Abstract
Container-grown cut rose 'Black Beauty' was irrigated 100 mL every three days with complete nutrient solutions containing nitrogen at 10,40,80,140,200,300 mg perliter and its growth and cut flower quality was investigated in this paper.Better quality was consistently observed when roses plants receiving 80~140 mg perliter nitrogen.Quadratic relationship between the cut flower quality and nitrogen fertilizer rates was also observed and this relationship as mathematical models was applied on quantitative fertilization and quality predictions for rose.The effects of nitrogen nutrient on the cut flowers quality were comprehensively evaluated by fuzzy mathematics through their formation.
