From these results, the water use efficiencies of many plants, especially corn were kept at a high level by a high CO2 with a high RH condition. A system developed for growing potatoes, or any plants, in space will have certain requirements that must be met to make them a useful part of a life support system. With comparable yield indices and potential for energy savings, dynamic control strategies will contribute greatly to the sustainability of space-deployed CELSS. Leaf Fe was highest at recommended Skin colour, firmness and EP were measured during shelf life and the incidence of disorders after 7 d. 1-MCP treatment drastically reduced EP, which began to recover after 7 d at 20°C, except for DCA stored pears. The horticulture industry will have to decide whether separate horticultural stations for applied research should remain and what kind of work must be done in the future. Toxicity and deficiency symptoms were more evident with Pn can be manipulated by changing PPF, which is a good environmental parameter for dynamic control of crop production in a Controlled Ecological Life-Support Systems CELSS. The ASTROCULTURE(TM) flight unit is sized to be accommodated in a single middeck locker of the US Space Shuttle, the SPACEHAB module, and with slight modification in the SPACELAB module. Acta Hortic. Control fruit stored in DCA and in CA were greener than NA both at 1 d and 7 d of shelf life. E of rice per plant was lower than those of lettuce and Brassica genera which were reported previously. The machine vision system was capable of determining a plant physiological response to the nutrient stress within 24 hours of the change of the nutrient regime. Acta Horticulturae 174, 49–55. The result of this study showed that the plant growth was affected by microgravity along with other known factors such as vibration and unknown factors. These results showed that the effect of pressure alone was not significant on RGR, but the combination of low pressure with high humidity was important. The effect of vapor pressure deficit (VPD) of air during photoperiod on spinach growth under low total pressure was examined. Solution replenishment occurred when the electrical conductivity (EC) level dropped below 1050. The discrimination rate grew with Stems rapidly terminate in flowers forcing extensive branching and spreading of plants so that individual plants will cover 0.2 m2 or more area. Hourly measurements were continuously made for 16 plants from the first true leaf stage through 30 days from seeding. Composting can be an integral part of a biologically based waste treatment/recycling system. The microclimate, hence the temperature distribution in the greenhouse subscribes this as well. It decreased leaf area ratio (LAR) due to a decrease in specific leaf area (SLA). The rate of loss of dry weight from storage tissue was similar at 17°C and 25°C but slower at 10°C and slower still at 1°C. The more important ones are described. For evaluating water uptake rate under the control of [O2], water flux at the stem base was measured on-line with +/-5% in accuracy, 1 mg s-1 in resolution and 1 min in time constant by heat flux control (HFC) method. The knowledge market used to be dominated by governments, but will be dominated by internationally active private enterprises. Concluding RemarksLiterature Cited. This result shows that the CO2 fixation speed is slower than Fe2+ oxidation speed. However, plants grown using the large nutrient solution container accumulated more storage root dry mass than those with the small containers. The leaf area growths of tomato and eggplant were accelerated by a high CO2, while those of all species were reduced by a low RH. One such experiment that contributed to sweetpotato model development consisted of measuring biomass accumulation of sweetpotato grown in hydroponic culture in a plant growth chamber. Acta Horticulturae (ISSN 0567-7572 print and ISSN 2406-6168 electronic) is a peer reviewed series, mainly the proceedings of ISHS Symposia and the International Horticultural Congress. 72 hours of similar treatments at 60 day after emergence also produced identical results.

Other solid wastes, for example kitchen (food) wastes and human solid wastes, can be composted with inedible plant residues to safely reduce the volume of the wastes and levels of microorganisms potentially pathogenic to humans.

The principle of the measurement is based on the following physiological processes. ; Nelson, P.V. The stomatal lengths of both surfaces increased toward optimum temperature and were longer in the adaxial surface Maintaining this trend, the lengths varied between 16.3 to 23.4 micrometers on the adaxial surface and from 14.2 to 21.5 micrometers on the abaxial surface. We therefore initiated a study of the microbial community inhabiting the root environment, using phospholipid fatty acid (PLFA) profiles, and started to examine whether changes in the microbial population structure would result from the introduction of selected isolates of plant growth-promoting rhizobacteria (PGPR). In this system, an LED is assumed to be a point light source, and only the photons which are emitted directly from LED are considered. A plant growth chamber equipped with a machine vision (MV) system was developed for the continuous, non-contact sampling and near-real-time evaluation of the top projected leaf area (TPLA) of lettuce (Lactuca sativa, cv. Bulb prices decreased, and the domestic production of bulbs decreased sharply, which caused a great reduction in the number of bulb farmers.
