以26个枣优良品种为试材,采集白熟、脆熟和完熟期的叶片、吊梗和果实的果皮、果肉4个器官的样品,采用HPLC法测定分析了cAMP和cGMP的含量。结果表明:①不同器官的cAMP和cGMP含量均以果皮中最高,果肉、叶片其次,吊梗中最低;②不同发育时期的cAMP和cGMP含量均以完熟期最高,白熟期最低;③不同品种的cAMP和cGMP含量存在极显著差异,如南京鸭枣的cAMP含量(553.55μg.g-1)约为灌阳长枣(46.65μg.g-1)的12倍,彬县晋枣的cGMP含量(201.15μg.g-1)约为山东梨枣(8.86μg.g-1)的23倍;④相同材料中,cAMP的含量多高于cGMP含量,且在不同器官和发育期间的变化规律相似。
Twenty-six jujube cultivars were used as materials to collect samples of four organs of peel and pulp of white-ripened, crisp-ripened and mature-aged leaves, stems and fruits, and the contents of cAMP and cGMP were analyzed by HPLC. The results showed that: (1) The contents of cAMP and cGMP in different organs were the highest in the pericarp, the lowest in the flesh and leaves and the second in the stems; ② The contents of cAMP and cGMP in different developmental stages were the highest at maturity and the lowest at white maturity; CAMP and cGMP contents of Nanjing were significantly different. For example, cAMP content (553.55μg.g-1) of Nanjing duckweed was about 12 times that of Guanyang longjian (46.65μg.g-1), cGMP content of Jinzao (201.15μg.g-1) was about 23 times of that of Shandong pear (8.86μg.g-1); ④The content of cAMP in the same material was much higher than that of cGMP, and the change law was similar in different organs and development .
