Wild Blueberry Fruit Drop: A Consequence of Seed Set?

A Virus Associated with Blueberry Fruit Drop Disease

During the past few years a fruit drop symptom has been observed in several blueberry fields in Oregon, Washington and B.C. The plants flower normally, though the young leaves and flowers have a transient red coloration that is absent in healthy plants. The fruit develops to 3-5 mm in diameter and then aborts so that affected bushes mature virtually no fruit. The incidence within fields increas...

Factors Affecting Fruit Set/Early Fruit Drop in Avocado

Molecular regulation of seed and fruit set.

Seed and fruit set are established during and soon after fertilization and determine seed and fruit number, their final size and, hence, yield potential. These processes are highly sensitive to biotic and abiotic stresses, which often lead to seed and fruit abortion. Here, we review the regulation of assimilate partitioning, including the potential roles of recently identified sucrose efflux tr...

Fruit size in wild olives: implications for avian seed dispersal

Frugivorous birds in the Mediterranean basin may disperse seeds using two different feeding behaviours: swallowing the fruit whole or pecking pieces of pulp. Swallowing is the common behaviour of frugivorous seed dispersers in the Mediterranean basin (Herrera 1984a) and most of the fleshy-fruited plants in the region rely on this bird feeding behaviour to disperse their seeds (Herrera 1984b, 19...

Blueberry and cranberry fruit composition during development1

Compositional changes that occur during fruit development affect both the organoleptic and nutritional quality of small fruit. Compositional changes in blueberry (Vaccinium corymbosum L) and cranberry (Vaccinium macrocarpon Aiton) fruit were determined at 3 maturities (white, turning and fully colored) during 2 seasons by analyzing sugar, acid, total phenolic, and total anthocyanin composition,...
