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: = . = .
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.
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 ...
Plant stress measurement is the quantification of environmental effects on plant health. When plants are subjected to less than ideal growing conditions, they are considered to be under stress . Stress factors can affect growth, survival and crop yields.
Similar growth stages of each plant species are given the same BBCH code. Each code has a description and important growth stages have additional drawings included. The first digit of the scale refers to the principal growth stage. The second digit refers to the secondary growth stage which corresponds to an ordinal number or percentage value.
Originally developed for growth modelling, it allows for more flexible S-shaped curves. The function is sometimes named Richards's curve after F. J. Richards , who proposed the general form for the family of models in 1959.
A leaf area index (LAI) expresses the leaf area per unit ground or trunk surface area of a plant and is commonly used as an indicator of the growth rate of a plant. LAI is a complex variable that relates not only to the size of the canopy, but also to its density, and the angle at which leaves are oriented in relation to one another and to ...
The Gompertz curve or Gompertz function is a type of mathematical model for a time series, named after Benjamin Gompertz (1779–1865). It is a sigmoid function which describes growth as being slowest at the start and end of a given time period.
