The metaxenia effect, where pollen affects the characteristics of the fruit, is primarily observed in certain fruit crops. Notable examples include:

The Metaxenia effect is found in several fruit crops, such as pecan nuts, pistachio nuts and avocado (Robbertse et al., 1996; Sedgley and Griffin, 1989), but especially date palms (Nixon, 1928; Shaheen et al., 1989).

The Metaxenia effect is found in fruit crops where pollen from one variety influences the characteristics of the developing fruit (such as size, shape, color, or ripening time) before fertilization is complete.

The metaxenia effect refers to the influence of the pollen on the characteristics of the fruit's maternal tissue, leading to changes in traits like fruit size, firmness, and sweetness. Several fruit crops exhibit the metaxenia effect, which include apples, date palms, kiwifruit, blueberries and pomegranates.
