1. The adventitious roots of the stem sections of the seedlings of M. violaceum are more prone to breeding. In the spring, the top buds of 6 cm to 8 cm are cut from the strong mother plant. If the top buds are very long, they can be cut into 1 and 2 sections with 3 sections of 5 leaves per section, and the base 1 of the branches removed. Leaf, inserted in seedbeds, seedbeds available soil, or sand and straw ash, can also be inserted in the sink. The cuttings are 6 cm to 10 PCT in diameter, and about 2/3 of the shoots are immersed in soil. The water is permeable, covered with a plastic film to keep it moist (20°C), watered frequently, and survived for 10-15 days before being transplanted with soil.
