The importance of rootstock and fertilization in Summit cherries quality

Tech management

21 Nov 2024

A Chinese study analyzed the effects of five different rootstocks on Summit sweet cherry cultivar during the fruit veraison phase with or without nitrogen-free nutrient fertilizers. The five rootstocks tested were: Mahaleb, Gisela 5, and three hybrid selections H11, H17, and H22.

Diversity of Colletotrichum species responsible of cherries post-harvest anthracnose in China

Post-harvest​

19 Nov 2024

A recent Chinese study analyzed various cherry samples collected over two different growing seasons. From these samples, 43 isolates of Colletotrichum were obtained and characterized, representing the species associated with anthracnose in the main cultivation regions.

Cross-species SIT technique: a new frontier for controlling Drosophila suzukii

Crop protection

13 Nov 2024

A recent Italian study analyzed the use of cross-species SIT, which leverages reproductive interference between different species to enhance effectiveness. The goal was to combat Drosophila suzukii, a pest that poses a threat to fleshy fruits such as cherries.

Analysis of fungal diversity responsible for cherry fruit rot in Shandong province, China

Crop protection

11 Nov 2024

Pathogenicity tests showed that all isolated species could cause fruit infections, though with varying levels of aggressiveness. Among them, Diaporthe eres displayed the highest virulence followed by Fusarium incarnatum and Botryosphaeria dothidea.

Biotechnological innovations in the control of Drosophila suzukii: techniques and perspectives

Crop protection

05 Nov 2024

Traditional management methods fail to fully control Drosophila suzukii. New innovative strategies are being developed and adopted, including the 'sterile insect technique', 'X-shredding' and the 'transgenic sexing strains' technique.

Prediction and control of Drosophila suzukii: the SIMKEF model

Crop protection

29 Oct 2024

The SIMKEF model, which aims to predict and control the insect using models based on temperature data, combines various climatic and biological parameters to estimate the (daily) probability of occurrence of the pest.

Expansion of sweet cherry cultivation in China: identifying suitable areas with a model

Planting systems

28 Oct 2024

A recent study, based on the use of the MaxEnt model, has enabled Chinese researchers to predict potentially suitable areas for the cultivation of this species in China, identifying key environmental factors that influence its distribution. The MaxEnt model proved effective.

Monitoring wetness on sweet cherry surfaces: new techniques to reduce cracking

Tech management

22 Oct 2024

Cracking is not necessarily linked to water absorption but rather to the duration of wetness presence on the fruit surface. Temperature models obtained through LiDAR 4D revealed that sweet cherry tree canopy density has a marginal impact on wetness formation.

Impact of GA3 application on sweet cherry fruit development

Quality

21 Oct 2024

An English study tested the application of gibberellic acid on sweet cherry trees for fruit development. GA3 is known for its ability to induce parthenocarpy, the formation of seedless fruits, in various plant species. However, effectiveness varies depending on the species.

The role of supercooling in sweet cherry flower buds to avoid frost damage

Tech management

17 Oct 2024

Experiments were conducted on sweet cherry flower buds using differential thermal analysis (DTA), a technique that monitors the release of heat due to ice melting. Researchers observed the formation of ice within the bud structure, identifying barriers that prevent its spread.
