【 摘 要 】

In azuki beans, the initial growth is important for stabilizing the azuki bean production in cool weather regions. In 2003 and 2004 the growth of leaf surface of the primary, first, second and third leaves was investigated in the field using two cultivars, Erimoshouzu and Shumari. Both cultivars were seeded six times at two-week intervals on the same days in both years. Leaf area was the smallest in the primary leaf and increased with ascending leaf position in both cultivars. The same tendency was observed irrespective of seeding date with a few exceptions in both years. The epidermal cells had a bumpy polygon shape. The area of each cell ranged from 191 μm2 to 6088 μm2. The area of each epidermal cell on the primary leaf was larger than that in the other three leaves, and progressively increased with delaying seeding date; this tendency was not observed in the other leaves. The leaf area was highly correlated with leaf length and leaf width for all leaves, but there was no correlation between the leaf area and the area of each epidermal cell, except for the primary leaf. The correlation of leaf area with leaf width was higher than that with leaf length.
