ABSTRACT: Whether different field treatments such as straight
cut, swathing, or pre-harvest aid application can influence the canola storage
is the critical information for growers. The effect of these different field
treatments on the infection and development of microflora on canola seeds with
9%, 11%, and 14% moisture content at 20°C, 25°C, 30°C
and 35°C was determined. To evaluate the microfloral infection and
development, concentration of CO2 and O2 in 150 g
canola bulks were measured every 3 d. At the beginning and end of the study (66 d), the
seed moisture content, germination, visible mold, invisible fungal infection,
and yellow seed count were measured. The swathed and nature ripened canola had
a slightly higher respiration rate at ≥30°C and ≥ 2 wk than the seeds with
other field treatments. The swathed canola had a marginally lower initial germination
and higher germination at 66 d. The Glyphosate
treated and nature ripened canola seeds had a slightly higher chance of visible model development. However,
all these differences were not significant at α = 0.05 level and different field treatments and storage
conditions did not influence the yellow seed count.
