Juvenile plants often appear different from the adult form as the branchlets are covered with tomentum until they mature and become darker. [ 9 ] During the spring to early summer, karo produce fragrant burgundy red flowers that are around 10cm long with long stalks and are borne in terminal umbels meaning that they grow in clusters, similar to ...
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: = . = .
Medicinal plants, also called ... was estimated to be US$60 billion per year and growing at the rate of 6% per annum. ... depending on the growth conditions of plants ...
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 ...
In young plants, growth allocation is often quite similar to the actual biomass allocation. But especially in trees, there may be a high yearly turnover in leaves and fine roots, and a low turnover in stems, branches and thick roots. In those cases, the allocation of growth and the final biomass allocation may diverge quite strongly over the years.
Like FvFm, Y(II) represents a measurement ratio of plant efficiency, but in this case, it is an indication of the amount of energy used in photochemistry by photosystem II under steady-state photosynthetic lighting conditions. For most types of plant stress, Y(II) correlates to plant carbon assimilation in a linear fashion in C 4 plants.
The neoplastic roots produced by A. rhizogenes infection have a high growth rate (compared to untransformed adventitious roots), as well as genetic and biochemical stability. Currently the main constraint for commercial utilization of hairy root culture is the development and up-scaling of appropriate ( bioreactors ) vessels for the delicate ...
Chloride is one of the 16 elements essential for plant growth. Because it is supposedly needed in small quantities for healthy growth of plants (< 50–100 μM in the nutrient media), chloride is classified as a micronutrient. [80] Aluminum: Variable micronutrient: Al 3+ 0: 10 [70] Al 2 (SO 4) 3: Essential for some plants (e.g. peas, maize ...
