The performance of ethephon (Proxy) on seedhead suppression ‘Innovation’ zoysiagrass was evaluated during the 2019–2020 growing season in Manhattan, KS. Treatments Proxy applied a single autumn application at 5 fl. oz./1,000 ft2 multiple dates between August 28 and November 26, 2019. Seedhead ranged from 15% (application 1) to 82% (applied September 4). Dates 4 October 3 were optimum window for...

The calcium content and distribution across the abscission zones of (2-chloroethyl) phosphonic acid-treated bean (Phaseolus vulgaris L. var. Contender) leaves were lower and not uniformly distributed as compared to the control. Calcium chloride-treated bean leaves had a higher calcium content, with more calcium localized in the potential abscission layer. Ethephon treatment promoted abscission ...

Complex defense signaling pathways, controlled by different hormones, are involved in the reaction of plants to a wide range of biotic and abiotic stress factors. We studied the ability of salicylic acid, jasmonate (JA), and ethylene (ET) to induce systemic defense in rice (Oryza sativa) against the root knot nematode Meloidogyne graminicola. Exogenous ET (ethephon) and JA (methyl jasmonate) su...

Abstract The experiment was conducted to study the effect of ethephon and moisture stress in different growth stages on yield, its components, water consumption efficiency safflower (Gilla) variety. This carried out during winter season 2021-2022, 11/24/2021, Al-Bulatif area, which is 3 km from governorate center, fields a farmer Al-Muthanna Governorate. It implemented that using split-section ...

"Aging" of excised cotyledons plus the top part of the hypocotyl of Amaranthus tricolor seedlings was carried out by washing in distilled H(2)O for varying periods. This led to increased betacyanin accumulation during the subsequent 24-hour induction period in the presence of tyrosine and Na(+) + K(+) phosphate. Endogenous accumulation as well as that dependent on added benzyladenine and on add...
