江西典型土壤条件下烟叶类胡萝卜素代谢特征研究
A Study of Characteristics of the Metabolism of Flue-cured Tobacco Carotenoids under Typical Soil Conditions in Jiangxi Province
摘要
Abstract
To research the differences of the metabolism of flue-cured tobacco carotenoids under different soil conditions,the same tobacco variety( Nicotiana tabacum L cv.K326) was planted in typical sandy loam paddy soil and dryland purple soil-two different soil conditions in Fuzhou City of Jiangxi Province.The carote-noid contents and the expression of several key genes related to carotenoid metabolism were analyzed.The re-sults showed that the accumulation of tobacco carotenoids was relatively abundant when planted in dryland pur-ple soil,especially at the late development stages.But,the expression of the key genes related to carotenoids biosynthesis and degradation was relatively higher when planted in the sandy loam paddy soil in Guangchang County which suggested that the carotenoid metabolism was more active under that soil conditions.At the same time ,the analysis of the neutral aroma components showed that the content of the degradation products of carot-enoids were similar under two different soil conditions;while several components such as megastigmatrienone, beta-damascone and geranyl acetone were more under the dryland purple soil condition which might be the main reason why K326 showed different aroma style.关键词
