Preliminary Results of Supplementary Pollination on Hazelnut in South Chile

Viability and germinability in long term storage of Corylus avellana pollen

“…For this reason, hazel requires genetically compatible pollinizer cultivar, but pollination remains an uncertain process dependent on numerous factors, such as rainfall, humidity, wind, which can affect this phenomenon in different ways (Ellena et al, 2014;Novara et al, 2016) both during the catkins elongation and pollen dispersion. Moreover, male and female flowering of compatible cultivars should overlap in order to ensure a correct pollination, but flowering can vary from year to year and the response of male anď et al, 2012; Ellena et al, 2014).…”

“…Moreover, male and female flowering of compatible cultivars should overlap in order to ensure a correct pollination, but flowering can vary from year to year and the response of male anď et al, 2012; Ellena et al, 2014). For all these reasons, artificial or supplementary pollination can be used to improve the yield.…”

Artificial Pollination in Kiwifruit and Olive Trees

“…This observation leads to define kiwifruit pollination as a new model for crop fruit pollination that could be applied in other wind pollination (anemophily) trees such as olive tree, hazelnut, and pistachio that were studied but without a practical application (Figure 4) [6,12,13].…”

“…Insufficient pollination has been found to be one of the important causative factors of low yield and low quality in many fruit tree species [3]. Supplementary pollination is a valid support to increase productivity in crop species such as strawberry [4,5], olive [6], kiwifruit [7,8], almond [9,10], pistachio [11,12], hazelnut [13], macadamia [14,15] and date palm [16,17]. Artificial pollination leads also to increase final set, weight, kernel recovery, and, in many cases, fruit quality in terms of nutritional characteristics and shelf life [4].…”

Dynamics of flowering of male and female inflorescence and pollen germination of hazel in the conditions of the Banja Luka region

“…This includes the application of artificial pollination in several stages, including: growing of trees aimed at the production of high quality pollen, collection and storage of pollen, testing of pollen viability, application of pollen by means of air pumps and ventilators at a favourable time. Positive results and elimination of problems that arise due to poor pollination have been obtained in Chile, where there was a yield increase by 37% (Ellena et al, 2014).…”
