摘要:
The present invention addresses the problem of providing a plant cell differentiation promoter with which it is possible to promote differentiation from a callus to a normal adventitious embryo, or promote differentiation of an adventitious root or adventitious bud from a plant cutting, and as a result, obtain a regenerated plant with stability. The present invention provides a plant differentiation promoter comprising as the active ingredient a specific ketole fatty acid or derivative thereof.
摘要:
An inducing agent for plant root including a ketol unsaturated fatty acid having 5 to 24 carbon atoms, 1 to 6 double bonds between carbon atoms and an α ketol structure or γ ketol structure (in particular 9-hydroxy-10-oxo-12 (Z),15(Z)-octadecadienoic acid is preferable), which inducing agent for plant root may be used to promote or induce the root growth even when transplanting by cutting plants for which root generation is hard such as pine, cedar, tea, chestnut, may be used even for root growth of cuttings of Prunus x yedoensis (cherry trees) for which root growth is considered impossible, Hypericum chinense for which is transplantation by cutting is said to be difficult, and Paraserianthes falcataria Becker useful as a material for plywood, and may be used by a simple technique such as spraying.
摘要:
The present invention provides an antioxidant and a whitening agent having high safety, and a external preparation for skin using the same. The antioxidant and whitening agent comprise, as an effective component, one or more extracts from Basidiomycetes selected from the group consisting of Pleurotus abalonus, Pholiota squarrosa, Onnia orientalis, Astraeus hygrometricus and Pleurotus nebrodensis. These extracts have a free radical capturing ability and are useful for suppressing skin oxidation and for preventing and improving skin aging. In addition, the extracts have a tyrosinase activity inhibiting action and can suppress the melanin generation. Since the fruit bodies of these Basidiomycetes have been used for edible purpose and have high safety, they can be used preferably for an external preparation for skin.

摘要:
An improved process for the organ cultivation of a Mishima-saiko root is provided. In the cultivation of a Mishima-saiko root, by carrying out the cultivation while regulating the saccharide concentration to be less than 2%, until the adventitious roots have spread out, and optionally adding an additional saccharide, the productivity of saiko-saponin can be enhanced.
