The flowering of fruit trees is a gradual process within the evolutionary cycle of the plant that, however, covers a relatively short period of time. In this phenological stage of the crop, it is essential to apply biostimulant treatments that act on the quality of the flowering process and subsequent fruit setting, and that help maintain an optimal level of fruits per tree.

After the winter rest, stone fruit trees have started a new biological cycle. The sap is reactivated, the plant leaves its dormant state and new sprouts begin to occur that will give way to the first blooms.

Several factors intervene in this process. The weather plays a relevant role in the flowering of fruit trees. We assume that trees need to accumulate hours of cold in order to regulate their vegetative cycle. Otherwise, sparse or too staggered blooms may occur.

Frost episodes can cause the loss of a large part of the flowering or even the newly set fruits, while high temperatures can influence the reduction of the pollination period or cause floral abortions.

In addition to the accumulation of winter cold, the load and flowering levels of the previous year also intervene in the flowering of fruit trees.
