Answer:
Some annual food plants
such as wheat do not flower, unless they experience a low temperature. They
remain vegetative during spring (warm period) but grow further to bear flowers
and fruits after receiving low temperature (in winter).
The low. temperature
in winter prevents precocious reproductive development in autumn, thus enabling
the plant to reach vegetative maturity before reproductive phase.
Thus, when
spring varieties are planted in spring, they flower and bear fruits prior to end
of growing season. But, if the winter varieties are planted in spring, they
fail to flower and produce mature grains before the end of growing season, as
they could not perceive low temperature of winters.
