Pea (pisum in Latin) is a pulse, vegetable or fodder crop, but the word often refers to the seed or sometimes the pod of this flowering plant species. Carl Linnaeus gave the species the scientific name Pisum sativum in 1753 (meaning cultivated pea).
The most distinctive characteristics that allow rhizobia to be distinguished apart are the rapidity of their growth and the type of root nodule that they form with their host. [60] Root nodules can be classified as being either indeterminate, cylindrical and often branched, and determinate, spherical with prominent lenticels.
A selection of dried pulses and fresh legumes. Legumes (/ ˈ l ɛ ɡ j uː m, l ə ˈ ɡ j uː m /) are plants in the family Fabaceae (or Leguminosae), or the fruit or seeds of such plants.
Peanut flower. The peanut is an annual herbaceous plant growing 30 to 50 centimetres (12 to 20 in) tall. [9] As a legume, it belongs to the botanical family Fabaceae, also known as Leguminosae, and commonly known as the legume, bean, or pea family. [1]
Peas also contain nearly 7% of your daily amount of iron, Derocha adds, which is a good reminder "because often people think (iron has to come from) liver, organ meats or a steak, but it doesn't ...
Root nodules apparently have evolved three times within the Fabaceae but are rare outside that family. The propensity of these plants to develop root nodules seems to relate to their root structure. In particular, a tendency to develop lateral roots in response to abscisic acid may enable the later evolution of root nodules. [21]
This map shows the sites of domestication for a number of crop plants. Places, where crops were initially domesticated, are called centers of origin.. This is a list of plants that have been domesticated by humans.
Most trees begin life with a taproot, [3] but after one to a few years the main root system changes to a wide-spreading fibrous root system with mainly horizontal-growing surface roots and only a few vertical, deep-anchoring roots. A typical mature tree 30–50 m tall has a root system that extends horizontally in all directions as far as the ...
