Depending on the climatic conditions and the cultivation area, the flowering season of the olive tree can be advanced or delayed. The olive tree flower receives different names according to the geographical area. In Spain, the flowers of the olive tree are known by the following names : rapa , plot , sample and esquimo. The varieties of self-fertile olives are better able to set and are self-sufficient. However, when the conditions are not favorable, the crossing of pollen between different varieties of olive trees favors a greater setting compared to that of monovarietal crops.

During olive tree flowering time , olive trees release a huge amount of pollen into the atmosphere. The wind is responsible for transporting pollen and is essential in the pollination of the olive tree. When olive pollen concentrations in the air are high, the appearance of allergies to the olive tree usually Be quite common.

Excessively high temperatures during olive tree blossom reduce the fertility of olive tree pollen. This negatively influences the fruit set. If during olive tree blossom there are intense and constant rains for several days, they wash the pollen and can reduce the harvest.

On the contrary, fresh and moist air favors that the pollen can move. By maintaining its ability to fertilize for a longer time, it drives a greater load of olive trees. The presence of water reserves in the soil also favors a better olive curd. During the flowering of the olive tree, the antophageal generation of the prays or olive moth can damage some flowers.

Damages are negligible when olive tree blossom is abundant. The correct sanitary state of the olive trees favors the fruit set with an abundant flowering. On the other hand, there are the self-sterile olive tree varieties , among them are Gordal Sevillana , Morisca , Morchiaio or Frangivento.

Normally, these are olive varieties with a high ovarian abortion. Other varieties are partially self-compatible by releasing olive pollen with poor fertility. Empeltre , Biancolilla , Villalonga or Picholine are demanding olive varieties with pollination. We have translated the information on our website from Spanish to English. Note that some words may have seen their meaning altered during their translation.

Olive Growing Cycle

Spinardi, D. Self-compatibility of local olive Olea europaea L. Following self-pollination, fruit set was significantly lower and the occurrence of shot berries significantly higher than those obtained by open pollination. No significant effect of controlled cross-pollination over self-pollination on fruit set and shotberry set was detectable. Foliar B application enhanced in vitro pollen germination, and the optimal level was higher for pollen germination than for fruit set.

Although most olive varieties are self-fertile to some extent, research has shown that cross-pollination generally improves the fruit set of most varieties especially when the environment conditions are not optimal. Generally having two or three different varieties growing in close proximity 30m will facilitate adequate cross-pollination. Arbequina, Pendulino, Coratina, Picual and Manzanillo are some of the main varieties used for cross-pollination. If a tree flowers well in the spring and does not set any fruit it may be an indication that cross-pollination is required.
