Rice, generally classified as a typical glycophyte, often faces abiotic stresses such excessive drought, high salinity, prolonged submergence, cold, and temperature, which significantly affects growth, development, ultimately, grain yield. Among these negative impacts of factors in rice production, salinity stress is major constraint, followed by drought. There considerable research on the use ...

background: cardiovascular system is a very importantorgan that plays a vital role in tissue function. in farm animals,the growth and high milk production depends on function ofcardiovascular system. objectives: cardiovascular health inhigh and low-yielding dairy cows was investigated. methods:fifty 4-year-old high- yielding holstein dairy cows and fifty 4-year-old low- yielding holstein dairy ...

Saline to freshwater invasions have become increasingly common in recent years. A key hypothesis is that rates of freshwater invasions have been amplified in recent years by increased food concentration, yet this hypothesis has remained unexplored. We examined whether elevated food concentration could enhance freshwater tolerance, and whether this effect evolves following saline to freshwater i...

soil and water salinity are the main agricultural problems in arid and semi arid areas in the world and iran. in order to investigate salinity tolerance of kochia, two experiments were conducted in a completely randomized design with four replications, seven levels of salinity (0, 10, 20, 30, 40, 50 and 60 ds m-1) and two growth stages (planting and early seedling) with gradually salinity appli...

Results of laboratory and field studies have demonstrated that salinity influences the accumulation of copper. The present study is, to our knowledge, the first to examine the effect of salinity on copper accumulation in a teleost fish across a comprehensive range of salinity from freshwater to seawater. This was done in an effort to identify potential target tissues and differences in chemical...

Dekoko (Pisum sativum var. abyssinicum) is one of the most important food legumes grown in south Tigray and north Wollo, northern Ethiopia. It is one among the most important food legumes in terms of protein content. It grows mixed and alone with many cereal crops growing in north Ethiopia. This study was conducted in 2015/2016with the objective of selecting adaptable and relatively high yieldi...

BACKGROUND Biodiesel production from marine microalgae has received much attention as microalgae can be cultivated on non-arable land without the use of potable water, and with the additional benefits of mitigating CO2 emissions and yielding biomass. However, there is still a lack of effective operational strategies to promote lipid accumulation in marine microalgae, which are suitable for maki...

A study was performed using 6 × 6 F1 diallel population without reciprocals to assess the mode of inheritance of pod yield and related traits in groundnut with imposed salinity stress. Heterosis was found for pod number and yield. Data on general and specific combining ability (gca and sca) indicated additive and nonadditive gene actions. The gca: sca ratios were much less than unity suggesting...

in order to study and determine the most effective traits, drought tolerance indices and identify tolerant genotypes in terminal drought stress on the cowpea, an experiment was carried out based on an augment design in two separate conditions in the karaj farm, faculty of agriculture, tehran university in 2009. drought stress was imposed by cutting irrigation after flowering against normal irri...
