To investigate the effect of ethephon on control of male flowers in melon, a split plot experiment, with randomized complete blocks design and three replications, was conducted in Agricultural and Natural Resources Research Center of Varamin, Iran, during 2005-2006. The main factor included three levels of plant growth stage (3-leaf, 6-leaf and early reproductive stage) and sub-plots included f...

the aim of the present investigation was to study the growth, yield and yield components of maize (zea mays l.) single cross 704 under different levels of irrigation, plant density, and ethephon in southern iran where this particular crop has not yet been studied in detail. a field experiment was performed in the 2004 5 growing season at the experimental farm of the college of agriculture, shir...

This study was performed to evaluate the role of ethylene stress, ethylene inhibitors and action treatments on longevity of potted-carnation flowers. For this purpose, first, potted-carnation flowers were pretreated with different concentrations of amino-oxyacetic acid (AOA), benzyladenine (BA) and 1-methylcyclopropene (1-MCP). Then, ethephon (as stress treatment) was sprayed on the pretreated ...

The high level of physiological fruitlet abscission in litchi (Litchi chinensis Sonn.) causes severe yield loss. Cell separation occurs at the fruit abscission zone (FAZ) and can be triggered by ethylene. However, a deep knowledge of the molecular events occurring in the FAZ is still unknown. Here, genome-wide digital transcript abundance (DTA) analysis of putative fruit abscission related gene...

Ethephon (2-chloroethylphosphonic acid) was applied to single cluster greenhouse tomato crops (1000 ppm) at the green mature stage of fruit development or when 35% of the plants had fruits at the breaker stage. Fruits were harvested at the pink stage. Untreated fruit were harvested from 95 to 116 days after sowing whereas fruit from the green mature ethephon treatment were harvested from 92 to ...

The paper aimed to study the influence of naphthalene acetic acid (NAA) and ethephon on total phenols, flavonoids and tannins as a function of seasonality in Echinodorus grandiflorus plants. The experiment used adventitious plantlets from the flower stem with 4 to 5 leaves, planted in 10-liter pots. The leaf spray treatments applied were: control, NAA 100 mg L -1 , and ethephon 100 mg L -1 . Tr...

The aim of this study was conducted to subchronic toxic effects separate and combined using of maleic hydrazide and ethephon in female mice. Treatment group divided into 9 groups according to chemicals’ doses and compared with controls. Three separate maleic hydrazide doses (100-200-400 mg/kg/day, in feed) and ethephon (50-100-150 mg/kg/day, in water) were given alone and in combination during ...

BACKGROUND Chemicals that are commonly used for artificial ripening and to increase the shelf life of fruits and vegetables are ethylene, ethane, calcium carbide, and ethephon. The present study was conducted to study the effect of ethephon on the morphometry of rat liver. METHODS Ethephon was administered by oral gavage tube to 10 adult Wistar albino rats at a dose of 200 mg/kg body weight/d...

Fruitlet abscission of mango is typically very severe, causing considerable production losses worldwide. Consequently, a detailed physiological and molecular characterization of fruitlet abscission in mango is required to describe the onset and time-dependent course of this process. To identify the underlying key mechanisms of abscission, ethephon, an ethylene releasing substance, was applied a...

a study was conducted on six years old trees of almond, shahroud cv. (no. 18), in a three-year trial (2002-04) at mashhad agricultural research station. the experiment was done on the basis of completely randomized desigh with four replications. in the first and second years of the experiment, ethephon was sprayed in 15 and 20 days before the common time of harvesting, respectively. the concent...
