DEVELOPING SEED SOURCES OF FLORIDA NATIVE UPLAND GRASS SPECIES

evaluation of practical usability in two iranian native grass species

nowadays, establishment and maintenance of turfgrasses due to high water requirements was faced with serious doubts. hence, screening of drought resistance native grasses, and introduces them as turfgrass is not only effective in reduction of water usage but can also preserve plant gene pools of the country. in the present experiment, wheat grass and bromus as two native grasses were compared w...

A STUDY ON SEED DORMANCY AND GERMINATION IN TEN SPECIES OF GRASS WEEDS

       Seed dormancy has an important role in resistance and survival mechanisms of plants. Finding of some information about the range of primary dormancy and effective factors in dormancy breaking and optimal conditions of seed germination are necessary for weed control and other research purposes.  In this research, the seeds of 10 species of grass weeds in Tehran province fields (Echinocloa...

The Seed Semipermeable Layer and Its Relation to Seed Quality Assessment in Four Grass Species

The existence of a semipermeable layer in grass seeds has been extensively reported, yet knowledge of its influence on tests for seed viability and vigor that depend upon measurement of electrical conductivity (EC) is limited. This study determined the presence and location of the semipermeable layer, and its relation to seed viability and vigor assessment, in seeds of four important grass spec...

Native Deer mice (Peromyscus maniculatus) use of invasive grass seed (Ehrharta calycina) in Coastal California

Productivity and Subordinate Species Response to Dominant Grass Species and Seed Source during Restoration

Grasses can be important regulators of species diversity and ecosystem processes in prairie systems. Although C4 grasses are usually assumed to be ecologically similar because they are in the same functional group, there may be important differences among species or between seed sources that could impact restorations. I tested whether C4 grass species identity, seed source, or grass species ric...
