| Abstract: |
| Sixty-nine research papers show that, wheat varieties with longer, thinner, stiffer and faster coleoptile, always give better seedling emergence vigor. Based on years' investigations, from the viewpoints of morphogenesis and cell behavior, the coleoptile internode of wheat is located above the coleoptile, not below the eoleoptile. Both the coleop-tile and the coleoptile interode are produced by the hypocotyl. While the rhizome of corn is below its coleoptile, it is produced by the mesocotyl. Pictures show that the second eoleoptile of the shoot is naturally split, and several leaf intern-odes can occur in deep-sown conditions, and vemalization researchers should attach important to this phenomenon. The genetic length, physiological length and the environmental length of wheat coleoptile are summarized. Breeding wheat for fat quality is mentioned. Three suggestions are proposed for Chinese wheat workers. |
