The effects of pulse treatment with gibberellin A3 (GA3), silveT thiosulfate complex (STS), and with or without sucrose on chlorophyll degTadation and vase life of cut flowers of Narcissus tazetta var. chinensis were investigated. The 20-hr pulsing treatment with STS extended the vase life of cut fiowers of IVL tazetta var. chinensis, Pulse treatments with GA3 delayed degradation of chlorophyll...

This review of Photochemistry and Photobiology summarizes articles published in 2010, and highlights progress in the area of photosensitization. The synthesis of conjugated photosensitizers is an area of interest where increasing water solubility has been a goal. Targeting infrared sensitizer absorption has been another goal, and relates to the practical need of deep tissue absorption of light....

essential oils from aerial parts of mentha spicata, was obtained by steam destillation using a clevenger-type system. these oils were screened for antibacterial and anti-candida albicans activity using bioautographic method. a fiel experiments was laid out in agricultural research farm, city namin, ardabil province, iran in 2013. experiment was conducted in a randomized complete block with seve...

ABSTRACT: Overall plant growth and microbial biomass can be effected by dust accumulation. The chloroform fumigation-extraction method was used to evaluating the effect of cement dust pollution emitted from Kurdistan cement factory on soil microbial biomass carbon. Chlorophyll content (a, b and total) of plants species was measured in different distance from cement factory. Mic...

Spinning of cellulosic fibers requires the prior dissolution cellulose. 3-Alkyl-1-methylimidazolium ionic liquids have proven to be suitable solvents for that purpose, but degradation cellulose in spinning dope can severe. Suitable stabilizers are therefore required prevent degradation, do not adversely affect spinnability or long-term yellowing behavior fibers. A group twelve renewables-based ...

The material composition of a group Rodovetri, hand-painted animation cels, made in the 1950s and 1960s for Italian television, has been determined by Flash Py-GC-MS, Thermally assisted Hydrolysis Methylation-(Py-)GC-MS GC-MS investigations, where, pyrolysis applications, pyrolyzer is connected septum-less to GC inlet. condition selected cels was generally poor (yellowing, exudation, warping, c...

Tocopherols, a subclassof tocochromanols that contain a phytol attached to the head group, act as antioxidants to protect lipids from oxidative damage, a particularly important function in chloroplasts and for seed longevity (reviewed in Maeda and DellaPenna, 2007). One pathway for tocopherol biosynthesis involves de novo synthesis from geranylgeranyl-diphosphate; the other pathway uses phytols...
