**Second phase:**

This is plateau phase where increase in water uptake leads to increase in respiration of embryo preceding activation and synthesis of enzymes. This increase synthesis of nucleic acids and proteins with release of hormones from the embryo.

### **Third phase.**

This is embryo elongation phase. It's a point where radicle protrusion which is generally accepted to be sufficient for completion of germination is visible. This stage entails increased cell enlargement, cell division hydrolysis of reserve food and utilization of soluble organic substance by developing embryo for the growth of the radicle into root and plumule into shoot.
