Gladiolus is one of the most famous and remarkable flowers among bulb flowers in the world and a favorite fans. Due to its easy cultivation, pretty flower, long spike, color diversity and longevity of cut flower, it is cultivated in large culture areas and sent to market. Various factors, such as climate, soil structure, depth culture, distance of the corm, soil nutrition and size of the corm, have vital function in the growth and development of the flower. The Khuzestan province, despite the limit-entailing factors of clays and heavy soil, is ranked third among the bulb flower production provinces in Iran . Moreover , due to the rapid increase of temperature after harvesting the cut flower in this province, the physiological growth of the corm is not completed. There for the corm, produced the province year, can not be utilized next year. Thus, to minimized the expense and to appropriate use of water and land, it seems necessary to determine the best plant distance. Accordingly, to determine the effect of depth culture of corm and plant distance on culture line and between culture lines on quality and quantity of cut flowers of the Oscar cultivar, an experiment was done in the research field of horticulture section of Ramin Agricultural Research and Education center, Shahid Chamran University in 2003. the long stem of cut flower, the results show that for two factors, long stem of cut flower and the number of stems were not be significant. But for the number of inflorescence and the number of cut flower in each plot were evaluated. The resulted show that for two factors, long stem of cut flower and the number of stems were not be significant. But for the number of inflorescence , the depth of culture and the effect of mutual of depth culture x plant distance were significant in the level of 1% and 5% respectively. It should be mentioned that the depth culture of 15cm was superior to 10cm
