  • chelation

  • stratification

Stratification involves the treatment of seed at low temperature left parenthesis 5 minus 10 degree straight C right parenthesis under sufficiently moist conditions to break its dormancy and to induce germination.
Scarification involves any damage or breakage of seed coat by physical methods (e.g., Use of scalpel, wooden hammer etc.) or chemical methods (use of mild acids) to break seed dormoney.
