TL;DR: In this article, a method for breeding michelia variety Yunrui was described, which comprises the following steps of: hybridizing the filial generation and the male generation.
Abstract: The invention discloses a method for breeding michelia variety Yunrui. The method comprises the following steps of: hybridizing michelia yunnanensis serving as a female parent and michelia doltsopa serving as a male parent to obtain a filial generation; and after the filial generation flowers, hybridizing the filial generation serving as a female parent and michelia maudiae serving as a male parent to obtain the michelia variety Yunrui. The new variety 'Yunrui' integrates partial excellent traits of three parents: the shrub is branched, dense and glabrous throughout. The leaves are leathery and oblong to inversely oval long circle, the length is 16 to 18 centimeters, the width is 6 to 8 centimeters, the tip is acute, and the base is narrow and wedge-shaped; the leaves are deep green and glossy; and the petiole nearly has no stipule scars. The flowers are milky white and fragrant; the number of tepals is 9 to 10, the tepals are inversely oval, the length is 6 to 7 centimeters, the width is 3 to 4 centimeters, the base is light yellow, and the tip is short and small; the carpel is green, the style is purple red, the androeceum is light yellow, and the stamen of the base is petalled; and the flowers are expanded and broadly campanulate.

TL;DR: It is indicated that Manglietia should be an independent genus from Magnolia and that the two groups should not be merged as a genus, and cytological evidence is generally less informative in clarifying the intergeneric relationships of the Magnoliaceae than the interspecific relationships within a given genus of the family.
Abstract: In this paper, 40 species in 11 genera of the Magnoliaceae from China were karyomorphologically investigated for a better understanding of the intergeneric relationships in the family and the systematic positions of some species, particularly those in the genus Manglietia. The 20 Manglietia species studied are all diploid with 2n=38, indicating that in this genus the speciation may have taken place predominantly at the diploid level and that minor structural changes of chromosomes may have resulted in distinct morphological divergence. In the genus Magnolia, cytotypes with various ploidy levels from 2x to 6x have been found, which may be, at least to some degree, associated with the wide distributional range and complex gross-morphological variation of the genus. Our results indicate that Manglietia should be an independent genus from Magnolia and do not support the treatment of merging them as a genus. All the Michelia species already with chromosome numbers are diploid with 2n=38, while most of the species in Magnolia subgen. Yulania are polyploid, suggesting that Michelia is not closely allied with Yulania and that the two groups should not be merged as a genus. All Parakmeria members are polyploid. It is noteworthy that cytological evidence is generally less informative in clarifying the intergeneric relationships of the Magnoliaceae than the interspecific relationships within a given genus of the family because reticulate evolution may have extensively occurred in this family. Systematic positions of some species in Manglietia are discussed based on evidence from cytology, morphology and geographical distribution.

TL;DR: Five sesquiterpenoids and one phenolic glycoside have been isolated from the dried branches of Michelia lacei and their structures were elucidated as alloaromadendrane 4α,10β diol, diol-like structures and chemotaxonomic values are discussed briefly in this paper.
Abstract: Five sesquiterpenoids and one phenolic glycoside have been isolated from the dried branches of Michelia lacei and their structures were elucidated as(+) alloaromadendrane 4α,10β diol (1),D aromadendrane 4β,10α diol (2),spathulenol (3), parthenolide (4),11,13 dehydrolanuginolide (5) and syringin (6) by spectral means respectively Compounds 1 3 were aromadendrane and alloaromadendrane type sesquiterpenoids which were first isolated from the genus of Michelia Their chemotaxonomic values are also discussed briefly in this paper

TL;DR: The volatile components of the leaf oil of Michelia balansae (A.DC.) Dandy from the Nghean province, Vietnam were analyzed by Capillary GC, GC/MS as well as by background substraction of coeluting compounds.
Abstract: The genus Michelia comprises over 50 species and is distributed in tropical areas and both hemisphere. The volatile components of the leaf oil of Michelia balansae (A.DC.) Dandy from the Nghean province, Vietnam were analyzed by Capillary GC, GC/MS as well as by background substraction of coeluting compounds. The major components in the leaf oil were α-pinene (18.41%), (α and β-phellandrene (17.36% and 7.42%), germacrene D (17.98%) and bicyclogermacrene (7.55%). The lesser amounts were β-myrcene (3.88%),δ-elemene (5.11%) and β-caryophyllene (3.47%).
