MATTHES, Luiz Antonio Ferraz  and  UNGARO, Maria Regina Gonçalves. Influence of the seed position on the oil percentage and moisture content in the sunflower (Helianthus annuus L.) head. Bragantia [online]. 1983, vol.42, n.1, pp.239-244. ISSN 0006-8705.

In this experiment we tried checked if there was variation in the oil percentage and moisture content in sunflower seed localized in different parts of sunflower (Helianthus annuus L.) head. Twenty heads from 'Record' variety, and ten from 'URL III' variety, both open-pollinated materials, were sampled. Each head was divided into three concentric ring-shaped zones and four samples were taken from each head, i. e., one from the central zone, one from the perimeter, and one from the intermediate zone. A fourth sample was taken from the mixture of the seeds from the hole head. The results obtained with these materials showed that the samples must be taken from the intermediate zone, if the results are to be used for selection of plants of better oil quantity. To analyze the moisture content, the seed sample should be taken from the hole head.
