The effects of application calcium-containing natural fertilizer on the functional state tea plant were studied. Application calcium resulted weakening negative high temperatures and water deficiency due to an increase in its heat resistance (on average by 30 - 40%), catalase activity 5 10 %), as well adaptive rearrangement pigment ratio increasing content carotenoids, chlorophylls their activi...

Arabian deep-sea red shrimp Aristeus alcocki is considered to be an ideal source of pigments, especially astaxanthin, and its analogs. Extraction pigments from exoskeleton discards A. was analyzed by using organic solvents, namely, n-hexane, acetone, ethyl acetate, methanol, ethanol under cold hot conditions. A significantly greater yield obtained acetone: methanol (1:1 v/v) (10.4-10.9%) (9.3-9...

This study was conducted to determine the effects of growth regulator prohexadione calcium (Pro-Ca) and inhibitor gibberellic acid on some parameters (yield, pigment levels leaves, nutrient contents, proline, enzyme activities fruit quality) when applied at different doses (0, 15, 30, 45, 60 mg L-1). Chemicals were after transplanting seedlings. A total 12 plots including 3 plants for each dose...

Abstract Bacterial Grain Rot caused by Burkholderia glumae is an important disease of rice. In South Sulawesi, this seed-borne pathogen has been detected in several places. There were some reports from the farmers regarding rice yield loss due to disease. This study aimed isolate and characterize morpho-physiologically bacterium causing grain rot main rice-producing areas Gowa Regency, Sulawesi...

Pea is a grain legume crop commonly grown in semi-arid temperate regions. susceptible to heat stress that affects development and reduces yield. Leaf pigments surface wax canopy make the primary interaction with environment can impact plant response environmental stress. Vegetation indices be used indirectly assess performance regard pigment, biomass, water content indicate overall Our objectiv...

 Abstract Background: Transpupillary thermotherapy is a new treatment for subfoveal choroidal neovascularization which needs further evaluation. This study was aimed to evaluate the efficacy of transpupillary thermotherapy on regression of occult subfoveal choroidal neovascularization with or without pigment epithelial detachment in patients with age-related macular degeneration. Methods: In a ...

Zeaxanthin, a C40xanthophyll carotenoid, has potential biological applications in nutrition and human health. In this study we characterized carotenoid composition in 5 taxonomically related marine bacterial isolates from the genus Muricauda. The pigment was characterized using high performance liquid chromatography (HPLC) and mass spectrometry, which confirmed the presence of all-trans-zeaxant...

Chlorophyll a fluorescence quenching was studied in intact, C 0 2 fixing chloroplasts isolated from spinach. Energy-dependent quenching (qE), which is correlated with the light-induced pro­ ton gradient across the thylakoid membrane presumably reflects an increase in the rate-constant of thermal dissipation of excitation energy in the photosynthetic pigment system. The extent of qE was found to...

The purple-coloured pigment violacein, produced mainly by bacteria of the genus Chromobacterium, had attracted and increased interest owing to its important biological activities and pharmacological potential. In the present study experiments were designed to investigate the effect of different fermentation conditions on the violacein production by novel isolate Chromobacterium vaccinii CV5. Di...
