The simulated growth of plants is a significant task in of systems biology and mathematical biology, which seeks to reproduce plant morphology with computer software. Electronic trees (e-trees) usually use L-systems to simulate growth. L-systems are very important in the field of complexity science and A-life.
Agronomic studies often focus on the above-ground part of plant biomass, and consider crop growth rates rather than individual plant growth rates. Nonetheless there is a strong corollary between the two approaches. More specifically, the ULR as discussed above shows up in crop growth analysis as well, as: = . = .
This group is the more common of the two, especially outside Asia; names such as napa cabbage, dà báicài (Chinese: 大白菜, "large white vegetable"); Baguio petsay or petsay wombok (); Chinese white cabbage; "wong a pak" (Hokkien, Fujianese); baechu (Korean: 배추), wongbok; hakusai (Japanese: 白菜 or ハクサイ) and "suann-tang-pe̍h-á" (Taiwanese) [2] usually refer to members of ...

Shape descriptor, fine-scale margin, and texture histograms are given. 1600 Text Classification 2012 [305] [306] J. Cope et al. Soybean Dataset Database of diseased soybean plants. 35 features for each plant are given. Plants are classified into 19 ...
Modelling is essential in theoretical production ecology. Unit of modelling usually is the crop, the assembly of plants per standard surface unit.Analysis results for an individual plant are generalised to the standard surface, e.g. the leaf area index is the projected surface area of all crop leaves above a unit area of ground.
Typical Jarvis type-equation of r sc adopted in BAITSSS is shown below, R c-min is the minimum value of r sc, LAI is leaf area index, f c is fraction of canopy cover, weighting functions representing plant response to solar radiation (F 1), air temperature (F 2), vapor pressure deficit (F 3), and soil moisture (F 4) each varying between 0 and 1.
The rate at which a population increases in size if there are no density-dependent forces regulating the population is known as the intrinsic rate of increase.It is = where the derivative / is the rate of increase of the population, N is the population size, and r is the intrinsic rate of increase.
This model can be generalized to any number of species competing against each other. One can think of the populations and growth rates as vectors, α 's as a matrix.Then the equation for any species i becomes = (=) or, if the carrying capacity is pulled into the interaction matrix (this doesn't actually change the equations, only how the interaction matrix is defined), = (=) where N is the ...
