From past to the present, cultural, medicinal, landscape and culinary use of junipers has contrib­uted it being one most widely distributed woody plants in world. Therefore, is so important that finding appropriate production methods obtain quality seedlings line with usage area. In present study, was tried determine best conditions applications on propagation by cuttings three juniper taxa inc...

Creeping bentgrass putting greens experience quality decline during summer due to heat and drought stress in U.S. transition zone other areas with similar climate. Plant biostimulants have been used improve turfgrass tolerance abiotic stress. This study was designed investigate the effect modes of action humic acid (HA) based on turf quality, root viability, hormone metabolism creeping The two ...

A simple and reliable high-performance liquid chromatographic method that uses photodiode array detection was developed for the simultaneous determination of 12 native and synthetic plant hormones, i.e., plant growth regulators (PGRs), in fertilizers, such as 1-naphthol, 2,4-dichlorophenoxyacetic acid, 4-(2,4-dichlorophenoxy)butyric acid, 4-chlorophenoxyacetic acid, indole-3-acetic acid, 4-(3-i...

The Arabidopsis chy1 mutant is resistant to indole-3butyric acid, a naturally occurring form of the plant hormone auxin. Because the mutant also has defects in peroxisomal -oxidation, this resistance presumably results from a reduced conversion of indole-3-butyric acid to indole-3-acetic acid. We have cloned CHY1, which appears to encode a peroxisomal protein 43% identical to a mammalian valine...

nut (Juglans regia L.) shoots by subculturing the shoots on rooting medium containing agar and 3 mg l indole-3-butyric acid (IBA) for 7 days in darkness. Changes in the concentrations of endogenous free indole-3-acetic acid (IAA), indole-3acetylaspartic acid (IAAsp) and free polyamines were determined during culture on root-inducing medium. In extracts of whole shoots, the concentration of free...

in this work, a green, simple and highly efficient procedure for the synthesis of bis(indolyl)methanes is described. the condensation of indoles with carbonyl compounds catalyzed by citric acid in water affords bis(indolyl)methanes in high yields and relatively short reaction times. the advantages of this method are using of water as a low cost solvent and efficient recyclability of the catalyst.
