Rooting Patterns in Wheat Cultivars of West Japan

[摘要] Rooting patterns of wheat were investigated using one old and one new cultivars of West Japan, Shinchunaga and Omasekomugi. The wheat plants were grown in small containers and distribution of roots was compared. The numbers of primary roots of main shoot and tillers did not differ between the two cultivars. However, the number of roots at each depth in the soil differed between the two cultivars; the number was larger in Omasekomugi than in Shinchunaga except at shallow depth. This difference became larger with increasing depth. Almost the same result as in the number of roots was obtained also in the fresh weight of roots. The average root lengths of main shoot and tillers were longer in Omasekomugi than in Shinchunaga. This difference may cause the difference in the distribution with depth of roots in the soil.
