Do small seeds mean small plants?

Do small seeds mean small plants?

A. Many reasons for a disparity between seed size and plant size have been suggested, and many aspects of plant development are thought to be related to seed size. Seed size is often related to relative growth speed; smaller seeds develop more quickly than larger ones.

Does the size of the seed matter?

SIZE DOESN’T MATTER: The first year of data from a Monsanto trial found seed size doesn’t have a major impact on yield – although there may be a minor difference in emergence and stand count.

Does the size of the seed affect the size of the plant?

The size of a seed is known to affect the fitness of the plant growing from it; larger seeds often have the higher fitnesses. Many plant species produce seeds which vary in size due to their position in the inflorescence or fruit.

Does size matter in seed germination?

Seed size is an important indicator of physiological quality, since it may affect seed germination and seedling growth, especially under stress conditions. Under non-stressful environments, the use of large seeds is preferable, resulting in more vigorous seedlings with a greater dry matter accumulation.

Do big seeds mean big plants?

Big seeds often produce seedlings which have a higher growth rate (they grow faster) than seedlings from smaller seeds but this doesn’t necessarily mean that they will go on to produce a bigger plant overall. So larger seeds will have more “food” in them than small seeds.

Will larger or smaller seeds germinate faster?

Small seeds have higher ger- mination percentage and germinate faster when compared to large seeds. Nonetheless, seedlings originated from larger seeds have longer development times, resulting in more vigorous seedlings.

Is there an advantage to large seed size?

Although large seeds might be more attractive and apparent to seed predators, large seed size could enable tolerance of seed predators. If seeds are large enough to sustain damage that would kill smaller seeds yet still produce viable seedlings, investment above the minimum by the maternal plant could be advantageous.

Why are larger seeds better?

What advantage would large size have to a seed?

Which plants have the largest seeds?

Lodoicea maldivica, also known as the double coconut, or coco-de-mer, is renowned for producing the largest and heaviest seeds in the world.

Do large plants grow from large seeds?

Part of this variation is related to plant size; large species tend to produce larger seeds than small species, but at any one plant size there is enormous variation in the size of seeds produced (Thompson & Rabinowitz 1989; Rees 1996; Moles et al. 2004; Grubb et al.

Why seed size is important?

Seed size is an important component in plant fitness. It is thought commonly to be an important focus of selection on the life histories of plants (Janzen, 1977), because the likelihood of dispersal (Howe and Kerckhove, 1980), germination (Putievsky, 1980) and survival (Schaal, 1980) can all depend on seed size.
