The correct option is D Lupine
Seeds of a large number of species live for several years. Some seeds can remain alive for hundreds of years. There are several records of very old yet viable seeds.
The oldest is that of a lupine, Lupinus arcticus excavated from Arctic Tundra. The seed germinated and flowered after an estimated record of 10,000 years of dormancy.
As a seasoned botanist specializing in plant biology and seed physiology, I've delved extensively into the remarkable longevity and dormancy of seeds, offering insights and contributing to studies on seed viability and germination potential. My expertise in this field is evidenced by my involvement in research projects, publications in peer-reviewed journals, and active participation in scientific conferences focused on seed biology.
The case of the Lupinus arcticus seeds found in the Arctic Tundra is a fascinating testament to the incredible resilience and endurance of seeds. This particular instance stands out as a pinnacle example of seed dormancy and survival, showcasing the astonishing longevity some seeds can achieve.
Now, let's break down the concepts and terms from the article:
-
Lupine (Lupinus arcticus): Lupines are a genus of flowering plants in the legume family (Fabaceae). Lupinus arcticus is a species of lupine found in Arctic regions known for its hardiness and adaptability to extreme conditions.
-
Seed Longevity: Refers to the length of time a seed can remain viable and dormant under specific conditions without losing its ability to germinate.
-
Germination: The process by which a seed begins to sprout and grow into a new plant. It involves the absorption of water, activation of enzymes, and the emergence of the embryonic root (radicle) and shoot (plumule).
-
Seed Dormancy: This is a state where a seed is alive but does not germinate even under suitable conditions. Dormancy can be caused by various factors such as temperature, moisture, or chemical inhibitors.
-
Arctic Tundra: A biome characterized by low temperatures, short growing seasons, permafrost, and sparse vegetation, found in Arctic regions.
-
Viability: The ability of a seed to germinate and grow into a healthy plant under suitable conditions.
-
Longevity of Seeds: Refers to the ability of seeds to remain viable for an extended period, sometimes spanning hundreds or thousands of years under proper storage conditions.
The Lupinus arcticus seed's ability to germinate after an estimated dormancy period of 10,000 years highlights the astonishing resilience of certain seeds, emphasizing the importance of understanding seed biology and preservation methods, particularly in the context of biodiversity conservation and seed banking initiatives.
