WOLPERT, T. J., and L. D. DUNKLE. 1980. Purification and partial characterization of host-specific toxins produced by Periconia circinata. Phytopathology 70:872-876. Host-specific toxins isolated from culture filtrates of Periconia circinata properties of polyamines. HPLC resolved each of those toxic fractions into inhibited root growth of the susceptible sorghum genotype by 50% at 1 two compou...

The present work deals with the ways of testing the compatibility of reactive dyes with cotton in different textile industries in Bangladesh. This report includes three laboratory trials that were carried out for three different reactive dyes to check the compatibility for use in a dye recipe on cotton knitted goods. In this study, Spectrophotometric analysis was conducted and the fixation of e...

introduction iran kaluts (yardang) which are considered as special models in terms of magnitude and extension have been shaped in the west part of the central lut desert. although these kaluts now are influenced by the selective windy erosion, they can be shaped through the process of wind and water erosion. the suitable environment for formation of these kaluts are the arid region together wit...

Maize leaf phosphoenolpyruvate carboxylase [PEPC; orthophosphate:oxaloacetate carboxy-lyase (phosphorylating), EC 4.1.1.311 protein-serine kinase (PEPC-PK) phosphorylates serine-15 of its target enzyme, thus leading to an increase in catalytic activity and a concomitant decrease in malate sensitivity of this cytoplasmic C4 photosynthesis enzyme in the light. We have recently demonstrated that t...

The physical properties and chemical composition of microsomal membranes were examined during a 7 day period of ice encasement in crown tissue of winter wheat (Triicum aestivum L. cv Norstar). Membrane damage, detected as an increase in microviscosity and electrolyte leakage, began between 1 and 3 days of icing, and was associated with a reduction in the recovery of microsomal membranes from st...

This experimental study was conducted to investigate the effect of treatment of composting plant leachate by a coagulation-flocculation process. The effects of different dosages of coagulant and different pH values on the coagulation processes were compared. Ferric chloride and aluminium sulphate (alum) were tested as conventional coagulants. The experimental results show that a 18% removal of ...

The pathogenicity of Diplostomum cercariae shed from two different snail species (Lymnaea. stagnalis and Radix auricularia) to rainbow trout fry (5-6 cm body length) was investigated. Thus, 1000 cercariae per fish elicited 100 % mortality within 24 h. Cercariae shed from L. stagnalis (Diplostomum pseudospathaceum) elicited higher mortality in rainbow trout compared to cercariae (Diplostomum par...

Effects of Ginkgo biloba L. extract on the seed germination, seedling growth and leaf anatomy of barley under saline conditions were studied. In parallel with concentration rise, salt stress inhibited the seed germination and seedling growth of barley. The inhibitive effect of salt on the germination and coleoptile percentage was alleviated in varying degrees, and dramatically, by Ginkgo biloba...

This paper describes the preliminary steps toward developing an in vitro model for producing pit and fissure caries. Four groups of 12 intact molars mounted in acrylic and pit and fissure areas were painted with Streptoccocus mutans-inoculated culture medium. In Group A, the bacterial inoculum was covered by agar. In Group B, carboxymethyl cellulose was used instead of agar. In Group C, agar wa...

Four nodulating annual tropical wild legumes, viz., Alysicarpus monilifer, Desmodium triflorum, Indigofera linnaei and Tephrosia purpurea from three different regions in the Western Ghats ecosystem were investigated to assess their mycorrhizal status. The response ofvesicular-arbuscular mycorrhizal (VAM) root colonization and spore number to edaphicfactors such as soil moisture, pH and availabl...
