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 host of Ascochyta pisi is the field pea (Pisum sativum L.). Ascochyta pisi also infects 20 genera of plants and more than 50 plant species including soybean, sweet pea, lentil, alfalfa, common bean, clover, black-eyed-pea, and broad bean. [2] Field pea is an annual, cool season legume that is native to northwest and southwest Asia.
Pods of the edible-podded pea, including snap peas, do not have a membrane and do not open when ripe. At maturity, the pods grow to around 4 to 8 centimetres (1 + 1 ⁄ 2 to 3 inches) in length. Pods contain three to nine peas. The plants are climbing, and pea sticks or a trellis or other support system is required for optimal growth.
These have five sepals and five petals and are irregular. The uppermost petal is known as the "standard", the lateral two as the "wings" and the lowest two are joined to form the "keel". There are ten stamens and a single carpel. The fruit is a flat brown pod containing up to twelve seeds. This plant flowers in July and August. [2]
A child holding an edible pod pea in Kenya. Snow peas, along with sugar snap peas and unlike field and garden peas, are notable for having edible pods that lack inedible fiber [11] (in the form of "parchment", a fibrous layer found in the inner pod rich in lignin [12]) in the pod walls. Snow peas have the thinner walls of the two edible pod ...
In contrast to the tiny flowers, the fruit of this species is a very large, flattened, woody pod or capsule, measuring about 1–1.2 m (3 ft 3 in – 3 ft 11 in) long and 12 cm (4.7 in) wide. They are usually slightly curved longitudinally, and have about 12 segments, each containing one seed.
