Flower formation in the olive tree

The fruiting cycle in the olive tree, i.e. flower differentiation and development, fruit set and ripening, lasts for one year (Sfakiotakis, 1993). Flower formation in the olive tree takes place in the period from late January to early June. The critical period for flowering is January and February. During this period the physiological changes that make the meristem floral take place.

Eye development

A very important application that can provide a sufficient supply of essential nutrients and motivate the olive tree to form more full flowers later is the spraying with Maxi-Grow 0.5 kgr, Fosfacel 2 kgr and Barrier 2 kgr/tonne.

Flower formation - Blossoming of flowers

At this stage it is very important to have sufficient boron and zinc to produce high quality pollen with good germination (even in periods of high temperature and humidity) so spraying with Tropicel 1 kgr and Barrier 2 kgr/ton is important.

Crocus - Beginning of flowering

Full flowering occurs in the southern regions of the country in April and in the colder regions in May depending on the local climatic conditions and the variety of the olive tree.
Subsequently, spraying with Maxi-Grow 0,5 kgr and Barrier 2 kgr/tonne is recommended, which significantly increases fruit set, reduces competition between flowers and ultimately leads to the production of the maximum number of fruits per blossom.

End of flowering

Knowledge of the period of differentiation and flower formation in olive trees is critical and coincides with the start of new vegetation formation (Sfakiotakis, 1993). In olive groves that are not irrigated and not sufficiently supplied with nutrients there is a tendency for miscegenation. In order to strengthen cell division and to regulate the necessary germination that will give the next year’s production, spraying at the end of flowering with Tricel 2 kgr and Maxi-Grow 0,5 kgr/tonne is recommended.
