Root systems exerted morphological plasticity in response to stresses (water, temperature and anoxia). Fractal analysis was valid for quantification of root morphology. The roots in the humid atmosphere would adapt more readily to high or low temperature than did those in the solution. Those adaptations occurred only through physiological responses in the short-term, and additively morphological responses in the long-term. The effects of flow of nutrient solution were evaluated for its contribution to acceleration of root respiration and nutrient uptake. The root system having both parts in the humid atmosphere and solution was found to be available for stable growth of tomato plants. These observations of root responses to environmental stresses will be valuable for product development and use of soilless culture.}, pages = {57--107}, title = {養液栽培におけるトマト根系の環境応答}, volume = {3}, year = {2004}, yomi = {ナカノ, ユウカ} }
