Researchers calculated the response of apple fruit quality to sprays of zinc sulfate and sugar alcohol zinc to determine whether continuing to supply zinc to trees could increase the fruit quality of "Fuji" and "Gala" apples. Results showed that, although the apple trees showed no zinc deficiency symptoms and the leaf zinc nutrition was at a low level, continuing zinc sprays throughout the growing cycle was necessary to increase fruit quality.
Effects of LEDs on leaf lettuce: Mixture of blue and red lights recommended to enhance lettuce quality, yield
Scientists determined the effects of blue and red LED ratios on leaf shape, plant growth, and the accumulation of antioxidant phenolic compounds of a red leaf lettuce and a green leaf lettuce cultivar. They determined that red LED light promoted growth and that blue LED light was good for phenolics accumulation rather than growth, thus concluding that a combination of red and blue light is essential for cultivation of leafy vegetables like lettuce.
Researchers monitored environmental data inside shadehouses with full covering of red, blue, pearl, and black nets in central Florida over 12 months. The report documents the different environmental modifications inside the structures, which will help predict or interpret specific plant responses, including photosynthetically active radiation and air temperatures.
Researchers tested the hypothesis that herbivores -- and their plant diets -- have evolved to have greater number of Tas2r bitter taste receptor genes in their genomes than omnivores or carnivores. Their analyses supported the hypothesis, showing vertebrates can also be classified as herbivores, carnivores, or omnivores based on their Tas2r genetic profile.
Scientists have used a DNA sequencing technique to identify mutations present across thousands of cancer cells in three patients with leukemia. The technique can identify the founding mutations from which a tumor evolved, and uses computer software to map the cancer's family tree. The findings could be used to identify the key mutations that occur early in a tumor's development, allowing doctors to use targeted treatments more effectively.
Researchers are closing in on finding an effective bait to get ahead of the destructive spread of mountain pine beetle, which is now killing not only lodgepole pine forests, but jack pine.
New research has found that the number of pests and disease outbreaks in trees and forests across the world has been increasing. There is growing concern that aspects of globalization - in particular, high volumes and new forms of trade - may increase the risk of disease spreading and provide opportunities for genetic reassortment which can enhance pathogenicity (the ability of an organism to cause disease).
Scientists have discovered how cells in the stems of seedlings use blue light to grow towards the light. During earlier research the discovery was made that the cells in the seedling stems responded to blue light used in the microscope. The scientists have now discovered how the blue light causes small structures in the cell, the microtubules, to grow perpendicular to their normal growth direction.
Researchers have identified a rain forest microbe that feasts on the lignin in plant leaf litter, making it a potential ally for the cost-effective production of advanced biofuels.
Researchers have found that tree cover actually causes snow to melt more quickly in warm, Mediterranean-type climates around the world. Alternatively, open, clear gaps in the forests tend to keep snow on the ground longer into the spring and summer.
Arabidopsis plants that only reach half their normal height have a mutation in the biosynthesis of the plant growth factor gibberellin.
Agricultural researchers have developed a new technique to aid in the development of defenses against diseases threatening food crops worldwide.
Inside every plant cell, a cytoskeleton provides an interior scaffolding to direct construction of the cell's walls, and thus the growth of the organism as a whole. Environmental and hormonal signals that modulate cell growth cause reorganization of this scaffolding. New research provides surprising evidence as to how this reorganization process works, with important evidence as to how the direction of a light source influences a plant's growth pattern.
An Australian research team has investigated the threat horse riding poses to the ecology of national parks around the world. And it seems there's a growing problem in horse dung.
Scientists have found the oldest fossil depicting copulating insects in northeastern China.
Researchers are delving into the mysterious world of algae to find better ways to put these organisms to use.
A new study of re-growing tropical forests has concluded that plant biodiversity takes longer to recover than carbon storage following major disturbances such as clearance for farming.
When water is scarce, Ecuador laurel trees ramp up their investment in a syrupy treat that sends resident ant defenders into overdrive, protecting the trees from defoliation by leaf-munching pests.
New research published this week sheds light on how desert plants gain nutrients they desperately need -- even in the driest circumstances.
Biologists have discovered fundamental rules for leaf design that underlie the ability of plants to make leaves that vary enormously in size.
