Millerandage
The phenomenon of millerandage is specific to vines. It manifests itself as a lack of fertilisation of the berries, resulting in the absence of seeds inside them. The total or partial absence of seeds, the main site of production of plant hormones, reduces the flow of nutrients to the berries, essentially leading to three different types of millerandage: green, sweet and parthenocarpic.
- Green millerandage occurs when the berry forms without pollination, remaining small and green.
- In sweet millerandage, pollination occurs but not fertilisation; the berries still ripen to a smaller size. Despite this, they possess an excellent aromatic component with a high sugar content.
- Parthenocarpic millerandage is characterised by early seed death after pollination and fertilisation, as for example in the Sultanina grape.
The use of the organic fertiliser BioAksxter® M31 Viticulture, during the entire vegetative cycle and in particular during the phenological flowering phase, ensures optimal fertilisation of the berries by avoiding green millerandage. By providing the plant with readily available energy, it promotes soft millerandage and ripening of the grapes. This makes it particularly suitable both in the cultivation of table grapes and for all grapes destined for the production of high quality wines.
