为了解蕨麻生长过程中源和库的形成及相互关系，进一步为蕨麻产量的形成和提高提供理论依据，从试验田随机选10株蕨麻，出苗后每15d观测研究源器官的建成；待块根开始膨大后，每15d调查5株蕨麻库器官形成指标，并设计了4个处理采用切断匍匐茎的方法了解同化物的运输情况。结果表明：蕨麻的源器官包括基株叶片和一级、二级匍匐茎及其分株，在源器官的增长中，一级匍匐茎及分株的重量和所占的比重高于66％，是最主要的源器官。蕨麻的库器官是块根，一级匍匐茎各分株形成的块根占块根总数的81．0％，其块根的重量占总重量的85．7％，块根的膨大率也是最高为43．3％；块根一般产生于紧靠基株的第2—3个分株下以及匍匐茎顶端的倒数第1—3个分株下，而位于匍匐茎中部的几个分株通常根不膨大。在二级匍匐茎上，块根一般产生在第1—3个分株下，中部和顶端的分株均不形成块根。说明蕨麻同化物在向库器官运输时，具有就近运输和优先供应生长中心的规律。蕨麻基株是主要的能源提供者，而一级匍匐茎运输能力最强。

英文摘要：

In order to understand the relationship of the source - sink formation during the growth of Juema and provide a theoretical basis for the improvement of yield. We randomly selected 10 strains of Juema from the experimental field, and observed the completion of source organs after mergence every 15 days. After the tuberous root enlargement,we investigated 5 strains of Juema sink organs every 15 days and adopted the method of cutting off the creeping stems to understand the transport of photosynthate. The experiment designed 4 treatments. The results of the experiment showed that the source organs comprised of the basal leaves and the primary and secondary stolons and their bran- ches. The weight and the proportion of the primary stolons were the largest, accounting for over 66%, and were the main source organs. The sink organs of Juema were the tuberous roots. The tu-berous root number formed on the first stolons accounted for 81.0% , and their tuberous root weight accounted for 85.7%. The highest rate root enlargement was 43.3%. Tuberous roots occur under the second and the third ramets which were close to genet or the 1 -3 ramets backward from the top of creeping stems. The ramets growing in the middle of creeping stems can not form the tuberous roots. Furthermore, the tuberous roots generally produce the first to third ramets on the secondary stolons. The photosynthate transporting from source to sink organs follows the rule of the nearest transportation and the priority supply growth center. The genet of Juema is the main energy provider, and the primary stolon of Juema has the strongest transport capacity.
