Resumen:
In many areas of Japanese plum cultivation, productivity is limited by low
flower fertility and a relevant factor in this is gametophytic incompatibility. For this
reason, cross pollination has a strongly positive effect on fruit production. In this
work the authors present results preliminary on the interaction between flower
phenology and its effect on attractiveness to pollinator insects. A population of 1,500
trees of Japanese plums (Prunus salicina Lindl.) obtained by cross-pollination within
a breeding program carried on at Florence (Firenze) and grown in San Casciano
(Tuscany, Italy), has been studied during flowering time and fruit set time during
the years 20042007. Some genotypes presented different anomalies during
microsporogenesis, with inconsistent amounts of low viability pollen. Hence, crosspollination
and fruit set depended strongly on the insect activity. Different
Hymenoptera and Diptera were observed during the anthesis and post anthesis
stages. Attraction appeared to be correlated with the pollen amount, anther color,
flavor and nectar production. Furthermore, the attractiveness to insects was
conditioned by the genetic origin of the seedling.Prunus salicina Lindl.) obtained by cross-pollination within
