Post-fertilisation: Structures and Events

Question

Why is vivipary an undesirable character for annual crop plants?

Easy

A

It reduces the vigour of the plant
B

It adversely affects the fertility of the plant
C

The seeds exhibit long dormancy
D

The seeds cannot be stored under normal conditions for the next season

Solution

Viviparous plants have poor seed viability. If crop plants have vivipary, the seeds of crop plants can not be stored for longer duration and moreover, the seeds start germinating when they are still in the fruits of parental plant.
