ABSTRACT: The aim of this study was to evaluate the effect of
different seed coatings on the physiological potential of perennial soybean cv.
Comum. The following treatments were tested: control (no coating); limestone + polyvinyl acetate (PVA); limestone + sand + PVA; limestone + charcoal
+ PVA; calcium silicate + PVA; calcium silicate + sand + PVA; and
calcium silicate + charcoal + PVA. Seeds were evaluated for water content (WC),
maximum diameter (MAD), minimum diameter (MID), 1000-seed weight (TSW),
germination test, germination speed index (GSI), average germination time
(AGT), emergence, emergence speed index (ESI), average emergence time (AET),
shoot length (SL), root length (RL), dry and fresh matter of shoots (SDM and
SFM), and dry and fresh matter of root (RDM and RFM). Coatings influenced GSI,
AGT, emergence, and ESI, but germination was unaffected. The use of silicate
with or without charcoal led to the same AET as that observed in the uncoated
seeds. Coatings did not affect SFM, SDM, or RFM. Coating with limestone + sand
+ PVA or limestone + charcoal + PVA led to increases in SL, SFM, SDM, RFM, and
RDM.
