Crop protection

07 Feb 2025

A recent study from Korea investigated the combined effect of ethyl formate (EF) and cold on this invasive species, analysing metabolic changes to better understand the impact on the insect's physiology.

The use of modified atmosphere for sweet cherry preservation

Post-harvest​

06 Feb 2025

A recent study from Romania evaluated the effectiveness of using Xtend modified atmosphere packaging in maintaining the quality of "Kordia" and "Regina" cherry varieties. The cherries were stored at -0.5°C for 42 days.

From sweet cherry pruning waste to a resource for sustainable biocomposites

Tech management

30 Jan 2025

A study involved collecting branches from trees located in mountainous regions of Turkey, at approximately 1,600 meters above sea level. After careful drying and grinding, the branches were processed into wood and bark particles with sizes smaller than 100 micrometers.

Dry matter as an indicator of sweet cherry maturity and quality

Post-harvest​

29 Jan 2025

A study utilized the CTIFL color scale to classify cherries into three maturity levels analyzing the fruit both before and after a 28-day storage period. Cherries with optimal dry matter levels exhibit lower respiration rates, which helps maintain flavor during storage.

Cracking susceptibility of full-sibs of a cross of a cracking tolerant and cracking susceptible sweet cherry: relation to cuticle characteristics, microcracking and Calcium

Breeding

20 Jan 2025

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.

Propagation of GiSelA 5 rootstock: which method to choose to optimize its performance in cherry orchards

Nurseries

14 Jan 2025

A recent study from Poland compared two propagation methods for GiSelA 5: the use of stem cuttings and the in vitro method, evaluating their impact on tree growth, particularly on the varieties “Bellise”, “Earlise”, “Lapins”, and “Vanda”.

Cherry replanting management: strategies for nematode control

Tech management

13 Jan 2025

A two-year study conducted in the United States on two sweet cherry cultivars, “Emperor Francis” and “Ulster,” analyzed six different soil treatment strategies to identify the best solutions for improving tree growth and managing nematodes.

The role of PavSPL genes in sweet cherry development

Breeding

09 Jan 2025

A recent Chinese study analyzed their role in sweet cherry (Prunus avium). The findings showed that the seasonal expression of PavSPL genes varies throughout the plant's annual cycle, particularly during the post-dormancy recovery period.
