Purple bud Pu 'er tea was a tribute in ancient times. Collected from the wild tea plant community at an altitude of 2480 meters, the age of tea trees is between 500- 1400 years. Tea varieties are different and the quantity is small. Before spring comes every year, it will be refined by traditional crafts once. Its soup is bright in color and full of honey, which is a godsend for health care and improving vitality.
The first academic circles paid attention to the variation of purple buds in Wuyishan. Although it is known that purple bud is a widely distributed variation phenomenon in different plants, it is more common in summer tea. Because of its high anthocyanin content, purple color and bitter taste, it has always been considered unsuitable for making tea. However, in the late 1970s and early 1980s, Wuyi rock tea community found that the purple bud variety of rock tea could produce excellent varieties with high yield and strong stress resistance after cultivation and domestication, and the improved purple bud taste could be less bitter, so Fujian Tea Research Institute selected a new clone variety: purple bud rock tea from the offspring of natural hybridization of Dahongpao. Description: Shrub type, mesophyll type and late bud type. The tender shoots are dark yellow-green, the buds are purple, the petiole base is purple, the internodes are short, the hairs are few, the leaves are soft, the tenderness is strong, the bud tip density is high, the yield is high, the adaptability is wide, and the stress resistance is strong. The germination period of spring buds is generally in the middle and late March, and the period of one bud and three leaves is in the middle and late April. Oolong tea has excellent quality and stable processing quality. The breeding of this variety is a successful example of utilizing and transforming rare tea variety resources, which is suitable for popularizing and planting in oolong tea area.
1985, a tea tree with purple buds, leaves and stems was discovered by the scientific and technical personnel of Yunnan Tea Research Institute in more than 600,000 tea gardens with Yunnan big leaves. Roasted green tea processed from its fresh leaves is purple in dry tea and purple in soup color, with pure aroma and rich taste. Because the buds, leaves and stems of tea trees are purple, and the dried green tea and tea soup are all purple, it is specially named "Zijuan". After research and cultivation, this mutant gave birth to the present tea tree. Traditional purple buds refer to the variation buds of ancient trees with large leaves due to seasons, places of origin and other reasons. There are few trees with purple buds in a tea forest, and there are not many people with purple buds on an ancient tree. But the nightingale is a tea tree cut in the tea garden, with high yield and dense planting. Pre-selected varieties of tea garden were cut, and the light and temperature were increased to make the whole tea garden plant purple from bud to leaf to stem. The leaves of traditional purple buds are dark green and the veins are similar to those of cultivated wild tea. Purple Juan has thin leaves and inconspicuous veins. The traditional Qiaomu Ziya soup has golden color, strong taste and full taste. Zijuan tea (Yunnan green) soup, thin water, brown-green, bitter, indigo leaves. The possible * * * of the two is the high anthocyanin content, which has certain health care value.
199 1 year, Lin yongyue, a senior engineer of Yunnan medical research institute, and others conducted many antihypertensive experiments with domestic cats weighing 2.5-3.5 kg. The results showed that the blood pressure of Zijuan green tea was 35.53%, which was better than that of Yunnan Daye green tea (29.04%). At present, Yunnan Tea Research Institute, on the basis of developing Zijuan antihypertensive health tea, is increasing the propagation of Zijuan tea varieties, hoping to develop and utilize it in weight loss and blood sugar reduction.
Zijuan is an improved variety with strong aroma, but slightly light taste and obvious bitterness. There is a gap with the original purple bud, but many people mistake it for purple bud. Theaceae is a plant prone to genetic variation. As long as it pollinates seedlings, it is usually easy to mutate. In general tea gardens, in order to stabilize the quality and yield, asexual reproduction is usually adopted. If there is variation due to pollination, farmers will pull it out. Among the original varieties of the population, there is a kind of purple bud head, which is usually purple in the third-grade leaves, and then the adult leaves return to dark green, which is called "purple bud" by local farmers in Menghai area.
