Resumo
The Safflower (Cartamos tinctorius L.), can be an alternative source for renewable
energy production that generates less impact to the environment as well as being a
culture that can be used in human and animal food. There are few studies in the
literature brasilian, about the potential of this culture. This study aimed to evaluate
different conditions of harvest, treatment and storage of safflower seeds as to the
physical, physiological and sanitary attributes. The experiment was conduted in Soil and
Crop Production and bromatology Laboratories of the Federal University of Mato
Grosso, Campus Rondonópolis. The Safflower seeds used were haversted in July 2014
in Primavera do Leste- MT. The experimental design was completely randomized
design (CRD) were performed, with five replications in factorial scheme 5x2
(temperatures and packaging), 2x2 (crop rotations and cultivars) and 5x5 (doses of
fungicide and storage period). The following tests were performed for evaluation of the
physical attributes of the seeds: water content in the seed, weight of a thousand seeds
and hectoliter weight. To evaluate the physiological attributes were performed
germination, tetrazolium, accelerated aging, seedling length and electrical conductivity
of the seed. To evaluate the sanitary attribute was performed "Blotter" test. Analysis of
variance were made using F test and the averages were compared using Tukey test at
5% probability. The paper packaging, at the temperature of 20° C, provided greater
conservation of the seed. The rotation of 692 rpm resulted in higher mechanical damage
to the seeds.
