• Abstract:

  The family Poaceae (grass)

  presents in the embryo present in its seeds,

  only a cotyledon at the germination, presenting

  hygienic germination. In this family are grasses,

  have linear leaves, naked flowers, and the

  inflorescences are spikes, panicles and

  racemes. The fruit is a karyopus. Theoretical

  and practical activities of plant identification

  occurred during the first semester of 2017 during the oriented teaching discipline of the Postgraduate Program in Family Agricultural

  Production Systems of the School of Agronomy Eliseu Maciel / UFPel, in the discipline

  of Systems of forage production of the upper course of Agronomy classes M1 and

  M2. Twelve forage species and their variations of the Poaceae family were selected,

  six from the cold season and six from the hot season, which were in the vegetative

  period. The plants were conditioned in plastic cups of 500ml capacity with soil, then

  carried to the classroom. At first, theoretical explanation took place with the aid of a

  Power Point presentation of the main characteristics of the plants. Later, the students

  had the time to analyze and verify in detail each structure that differentiates them.

  Main difficulties of the students of the Course of Agronomy FAEM / UFPel, were the

  following: Identification of the leaf structures that differentiate the cold season grasses;

  Identification of characteristics that make it possible to differentiate perennial plants

  from annuals, their habit of growth, the way in which the species is propagated and the

  appropriate defoliation management for each species.
