Recently Korea has severe drought during sowing and early vegetative period of sesame cultivation. Sesame is an important oilseed crop in Korea, so it is important to understand adaptation of sesame to water stress. This study investigated changes of morphological properties and spatial distribution of sesame roots under different soil moisture contents. The experiment was performed at University of Florida in Gainsville, USA. Two sesame cultivars (Bene and Indie) were planted in a test tube with 35 in length, 21 in width, and 4 cm in depth and grew for 23 days. The tubes were filled with turface soil with four soil moisture treatments (40, 50, 75 and 100%). The root images were obtained every 2 days using a scanner. Root properties from the images were characterized by root length, surface area, volume, number of roots and fractal parameters (fractal dimension and lacunarity). The results of this study showed that the all of root properties had no significant difference between cultures, but there was difference across soil moisture contents. The total length, surface area, volumes and number of roots increased as soil moisture increased from both cultivars. The values of fractal dimension increased as soil moisture increased, while the ones of lacunarity decreased. These results indicated that greater soil moisture induced more abundant and heterogeneous root structure. Correlation analysis among morphological properties and fractal parameters resulted in that the fractal dimension had the greatest correlation with number of roots. This result indicates that fractal dimension is strongly related to branching of roots. Sesame roots from soil moisture of 40 and 50% did not develop enough to have fractal root structure. Sesame roots are sensitive to soil moisture content in germination and early vegetative stage and they require soil moisture close to 100% to develop full root structure. These results would be useful to understand sesame responses to water stress and to manage irrigation amounts in sesame cultivation.

Sesame (Bene and Indie) root images from four soil moisture treatments: a-40%, b-50%, c-75% and d-100% soil moisture content.
