Comparative study between natural, entomophilic and manual pollination in soursop (Annona muricata L.)

Abstract

This research was carried out in the communities of Tonino and Divisadero municipality of Compostela, Nayarit, Mexico with the objective of studying the effect of natural, entomophilic and manual pollination of soursop fruits. Pollinations were carried out during the June-July period of 2017 (summer flowering). Which treatments consisted of the natural pollination that only perforated bagging was placed, The variables were: peduncle diameter, brush or strawberry diameter, percentage of yield, percentage of fruit fall, dynamics or general kinetics of growth variables and general behavior of loss and fruit fall. Percentage yield as it was low from 6 to 21% and this decreased as the evaluation time elapsed due to the fall in fruit. The fall of the fruit of the three treatments was considered to have a very important factor whereby they fell, the lack of coverage with fungicides or insecticides.
