Description
Technical Field
The invention relates to the technical field of tissue culture, in particular to a culture medium and a culture method for Sorbus sophorae.
Background
Sorbus sophorae is an ancient Chinese catalpa variety, and the trunk of the Chinese Sorbus sophorae is very similar to that of the Sorbus sophorae, so the Chinese Sorbus sophorae is called as Sorbus sophorae. The Chinese scholartree is noble, simple and practical, and is a good tree species capable of transmitting wealth to offspring. Sophora japonica Makino is a high-quality and rare wood facing the seed culture in the north of the Yangtze river, grows in the Shandong peninsula and the Lu-Wen south, and is slow and rare. The general adult trees are 60 years to 80 years old. The wood has the characteristics of clear texture, fine and uniform structure, decay resistance, no deformation, no cracking and no peculiar smell. According to the records of the history of the Ming and Qing dynasties, Sorbus pohuashanensis is the preferred wood for making appliances at that time and is appreciated by the world population. The invented furniture made of wood not only possesses the characteristics of practicality, appreciation and value-keeping increment of all redwood furniture, but also possesses the quality which can not be reached by redwood due to soil and water inadequacy, desiccation, deformation and slotting. In addition, the rosewood furniture in the current market has mixed fish eyes, and the authenticity is difficult to distinguish. Antique furniture made of Sorbus pohuashanensis is popular among middle-aged and elderly people and successful people due to the characteristics of firmness, durability, nature, environmental protection and the like.
Sorbus sophorae is a precious variety of mountain ash trees and has other uses. Ancient books are also documented. For the medical purpose, Ben Cao gang mu states that pounding catalpa leaves to affected sores and swelling, boiling and washing pus and blood. "the decoction of the root and bark of catalpa bungei can be used for treating baldness, fistula and swelling by external application; eating, recorded in the Ming Dynasty abalone mountain's wild vegetable Bo Lu's book, the food recipe, fried flowers and oil-salt mixed food. Or sun drying, frying, and parching; used as feed, the sushi of songshi (food rough talk) is described in: the Tung catalpa bungei is immediately fat and easy to raise when being used for feeding pigs in leaves. From the ancient books, it can be seen how important the catalpa bungei plays a role in the life and production of ancient workers in China.
With the development of ecological forestry and the requirement of market economy, the mass propagation of improved varieties of Sorbus pohuashanensis becomes a problem to be solved urgently at present.
