Application of plant phospholipids improves cellular resistance against cracking

Tech management

16 Dec 2024

Biotens is a product that integrates into the plasma membranes of plant cells because it has the same composition (vegetable phospholipids). Biotens, due to this characteristic, does not cover the stomata and does not interfere with the dynamism of the plant's plasma membran.

Picota del Jerte in trouble, appropriate insurance policies required against climate damage

The president of the Protected Designation of Origin Cherry of Jerte, José Antonio Tierno, lamented the loss of 40% of the season for cherries, which are harvested earlier, and 70% of picota, which matures later. This translates into economic losses exceeding 15 million euros.

Late frost and cracking: how to reduce damage with melatonin

Tech management

03 Dec 2024

The aim of the study conducted by the post-harvest group of the University Miguel Hernández (Orihuela, Spain) and the Valencian Cooperative Mas de Roc was to find out whether melatonin can be used as a control measure against late frost and cracking.

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.

Combating cracking by controlling the osmotic pressure of cherries

22 Aug 2024

The aim of the research conducted by Portuguese and Spanish universities was to improve the quality and profitability of sweet cherry trees cv. Sweetheart by administering foliar biostimulants based on calcium and seaweed (Ascophyllum nodosum).

Pre-harvest strategies to reduce the risk of cracking

Quality

19 Aug 2024

In research funded by the Government of Aragon, a relationship was identified between the rate of cracking and the amount of flavonoids present in the epidermis of the underside of the fruit. As the amount of flavonoids increases, the frequency of cracking also increases.

How Calcium and Potassium increase resistance to cracking and accelerate ripening

07 Aug 2024

The experiment was carried out in a commercial orchard of sweet cherry cv. 'Regina' in Lagnasco, Piedmont, grafted on 'Gisela 5', covered by rain and hail nets. Foliar applications were carried out on 15 plants with: Stimulant Plus®, Set® and Abundantia®.

Calcium absorption: useful information for sweet cherry orchard management

19 Jul 2024

The study used the stable isotope of calcium (44Ca) to distinguish between different sources and to understand its absorption and distribution during the various phenological stages of fruit development, in this case on the cultivar ‘Lapins’ grafted on ‘Colt’.

German study reveals how calcium chloride can solve the fight against cracking
