A next level of analysis is to measure the growth allocation: what is the increase in total biomass of a plant, and to what extent is the increase due to growth of leaves, of stems and of roots. In young plants, growth allocation is often quite similar to the actual biomass allocation.
A crescograph is a device for measuring growth in plants. It was invented in the early 20th century by Jagadish Chandra Bose. The Bose crescograph uses a series of clockwork gears and a smoked glass plate to record the movement of the tip of a plant (or its roots). It was able to record at magnifications of up to 10,000 times through the use of ...
Arc Auxanometer. An auxanometer (Gr. auxain = "to grow" + metron= "measure") is an apparatus for measuring increase of growth in plants. [1]In case of an arc-auxanometer (see picture), there is a thin cord fixed to the plant apex on one end and a dead-weight on the other with a pointer indicating against an arc scale.
These key measurements are used for estimation of carbon sequestered in the plants. Forest structure measurement is needed for establishment of allometric equations. Tree allometry establishes quantitative relations between some key characteristic dimensions of trees ( usually fairly easy to measure ) and other properties (often more difficult ...
Equations used to describe plant size over time are then often expolinear [15] or sigmoidal. [16] [17] 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.
Biomass partitioning is the process by which plants divide their energy among their leaves, stems, roots, and reproductive parts.These four main components of the plant have important morphological roles: leaves take in CO 2 and energy from the sun to create carbon compounds, stems grow above competitors to reach sunlight, roots absorb water and mineral nutrients from the soil while anchoring ...
The biomass that is used as input materials consists of recently living (but now dead) organisms, mainly plants. [2] Thus, fossil fuels are not regarded as biomass under this definition. Types of biomass commonly used for bioenergy include wood, food crops such as corn, energy crops and waste from forests, yards, or farms.
Leaf sensor technology developed by AgriHouse indicates water deficit stress by measuring the turgor pressure of a leaf, which decreases dramatically at the onset of leaf dehydration. Early detection of impending water deficit stress in plants can be used as an input parameter for precision irrigation control by allowing plants to communicate ...
