Atmospheric aerosol particles have a significant effect on global climate, air quality, and consequently human health. Condensation of organic vapors is a key process in the growth of nanometer-sized particles to climate relevant sizes. This growth is very sensitive to the mass accommodation coefficient α, a quantity describing the vapor uptake ability of the particles, but knowledge on α of at...

African marigold, being tall enough and producing large flowers suitable for preparing garlands, is the most cultivated cultivar of marigold in Nepal. Besides, pinching other improved cultural techniques, a number chemicals, hormones phyto-hormones are tested found to impart varying response marigold. This review has its importance standardizing type concentration plant growth regulators Online...

This study investigated the effects of magnetite nanoparticles (MNPs) various sizes (10.77, 20.5, and 29.3 nm), different concentrations (0.5, 1, 2 ppm) on growth production active constituents in Ginkgo biloba L callus. The best medium for callus proliferation was MS supplemented with 1 ppm naphthalene acetic acid (NAA), Kinetin, 0.5 MNPs a size 10 nm, which gave maximum fresh weight percentag...

A systematic study on the distortion of a naphthalene ring was performed using steric repulsion between peri-substituents at 1- and 8-positions. The introduction bromo groups into methyl 1,8-dimethylnaphthalene enhanced to distort ring. X-ray crystallography revealed that 1,8-bis(bromomethyl)naphthalene had vertical with 11.0° dihedral angle (α) which disturbed coplanarity On other hand, 1,8-bi...

Cariniana rubra Miers (Lecythidaceae), popularly known as "jequitibá-vermelho'', is a large Brazilian tree whose bark is used in infusion and decoction for the treatment of inflammatory conditions. This study aims to assess the anti-inflammatory, antinociceptive, and antipyretic effects of Cariniana rubra methanolic stem bark extract (EM Cr) using experimental animals. Anti-inflammatory activit...

Anaerobic naphthalene degradation by a sulfate-reducing enrichment culture was studied by substrate utilization tests and identification of metabolites by gas chromatography-mass spectrometry. In substrate utilization tests, the culture was able to oxidize naphthalene, 2-methylnaphthalene, 1and 2-naphthoic acids, phenylacetic acid, benzoic acid, cyclohexanecarboxylic acid, and cyclohex-1-ene-ca...

The present study, "Effect of plant growth regulators on growth, fruit setting, and quality guava (Psidium guajava L.) in meadow orchard," was carried out the years 2021–2022, at Central Research Farm, Department Horticulture, Sam Higginbottom Institute Agriculture & Sciences, Prayagraj (U.P.). Ten treatments made up experiment with: control, three concentrations gibberellic acid (GA3) 75, ...

In order to study the germination and growth of pepper seeds, a factorial experiment based on a completely randomized design with three replications was conducted. The first factor was consisting of five cultivars of pepper (Marquiza, Cadia, California Wonder, California Wonder 310 and California Wonder 300) and the second factor was gibberellic acid with three levels (0 as control, 250 and 500...

The present investigation was carried out at Horticultural Research Institute, Ayub Agricultural Faisalabad during 2017-2019 to evaluate the effect of different growth regulators on root induction Date palm suckers. There were six treatments i.e., T0 (Control), T1 (Indol butyric Acid (IBA) @2000 ppm), T2 (IBA@4000 T3 (Naphthalene Acetic (NAA) T4 (NAA@3000), T5 (IBA@2000 ppm + NAA@2000 ppm). Gro...

Sunflower (Helianthus annuus) is a crop of increasing importance as source seed oil and proteins; nonetheless, the number studies on sunflower tissue culture somewhat limited. The development competent in vitro direct organogenesis protocol involves important basic steps regeneration. In our study, chemically sterilized seeds were planted induction media, 52.54 % germination efficiency was foun...
