introduction lentil is one of the major legume with protein content about 28% where is cultivated in different regions of iran, especially in arid and semi-arid regions with low or variable rainfall. in these regions abiotic stresses such as heat of the around the end of growing season, drought stress in early and late within the season and salt stress alone or together have a large negative im...

light is never being distributed homogeneously and it forms a gradient over biomass. the unidirectional nature of light gives rise to a vertical gradient of light intensity as a function of depth. the maximum depth of the light zone suitable for phytoplankton photosynthesis is designated as the euphotic depth. this study was designed to test the hypothesis of mixing depth of phytoplankton and i...

An estimated 260 million indigenous peoples live in Asia. Most of them inhabit forested uplands where a large number of them practice shifting cultivation, which is also called as swidden cultivation or rotational farming. For them, shifting cultivation is not merely a technique of farming; it is their ways of life. Government policies and laws have attempted to limit or outright ban shifting c...

A microcosm cultivation-based method was set up to investigate the growth of ammonia-oxidizing archaea (AOA), isolated from a water sample acquired at a depth of 50 m from the northern basin of Lake Kivu. For this purpose, both CARD-FISH and qPCR targeting of archaeal 16S rRNA and amoA genes were used. Archaeal cell growth at the end of the 246-day microcosm experiment accounted for 35% of the ...

Weed infestation of durum wheat was determined in the systems of conventional tillage(CT), reduced tillage (RT) and herbicide tillage (HT). Cultivations measures performed after theharvest of the previous crop included shallow ploughing (at a depth of 10-12 cm) and pre-winterploughing (25-30 cm) in the CT system; only field cultivation (10-15 cm) in the RT system; andspraying with glyphosate (R...

In a spatial thermal gradient, Caenorhabditis elegans migrates toward and then isothermally tracks near its cultivation temperature. A current model for thermotactic behavior involves a thermophilic drive (involving the neurons AFD and AIY) and cryophilic drive (involving the neuron AIZ) that balance at the cultivation temperature. Here, we analyze the movements of individual worms responding t...

Simplified cultivation technologies for rice have become increasingly attractive in recent years in China because of their social, economical and environmental benefits. To date, several simplified cultivation technologies, such as conventional tillage and seedling throwing (CTST), conventional tillage and direct seeding (CTDS), no-tillage and seedling throwing (NTST), no-tillage and direct see...

Microbial communities in coastal subsurface sediments are scarcely investigated and have escaped attention so far. But since they are likely to play an important role in biogeochemical cycles, knowledge of their composition and ecological adaptations is important. Microbial communities in tidal sediments were investigated along the geochemical gradients from the surface down to a depth of 5.5 m...

Before the development of egg mediums, serum was used extensively as a medium in the cultivation of tubercle bacilli. Eastwood in 1907 reported that horse, bovine, dog, and pig serums supported good growth of stock cultures of human and bovine tubercle bacilli and also served well as isolation mediums. Since the introduction of egg mediums there has been little use of serum as a medium in itsel...
