In barley (Hordeum vulgare) leaves in which the water balance was not hampered, kinetin and abscisic acid effected the well documented decrease and increase, respectively, in RNase activity. When the plants were exposed to water shortage, leaf-water saturation deficit increased steadily, with kinetin enhancing and abscisic acid retarding the rise. Under drought, the pattern of hormonal effects ...

in the present study ethanol and water extracts of 15 seaweeds, dictyota dichotoma var. velutricata, dictyota indica, iyengaria stellata, padina pavonia, sargassum swartzii, sargassum variegatum, stoechospermum marginatum, stokeyia indica, jolyna laminarioides, caulerpa taxifolia, halimeda tuna, ulva fasciata, ulva lactuca, solieria robusta, and melanothamnus afaqhusainii, were evaluated for th...

The antimicrobial efficacy of methanol and water extracts of seeds of the plant Swietenia macrophylla (Family: Meliaceae) was evaluated against selected pathogenic bacterial strains (Bacillus cereus MTCC 430, Klebsiella penumoniae MTCC 109, Pseudomonas aeruginosa MTCC 424, Escherichia  coli MTCC 443, Staphylococcus aureus MTCC 96, Salmonella typhimurium MTCC 98, Micrococcus luteus MTCC 106...

the influence of water deprivation on potted grape (vitis vinifera l.) was investigated. leaf mass area (lma) and biochemical responses, including chlorophyll, total protein, peroxidase activity, soluble carbohydrates, photosynthesis and stomatal conductance were assessed in leaves of ‘sahani’ and ‘bidane sefid’ grape cultivars subjected to progressive drought (soil water potentials of: -0.2, -...

Propolis has traditionally been used in curing infections and healing wounds and burns. Current researches have shown that propolis has antibacterial, antifungal and antiviral actions however, the pharmacological activity of propolis is highly variable depending on its geographic origin. There have been few studies on the effects of Iranian propolis on the oral microorganisms. In this in-vitro ...

this study examined if pre-germination altered the water content and water activity, contents of phytate, total phenolic, (±)-catechin, quercetin and total antioxidant capacity of almond  (prunus dulcis)kernel. raw almond kernels were submerged for 15 hours in water, 0.02 mol dm-3 phosphate buffer solution (ph 5.0) and 0.02 mol dm-3 phosphate buffer solution (ph 7.0) at 25 and 40ºc, respectivel...

Introduction Conclusions References Tables Figures Back Close Abstract Introduction Conclusions References Tables Figures Back Close Abstract Water activities of a series of polyol/water systems were measured with an AquaLab dew point water activity meter at 298 K. The investigated polyols with carbon numbers from n=2−7 are all in liquid state at room temperature and miscible at any molar ratio...

the aim of this study was to develop a microemulsion system as a medium for laccase-catalyzed reactions. phase behavior studies were conducted by constructing partial pseudo-ternary phase diagrams for systems comprising of cetyltrimethylammonium bromide (ctab), various organic solvents as the oil phase (i.e., hexane, cyclohexane, heptane, octane, isooctane, toluene, isopropyl myristate), two co...
