Qualidade física e fisiológica de sementes de cártamo submetidas ao beneficiamento em mesa de gravidade

Abstract

The use of alternative crops in the off-season becomes interesting in the rotation system this system provides breaking of disease cycles, assisting in the control of weeds and insects. Safflower culture meets these precepts for use in this way in the state of Rio Grande do Sul, as well as assisting on the decompression and translocation of nutrients in the soil, as the root system can reach up to two meters deep. The experiment was constituted by 40 treatments, involving two factors: factor Aeight lots of safflower seed, factor Bfive collection points at the gravity table. Was utilized the delineation in a subdivided plot in factorial scheme (8X5), with four replicates. The seeds were subjected to the following determinations: specific mass, a thousand seeds mass, germination, first germination count, seedling emergence, full seedling length, full dry mass of the seedlings. The objective of this study was to evaluate the physical and physiological quality of seeds of Safflower (Carthamus tinctorius (L)) submitted to processing on the gravity table with different lots. The seeds collected at the upper exit of the desymmetric table presented the best characteristics, as well as the best characteristics observed compared to the seeds that didn´t processing.

Physiological Quality of Processed, Reprocessed, and Stored Sorghum Seeds: Impact of a Densimetric Table

“…Félix et al (2017) stored Adonidia merrillii seeds found that seedling length had a progressive decrease with the advancing storage period, confirming the results of this study. Macedo et al (2020) evaluated the physical and physiological quality of safflower seeds submitted to processing in a densimetric table and identified that the total seedling length may be related to seed density, specific mass, and thousand-seed mass.…”
