Anthropic pollen indicators: poaceae pollen of non-native species in Southern Brazil

Abstract: The Poaceae species have their use for food known in Brazil and in the world. Maize, which today accounts for 21% of human nutrition, was changed 9,000 years ago from Teosinte. Many indigenous people grow maize in South America to feed the tribe. In Brazil, several Poaceae species of African origin were introduced accidentally purposely in the colonial period, to be used as fodder, as was the case of annoni grass (Eragrostis plana Nees). Palynological studies may reconstitute a vegetation of the past, but due … Show more

“…Morgado et al (2015) defined pollen grains of Z. mays are large, spherical and ovoid. Radaeski et al (2018) analyzed pollen grains of Z. mays as Spheroidal, monoporate, radially symmetry, monads, pore circular with anulus. We noticed monad and large size pollen grains of Z. mays having PD of 73.65 μm, spheroidal, sub‐prolate grains having P/E ratio (1.15).…”

“…However, insufficient attention is given in the scientific literature to the issue of studying the morphology of grass pollen. Available sources indicate the interest of scientists in studying the structure of pollen in agriculture [22], as well as -the interest in fossil pollen studies [12,23].…”
