1. Postharvest quality of ‘Brookfield’ apple field-treated with naphthalene acetic acid alone or combined with other growth regulators
ABSTRACT The Gala cultivars represent about 65% of the Brazilian apple production, however, it has a short harvest period, making necessary to use technologies that anticipate or delay fruit maturation. A widely used technology is the preharvest application of growth regulators. The objective of this investigation was to evaluate the effect of preharvest app

2. Use of 2,4-D in Mixture with Ethephon and Calcium Carbide in Pineapple Crop
RESUMO: O ácido 2-cloroetilfosfônico (ethephon) e o carbureto de cálcio são usados para induzir e sincronizar a floração da cultura do abacaxi. Alguns produtores têm utilizado, em associação com esses indutores do florescimento, o herbicida 2,4-D. Essa prática baseia-se na hipótese de que o 2,4-D atua como regulador de crescimento, aumentando o ta

3. Seasonality and chemical elicitation of defense oleoresin production in field-grown slash pine under subtropical climate
Oleoresin is a key defense strategy of advanced gymnosperms, based on the combination of a complex anatomical structure of resin ducts and elaborate terpene biochemistry. Given the vast array of oleoresin economic applications in the chemical, pharmaceutical, agrochemical, and biofuel industries, translating factors that regulate terpene biosynthesis into hi

4. ÁCIDO 2-CLOROETILFOSFÔNICO NO RALEIO DE AMEIXEIRAS EM PÓS FLORADA
Fruit thinning is one of the main practice to produce good quality fruit today. It promotes a balance between vegetative growth and production, increases fruit size and avoids alternation of production. Thinning can be done during flowering, but its often done later after fruit set, which can be defined best fruiting. Manual thinning of large number of plant

5. Effect of paclobutrazol on germination and metabolism of ethylene in seeds of Stylosanthes humilis H.B.K. / Efeito do paclobutrazol na germinação e no metabolismo do etileno em sementes de Stylosanthes humilis H.B.K.
Germination of non-dormant seeds of Townsville stylo (Stylosanthes humilis HBK), a tropical annual forrage legume was decreased by the growth retardant paclobutrazol (PBZ) [(2RS, 3RS)-1-(4-chlorophenyl)-4,4-dimethyl-2-(1H-1,2,4- triazol-1-yl)pentan-3-ol] suspensions. This effect was reverted by 2-chloroethylphosphonic acid, an ethylene-releasing substance, a

6. Effects of Ethylene and 2-Chloroethylphosphonic Acid on the Ripening of Grapes
The effects of ethylene gas, 2-chloroethylphosphonic acid, and the auxin, benzothiazole-2-oxyacetic acid, on the ripening of grapes (Vitis vinifera L.) was investigated. Ethylene hastened the start of ripening of Doradillo grapes when it was aplied for 10 days starting midway through the slow growth phase. 2-Chloroethylphosphonic acid applied to Shiraz grape

7. The Hormone Content of Ripening Grape Berries and the Effects of Growth Substance Treatments
Berries on field-grown Vitis vinifera cv. Doradillo were treated at different times during stage II with benzothiazole-2-oxyacetic acid or 2-chloroethylphosphonic acid, and measurements were made of their growth and hormone content. The concentration of ethylene was low during stage II and declined as berries ripened. Both 2-chloroethylphosphonic acid and be

8. Sex Expression in Cucumber Plants as Affected by 2-Chloroethylphosphonic Acid, Ethylene, and Growth Regulators
The effects of 2-chloroethylphosphonic acid (Ethrel), ethylene, and some growth retardants on sex expression of cucumber plants (Cucumis sativus L.) were investigated, with the use of a monoecious cultivar (Improved Long Green) which has a strong tendency toward maleness.

9. (2-Chloroethyl)phosphonic Acid Promotes Germination of Immature Spores of Ceratopteris richardii Brongn. 1
Freshly collected spores of strain Hn-n of Ceratopteris richardii Brongn. require storage for several months before attaining maximum germination rate. Treatments using (2-chloroethyl)phosphonic acid increased germination rate in freshly collected spores and decreased germination rate in older spores.

10. Kinetic Studies of the Thermal Decomposition of 2-Chloroethylphosphonic Acid in Aqueous Solution
The decomposition of 2-chloroethylphosphonic acid in aqueous solution has been studied at pH values from 6 to 9 and at temperatures in the 30 to 55 C range. The rate of decomposition is estimated from the rate of formation of ethylene. The rate is proportional to the concentration of the phosphonate dianion and is independent of the hydroxyl ion concentratio

11. Inhibition of Cottonseed Germination with Abscisic Acid and Its Reversal
Germination of cottonseed (Gossypium hirsutum L.) was inhibited by abscisic acid. Inhibition was greater when seeds were soaked in abscisic acid for 5 hours and dried prior to germination than when abscisic acid was applied in the germination medium. (2-Chloroethyl)phosphonic acid, gibberellic acid, and kinetin partially overcame the inhibitory action of abs

12. Biogenesis of some antibiotics in the presence of 2-chloroethylphosphonic acid.
2-Chloroethylphosphonic acid (CEPA) affected both the growth of and antibiotic production in Streptomyces aureofaciens, S. griseus, S. antibioticus, and Penicillium citrinum. Streptomyces strains seemed to be more sensitive to the presence of CEPA in the medium than did the fungus. A decrease in both growth and antibiotic production was observed with a conco
