ABSTRACT: Soybean is the most produced oil crop in the world,
with great increase in its annual production as well as great generation of
waste from its industrialization. The soybean hulls can be used for the
elaboration of products such as carboxymethyl cellulose (CMC), adding high
value to this residue and it can be used as a coating polymer in seeds. The
objective of this work was to analyze the physiological quality of soybean
seeds treated with CMC and fungicide, recording images to verify the
effectiveness of the coating in the seeds. The experiment was randomized into
factorial scheme 2 × 4 with four replicates, two soybean cultivars M-7110 and
M-7739 and four types of coating: without (control), CMC, fungicide and
fungicide/CMC. The variables analyzed were: vigor (first count), germination test,
accelerated aging, length and dry mass of the radicle and hypocotyl length. The
images were made with a scanning electron microscope (SEM) with zoom of 50 and
200 times. The CMC used alone or with fungicide, provided good physiological
quality of soybean seeds. In some analyzes there was difference between the
cultivars M 7110 and M 7739. The combination of CMC and fungicide provided a
better coating on the seeds.
