The root activity and early growth of Zoysia japonica Steud. seedlings that were transplanted on cattle dung pats.

摘要

The root activity of Zoysia japonica Steud. seedlings that were transplanted on dung pats was measured using the alpha -naftil amine acid method. The root activity increased during 0-14 days after transplantation and decreased on day 28; however, the activity recovered after day 56. Further, at the completion of the experiment, the dry weight of the aboveground part of the seedlings, which were transplanted on dung pats, was obviously greater than that of the seedlings that were not transplanted on dung pats. These results show that although the nutrient contained in the dung temporarily depressed the root activity of the seedlings, its use led to an increase in the dry matter of the aboveground part of the seedlings.
