Q. Why is vivipary an undesirable character for annual crop plants ?
A) It reduces the vigour of plant
B) The seeds cannot be stored under normal conditions for the next season
C) The seeds exhibit long dormancy
D) It adversely affects the fertility of the plant
Explanation
[Solution from source] In vivipary, seeds germinate while still on the parent plant without any dormancy, so they cannot be dried and stored for sowing next season. That makes the trait undesirable for annual crops. Vivipary means no dormancy, the opposite of long dormancy. Answer (2).
