selenium is a metalloid that it is antioxidant characteristics is proved for humans, animals and plants. however, some plants are known as hyper accumulators for selenium and sometimes seems to be useful for growth of some plants. in this paper, we have studied the effect of different selenium concentrations on growth and morpho-physiological characteristics of spinach. seeds of spinach were ge...

effects of water stress and fusarium oxysporum f. sp. lycoperseci (fol) on the growth of tomatoes were studied in a greenhouse experiment. treatments consisted of five levels of water stress (1, 3, 5, 7 and 9 day irrigation intervals). infested soil consisting of 400 chlamydospores g1 of fol and non infested soil were used. experiments arranged in a completely randomized design with 8 replicati...

Study was conducted on 20 dogs of different breeds and age, of Bhilai area naturally infested with Rhipicephalus Sanguineus ticks. Dogs with moderate to severe tick infestations were treated with ivermectin pour on @ 1ml/10kg body weight. In the present study ivermectin pour on was found to be 100 percent effective against naturally occurring tick infestation in dogs.

Preventive measures against soil-borne diseases need to be implemented before cultivation because very few countermeasures are available after the development of diseases. Some soils suppress soil-borne diseases despite the presence of a high population density of pathogens. If the suppressiveness of soil against soil-borne diseases may be predicted and diagnosed for crop fields, it may be poss...

This study was undertaken to compare the levels of ascorbic acid, vitamin C, flavonoids, nitrate, and oxalate in 27 spinach varieties grown in certified organic and conventional cropping systems. Liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-(ESI)MS/MS) of methanolic extracts of spinach demonstrated 17 flavonoids, including glucuronides and acylated di- and triglyco...

The 70-kD heat-shock proteins (HSP70s) are encoded by a multigene family in eukaryotes. In plants, the 70-kD heat-shock cognate (HSC70) proteins are located in organellar and cytosolic compartments of cells in most tissues. Previous work has indicated that HSC70 proteins of spinach (Spinacia oleracea) are actively synthesized during cold-acclimating conditions. We have isolated, sequenced, and ...

Water spinach (Ipomoea aquatica Forsk, cv. Bamboo-Leaf) grown in aerated nutrient solution in greenhouse was treated with various levels of nickel, copper, zinc, chromium, cadmium, manganese, arsenic, aluminum, and lead. Injury symptoms caused by these metals were compared with each other. Among these metals, only nickel produced specific symptoms of along-vein necrosis on leaves and stems. Lea...

METHODS An ectoparasiticide containing spinosad was evaluated as an oral formulation for cats. Two European laboratory studies and a European multicentre field efficacy and safety study assessed the use of a chewable tablet formulation of spinosad at a dose range of 50-75 mg/kg for treatment and control of flea infestations on cats. RESULTS The studies with experimentally infested cats consis...

BACKGROUND The postharvest quality and shelf life of spinach are greatly influenced by cultural practices. Reduced spinach shelf life is a common quandary in the Salinas Valley, California, where current agronomic practices depend on high nitrogen (N) rates. This study aimed to describe the postharvest fracture properties of spinach leaves in relation to N fertilization, leaf age and spinach cu...
