The presence of double fruits and deep sutures in cherries is a serious problem for Chilean cherry cultivation, negatively affecting the quality and condition of the fruit.
This physiopathy could become an even greater production problem in the coming years, considering that the factors that predispose to it (mainly high temperatures and water deficit situations during the cherry's flower differentiation period), are becoming more and more frequent in Chile and other cherry growing areas in the world.
The use of protective nets and the application of sunscreen seem to be the most valid tools for producers to mitigate this problem in their orchards.
In this regard, the work of Chilean researchers at the University of Concepcion is aimed at studying the environmental and physiological variables that regulate the induction of double fruit and deep sutures in cherries in order to propose new solutions to control this physiopathy, which are more effective and less costly than the means currently available.

The objectives of the study was to phenotype a segregating population of sweet cherries for selected key traits of the Zipper model and for their susceptibility to cracking, for which the QTLs for cracking susceptibility were established earlier.

A recent study in Ukraine's steppe region analyzed 35 sour cherry combinations to identify the most drought-tolerant, evaluating key physiological traits like water retention, leaf hydration, turgor recovery and plant response to extended water deficit stress.

A three-year study in Poland compares organic and conventional sour cherries, showing that cultivar, climate and season affect fruit quality more than orchard management alone. Oblačinska stands out as the most promising cultivar for high-quality organic production.
