According to the analysis conducted by the Tea Research Institute, Chinese Academy of Agricultural Sciences, the contents of caffeine in the one bud and two leaves shoots in spring season averaged 4.16%, amino acids 4.21%, tea polyphenol 21.37%, total catechins 122.62mg/g. The oolong tea prepared with the GSCTn variety as the raw material is characterized by its tight and rolled leaf, bloom color, fragrant and lasting aroma, full taste and golden yellow liquor. The green tea prepared with the GSCTn variety as the raw material showed superb quality.
Suitable to popularize in the tea region in the south-of-Yangzte River for the manufacture of oolong tea.
With well developed rooting system and high tolerance to the fertilizer. It is recommended to increase the applied amounts of fertilizer, go as to fasten the establishment of tea garden and increase the yield. Owing to the ununiform sprouting of new shoots and the week tenderness-keeping ability, it is necessary to pluck in time and in turn.
