Excellent hybrid varieties of Taxus mairei
1. Twenty thousand 3-year-old seedlings of Taxus mairei were introduced from Canada, which were mainly used in large-scale production of paclitaxel. The growth of Taxus in China is slow, the content of taxol is relatively low, and it is listed as a national first-class protected plant as a rare tree species. The taxol content in the branches and leaves of Taxus mairei is about 0.02%, and the content in the bark is 0.03%-0.04%, which is 2-3 times of the 60-year-old bark of Taxus mairei, and the growth rate is 3 times that of Taxus mairei. With unknown trunk

Rapid propagation of Taxus mairei
Because it contains extractable anti-cancer drugs, Taxus mairei has become an important medicinal material in the country. The demand for seedlings is increasing. It is difficult to meet the needs of production by traditional cutting propagation alone. Generally, only one batch can be cultivated in a year, while at least 5-6 batches can be cultivated by using non-test-tube cloning technology, and the survival rate and the quality of seedlings are greatly improved. What is more important is that the fast-growing seedlings can be transplanted, planted and developed throughout the year. Generally, 3-5 cm long leafy branches are used as in vitro materials.

Taxus mairei
Taxus, also known as yew, Latin name: TaxusMedia, is a yew evergreen coniferous plant, is listed as a rare and endangered species in the world, is a national first-class protected plant, known as "plant gold". The paclitaxel extracted from it has high anticancer activity and can treat a variety of cancers. The American Cancer Institute believes that paclitaxel is the most effective anticancer drug for human beings in the future. Taxus mairei is a hybrid variety with fast growth rate, high taxol content and strong adaptability to the environment.

Clone yew "squeeze" to produce anti-cancer king
Professor Sichuan University demonstrated the unique transgenic cloning technology of plants, and the next step is to focus on anti-cancer plants. "We have successfully cloned two plants with different genes using cloning transgenic technology, and the next step is to apply this technology to the cloning of the anticancer drug paclitaxel." A few days ago, Professor Wang Li of the Plant Research Office of the School of Life Sciences of Sichuan University demonstrated to reporters the cloning and transgenic technology that is rarely known to outsiders. A plant was cloned from the leaves. In the laboratory, Professor Wang pointed to a green plant about 20 centimeters high and said: "

Rapid Propagation of Anticancer Plant Hybrid Taxus chinensis
Hybrid Taxus mairei 8502 is one of more than ten cultivated strains of Taxus mandshurica Taxusmedia. Its rapid growth and wide adaptability are better than other strains and can be planted in most areas of our country. Taxusmedia is one of the yew approved by FDA to extract paclitaxel, an anticancer drug. The taxol content in the branches and leaves of the 5-year-old Taxus mairei was higher than that of the natural yew bark grown for 70 ~ 80 years. A wild yew, including domestic varieties.

Why the leaves of Magnolia grandiflora dried up and fell off
There is a letter from a reader in Tianjin: two pots of grafted magnolia were bought four years ago, but they used to grow well. Yellow leaves appeared in the winter in the flower cellar last year, and then gradually developed into half of the leaves scorched and fell off. After coming out of the cellar in May this year, the new leaves became semi-dry soon, and it was even more serious from July to August. It was thought to be caused by fungi, but it was ineffective after medication. What is the cause of this, please? What rescue measures should be taken? A: there may be the following reasons for the drying up and shedding of your Magnolia leaves: first,

Propagation and cultivation of Magnolia lanceolata
Purple magnolia, also known as Xinyi, originated in central China. Like warm, humid and sunny environment, more cold-resistant, but not resistant to drought and salinity, afraid of flooding, requires fertile, well-drained sandy loam. Reproduction: commonly used ramets, striping and sowing reproduction. Ramet can be carried out in spring and autumn, the mother plant with dense branches can be dug out and planted separately, and the root system and short branches can be trimmed. Striping, selected from 2012 branches, can be propagated by piling soil or burying strips in early spring. Sowing, seed collection in September, sand storage in winter, spring sowing the following year, and germination 20-30 days after sowing. Cultivation: transplanting

Breeding Management of Magnolia Magnolia (1)
This variety likes light and is not resistant to severe cold. Like fertile, moist and well-drained soil, grow poorly on too dry and alkaline soil and clay. The root is fleshy and afraid of stagnant water. Ramet, striping, cutting and sowing can be used to propagate ramet in spring and autumn. Mother plants with dense branches can be dug out and planted respectively, and roots and short branches can be trimmed. The well-growing plants can be selected, and the 1-2-year-old branches with a thickness of 0.5 mi 1 cm are used as strips. If there is a branch, it can be pressed on the branch. The time of pressing is from February to March in early spring. After the pressure, it took root in the same year, and
