- 摘要:
- 为研究凹头苋各部分物质含量分配比例及动态变化,通过取样处理分析等方法测定凹头苋相关数据,根据根冠比、茎叶比及各器官对全株贡献率等动态变化数据,研究凹头苋的物质分配和物质积累规律。结果表明:随着取样时间的推迟,凹头苋根冠比、茎叶比等各部分比重呈现出相关性。其中各器官的干物质分配在植株的生长过程中表现出规律性变化,并随生长中心的转移和源库关系的变化而变化。
- Abstract:
- In order to study the the matter content distribution ratio and dynamic change of Amaranthus lividus, through the methods of sample processing and analysis determination of Amaranthus lividus?related data, according to the ratio of root to shoot ratio, the ratio of stem to leaf, and each organ of whole plant contribution rate of dynamic change data, distribution and material accumulation of Amaranthus lividus?material was analyzed.The results showed that with the delay time of sampling, Amaranthus lividus?root shoot ratio, stem leaf ratio of each component proportion showed correlation.The dry matter distribution of each organ in the plant growth process showed regular change, and with the growth center of the transfer and the source sink relationship changed.
