Transpiration of water from the crop occurs mainly at the leaves, through specialised openings (called stomata) that allow the passage of carbon dioxide into the leaf (and of oxygen out of the leaf) for photosynthesis.
Finally, even if arable fields are characterized by stochastic conditions, a specialized species could persist temporally, for example, with dormant diaspores that would wait for optimal environmental conditions e.g., high relative summer air humidity for arable bryophyte species [ 21] or each time a favourable crop occurs in the rotation [ 22].
Maximum daily N uptake by the potato crop occurred between 55 and 65 days after planting, coinciding with the onset of the tuber bulking stage.
In the state of Florida, some damage to the cotton crop occurred in Escambia County.
In addition, cider apples more often display biennial bearing (Dapena et al. 2005), that is, with crop occurring only every two years.
It is essentially an upland area of undulating meadows, but some cultivation of crops occurs in the southwest and along the River Soar valley in the north.
Under current E.U. rules, authorization for GM crops occurs at the continental level, after a health and environmental safety assessment by the European Food Safety Agency in Parma, Italy.
Under the current E.U. system, authorization for GM crops occurs at the European level, after a health and environmental safety assessment by the European Food Safety Agency EFSAA) in Parma, Italy.
Double and even triple cropping occurs in some areas throughout the year with relatively warm, moist (rainfall: 2,580 mm/year), sub-tropical (latitude 31°N) conditions (JMA, 2012).
A strong association between duck, paddy rice, and double cropping occurs in Southeast Asia (Gilbert et al., 2007), and an identical association is apparent in Bangladesh and surrounding regions of northeastern India (Hossain et al., 2005).
FA biosynthesis within developing seeds of oleaginous crops occurs in the plastids, with the resulting FAs being subsequently released into the cytosol predominantly as oleic acid (18 1 cis Δ9; OA), along with minor amounts of palmitic (16:0) and stearic (18 0) acids in the form of acyl-Coenzyme A (CoA) [ 10, 11].
