Abstract : Seeds of cucumber were cultivated under the influence of daily exposure to incandescent light originated from 100 W, 220 V lamp (normal tungsten filament bulb). The seeds were divided into five categories; 0, 1, 2, 3 and 4 ms far from the lamp. Each category is subdivided into four groups and exposed to the lamp for (1/4, 1/2, 3/4 and 1 hour daily). Seedlings are examined for plant lengths , plumule: radicle ratio, leaf colour, area and numbers, radicle shapes and secondary roots status after 3 weeks of germination, while analyses for fresh , dry weight , photosynthetic pigments and sugar contents carried out after 45 days of plantation. The results revealed that plant length, leaf area, fresh weight and photosynthetic pigments have been significantly affected, while sugar content and dry weight are insignificantly affected by the exposure to the lamp. To show the most optimum distance and time of exposure for each investigated character the results were analyzed using Response Surface Analysis (RSA) and SpineFitting (SF) analysis and an ANN models.
