Aerial adventitious roots: examples of ivy and maize<\/strong>
<\/span><\/p>

1\/ Ivy :<\/strong><\/strong>\u00a0The plant climbs quickly and develops aerial adventitious roots from its stem which are used to firmly attach itself to its support, either a plant (tree) or a mineral (wall).\u00a0They are spiked roots. On the other hand, an ivy plant has also subterranean roots that extend into the soil, attaching the plant to the ground and absorbing water and mineral from the soil.<\/p>

Below photographs of an ivy growing at the surface of a maple tree. On the right part of the plant attached to the tree trunk by adventitious roots (red arrows). Ivy is an epiphyte growing on another plant without parasitizing.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

2\/\u00a0Adventitious roots of maize<\/strong>.
<\/span><\/span><\/p>

The root system of maize is composed of an embryonic root system (primary root or radicle and the seminal roots) and of a post embryonic root system which is made up by shoot-borne roots, formed at successive nodal structures of the shoot. Shoot \u2013 borne roots formed in soil are designated crown roots, while shoot \u2013 borne roots initiated above soil level are termed brace roots. The shoot borne \u2013 roots make up the major proportion of the adult maize root system.\u00a0
Brace roots are illustrated on the pictures below. These specialized adventitious roots growing from the stem into the soil help the tall corn plants that lack woody tissues and secondary growth to stay upright.<\/p>

On the photograph at the bottom right two levels of adventitious roots are evident (blue and red arrows).\u00a0These specialized adventitious roots growing from the stem into the soil help the tall corn plants that lack woody tissues and secondary growth to stay upright.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
