Studies on the residual behaviour of Ethephon on black and red currants showed that the fruits contained on an average 0.39, 0.81, 2.2 and 0.64, 1.14, 1.04 p.p.m. of Ethephon, respectively, after application of 0.04, 0.06 and 0.08%. Flordimex mixture. When a concentration of 0.08% was applied to gooseberries, the fruits contained on an average 0.31 p.p.

Environmental factors affecting ethephon in olive
Scientia Horticulturae, 1978Abstract Inconsistent results of ethephon in field experiments in olive ( Olea europaea L.) are attributed to climatic differences and irrigation regimes. Physical measurements, using 14 C-2-chloroethyl phosphonic acid ( 14 C-CEPA) at pH 6.3 indicated 60% degradation within 5 h at 40° C.

Gummosis in tulips under the influence of ethephon
Scientia Horticulturae, 1989Abstract The formation of gums and gum-like substances in bulb scales, stem tissue and perianth leaves of tulip cultivars ‘Apeldoorn’ and ‘Oxford’ was found to occur after the application of lanolin paste containing 1 or 5% 2-chloroethylphosphonic acid (ethephon), 0.2% indole-3-acetic acid (IAA) or both ethephon and IAA.

Spring Wheat and Barley Responses to Ethephon
Agronomy Journal, 1988AbstractEthephon [(2‐chloroethyl) phosphonic acid] has recently been introduced in North America as a regulator to control lodging in cereals. A 3‐yr study (1983‐1985) was conducted to determine how widely grown spring wheat (Triticum aestivum L.) and spring barley (Hordeum vulgare L.) cultivars in the North Central United States responded to ethephon.

The authors describe a gas chromatographic method for determing Ethephone residues. Studies on the residual behaviour of Ethephon on sweet cherries showed that the fruits contained 0.88, 1.45 and 1.83 p.p.m. of Ethephon after applications of 0.05, 0.075 and 0.1% Flordimex mixture, respectively.

Effects of ethephon on apomixis in Kentucky bluegrass
2020Apomixis is asexual reproduction via seed. This mode of reproduction can be exploited when an improved genotype is identified, as it can be fixed and reproduced clonally. The problem becomes identifying these novel, improved genotypes. Temporarily disabling apomixis would be an ideal approach to breeding by providing a higher proportion of hybrids to ...

The potential uses of ethephon in apple growing
Annals of Applied Biology, 1975ABSTRACTThe effects of ethephon on growth, fruit bud formation and abscission in apple will be discussed in relation to the possible use of this chemical in orchards. It is possible, for example, to accelerate the ripening of fruit on trees and yet avoid abscission effects by combining ethephon with other growth regulators.

Flue-cured tobacco seedlings at three ages were grown with three rates of fertilizer and the upper leaves were sprayed with 0, 50 and 100 mg per plant of ethephon. Ethephon treatment lowered the agronomic indices and produced leaves with a darker base color and less green (or more red) hues than the check treatment.

INFLUENCE OF ETHEPHON ON FLUE-CURED TOBACCO
Canadian Journal of Plant Science, 1977Ethephon (2-chloroethylphosphonic acid) was applied to flue-cured tobacco plants subjected to variations in cultural regime and harvesting technique to determine its influence on maturation, yield and quality. The response to ethephon treatment was evident in ripe or nearly ripe leaves after 3 days.
