The earliest published work on growing terrestrial plants without soil was the 1627 book Sylva Sylvarum or 'A Natural History' by Francis Bacon, printed a year after his death. As a result of his work, water culture became a popular research technique.
Underground stems are modified plant parts that derive from stem tissue but exist under the soil surface. [1] They function as storage tissues for food and nutrients, facilitate the propagation of new clones, and aid in perennation (survival from one growing season to the next). [2]
Due to the disease-free environment unique to aeroponics, many plants can be grown at higher densities (plants per square meter) compared to more traditional cultivation methods like hydroponics, soil, and Nutrient Film Technique (NFT). Commercial aeroponic systems incorporate hardware features that accommodate the expanding root systems of crops.
The epicotyl will expand and form the point of attachment of the shoot apex and leaf primordia or "first true leaves". Cotyledons may remain belowground or be pushed up aboveground with the growing stem depending on the plant species in question. In plant physiology, the epicotyl is the embryonic shoot above the cotyledons. In most plants the ...
Lathyrus sativus, also known as grass pea, cicerchia, blue sweet pea, chickling pea, chickling vetch, Indian pea, [2] white pea [3] and white vetch, [4] is a legume (family Fabaceae) commonly grown for human consumption and livestock feed in Asia and East Africa. [5]

As the plant embryo grows at germination, it sends out a shoot called a radicle that becomes the primary root, and then penetrates down into the soil.After emergence of the radicle, the hypocotyl emerges and lifts the growing tip (usually including the seed coat) above the ground, bearing the embryonic leaves (called cotyledons), and the plumule that gives rise to the first true leaves.
