Development of a plant-factory to produce useful materials of scarcity value.

作为硬纤维的主要来源和某些类固醇的潜在来源，太平洋龙舌兰具有相当重要的经济价值。龙舌兰有三种自然繁殖方式；1)球茎，即发生在花序上的幼芽；2)根状茎，从茎的基部产生的地下茎，在茎的末端出现一个新的植物或分株；3)建立幼苗，这对太平洋龙舌兰来说是极其罕见的，尽管每个花序可以产生几千颗种子。只有很小比例的太平洋龙舌兰是通过幼苗繁殖的。本研究的具体目标是开发一种植物-工厂式的龙舌兰生产系统，从龙舌兰的culcula培养其幼苗，并通过Simulink建立其光合作用模型。该生物反应器系统已成功设计和建造。利用该生物反应器，利用组织培养产生的culculs和种子进行了两种育苗实验。茎尖生长成活率不高，种子成苗生长变异较大。建立了光合作用模型，分析了模型的基本行为。需要进一步的研究来完成模型研究。

As a major source of hard fiber and a potential source of certain steroids, Agave pacifica is of considerable economic importance. Agave pacifica has three natural ways of reproduction ; 1) bulbils which are young plantlets that occur on the inflorescence ; 2) rhizonmes which are underground stems generated from the base of the stems and at the end of which a new plant, or ramet, emerges ; and 3) seedling establishment which is extremely rare for Agave pacifica, even though each inflorescence can produce several thousands of seeds. Only a very small percentage of the Agave pacifica is propagated by seedlings. The specific objectives of the present study are to develop a plant-factory style production system for Agave pacifica, to cultivate its seedlings from cullus, and to develop a photosynthesis model by Simulink.The bioreactor system has been successfully designed and constructed. Two kinds of experiment has been conducted using cullus generated by tissue culture and seeds to grow seedlings using this bioreactor. The survival rate of the growth from cullus was not high and growth variation of seedlings from seeds was relatively large. The photosynthesis model has been developed and the basic model behavior was analyzed. Further study is needed to complete the model study.
