Comparison of Brassica Vegetables in terms of Root System Architectures

Authors: Seda Atasoy, G. Tuğba Şahin, Ahmet Balkaya

Abstract: Among winter vegetables, Brassica vegetable crops constitute the most important product segment group. The growth and development of these vegetable species are adversely affected due to abiotic stress factors. For this reason, it is of great importance to determine the root system architectures in plants that can effectively use water and nutrients from the soil. In this study, it was aimed to examine in detail the phenotypic root characteristics (total root length (cm), root surface area (cm2 ), root volume (cm3 ), root diameter (mm), root tip and fork number) that form the root system architecture of kale, white head cabbage, red head cabbage, cauliflower, Brussels sprout and broccoli by using WinRhizo root imaging systems. As a result of the research, at the end of the 45th day from planting, the total root length of the plants varied between 856-1588 cm. The highest total root surface area were measured as 786 cm2 in leaf cabbage and 727 cm2 in broccoli. When all root parameters were evaluated together in the correlation analysis, it was determined that there was a positive and very significant relationship between root length and root surface area. In addition, it was determined that the root length was positively correlated with both root branching and root intersection, and the relationship levels were significant.
