Tea(Camellia sinensis[L.]O.Kuntze.)is an important cash crop,which mainly uses tender shoots and young leaves for manufacturing.Due to the marketing characteristic that earlier made tea has higher price,the time of the breaking of winter dormancy buds in spring is extremely important in tea industry.Strigolactones are a group of carotenoids-derived metabolites which regulates bud outgrowth,shoot branching,tiller angle and environmental stress responses.The role of strigolactones in tea plant was briefly summarized in the current review,with an emphasis of the association of strigolactones on bud ecodormancy and shoot branching.The involvement of strigolactones on the biosynthesis of the tea characteristic metabolites flavonoids,caffeine and theanine were also discussed.Moreover,recent advances on the biosynthesis of strigolactones and its regulation by microRNAs and environmental stresses were also presented.This review provides a basis for future investigations underlying the mechanisms of strigolactones on bud winter dormancy and tea secondary metabolism. 展开更多

In order to probe the death reason of terminal buds and carry out trunk extension by using lateralbuds, the temperature characteristics of dormancy development of terminal and lateral buds in Paulowniatomentosa p. fortunei 33 were investigated by raising cutting branches on different date at 25 ℃ and 15 ℃.The results were as follows: ①The death reason of terminal buds and the first pair of lateral buds was itselfecological adapting strategy, not the injury of early frost and freezing; ②The lateral buds 2, 3 and 4 hadobtained the feature of winter dormancy, and could survive from cold winter, and widen its possible temperaturerange of sprouting to lower temperature by experiencing winter chilling; ③The lateral buds 2, 3 and 4 couldsprout at the same time in spring, but it was difficult to sprout for other lateral buds; ④The sprouting ofupper lateral buds could restrict the sprouting of lower lateral buds at 25 ℃, but not at 15 ℃. 展开更多
