Bromus comes from a Greek word for a type of oat, and tectorum comes from tector which means overlaying and tectum which means roof. [2] Bromus tectorum is a winter annual grass native to Eurasia usually germinating in autumn, overwintering as a seedling, then flowering in the spring or early summer. [9]
It has been shown that while some native desert plant species have seeds with self-burial mechanisms that can establish readily in crusted areas, many exotic invasive plants do not. Therefore, the presence of biological soil crusts may slow the establishment of invasive plant species such as cheatgrass (Bromus tectorum). [21]
Bromus is a large genus of grasses, classified in its own tribe Bromeae. [ 2 ] [ 3 ] They are commonly known as bromes , brome grasses , cheat grasses or chess grasses . Estimates in the scientific literature of the number of species have ranged from 100 to 400, but plant taxonomists currently recognize around 160–170 species.
Once a pollen grain settles on a compatible pistil, it may germinate in response to a sugary fluid secreted by the mature stigma. Lipids at the surface of the stigma may also stimulate pollen tube growth for compatible pollen. Plants that are self-sterile often inhibit the pollen grains from their own flowers from growing pollen tubes.
Germination of seedlings raised from seeds of eucalyptus after three days of sowing. In agriculture and gardening, the germination rate describes how many seeds of a particular plant species, variety or seedlot are likely to germinate over a given period. It is a measure of germination time course and is usually expressed as a percentage, e.g ...
Epigeal vs. hypogeal germination. Epigeal germination (Ancient Greek ἐπίγαιος [epígaios] 'above ground', from ἐπί [epí] 'on' and γῆ [gê] 'earth, ground') is a botanical term indicating that the germination of a plant takes place above the ground. An example of a plant with epigeal germination is the common bean (Phaseolus ...

Epigeal vs. hypogeal germination. Hypogeal germination (from Ancient Greek ὑπόγειος [hupógeios] 'below ground', from ὑπό [hupó] 'below' and γῆ [gê] 'earth, ground') is a botanical term indicating that the germination of a plant takes place below the ground. An example of a plant with hypogeal germination is the pea (Pisum ...
