Question

Some varieties of wheat are known as spring wheat, while others are called winter wheat. The former variety is sown and planted in spring and is harvested by the end of the same season. However, winter varieties, if planted in spring, fail to flower or produce mature grains within a span of a flowering season.

Answer

Some annual food plants, such as wheat, require exposure to low temperatures in order to flower. These plants typically remain in a vegetative state during the warm spring period and only advance to the flowering and fruiting stages after experiencing the cold temperatures of winter.

The low temperatures during winter serve a crucial role by preventing premature reproductive development in autumn. This regulation allows the plant to achieve vegetative maturity before entering the reproductive phase.

Consequently, when spring wheat varieties are sown in spring, they are able to flower and produce fruit before the end of the growing season. However, if winter wheat varieties are planted in spring, they do not flower or produce mature grains by the end of the growing season. This is because they do not encounter the necessary cold temperatures required for their developmental transition.
