Any houseplant owner knows that changes in the amount of water or sunlight a plant receives can put it under immense stress. A dying plant brings certain disappointment to anyone with a green thumb.
What holds true for meadows would seem to apply to arable land, too: mixed cultures are more fruitful than monocultures.
Two new studies of green algae — the scourge of swimming pool owners and freshwater ponds — have revealed new insights into how these organisms siphon carbon dioxide from the air for use in photosynth...
该研究首先利用响应面法优化了HPLC-DPPH的条件,并在此条件下筛选出了黄花补血草中7种具有抗氧化作用的化合物。利用HPLC-MS技术鉴定出黄花补血草中具有抗氧化作用的化合物为杨梅酮-3-O-β-D-(6“-O-没食子酰基)-吡喃葡萄糖苷、杨梅素-3-O-葡萄糖苷、杨梅苷、圣草素-7-O-葡萄糖苷、杨梅酮、圣草素和高圣草素。
When soil nitrate levels are low, plants suffer nitrogen (N) deficiency but when the levels are excessive, soil nitrates can pollute surface and subsurface waters.
The genus Allium (Family: Alliaceae) is the most important among the bulbous vegetable crops. characterization of Alliums based on phenotypic traits is influenced by the environment and leads to biase...
The drivers of tropical deforestation have shifted in the early 21st century to hinge on growth of cities and the globalized agricultural trade, a new large-scale study concludes. The observations sta...
The geometry and modeling parameters of an artificial neural network (ANN) have significant effects on its predictive performance efficiency. The optimal geometry of an ANN is problem-dependent. Altho...
Three of the most important crops produced in the United States—corn, soybeans and cotton—are predicted to suffer declines of as much as 80 percent if temperatures continue to rise with manmade climat...
Actual evapotranspiration from typical Mediterranean crops has been assessed in a Sicilian study area by using surface energy balance (SEB) and soil-water balance models. Both modelling approaches us...
In the framework of simplified water balance models devoted to irrigation scheduling or crop modelling, the relative transpiration rate (the ratio of actual to maximal transpiration) is assumed to dec...
Some effects in the biosphere from the Total Solar Eclipse of 29 March 2006 were investigated in field crops and marine zooplankton. Taking into account the decisive role of light on plant life and pr...
This work proposes a Hidden Markov Model (HMM) based technique to classify agricultural crops, exploring information of temporal image sequences from TM and ETM+ /Landsat sensors. It endeavours to ...
3 May 2007,While the United States has vastly increased funding for homeland security and the military, two food safety experts warned that gaps remain in the nation’s ability to adequately protect it...
This study aimed to examine the fermentation quality of a tropical Elephant grass (Pennisetum purpuereum) and temperate Italian ryegrass (Lolium multiflorum) forages ensiled additive of fermented juic...
