Amur maple is treated either as a subspecies of Acer tataricum (Tatar maple), [3] or as a distinct species in its own right, Acer ginnala. [2] [4] [5] The glossy, deeply lobed leaves of subsp. ginnala distinguish it from subsp. tataricum, which has matt, unlobed or only shallowly lobed leaves; it is separated from subsp. tataricum by a roughly 3,000 km range gap across central Asia.
It is a measure of germination time course and is usually expressed as a percentage, e.g., an 85% germination rate indicates that about 85 out of 100 seeds will probably germinate under proper conditions over the germination period given. Seed germination rate is determined by the seed genetic composition, morphological features and ...

Over time, seeds lose viability, which is the ability to initiate metabolic activity, cellular growth, and germination. Seeds have many cells and tissues that die over time, [1] and these deaths can be delayed or increased by environmental conditions the seed experiences. Very generally, small seeds, especially from weedy species and annuals ...
