1. Generally speaking, existence or non-existence of a scutellar bundle in mesoctyl of cereals will not accord with the place of the botanical classification strictly, but elongation of mesccotyl possessing a scutellar bundle besides common strand may be not so striking. So there may be some relation between mesocotyl elongation and its structure. 2. Occurrence of highly numbered strand of coleoptile may be regarded as a principle all over cereals, and this may be favorable to a single nature theory of coleoptile. 3. Number of protoxylem of seminal root may be definite with each crop. But number of protoxylem of seminal root of individual having extra strand in coleoptile will not necessarily be larger than having common strand only. So there may be no correlation between coleoptile and seminal root relating to strand number in each variety of every crop.
