Advances on regulatory mechanism and index of carbon-nitrogen metabolism in flue-cured tobacco
Journal Title: 广东农业科学 - Year 2018, Vol 45, Issue 12
Abstract
"To study the mechanism of carbon-nitrogen metabolism on the yield and quality formation in fluecured tobacco, and to seek effective measures to improve the quality，this paper summarized regulatory mechanism, the key point of the regulation and the advances on carbon-nitrogen metabolism. It reviewed the effects of coordination in carbon-nitrogen metabolism on quality formation in flue-cured tobacco and advances on its index. Combining the results of the author's research group in the past 15 years, it indicated leaf water content, sap concentration, chlorophyll content and the ratio of (100%-Leaf containing water) / total nitrogen content(namely leaf dry matter content/total nitrogen content) could be the measured indexes for reflecting the intensity and coordination degree of carbon-nitrogen metabolism. Besides, it forecasted that the features on carbon-nitrogen metabolism in high quality tobacco, the indexes of carbon-nitrogen metabolism, the molecular mechanism and regulation pathway of carbonnitrogen metabolism, and the relation between ecological conditions and carbon-nitrogen metabolism could be the focus part in the future."
