| Abstract: | Systematical observations on internode growth and development of winter,semi winter and spring variety wheat genotypes indicated that before re green sage there were always 4 overlappedly growing young leaves wrapped by the sheath of the leaf whose apex had just gone out of the preceding leaf sheath.As the growing process advances,those 4 nodes from which these 4 overlappedly growing young leaves generate,grow gradually up to internodes.It is these internodes together with the internode just below the ear,that constitute the five internodes on the aboveground wheat plant. |

| Keywords: | wheat number of the aboveground internodes leaf whose apex has just gone out of the preceding leaf sheath mechanism of formation |
