The purposes of this study are twofolds. First, focusing on seedlings and baby leaf production of 3 leafy vegetables and investigates on optimal environmental conditions for mass production. Second, to compare the cost effectiveness and pay back period of baby leaves and lettuce grown in totally controlled plant factory using only artificial light. (方) Highland Experimental Farm of National Taiwan University has extensive studied on the breeding of Pleione (Pleione formosana Hayata). Recently, four new cultivars ‘Mei Snow’, ‘Mei Moon’, ‘Feng Star’ and ‘Feng Romance’ have been granted with plant breeders’ right. Although the popularity for Pleione is increasing, current production capacity is insufficient to meet the market demand. Therefore, the aims of this project are to determine the in vitro multiplication methodology in sugar-free medium of new Pleione cultivars under various light intensities and CO2 concentrations. During ex vitro acclimatization, effects of light source and intensity were also to be determined. (葉) The production of strawberry is restricted in mid-autumn to late spring in low land of Taiwan. Moreover, the relative warm and humid growing environment makes strawberry much vulnerable to pathogen, and which results in over application of chemicals and food safety issue. Therefore, strawberry is a priority crop to fit into high-efficiency and energy-saving plant factory. The ultimate goal of this project is to build a model procedure for strawberry year round production, including the establishment of runner production system, strawberry culture system and the evaluation of the year round production system in the high-efficiency and energy-saving plant factory. The objective of this year will be focus on building the runner production system. The growth form tissue culture plantlets to runner producing plants and runner formation rate of the plants in the plant factory will be evaluated. The physiological index, yield and fruit quality will also be compared at the same time between the developing system and conventional culture system. (楊) Mass production of A. formosanus is done by aseptic seeding and tissue culture. After deflasking, however, the plants easily infected by stem rot and basal rot diseases. To solve this problem, producing plants in a plant factory has been regarded as the best choice. Furthermore, the plants produced are insecticide- and pesticide-free that are safe to consume. This project is aimed to cultivate A. formosanus under artificial light in plant factory, which provides the optimal environment to prevent disease and to reduce production time. The effect of light quality on A. formosanus growth of will also be investigated. (張) Adlay, which is an annual herb grass,is an important crops in Taiwan. Its yield is very affected by climate, soil and other environmental factors. The operation mode of plant factory can reduce the effect of environmental factors on adlay cultivation. In traditional medicine, adlay kernel is used as drug and food ,and adlay leaves, roots, the shell and testa of adlay seed are for medicinal use. The purpose of this study is to produce adlay leaves by soil-less culture, analize the content of functional components, and develop health ingredients.
