What is the difference between tissue-cultured orchid seedlings and native seedlings?

Orchids need to meet these key points. Tissue-cultured orchid seedlings: refers to complete plants regenerated through in vitro culture, growth and development under artificial sterile conditions; the root system is relatively straight, the surface is smooth and white, and the leaves are shorter and thin. Due to the genetic effects of plant cells, phenomena such as failure to bloom, seedling collapse and faint floral fragrance are also prone to occur. Native orchid seedlings: refers to plants grown from germinated seeds; the root system generally has dragon roots, dragon eggs or bamboo nodes, but the roots are not straight and the surface is pitted, and the leaves are longer and thicker.
