Let’s know about Herbaceous Plants. Grass plants are vascular plants that have no persistent woody stems above ground, [1] [2] including many perennials , and almost all annuals and biennials . [3] Herbivorous plants include graminoids , forbs , and ferns . [4] Forbes is generally defined as herbaceous broadleaf plants, [5] while graminoids are grass-like plants that include true grasses, sedges, and rushes. [6] [7]In some botanical sources, the noun “herb” refers to a “plant that does not produce a woody stem”, and the adjective “herb” means “herb-like”, which refers to the plant. Refers to the parts of the plant that are green and soft in texture. “. [8] [9] The word “herb” also has other meanings in cooking, medicine, and other fields.
Herbaceous plants are often low-growing plants, which differ from woody plants such as trees, and have soft green stems that lack lignification and their above-ground growth is short- lived and often seasonal in duration. Is. [11] In contrast, non-herbivorous vascular plants are woody plants that have above-ground stems, which survive any dormant season, and grow shoots from above-ground parts the following year – These include trees , shrubs , vines and vines . _ wooden bamboo, Banana plants are also considered herbaceous plants because the stem does not contain true woody tissue.
Types of herbaceous plants
Herbivorous plants include plants that have an annual, biennial or perennial life cycle. Annual herbaceous plants die off completely at the end of the growing season or when they flower and fruit, and then new plants grow from seed. [13] Herbivorous perennials and biennials may have stems that die off at the end of the growing season, but some parts of the plant can grow from season to season (for biennials, until the next growing season, when they flower). live below or near it. and die). Roots , a caudate (a thick part of the stem at ground level) or a variety of underground stems , such as bulbs , corms , stolons , rhizomesAnd new growth develops from living tissue on or under the ground, including tubers . Examples of herbaceous biennials include carrot , parsnip and common ragwort ; Herbivorous perennials include potatoes , peony , hosta , mint , most ferns , and most grasses.
Habit and habit
Some relatively fast-growing herbaceous plants (especially annuals) are pioneer, or early-successor species. Others make up the main vegetation of many stable habitats, for example in the ground layer of forests, or in naturally open habitats such as grasslands, salt marshes or deserts. Some habitats, such as grasslands and prairie and savanna, [14] are dominated by aquatic environments as well as herbaceous plants such as ponds, rivers, and lakes.
Some herbaceous plants can grow larger, such as the genus Musa , to which the banana belongs.
The age of some herbaceous perennial plants can be determined by herbicide, analysis of annual growth rings in the secondary root xylem. Herbivorous plants do not perennially produce above-ground structures using lignin, a complex phenolic polymer deposited in the secondary cell wall of all vascular plants. The development of lignin during vascular plant development provided mechanical strength, rigidity and hydrophobicity to secondary cell walls, allowing plants to grow longer and transport water and nutrients over long distances within the plant body . Since most woody plants are perennials with a long life cycle that takes longer and more resources (nutrients and water) to be able to produce continuously living lignified woody stems, they are open and grown as herbs. They are not able to colonize dry land.
Herbs are the catalyst for surface dew, [16] [17] which is the main type of precipitation in dry climates and climates and is essential for the survival of vegetation, [18] [19] that is, in arid regions, herbaceous plants. They are a generator of rainfall and the basis of an ecosystem. Most of the water vapor that turns into dew comes from the air, not the soil. [20] [21] The longer the herb is, the more dew it produces, [22] [23] so shortening the herb makes watering necessary. For example, if you cut grass frequently and quickly in a dry area without watering, desertification occurs, as shown here.
