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，龙舌兰具有相当大的经济重要性。龙舌兰有三种自然的繁殖方式：1）珠芽，是在花序上出现的幼小植株; 2）根茎，是从茎的基部产生的地下茎，在其末端出现新的植物或分株; 3）幼苗建立，这对于龙舌兰来说是极其罕见的，即使每个花序可以产生数千粒种子。只有很小比例的龙舌兰是通过幼苗繁殖的。本研究的具体目标是建立一个植物工厂式的龙舌兰生产系统，培养其苗从culb培养，并建立了一个光合作用模型的Simulink。生物反应器系统已成功地设计和构建。利用该生物反应器进行了组织培养产生的愈伤组织和种子育苗两种试验。愈伤组织生长的成活率不高，种子成苗的生长变异较大。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.
