【 摘 要 】

To clarify the effect of seed-rhizome weight at planting on the vegetative growth and yield of new-rhizomes in edible canna, seed-rhizomes weighing 20-500g (fresh weight) were planted at 1.0m×0.5m spacing and cultivated in the experimental field of the University of Tsukuba, Ibaraki, Japan. Shoots from the heavier seed-rhizomes required fewer days to emerge from the soil and had more rapid growth and greater yield than shoots from the smaller seed-rhizomes. However, this tendency did not continue for the seed-rhizomes weighing more than 200g. Therefore, it is concluded that the appropriate weight of seed-rhizome for practical cultivation is about 200g.
