Sentence examples for grass seedlings from inspiring English sources

The hormonal characteristics of IAA are readily demonstrated in grass seedlings, in which the hormone is synthesized at the tip of the coleoptile (the protective sheath of the emerging plumule, or embryonic bud) and passes downward to its point of action in the growing region, where it evokes elongation of the coleoptile cells; growth stops if the tip is removed.

New grass seedlings can establish themselves only after a hurricane or other major disturbance clears a swath of heavily vegetated beach.

Similarly, the number of annual and perennial grass seedlings emerged from the soil seed banks were not affected (P > 0.05) by the canopy cover of tree species, whereas the inside canopy had a higher number of seeds of annual forbs and woody species emerged from the soil seed banks.

Broom seedlings that do germinate (along with desirable grass seedlings during establishment of ground cover) can be killed within the first year using this herbicide mixture, and residual activity will prevent further broom establishment for about 100 days, by which time grass ground cover should be growing strongly.

In a dark room, the artists project a negative image of a photograph onto a wall-mounted sheet of grass seedlings embedded in clay, and allow photosynthesis to finish off the job.

Do rhizobacteria facilitate organic N acquisition by grass seedlings?

The high rate of water losses via overland-flow may limit the possibilities for grass seedling emergence and establishment and favor the persistent dominance of shrubs.

This medium contained no added nutrient source and at 0.7 % agarose concentration was an ideal consistency for grass seedling root penetration.

In a previous study we observed degradation of some of the bacteria on surfaces of grass seedling roots (White et al. 2012).

The developmental dependence of grass seedling roots on the rhizobacteria suggests that grasses have evolved to rely on these seed-vectored rhizobacteria in order to maximize scavenging of organic N. Features of development of grasses seem consistent with this idea.

Through its high seed production and soil water exploitation, B. tectorum can drastically reduce resources for native grass seedling establishment (Melgoza et al. 1990), creating highly competitive conditions where small size may be advantageous.
