The influence of seed size on sunflower protein content

Abstract

Seed quality is a collection of seed attributes which are considered to be of significance for the value of the seeds used for sowing purposes. Seed size is one of the seed quality components which affect the performance of the crop. A commercial seed lot is rarely uniform in seed size, and seeds of various sizes within a seed lot can have different quality properties. In this research, the influence of seed size on seed protein content was investigated. Sunflower hybrid seeds were classified into two categories by seed size: large (seeds retained on a > 4.5 mm screen) and small (seeds that passed through a 3.5-4.5 mm screen), and then each category was separated in the gravity desk by specific mass.
