The Agronomy Website of Dr. agr. Volker Kleinhenz features two publications which cover water use of bamboo based on calculation of water-use potential and its' validation through empirical field studies. Phnom Penh, Cambodia (PRWEB) November 18, 2011 The paper on "Estimating water usage of bamboo" is based on the tremendous requirement for information about water usage of bamboo. Commercial producers of bamboo seek figures for selecting suitable locations for plantations and estimating...

How plants space out the pores through which they breathe The way in which plants space out the pores through which they breathe depends on keeping a protein active during stem cell growth, according to John Innes Centre scientists. Plant pores, called stomata, are essential for life. When they evolved about 400 million years ago, they helped plants conquer the land. Plants absorb carbon dioxide through stomata and release oxygen and water vapour as part of the Earth's carbon and water...

By Stuart Wolpert, UCLA The size of leaves can vary by a factor of 1,000 across plant species, but until now, the reason why has remained a mystery. A new study by an international team of scientists led by UCLA life scientists goes a long way toward solving it. In research federally funded by the National Science Foundation, the biologists found that smaller leaves are structurally and physiologically better adapted to dry soil because of their distinct vein systems. The research will be...

As carbon dioxide levels have risen during the last 150 years, the density of pores that allow plants to breathe has dwindled by 34 percent, restricting the amount of water vapor the plants release to the atmosphere, report scientists from Indiana University Bloomington and Utrecht University in the Netherlands in an upcoming issue of the Proceedings of the National Academy of Sciences (now online).In a separate paper, also to be published by PNAS, many of the same scientists describe a model...

Purdue University researchers have found a genetic mutation that allows a plant to better endure drought without losing biomass, a discovery that could reduce the amount of water required for growing plants and help plants survive and thrive in adverse conditions. Plants can naturally control the opening and closing of stomata, pores that take in carbon dioxide and release water. During drought conditions, a plant might close its stomata to conserve water. By doing so, however, the plant also...

The researchers decided to embark on this study in order to find out which mechanisms are used by plants when they extract water from very dry or somewhat inhospitable land. "In the case of mangrove swamps, for example, the plants are able to extract freshwater from a saltwater environment, despite the fact that the osmotic pressure should make quite the opposite happen", explains Professor Jos© Luis P©rez Díaz, who studies this type of relatively unknown...

A tiny, little-understood plant pore has enormous implications for weather forecasting, climate change, agriculture, hydrology, and more. A study by scientists at the Carnegie Institution's Department of Global Ecology, with colleagues from the Research Center Jlich in Germany, has now overturned the conventional belief about how these important structures called stomata regulate water vapor loss from the leaf"“a process called transpiration. They found that radiation is the driving...

The world is a cooler, wetter place because of flowering plants, according to new climate simulation results published in the journal Proceedings of the Royal Society B. The effect is especially pronounced in the Amazon basin, where replacing flowering plants with non"“flowering varieties would result in an 80 percent decrease in the area covered by ever"“wet rainforest. The simulations demonstrate the importance of flowering"“plant physiology to climate regulation in...

Working to develop heartier, better-adapted crops for southern U.S. Dr. Daniel Leskovar, a Texas AgriLife Research plant physiologist at the Texas AgriLife Research and Extension Center in Uvalde, has been investigating ways to help vegetable plants make a less stressful transition from the greenhouse to the field. "This research can aid in the successful production and possibly even the further profitability of some vegetable crops by producing high-quality, more adaptive plants that will...

Through a recent modeling experiment, a team of NASA-funded researchers have found that future concentrations of carbon dioxide and ozone in the atmosphere and of nitrogen in the soil are likely to have an important but overlooked effect on the cycling of water from sky to land to waterways.The researchers concluded that models of climate change may be underestimating how much water is likely to run off the land and back into the sea as atmospheric chemistry changes. Runoff may be as much as...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
