of the Aegean's local olive varieties, and measurements place it in the high chilling requirement group: 1,000 hours, the same figure reported for Domat and Ayvalık.

What a thousand hours means
A thousand hours is roughly 40 to 45 days of uninterrupted suitable cold. Failing to meet it doesn't kill the tree, but it disrupts flowering that year — and the crop drops.
At the other end of the scale sits Adana Topağı at 346 hours. In other words Çakır needs more than three times what the least cold-demanding variety asks for.
That narrows the geography it can grow in: only regions whose winters are long and cool enough. And in warming winters it belongs to the group that runs into trouble first.
⚠ The same measurement study records years in which Ayvalık and Domat did not have this requirement met. Since Çakır sits in the same group, it carries the same risk.

Missing data
For Çakır we only have the chilling figure. No verified published source was found for fruit weight, oil content, flesh-to-stone ratio or self-fertility.
This is the common situation for local varieties in Turkey: their names appear in variety inventories, but pomological measurements have either not been made or not been published. This page will be updated when measurements are found.
In short
The only measured property known for Çakır is its high chilling requirement: 1,000 hours. That places it alongside Ayvalık and Domat — the varieties most at risk of flowering trouble in warming winters.
Note on sources
The pomological and chilling values on this page come from a comparative trial of Turkish and foreign olive varieties conducted under Adana conditions. Properties without a measurement have not been filled in by estimation; they are left blank.

Values are those published on each variety's own page; the comparison covers only varieties with a measured figure, so it is a comparison of what is known — not of every Turkish variety. See the full ranking and how it is built →
