Jan 7, 2024 · A seed lands on the ground, absorbs water, and germinates. It is all so simple – or is it? In this post I will have a closer look at something called seed dormancy. What causes it and how do you overcome it so the seed germinates. Seed dormancy – germinating Fritillaria seed, by Robert Pavlis.

Seed dormancy is a fascinating phenomenon observed in many plant species. It refers to a period of suspended growth and development in seeds, even under favorable conditions. Seed dormancy acts as a survival strategy, ensuring that seeds germinate under optimal conditions for seedling establishment and growth. In this article, we delve into the con...
Seed dormancy is a built-in mechanism that prevents seeds from germinating immediately after dispersal. It is an adaptation that allows seeds to survive adverse environmental conditions, such as unfavorable temperatures, drought, or competition from other plants. Dormant seeds remain viable for extended periods until conditions are favorable for ge...
There are several types of seed dormancy, each with unique characteristics and triggers. The major types of seed dormancy include:
Breaking seed dormancy is essential for successful germination. Gardeners, horticulturists, and researchers employ various methods to overcome seed dormancy, such as:
Seed dormancy plays a crucial role in the survival and dispersal of plant species. Understanding the different types of seed dormancy and the factors influencing it is essential for successful seed propagation. By employing appropriate dormancy-breaking techniques, gardeners and researchers can unlock the potential of dormant seeds and contribute t...
Feb 22, 2023 · Seed germination and dormancy are vital components of seed quality; hence, understanding these processes is essential for a sound seed production system. The two processes are closely interrelated and regulated, both by genetic as well as environmental factors.
Sep 29, 2023 · Seed dormancy is the natural state in which a seed remains inactive and unable to germinate, even under favorable conditions. This mechanism allows seeds to withstand unfavorable environmental conditions until conditions become more suitable for growth.
Jul 14, 2006 · Seed dormancy is an innate seed property that defines the environmental conditions in which the seed is able to germinate. It is determined by genetics with a substantial environmental influence which is mediated, at least in part, by the plant hormones abscisic acid and gibberellins.

4 days ago · Seed dormancy is nature’s way of setting a time clock that allows seeds to initiate germination when conditions are normally favorable for germination and survival of the seedings. For example, dogwoods produce mature seeds in the fall, but conditions are not suitable for seedling survival at that time.
Mar 28, 2014 · In plants, seed dormancy is defined as an innate constraint on germination under conditions that would otherwise promote germination in nondormant seeds (Simpson, 1990 ). Dormancy enables seeds to avoid germination during periods that are only ephemerally favorable.
