本研究通过１４Ｃ萄葡糖参与珠美海棠（Ｍａｌｕｓｚｕｍｉ）玻璃化发生过程中的代谢活动，测定了玻璃苗不同部位的纤维素和木素中的放射性活度，摸清了玻璃苗中纤维素和木素含量的分布状况及变化。利用中子活化分析技术测定了玻璃苗不同部位中的多种元素含量和分布状况及变化。结果表明，玻璃苗中纤维素和木素的合成速度比正常苗降低了１０３８％，降解速度增加了１８７６％，造成玻璃苗中纤维素和木素含量下降４３６８％；玻璃苗不同部位中绝大多数元素含量低于正常苗的对应部位，其中以茎尖段部位与正常苗对应部位相差最多，仅为正常苗茎尖段中对应元素含量的２５４８％～５８１６％；多数元素在玻璃苗或正常苗不同部位中的分布规律都是相同的，即多数元素均在茎尖段和叶片中含量高，在茎基段和去叶茎中含量低。
In this study, the 14C-glucose involved in the vitrification of Begonia Malpolysia (Maluszumi) vitality during the determination of glass seedlings in different parts of the cellulose and lignin radioactivity, find out the vitality of glass fiber seedlings and Distribution and Changes of Lignin Content. Using neutron activation analysis technique to determine the content and distribution of many elements in different parts of glass seedlings. The results showed that the synthesis rate of cellulose and lignin in glass seedlings was reduced by 1038% and 1876% respectively compared with normal seedlings, resulting in the decrease of cellulose and lignin content in glass seedlings by 4368%. Glass Most of the seedlings in different parts of the content of most elements are lower than the corresponding parts of normal seedlings, of which the tip part of the shoot and the normal parts of the corresponding parts of the most difference, only the normal seedling tip corresponding element content of 25 48% ~ 58 16%. The distribution rules of most elements in different parts of the glass seedlings or normal seedlings are the same, that is, most of the elements are high in stem tip segments and leaves, and low in stem base segments and defoliating stems.
