2Department of Genetics & Plant Breeding‚ Bangladesh Agricultural University 1Japan 2Bangladesh 1. Introduction Plants are sessile and sensitive organisms that inevitably encounter a variety of abiotic stresses in nature. Abiotic stresses such as salinity‚ drought‚ heavy metal toxicity and extreme temperatures are critical factors that reduce crop yields by more than 50% worldwide (Wang et al.‚ 2003). The scenario is even more aggravated by the predicted forthcoming global changes in climate‚ foreseen

balance of who survives and who perishes. In April 2012‚ Diablo was plunged into emergency shutdown because of jellyfish clogging up the seawater intake pipes for the cooling system. Jellyfish have caused many dozens of such shutdowns at nuclear power plants‚ coal-fired power plants‚ and desalination plants -- pretty much any type of industry that draws seawater. In a healthy ecosystem‚ fish are superior competitors and predators over jellyfish. But the things we humans do -- we fish‚ we pollute

Hoping to postpone the inevitable‚ their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor’s death. We’ll prepare solutions of salt water to represent the sea‚ and we’ll cut up slices of potato to represent

MBG-7 personnel also checked on the swirling seawater–alarmed residents likened it to boiling water– reportedly seen 50 meters from the shoreline of Barangay Looc. Looc is 3 kilometers from Cambuang. Abraham Lucero Jr.‚ MGB-7 senior science research specialist‚ said they went to check the swirling seawater last Monday but failed to see it because of high tide. Lucero said the earthquake might have affected the shallow aquifer

The Rocky Shore Experiment Research Question: How does type of substrate affect the variation of species and vegetation as you move away from the seashore at a Rocky Shore? Hypothesis: As we get further away from the seashore‚ there would be a decrease in the number of species and vegetation found. Also‚ the type of substrate will have a major affect on the biodiversity. Background Information: A rocky shore is an intertidal area of seacoasts where solid rock predominates. Rocky shores are

They all have adapted to the location that they are found in‚ like warm or cold water. #6 Other abiotic factors An abiotic factor means organisms that help the ecosystem overall. In the marine biome salinity is a factor‚ which means how salty the ocean is. The animals and plants adapt to the salinity. The sunlight also helps because it gives the plants energy‚ the process of photosynthesis‚ and ultimately making food for itself. The temperature‚ which allows the plants and animals to inhabit a specific

concentrations of saline inhibit germination? What does the higher concentrations of saline do to the P. vulgaris seed? Are seeds tolerant to higher concentrations of saline? “All soil contains salts‚ many of which are essential nutrients for plants. Salinity occurs when soluble salts (usually NaCl) are elevated in soil and water. Every continent is affected by salinized soil and water; approximately 7% of the world’s land area.” (Nerissa Hannink‚ 2005). “But why should we care about how a plant

Water Crisis in UAE Introduction Water crisis refers to the situation where the available water within a geographical location cannot meet the water needs of the population in that location. This prevalent situation has drawn considerable attention in most countries due to its severity to humanity. Because of the tripling of the population in the 21st century‚ the demand for water has remained considerably higher than the available clean and safe water. Despite the fact that the earth is covered
