【 摘 要 】

The developmental process of leaves and stems of winter type wheat Iwainodaichi in early sowing and its relationships with leaf and stem heteroblasty were analyzed. Iwainodaichi and spring type wheat Chikugoizumi were cultivated by early and standard sowing. For each sowing the leaf length increased successively. The leaf position, at which the leaf length increased rapidly, was higher in Iwainodaichi than in Chikugoizumi in early sowing, but was not different between the cultivars in standard sowing. At the high positions on the main stem the length of leaf blade of early sowing were shorter than those of standard sowing probably due to the suppression of leaf elongation by a low temperature. The flag leaf of Iwainodaichi was smaller than that of Chikugoizumi. The early internode elongation stage of Iwainodaichi was later than that of Chikugoizumi in early sowing but the heading and flowering stage of Iwainodaichi was similar to those of Chikugoizumi. The culm length of early sowing was longer than that of standard sowing in both cultivars since the number of leaves and elongated internodes on the main stem increase as the growth duration becomes longer. Although the two cultivars had a similar culm length, the upper internodes of Iwainodaichi were relatively shorter than those of Chikugoizumi.
