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.

Chemical treatment on dormant plants has been proven to be an effective method to break dormancy, particularly in woody plants such as grapes, berries, apples, peaches, and kiwis. Specifically, hydrogen cyanamide stimulates cell division and growth in dormant plants, causing buds to break when the plant is on the edge of breaking dormancy.
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
Use these tips to care for mums indoors as dormant plants or as houseplants.
Make sure plants enter the dormant season in a healthy and vigorous condition. Proper irrigation during autumn will help prepare landscape plants for the coming winter. Choosing Cold-Tolerant Plants
Many seed species have an embryonic dormancy phase and generally will not sprout until this dormancy is broken. [ 1 ] The term stratification can be traced back to at least 1664 in John Evelyn 's Sylva, or A Discourse of Forest-Trees and the Propagation of Timber , [ 2 ] where seeds were layered (stratified) between layers of moist soil and the ...
They’re just dormant. “Dormant plants are alive,” said Sharon Yiesla, plant knowledge specialist at The Morton Arboretum in Lisle. “They’re just inactive.” Dormancy is a tactical ...
Photoblasticism is a mechanism of seed dormancy. Photoblastic seeds require light in order to germinate. [2] Once germination starts, the stored nutrients that have accumulated during maturation start to be digested which then supports cell expansion and overall growth. [3]
