Fruit removal force (FRF) of sour cherry, Prunus cerasus L. ‘Montmorency’, was markedly reduced by foliar sprays of 2-chloroethylphosphonic acid (CEPA) applied 3-15 days prior to harvest. The maximum reduction in FRF occurred with CEPA 6 days after treatment for all concentrations (500, 1000, 2000 and 4000 ppm). In addition to a reduction in FRF the dispersion of the individual FRF values was significantly reduced. Fifty per cent fruit removal with the 500 ppm treatment was accomplished by a… 

Effect of ethephon on sweet cherry pedicel-fruit retention force and quality is cultivar dependent

This research documents genotypic-specific pedicel-fruit abscission characteristics and the potential to facilitate mechanical harvest of fresh market quality sweet cherry fruit using ethephon.

Organ Loss and Yield Impacts of ‘Valencia’ Sweet Orange in Response to Fruit Abscission Agents

The use of the abscission agent 5-chloro- 3-methyl-4-nitro-1H-pyrazole (CMNP) in combination with mechanical harvesting increases mature sweet orange fruit removal without causing phytotoxicity to leaves and young developing fruit through most of the harvesting season.

Cherry fruit abscission: evidence for time of initiation and the involvement of ethylene.

Neither the rate of evolution nor the internal concentration of ethylene in the fruit were correlated with fruit abscission and similar abscissions responses, as indexed by FRF and sensitivity to ethylene, were observed in attached fruit and in detached fruit explants.

Physiological changes associated with senescence and abscission in mature citrus fruit induced by 5-chloro-3- methyl-4-nitro-1H-pyrazole and ethephon application

This research compares effects of the compound 5-chloro-3-methyl-4-nitro1H-pyrazole (CMNP), a plant growth regulator that selectively promotes abscission in mature citrus fruit (Citrus sinensis), and

Differential Effects of 1-Methylcyclopropene on Citrus Leaf and Mature Fruit Abscission

ADDITIONAL INDEX WORDS. 5-chloro-3-methyl-4-nitro-1H-pyrazole, Citrus sinensis, coronatine, ethephon, fruit detachment force, methyl jasmonate ABSTRACT. 1-MCP is a gaseous ethylene binding inhibitor

Effect of calcium, (2-chloroethyl) phosphonic acid and ethylene on bean leaf abscission

CaCl2 completely inhibited the abscission-enhancing effect of Ethephon in intact bean leaves, and calcium pre-treatment prior to ethylene treatment of debladed plants delayed abscissions as compared to those treated with ethylene alone.

Effect of Growth Regulators on Ascorbic Acid Content, Drained Weight and Color of Fresh and Processed ‘Rainer’ Cherries1

Gibberellic acid (GA) applied at 20 ppm 4−6 weeks before harvest increased the ascorbic acid content of fresh and processed ‘Rainier’ cherries (Prunus avium L.) while also increasing fruit size and

Chemical compositions of exudates from succulent plants induced by methyl jasmonate

AbstractMethyl jasmonate (JA-Me) promoted leaf abscission of succulent plant, Crassula lycopodioides, and exudation from stems and leaves after leaf abscission when it was sprayed in whole plants.

Ethephon Tissue Penetration and Harvest Effectiveness in Olive as a Function of Solution pH, Application Time, and BA or NAA Addition

C, osmium tetroxide Abstract. Fruit removal force (FRF) and percent leaf drop (LD) of fruit-bearing olive ( Olea europaea L.) shoots were examined 120 hours after being sprayed with ethephon at 600

Expression of Ethylene Biosynthesis and Signaling Genes during Differential Abscission Responses of Sweet Orange Leaves and Mature Fruit

A BSTRACT . When applying abscission agents to tree fruit to facilitate harvest, it is desirable to loosen fruit and not leaves or other organs, but mechanisms controlling leaf and fruit drop are not
