Abstract: This experiment studies on three propagation materials of A. albus in field and comparison on physiological indexes and analyses the possibility of using the seeds as reproduction material in fields.The results show that some characters of seed, such as the ratio of breadth and height, petiole diameter, and average tuber weight, are not as good as tuber and rhizome, but swell coefficient, the most important economic index, of seed is the highest among three materials, being 24.52 times, greater than those of rhizome (5.68 times) and tuber (2.84 times). This suggests that seed has high productivity, and can be used as propagative material. From the comparisons on some physiological indexes of three materials after their leaves unfold completely, such conclusions are drawn. The soluble sugar content of seed seedling leaves is the highest, 27.637mg/g. Root activity of seed is 1.45 mg/g?h（FW）, evidently higher than those of tuber and rhizome, showing that activity of seed roots are higher than those of tuber and rhizome. Chlorophyll content of seed is lower than that of tuber, but higher than that of rhizome. Soluble protein content of seed is lowest, only 8.55 %. The results indicate that the seeds are higher plant viability, its expansion has played an important role in the swell coefficient increase.
