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 ...
The equation for exponential mass growth rate in plant growth analysis is often expressed as: = Where: M(t) is the final mass of the plant at time (t). M 0 is the initial mass of the plant. RGR is the relative growth rate. RGR can then be written as:
Arundo donax is a strong candidate for use as a renewable biofuel source because of its fast growth rate and its ability to grow in different soil types and climatic conditions. A. donax will produce an average of three kilograms of biomass per square metre (12 tons per acre/year) once established. [ 40 ]
Researchers predict an average yield of 14.6 dry tonnes per hectare per year for miscanthus on marginal land in China, 12.6% below expected average yield on arable land. They calculate that miscanthus on marginal land in China can produce 31.7 EJ (exajoule) of energy annually, [18] an amount equivalent to 39% of the country's 2019 coal consumption.
Pachycormus is a monotypic genus of flowering plants in the cashew family commonly known as the Baja elephant tree, torote blanco, or copalquín. [3] The single species Pachycormus discolor is endemic to the Baja California peninsula , with three varieties.
Cenchrus purpureus, synonym Pennisetum purpureum, [1] also known as Napier grass, elephant grass or Uganda grass, is a species of perennial tropical grass native to African grasslands. [2] It has low water and nutrient requirements, and therefore can make use of otherwise uncultivated lands.
Chemical plant cost indexes are dimensionless numbers employed to updating capital cost required to erect a chemical plant from a past date to a later time, following changes in the value of money due to inflation and deflation. Since, at any given time, the number of chemical plants is insufficient to use in a preliminary or predesign estimate ...
The plants can be damaged if temperatures fall below 10 °C (50 °F) for more than a few days. The root tuber is typically planted close to the surface. The first signs of growth will appear in 1 to 3 weeks. The adult plant will need a minimum of at least 1 m 2 (11 sq ft) of space for good growth.
