in recent years application of plant growth regulators especially growth retardants, has been significantly increased. trizols (paclobutrzol and trinexapac-ethyl) as the most effective and least harmful growth retardants, induce more dwarf and denser cover plants with both darker and thicker leaves.  therefore, an experiment based on completely randomized block design with 16 treatments and 3 r...

bermudagrass [cynodon dactylon (l.) pers.] is a perennial grass and has been long used as a medicinal herb in iranian traditional medicine to treat varied ailments. different parts of bermudagrass such as leaves, stolons, rhizomes and culms are rich sources of metabolites such as proteins, carbohydrates, mineral constituents, β-sitosterol, flavonoids, alkaloids, glycosides and triterpenoides. g...

Hybrid bermudagrasses occasionally suffer significant damage when below-normal winter conditions occur. In an attempt to enhance cold tolerance of these grasses, a study was undertaken to assess the effects of late-season nitrogen (N) fertilization and applications of the growth regulator trinexapac-ethyl (Primo) on morphology and cold tolerance of ‘Tifton 419’ hybrid bermudagrass. Nitrogen app...
