Propagation of Arthraxon hispidus (Thunb.) Makino
Arthraxon hispidus (Thunb.) Makino, commonly known as hispid carpetgrass is a perennial grass that belongs to the family Poaceae. This plant species is native to East Asia, including China, Korea, and Japan, and has been introduced to other parts of the world. Propagation is a crucial aspect of plant growth and development, and it can be accomplished through various methods.
Seed Propagation
Seed propagation of Arthraxon hispidus is one of the most commonly used methods. Seeds of this species have a hard outer shell, and pre-treatment of the seeds is essential to enhance germination. One of the most common ways of pre-treating seeds is a scarification process, which involves nicking or scratching the outer seed coat using sandpaper or a blade. Stratification is another pre-treatment procedure that involves keeping seeds in a cold environment for a specific period, usually four to six weeks. After pre-treatment, the seeds can be sown directly on the soil surface in spring or autumn. It is essential to keep the soil moist and ensure a temperature range of 20-25 °C to promote germination.
Vegetative Propagation
Vegetative propagation is another effective method of propagating Arthraxon hispidus. The plant can be propagated using vegetative parts such as stolons, rhizomes, and tillers. These parts can be separated from the parent plant and planted in a suitable growth medium. Stolons are horizontal stems that grow above the ground, while rhizomes are horizontal stems that grow underground. To propagate using stolons, one only needs to bury the stolon nodes and wait for new roots to form. Rhizomes and tillers can be divided into sections that have new growth points and planted. It is vital to ensure adequate moisture and temperature to encourage growth.
Cultural Practices
Cultural practices such as watering and fertilization can also facilitate plant propagation. It is essential to maintain adequate moisture levels in the soil during the period of growth. Soil that is too dry can cause the seeds to fail to germinate or dry out the vegetative plant parts. Proper fertilization is essential to provide essential nutrients that promote plant growth. Fertilization should be done before the growing season and during the period of active growth. The use of organic matter is also essential to improve soil nutrients and water holding capacity.
