1. The number of tillers synchronously developed from one root becomes less than the theoretical number, after the growth of [5] of the first tillering rank, and the cumulative tillers' number diverges from the theoretical value, showing a curve represented by the equation; S=an^2+bn+c and S=an+b. (fig. 1) 2. It is caused by decrease of the growing rate, delay of emergence of tillers and increase of tillering ranks' number. 3. In the system of tillering, the stems show the following appearance of death: original stem and its early neighbourings are perfectly died and tillers outside of that are dead in half, then top die, and the most outside stems are normal. As to the length of stems, the original and neighbouring ones and the most outside stems are shortest; and stems inside of that are intermediate dividing two ways, and about the center of that system, there are longest ones. (fig. 2) 4. We can observe the distinct quality of synchronized tillers in appearance of death and length.
