01 Oct 2024

Attraverso un'analisi cinetica della reazione di metanolisi, i ricercatori sono riusciti a modellare il processo utilizzando due modelli: uno basato su una reazione pseudo-primo ordine e l'altro sul comportamento auto-catalitico del meccanismo di reazione (CRM-AB).

A new biodegradable film for sweet cherry packaging

Post-harvest​

26 Sep 2024

A group of Chinese researchers has developed a biodegradable composite film made from gelatin, pectin, and cellulose nanofibers (CNF), enriched with an antibacterial agent called polyhexamethylene biguanide hydrochloride (PHMB).

Trunk diameter variations as indicators of water stress in sweet cherry trees

Tech management

23 Sep 2024

A Spanish study used sensors to monitor trunk diameter variations (dendrometers) in “Lapins” cherry trees, comparing various indices derived from these data with the traditional stem water potential, considered one of the most reliable indicators of plant water stress.

The importance of wood age, rootstock, and cultivar in sweet cherry cultivation

Tech management

20 Sep 2024

A recent study conducted Ukraine focused on the influence that wood age has on key sweet cherry productivity parameters. The results showed that wood age is one of the main factors determining productivity: three-year-old wood sections showed the highest flower density.

Sweet cherry packaging: the use of perforated bags to maintain quality

Post-harvest​

19 Sep 2024

A study by Chinese and American researchers analyzed the effectiveness of different perforation levels in zipper-lock bags to extend the freshness of “Chelan” and “Lapins” sweet cherry cultivars. The goal was to reduce the weight loss and improve resistance during post-harvest.

The influence of trunk height on sweet cherry quality

Quality

18 Sep 2024

Interestingly, cherries from trees with a trunk height of 60-65 cm retained their quality for a longer period compared to those from other heights, showing less weight loss and maintaining a higher level of firmness and soluble solids.

Bio-insecticides Based on Terpenes and Phenylpropanoids as Alternatives for the Control of Drosophila suzukii

13 Sep 2024

A recent study conducted by Brazilian researchers investigated the effectiveness of specific terpenes and phenylpropanoids in controlling D. suzukii and evaluated their effects on non-target organisms, showing interesting results on their potential as bio-pesticides.

Sweet cherry tree prioritizes water stress response over pathogen defense

Crop protection

11 Sep 2024

A study conducted by Chilean and Spanish researchers analyzed the balance that sweet cherry trees must manage between responding to drought conditions and defending against pathogens like Pseudomonas syringae pv. syringae (Pss). The study focuses on cv. Bing and cv. Santina.

Understanding sweet cherry water needs through sap flow measurements

Tech management

05 Sep 2024

A study conducted near the city of Ficksburg, South Africa, from September 2017 to December 2018 highlighted the sweet cherry tree's sensitivity to soil moisture levels, especially during critical growth stages, where water stress can significantly impact the yield.
