Abstract
Institute of Agricultural Sciences, with the objective of finding
an alternative of practical nature, economic and easy execution
that allows soybean conservation during relatively short
periods of time. Different treatments given to soybean seeds
were evaluated in order to extend its conservation period with
high potential of germination. The evaluated treatments
considered seeds from three sowing times, two varieties, three
storing periods (six, nine and 12 months), two types of
containers, two storage conditions (air-conditioning and natural
conditions) and the addition or not of a national product
destined for grain conservation in general. As main criterion
to evaluate the effect of treatments on seed quality after a
storing period (six or nine or 12 months), it was determined by
speed and seed germinability at 48, 72 and 96 hours and root
biomass production at 120 hours. It was possible to establish
the high benefit that represents seed storing in controlledclimate
chambers. Also, it was appreciated that the hermetically
sealed containers were essential in the case that seed was
stored under environmental conditions, which is important to
take into account for a more effective material preservation. Seeds
stored on Dec-January, that is, in summer seeding could be
stored for a year; with regard to the rest of the seasons, it can
not be possible to get to that storing period under the conditions
used.
