Tengcha cultivation in Japan and utilization of this plant


The Ampelopsis grossedentata Hand.-Mazz. W. T. Wang (Tengcha) is a specific plant mainly distributes along the southern part of Changjiang River basin. It possesses a high concentration of flavonoids, ployphenol and polysaccharide, which have functions such as antioxidant, antimicrobial, blood sugar and blood pressure control and so on. These effective components make the plant valuable. To utilize Tengcha, cutting and tissue culture has been conducted, and also some cultivars have been selected. The plant is usually used to produce tea and other health products in China. But relatively, some problems also occur in the Tengcha industry. The most serious one is that the lack of standard throughout the whole industry chain. This research aims to cultivate Tengcha in Japan and to find a much more regular way to utilize this plant and finally establish a industry with uniform products.

In the presentation, I will briefly introduce the growth environment, nutrient value and recent research achievement of Tengcha. Then I will move on to the problems existing in the industry and my research plan in the early stage (mainly focus on cutting cultivation).
