Many plants and seeds recognize this and enter a dormant period in the fall to stop growing. The grain is a popular example in this aspect, where they would die above ground during the winter, so dormancy is favorable to its seedlings but extensive domestication and crossbreeding has removed most dormancy mechanisms that their ancestors had.
True dormancy or inherent (or innate) dormancy is caused by conditions within the seed that prevent germination even if the conditions are favorable. [7] Imposed dormancy is caused by the external conditions that remain unsuitable for germination [8] Seed dormancy can be divided into two major categories based on what part of the seed produces dormancy: exogenous and endogenous.

Why Plants Need Protection. Winter is a rest period for the garden. Many plants go dormant, with their tops dying back and all their energy stored safely below ground. However, not all dormant ...
Annual plants which have seeds that germinate before winter also have winter rest. Winter cereals , for example, which are sown in the fall and germinate before the frost, become dormant during the winter and actually require a few weeks of cold before they are able to flower.
Additionally, many plants go dormant during winter and require less water. Worst Time to Water Indoor Plants. The time of day or season you water indoor plants doesn't matter as much. Generally ...
O’Malia notes that when a plant is stressed, the first thing it wants to do is to flower, since its goal is to reproduce. However, those new buds can cause unnecessary strain on a dormant plant. Tip
Stone fruit trees and certain other plants of temperate climate develop next year's buds in the summer. In the autumn the buds become dormant, and the switch to proper, healthy dormancy is triggered by a certain minimum exposure to chilling temperatures. Lack of such exposure results in delayed and substandard foliation, flowering and fruiting.
Annual plants in deserts may use the weedy ephemeral strategy to survive in the desert environment. These species survive the dry seasons through seed dormancy. Alternatively, some perennial desert plants may die back to their underground parts and become dormant when there is not enough water available. [3]
