| Abstract: | The study results are as follows:
1) The cytokinesis of the pollen mother cells is of successive type and the tetrads are of symmetrical type.
2) In general, the chromosome number of the pollen mother cells is 2n=36.
3) A mature pallen grain consists of 3 cells.
4) The developing sequence of florets is that florets on the main spikele et develop before those on the branches, the second or third florets develop earlier than the others on branch spikelets and short stalk florets develop before long stalk florets. |
