Resumen

The research aimed to evaluate the effect of pollen carriers on cherimoya (Annona cherimola Mill.) production through the use of assisted pollination under conditions of the high Andean zone of the Lima region, Peru. The design used was a randomized complete block design with six treatments and three replications. The treatments were: T1) pollen carrier with chuño flour (potato starch); T2) pollen carrier with Lycopodium clavatum flour; T3) pollen carrier with white corn flour; T4) pollen carrier with wheat flour; T5) pollen carrier with industrial talc; and T6) natural pollination (control). Each experimental unit consisted of three trees arranged in a 48 m2 area. The variables evaluated were the number of fruits set per tree, yield by fruit category (t ha-1), and total yield (t ha-1). The averages were compared using the Scott-Knott test at 5% level. It was found that treatment with L. clavatum flour significantly outperformed all other treatments, obtaining more fruits set per tree, higher total yield, and higher yield in each of the categories considered; it was followed in importance by chuño flour. The control treatment produced the lowest values for the set of characteristics evaluated and was statistically lower (p < 0.05) than the other treatments. It is concluded that assisted pollination with pollen carriers significantly increases cherimoya production, with treatments with L. clavatum flour and chuño flour standing out.
