In this study, a real-time measurement system was developed to observe living plant stomas continuously for a long period in a growth chamber using a microscope and a color TV camera. Six treatments were conducted by changing the CO2 density, ranging from 100 to 3000ppm, under the conditions of a 2-hour on/off light cycle. From the experimental results, it was observed that the pore size was drastically changed in response to the CO2 conditions. Lower CO2 density caused larger-size pores under conditions of less than 1000ppm CO2 density, while the pore size was almost constant under conditions of greater density. With CO2 density of over 2000ppm, pores continued opening after 60 minutes had elapsed. The transient response with the 1 st-order lag element could well express the stoma response, and its desired value had a high correlation with CO2 density.","PeriodicalId":315038,"journal":{"name":"Shokubutsu Kankyo Kogaku","volume":"49 5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2004-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129267854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, the laser-diode lamp has been proposed as a new type of light source for plant production. The advantages of the laser-diode lamp over conventional light sources are its high electrical-to-optical power conversion efficiency, low thermal radiation, easy set-up for high power and pulse irradiation, small weight and small volume for mounting, and selectivity for proper wavelength. Because laser light itself differs from the light sources presently used in plant growing, we confirmed the possibility of growing plants under the laser-diode light by growing lettuce (Lactuca sativa L.) plants. Lettuce seedlings with 5-6 leaves were grown under a laser-diode lamp panel with 30 pieces of high-power and high-efficiency AlGaInP laser-diodes. The power of each laser-diode lamp was 500 mW, and the wavelength was 680 nm, which was efficient for photosynthesis. The lettuce plants were able to grow under the laser-diode light. However, the weight of the lettuce plants grown under the laser-diode lamps was light, and their leaves were long and thin compared to those of lettuce plants grown under high-pressure sodium lamps.","PeriodicalId":315038,"journal":{"name":"Shokubutsu Kankyo Kogaku","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2000-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131605194","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
