| 英文摘要: |
| [Objective] To summarize the research progress on the involvement of potassium participation in carbon assimilate metabolism in plants such as Fritillaria thunbergii Miq.[Methods] According to consultation of the literatures from January 2012 to December 2019 in China national knowledge infrastructure(CNKI)， Web of Science， Pubmed， Wanfang， VIP with the Keywords of patassium， Fritillaria thunbergii Miq and carbon assimilation metabolism， the overview on studies of the physiological mechanism of the response of carbo metabolism to plant potassium concentration was summarized.[Results] A total of 29 related literatures were included， and it was found that photosynthesis was a key factor affecting yield， and carbon assimilation metabolism varied among different plants. Potassium deficiency resulted in decreased leaf area， reduced carbon dioxide conversion， and reduced stomatal conductance. Appropriate potassium application can improve photosynthetic performance， and increase chlorophyll content， sugar content such as sucrose， starch， and related carbon metabolism. Related enzyme activity and key enzyme gene expression will also change accordingly， such as ribulose-1， 5-bisphosphate carboxylase(Rubisco)， carboxylase， fructose-1，6-bisphosphatase(FBPase)， amylase， and the key enzymes in metabolism of sucrose phosphate synthase， sucrose synthetase were all increased. With the gradual increase of potassium application， the trend was first upward and then downward， while the acid invertase activity decreased after potassium application.[Conclusion] The feedback inhibition of leaf photosynthetic capacity is the main reason for the reduction of plant biomass accumulation. Potassium can promote photosynthetic effect by affecting leaf carbon assimilation metabolism and thus increase the yield of Fritillaria thunbergii Miq. |
