Meiosis II resulted in a microspore
tetrad from each dyad.
Besides the genotype and the developmental stage of the microspore
, the third critical factor is culture conditions, and in particular the physical and/or chemical treatment necessary to trigger microspore
Three thousand five hundred and fifty meiocytes in prophase I, metaphase I, anaphase I and 1635 tetrads and microspores
Soon, the wall surrounding the 4 microspore
cells dissolve and the microspores
in the pollen sac are released.

In this third type, the cell walls degenerate and the individual protoplasts, without formation of a plasmodium, intmde the locules often in a cyclic pattern during microspore

Exuberant metabolism of the tapetum could provide enzymes, hormones, favorable nutrition for developing PMCs and microspores
, and regulate the proper release of microspore
(Zhao et al.
There was a significant correlation between microspore
mother cell divisions and anther's tapetum development that is coincides with other reports for dicotyledonous plants [7,10,6].
