Method for grafting magnolia liliiflora to michelia alba

Abstract: The invention discloses a method for grafting magnolia liliiflora to michelia alba. The method is characterized by comprising the following steps: (1) selecting a michelia alba branch of which the age is more than 2 years and the main diameter is more than 1cm to serve as a stock, wherein the difference between the diameter of the top and the diameter of the bottom of the michelia alba branch is small, and the michelia alba branch is free of pests; (2) selecting an annual magnolia liliiflora branch to serve as a cion, wherein the length of magnolia liliiflora is from 10cm to 15cm; earthing the magnolia liliiflora branch, and then, performing patch grafting on the magnolia liliiflora branch and the michelia alba branch with a diagonal plane of 45 degrees; (3) performing conservation according to traditional tree grafting management; earthing on the magnolia liliiflora refers to paving the magnolia liliiflora flat on a nutrition matrix, covering the paved magnolia liliiflora branch with a layer of mixed soil which is 5-10cm thick, keeping the soil water content of the nutrition matrix and the soil water content of the mixed soil be 10-20 percent, earthing for 10-25 days, and then, taking out for grafting. The method disclosed by the invention is simple and feasible; compared with the traditional breeding method, the method disclosed by the invention has the advantages that the survival rate can reach more than 90 percent, the survival rate after grafting is greatly increased, the planting cost is reduced, and the economic benefit is improved.

‘Chilongzhua’ and ‘Yanzhizui’: Two Interspecific Hybrid Cultivars of Michelia

Abstract: The genus Michelia L. (Magnoliaceae) comprises 70 species of tropical or subtropical evergreen trees or shrubs distributed in Asia (Xia et al., 2008). Some of these species are well known as horticultural plants in landscape gardening (Tian, 2007; Zhang et al., 2007). Michelia crassipes Law is an evergreen shrub native to southeastern China (Xia et al., 2008) where it is widely cultivated for its purple flowers that are unique in the genus (Liu, 2004). Thus, this characteristic makes M. crassipes highly desirable in breeding new cultivars because the flowers of most species of Michelia are white or yellowy (Liu, 2004). Up to now, four cultivars have been selected or bred from M. crassipes (Gong et al., 2003; Liao, 2007). Michelia crassipes ‘Mozi’ is a commercially available selection introduced by the Hunan Province Forest Botanical Garden that has larger, dark purple flowers with a silver edge, which occurred as a spontaneous mutation on a plant growing wild in Hunan (Liao, 2007). Three cultivars, including M. ‘Yujin’, M. ‘Danxin’, and M. ‘Qinfang’, are interspecific hybrids between M. crassipes and M. yunnanensis. M. calcicola C. Y. Wu is an evergreen tree native to the subtropical limestone forests of southeastern and eastern China (Liu, 2004). It has attractive, large, yellow flowers with a size of 8 to 10 cm in diameter. Both M. crassipes and M. calcicola flower from March to May with single flowers lasting from 5 to 7 d. M. ‘Chilongzhua’ and M. ‘Yanzhizui’ are hybrids of M. crassipes and M. calcicola selected for their distinctive flower color and fragrance.

Review on pharmacological activities of Michelia alba

Abstract: This review describes the morphological, phytochemical and pharmacological properties of Michelia alba (Magnoliaceae). The genus Michelia (Magnoliaceae) consists of approximately 30 species. Michelia alba D.C. is a tall tree native to Indonesia and has been used by the native Malays in Indonesia and Malaysia for medicinal purposes. The tree producing these flowers ranges from 10 to 15 meters in height and can grow up to 20 meters if cultivated in a high-moisture area. Cracks in the stem bark are in a reticulated pattern along the trunk. Michelia alba is an annual flowering plant; generally the flowers begin to bloom in the evening, with their scent becoming widespread; the scent begins to fade in the afternoon. Gardeners usually collect the flowers twice a day: at night and at dawn. This plant was used for the treatment of fever, syphilis, gonorrhea and malaria, and was regarded traditionally as an abortive agent. The present pape r enumerates an overview of phytochemical composition and pharmacological aspects that is useful to researchers for further exploration for necessary development of this potential herb.

Anti-freezing method for michelia albe tree

Abstract: The invention discloses an anti-freezing method for a michelia albe tree, and belongs to the field of plant cultivation. The anti-freezing method for the michelia albe tree can effectively overcome the defects that the michelia albe tree is easy to freeze to death and blossom in the next year is impacted. A first plastic film layer is spread flatly, then a second plastic film layer is overlaid, the length of the plastic films is 5m, and the width of the plastic films is 3m, heat sealing is carried out on three edges of the plastic films through a heating sealing machine for using, the plastic films after the heat sealing are arranged on the leaf and branch part of the michelia albe tree in a sleeved mode, then the opening part of the plastic films is tied tightly through a hemp rope, and a tying part needs to wrap the trunk of the michelia albe tree. The anti-freezing method for the michelia albe tree is mainly used for preventing the michelia albe tree from freezing injuries.

Study on Canopy Characteristic Indices of 7 Magnoliaceae Tree Species

Abstract: Canopy characteristic indices of 7 magnoliaceae tree species in ZhongShan Arboretum were obtained and analyzed by using hemispherical photography technology. Results showed that the LAI of Michelia macclurei, Michelia fulgens and Michelia alba were greater than that of others, indicating that these tree species had stronger capacity of intercepting and utilizing solar radiation. Magnolia wufengensis with greatest canopy openness and least LAI had greatest understory light condition. Results also indicated that the effect of LAI on understory light condition was greater than that of Canopy Openness and that Transmitted Total Solar Radiation was more mainly determined by Transmitted Diffuse Solar Radiation rather than Transmitted Direct Solar Radiation.
