Why is vivipary an undesirable character for annual crop plants?

1. It reduces the vigour of the plant.
2. It adversely affects the fertility of the plant.
3. The seeds exhibit long dormancy.
4. The seeds cannot be stored under normal conditions for the next season.

Correct answer: The seeds cannot be stored under normal conditions for the next season.

Solution

Vivipary means seeds germinate while still attached to the parent plant or soon after harvest. For annual crops, this is undesirable because such seeds lose dormancy and cannot be safely stored for the next sowing season.
