Avaliação morfológica de Aveia Branca (Avena sativa L.) IPR 126 sob condições de cortes à dias fixos

Abstract

Brazil is one of the countries with the most favorable climate for the use of pastures for feeding cattle, with an economy that has allowed livestock development without much cost to the rancher. This work will be conducted in Universidade Tecnológica Federal do Paraná, Campus Dois Vizinhos. The experimental design is a randomized block, the present study evaluated the proportion of parenchyma tissue of the inner sheet of White Oats (Avena sativa L.). We used different rest days: 14, 21, 28 and 35, where we had 16 plots. We evaluate this work sheets, made assessment of leaf area ratio of leaf / stem, cumulative average percentage of green matter and mesophyll present in the internal structure of the leaf. he deployment took place on April 24, 2012, was used for planting machinery. Statistical analysis was performed using the GENES also be used a Program Capture and Image Editing, to the photos of the leaf, the average leaf area was calculated by taking the multiplication of leaf length by the width of it, also made average for percentage of accumulated material and mesophyll. We conclude this work we study the anatomical and morphological assessment, is of paramount importance in order to define the proportion of internal tissues of leaves that have higher forage digestibility. This study contributes to the chemical analysis of forage because it is evaluated with the proportion of leaf tissues, so knowing the percentage of tissues more digestible and less digestible in the grass.
