The three different methods of emasculation are:
Forcep or Scissor method:
-
The bud of the flower is opened carefully and the anthers are removed from their base using a pair of finely pointed forceps or scissor.
-
This method can be used in case of large flowers. E.g. Tomato, Cotton, Brinjal
Hot or cold water method:
-
This method is used in plants with small flowers in which manual removal of flowers is tedious.
-
Emasculation is done by dipping the inflorescence in hot water (45oC to 53oC) for 1 to 10 minutes. Cold water or alcohol can also be used for the same.
-
This method is used in case of Jowar, Bajra and Rice.
Suction pressure method:
-
Emasculation may also be achieved using suction pressure techniques.
