Portulacaria afra (known as elephant bush, porkbush, purslane tree, dwarf jade and spekboom in Afrikaans) is a small-leaved succulent plant found in South Africa. These succulents commonly have a reddish stem and green leaves, but a variegated cultivar is often seen in cultivation. They are simple to care for and make easy houseplants for a ...
Kalanchoe beharensis (commonly known as elephant's ear kalanchoe, felt bush, or feltbush) is a plant species in the succulent genus Kalanchoe, and the family Crassulaceae. Kalanchoe beharensis is native to Madagascar [ 1 ] known by local names mongy , rongy and tavitavy .
Growing degree days (GDD), also called growing degree units (GDUs), are a heuristic tool in phenology.GDD are a measure of heat accumulation used by horticulturists, gardeners, and farmers to predict plant and animal development rates such as the date that a flower will bloom, an insect will emerge from dormancy, or a crop will reach maturity.
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: = . = .
Beaucarnea recurvata, the elephant's foot [4] or ponytail palm, [5] is a species of flowering plant in the family Asparagaceae. The species was native to numerous states of eastern Mexico but is now confined to the state of Veracruz. [1] [6] Despite its common name, it is not closely related to the true palms .
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.
This species indicates when it is requiring water, by the presence of green growth. From when a new growth appears from the thick stem (caudex), it can receive regular watering, up until the growth withers and dies back. This is when the plant goes into its summer dormancy. Then watering should become more rare – until the next new growth ...
