Scarification is often done mechanically, thermally, and chemically. The seeds of many plant species are often impervious to water and gases, thus preventing or delaying germination. Any process designed to make the testa (seed coat) more permeable to water and gases is known as scarification.
In the past, the grass was a staple food of Native Americans, especially when the maize crop failed, and for non-agricultural tribes. Seed of the ricegrass was gathered and ground into meal or flour and made into bread. Since 2000, the ricegrass has been cultivated in Montana and marketed under the trade name Montina as a gluten-free grain. [11]
This is facilitated by the bulliform cells located at the base of the V-shaped notch which swells and makes the leaf uncurl when filled with water. [8] This plant is highly adaptive in sand, and can withstand burial for more than one year. Unlike other plants which will die in sand, marram grass will elongate its leaves when it is buried by sand.
Seeds are applied to tilled soil using a high pressure hose. The seeds are likely mixed into a water-based spray that often contains mulch, fertilizer, lime, or other substances that promote seed growth. [5] This technique is usually used to plant grass, but it is not uncommon to see it being used to plant wildflowers or groundcovers.
Seeds are placed in a medium such as vermiculite, peat, or sand and refrigerated in a plastic bag or sealed container. [1] Soaking the seeds in cold water for 6–12 hours before placing them in cold stratification can cut down on the amount of time needed for stratification, as the seed needs to absorb some moisture to enable the chemical ...
Gentian seedlings in a plant nursery. Plant propagation is the process by which new plants grow from various sources, including seeds, cuttings, and other plant parts. Plant propagation can refer to both man-made and natural processes. Propagation typically occurs as a step in the overall cycle of plant growth.
Ammophila breviligulata (American beachgrass or American marram grass) is a species of grass native to eastern North America, where it grows on sand dunes along the Atlantic Ocean and Great Lakes coasts. Beachgrass thrives under conditions of shifting sand, sand burial, and high winds; it is a dune-building grass that builds the first line of ...
Drip irrigation or trickle irrigation is a type of micro-irrigation system that has the potential to save water and nutrients by allowing water to drip slowly to the roots of plants, either from above the soil surface or buried below the surface. The goal is to place water directly into the root zone and minimize evaporation.
