Seed vigor is a measure of the quality of seed, and involves the viability of the seed, the germination percentage, germination rate, and the strength of the seedlings produced. [ 47 ] The germination percentage is simply the proportion of seeds that germinate from all seeds subject to the right conditions for growth.
A plant derived from the asexual vegetative reproduction of a parent plant, with both plants having identical genetic compositions. coalescent Having plant parts fused or grown together to form a single unit. cochleariform Concave and spoon-shaped. cochleate Coiled like a snail's shell. coenobium An arranged colony of algae that acts like a ...
A seed plant or spermatophyte (lit. ' seed plant ' ; from Ancient Greek σπέρματος ( spérmatos ) ' seed ' and φυτόν (phytón) ' plant ' ), also known as a phanerogam (taxon Phanerogamae ) or a phaenogam (taxon Phaenogamae ), is any plant that produces seeds .
In seed plants (gymnosperms and flowering plants), the sporophyte forms most of the visible plant, and the gametophyte is very small. Flowering plants reproduce sexually using flowers, which contain male and female parts: these may be within the same ( hermaphrodite ) flower, on different flowers on the same plant , or on different plants .
Botany, also called plant science or phytology, is the branch of natural science and biology studying plants, especially their anatomy, taxonomy, and ecology. [1] A botanist, plant scientist or phytologist is a scientist who specialises in this field.
Seeds typically are embedded in the fleshy interior of the ovary. Examples include: Tomato – in culinary terms, the tomato is regarded as a vegetable, but it is botanically classified as a fruit and a berry. [21] Banana – the fruit has been described as a "leathery berry". [22] In cultivated varieties, the seeds are diminished nearly to non ...
Biological dispersal can be correlated to population density. The range of variations of a species' location determines the expansion range. [6] Biological dispersal may be contrasted with geodispersal, which is the mixing of previously isolated populations (or whole biotas) following the erosion of geographic barriers to dispersal or gene flow.
The seed produces a hollow coleoptile that acts like a 'snorkel', providing the seed with access to oxygen. [4] Temperature affects cellular metabolic and growth rates. Seeds from different species and even seeds from the same plant germinate over a wide range of temperatures.
