Cirsium purpuratum is a perennial herb, native to the central Japan. It grows in disturbed habitats. The eruption in 1707, the vegetation has been growing gradually. C. purpuratum has been the dominant species in this area. Around there, some soil disturbance of large scale that is caused by snow slide and mud stream occurs. In addition to this, some soil movements of small scale occurs, too. Under the circumstances it is necessary for species to survive that the seeds germinate, seedlings grow and bear at regular intervals. Therefore I have focused on the process of the seed production to the seedling growth, and have studied what characteristics of C. purpuratum affect to the maintenance of population in disturbed areas.Though the results of this study suggest that in disturbed area, smaller seed size may be advantageous under conditions of limited water availability such as a soil surface. Small seeds may gain a competitive advantage over large seeds due to earlier germination.Thus seed size variation may potentially, affect not only immediate seedling success but also the subsequent maintenance of the population.

紫蓟是一种多年生草本植物，原产于日本中部。它生长在受干扰的栖息地。 1707年喷发，植被逐渐生长。 C. purpuratum 是该地区的优势种。周围存在雪滑、泥流引起的大范围土壤扰动。除此之外，还会发生一些小规模的土壤运动。在这种情况下，物种的生存需要种子发芽、幼苗定期生长和结果。因此，我重点关注了从种子生产到幼苗生长的过程，并研究了紫花紫花的哪些特性会影响受干扰地区种群的维持。尽管本研究结果表明，在受干扰地区，较小的种子尺寸在可用水有限的条件下（例如土壤表面）可能是有利的。由于发芽较早，小种子可能比大种子获得竞争优势。因此，种子大小的变化可能不仅会影响直接的幼苗成功，还会影响随后的种群维持。
