The present study was performed to examine the high temperature adaptability with CO<sub>2</sub> treatment for tomato under the condition of greenhouse cultivation during summer season. The plants with the CO<sub>2</sub> concentration of 1000 ppm recorded higher scores in Fm/Fo and Fv/Fm but lower score in Fo than others through the measurement of chlorophyll fluorescence, which implicated that the plants with the CO<sub>2</sub> concentration of 1000 ppm had more adaptability to high temperature than the others. At the condition of the same air temperature as 30℃ and 40℃, the photosynthetic rate was increased with the increase of CO<sub>2</sub> concentration. When in the high air temperature state of 40℃, although the photosynthic rate was low in comparison with 30℃, its value was about 18.5umolm<sup>-2</sup>s<sup>-1</sup> in case of 1000ppm. The higher concentration of CO<sub>2</sub> made the more activated anti-oxidation enzyme (superoxide dismutase and peroxidase) for the both cultivars as 'momotaro' and 'minichal'. The cultivar of 'minichal' performed the high temperature limit as 41℃ at the CO<sub>2</sub> condition of 500 ppm and 43℃ at the CO<sub>2</sub> condition of 1000 ppm through the estimation on the variation of chlorophyll fluorescence Fo by CO<sub>2</sub> concentrations.

Shading with silver-coated strips in combination with water spraying over the roof was more effective than others in lowering air-temperatures while the soil temperatures were more efficiently lowered by the silver-coated PE film in combination with water-flowing treatment on the soil surface. Significantly better growth and higher yield of spinach were recorded in the plots having lower soil termperatures. Whitewash spray with lime mixture resulted in higher yield of spinach as compared to the white water-soluble painting, possibly because of the better light penetration toward the end of the growing season by the natural weather off phenomenon.

Use of mobile shading helps ameliorate heat stress of cucumber in greenhouse during summer. The mobile shading according to solar radiation may be optimal to produce high-quality cucumber in greenhouse during summer. Simultaneous comparison was made among greenhouse sections that were either not shaded or covered with reflective aluminized shadecloth that shaded 40%, or 90% of direct sunlight. Solar radiation amount, soil temperature, difference in leaf temperature and air temperature, and air temperature were lower, and relative humidity was higher as shade level increased. With increased shade level, photosynthesis rate, leaf area, fresh weight, dry weight, and number of marketable fruits increased. The mobile shading of 90% when the outer sunlight was above 650W·m<sup>-2</sup> yielded favorable growth environment in greenhouse of cucumber during summer.

Foliar fertilization of carbonated water during lettuce hydroponic cultivation was increased photosynthetic rate and stomatal conductance as higher carbon dioxide concentration of carbonated water The higher the carbon dioxide concentration in the carbonated water was better growth of lettuce. However, the carbon dioxide concentration of 500 ppm and 700 ppm in the carbonated water was increased the tip-burn occurrence, and the yield was higher in the 300 ppm. the carbon dioxide concentration of 300 ppm in the carbonated water was lower in the fresh weight but increased yield resulted in the lower of the tip-burn occurrence The high temperature limits for growth were 32℃ in the control, 33℃ in the 300ppm and 34℃ in the 500 ppm according to analyze chlorophyll fluorescent Fo. The high temperature tolerance in lettuce increased approximately 4℃ by foliar fertilization treatments of carbonated water under this experiment conditions. Also the activity of SOD(superoxide dismutase), the antioxidant enzyme, was higher with high carbon dioxide concentration of the carbonated water.

Fruit quality is essential for increasing marketability and consumer acceptance. To suggest an easy method for measurement of squash fruit quality, 10 varieties/cultivars and 1 populations were used as experimental materials. The fruits were harvested in marketable maturity to investigate the relation between quality factors and sensory test. The total solids content is one of the most important factors associated with sensory taste in fruits. The major squash varieties/cultivars such as 'Puthobag', 'Seoulmadi', 'Aehobag 1', 'Aehobag 2', 'Ford Zucchini', and 'Zucchini' showed total solids content of 6.4, 7.5, 7.3, 5.8, 4.7, and 4.30%, respectively. The preference values for 'Puthobag', 'Seoulmadi', 'Aehobag 1', and 'Aehobag 2', which are generally preferable varieties/cultivars, were 4.6, 4.7, 4.8, and 4.3, respectively. On the other hand, the preference values for variety 'Ford Zucchini' and cultivar 'Zucchni', which are not generally preferable, were 1.6 and 1.4, respectively. There was no significant correlation between plant length and total solids content or starch content in the fruits thereby suggesting the possibility of breeding bush type squash cultivars with good taste. This easy method of weighing dry matters of squash fruits might be useful for marketable quality index.
