Factors Affecting Fruit Set/Early Fruit Drop in Avocado

The Physiology of Apple Pre-harvest Fruit Drop

As apples ripen they begin to produce large amounts of the ripening hormone, ethylene. Ethylene stimulates fruit softening and the formation of an abscission zone in the stem. Ethylene stimulates the production of enzymes (cellulase and polyglacturonase) that break down the cell walls and the glue that holds cell walls together in the abscission zone of the stem, leaving the fruit connected to ...

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...

Role of Growth Regulators on Preharvest Fruit Drop, Yield and Quality in Kinnow Mandarin

The study was undertaken to envisage the effect of growth regulators on preharvest fruit drop and quality of Kinnow mandrin (Citrus reticulata Blanco). Various concentration of 2, 4-D, GA3 and NAA were applied during the last week of November, 2005 to check the impact of various treatments on preharvest fruit drop, yield and fruit quality. Exogenous application of growth regulators significantl...

Cultivar and fruit size influence bruise susceptibility and some physical properties of apple fruit

ABSTRACT- For most fruit types, including apples, bruising is the most common type of postharvest mechanical injury. Bruise susceptibility was investigated in 3 commercial cultivars (‘JazzTM’, ‘Granny Smith’ and ‘Fuji’) and among a range of 4 different fruit sizes (commercial counts of 135, 120, 100, and 88) in each cultivar. Bruising was carried out by dropping a uniform round steel ball (110g...
