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’.

Efficiency of phytopathological programmes with the use of dormancy breakers

Tech management

19 Jul 2024

The application of dormancy breakers is more important with a low winter cold accumulation, as it produces a loss of reserves and lower quality of flower buds, which results in lower pollen and egg viability, reducing fruit set.
