Seed size and shape

May 13, 2024 | by Bloom Code Studio

Seed size, color, and shape may vary from smaller to large, wrinkled, hairy to smooth. The shape and size of the seed are important for dispersal, survival, and germination.
The world’s smallest seed known are found in orchids that are devoid of reserve nutrient and lives in symbiosis with mycorhizal fungi, carnivorous plant, and parasitic plants. The seed of the double coconut palm is the largest seed known.
In many plants, seeds are uniform in size, and seed size depends upon the genetic factors, e.g., wheat.
In peas, the seed form on the central part of the pod is relatively larger because of the competition for the nutrient between ovules on the placenta.
Seeds of Camelina sativa mimic flax seed size and nature that are grown in a particular region.
The flatness of the seed restricts the germination of tropical mora, but the exception is seen in Panicum turgidum seed which can germinate from the convex side rather than flat.
