Studies on the impacts of grazing carbon, nitrogen, and phosphorus stoichiometry storage are crucial for better understanding nutrient cycles grasslands ecosystems. Using a controlled experimental platform in meadow steppe ecosystem, effects different stocking rates (0.00, 0.23, 0.34, 0.46, 0.69, 0.92 AU ha?1) contents plant functional groups were explored. The major results were: (1) carbon co...

Abstract The extensive and intensive use of herbicides has resulted in the spread herbicide-resistant weeds many crop production systems; therefore, it is imperative to devise new organic weed control methods. Recently, application spent coffee grounds (SCG) agricultural fields been found inhibit plant growth germination thus considered a potentially effective measure. This study aimed evaluate...

Pollen morphology of 20 species belonging to the 14 genera of the family Gramineae has been investigated using light microscope and scanning microscope. It is a stenopalynous in nature. Pollen grains mostly spheroidal, monoporate rarely diporate, ±circular, pores small operculate, non-operculate, annulate or non-annulate. Tectum areolate to scabrate. On the basis of exine ornamentations 5 disti...
