Abstract
Effects of the structure of the cultivating bed, soil, watering and fertilization on carnation stunting and proliferation syndrome were evaluated by multi-regression analysis (quantification method 1) based on the results obtained from the relationship between the syndrome and items related to soil environment. The syndrome was promoted by poor drainage caused by the structure of the isolation bed with a flat concrete floor and wooden frame and also by the soil structure with a less solid phase and more liquid phase including rich organic amendment. The rapid change in soil moisture and fertilization concentration, for example watering at long intervals and application of dense liquid fertilizer, was also an important factor influencing the syndrome.
