General description

α-tert-Butyl-β-(4-chlorobenzyl)-1H-1,2,4-triazole-1-ethanol is a known plant growth regulator which is utilized to inhibit the alternate bearing habit of mango (Mangifera indica L.).

Application

α-tert-Butyl-β-(4-chlorobenzyl)-1H-1,2,4-triazole-1-ethanol may be used as a reference standard for the determination of the analyte in:
  • Apple juice samples by matrix solid-phase dispersion (MSPD) and gas chromatography-mass selective detection (GC-MSD) with electron impact (EI) ionization.
  • Processed fruits and vegetables by miniaturized extraction-partition and liquid chromatography-electrospray tandem mass spectrometry (LC-ESI-MS/MS) equipped with multiple reaction monitoring (MRM) detection.
  • Crops and soya grains by LC-ESI-MS/MS with MRM detection.

Drought is responsible for considerable yield losses in agriculture due to its detrimental effects on growth. Drought responses have been extensively studied, but mostly on the level of complete plants or mature tissues. However, stress responses were shown to be

• Downregulation of hydroxycinnamoyl CoA: shikimate hydroxycinnamoyl transferase (HCT) in alfalfa (Medicago sativa) reduces lignin levels and improves forage quality and saccharification efficiency for bioethanol production. However, the plants have reduced stature. It was previously reported that HCT-down-regulated Arabidopsis have

The phytohormones gibberellic acid (GA) and abscisic acid (ABA) antagonistically control seed germination. High levels of GA favor seed germination, whereas high levels of ABA hinder this process. The direct relationship between GA biosynthesis and seed germination ability need further

Seed germination is a complex process regulated by intrinsic hormonal cues such as abscisic acid (ABA) and gibberellin (GA), and environmental signals including temperature. Using pharmacological, molecular and metabolomics approaches, we show that supraoptimal temperature delays wheat seed germination through
