PHYSICAL PROPERTIES OF THREE VARIETIES OF HIGH-OIL CANOLA AND ONE VARIETY OF LOW-OIL CANOLA.

Seed major and minor axes of three canola varieties with high oil content (45H29 at 8%, 10%, and 12% moisture content wet basis, and Invigor 5440 and Nex4 105 at 10% moisture content) and one low-oil canola variety (5525 Clearfield at 10% moisture content) were measured at room temperature. Bulk density, angles of repose, and coefficients of friction against four structural surfaces were determined for two varieties of high-oil canola (Invigor 5440 and Nex4 105) and for mixtures of them (at ratios of 1:1, 1:2, and 2:1) at four moisture contents (8%, 10%, 12%, and 14%). The same physical properties were determined for the third high-oil canola (45H29) and for the low-oil canola (5525 Clearfield) at three moisture contents (8%, 10%, and 12%). The four structural surfaces were galvanized steel, plywood, wood-floated concrete, and steel-troweled concrete. Major and minor axes of 45H29 increased with increasing moisture content. Oil content did not affect the axes of canola seeds. Bulk densities were significantly different between Invigor 5440 and Nex4 105. Mixtures of the high-oil canola varieties had bulk density values between those of the canola varieties that were used in the mixtures. Bulk density decreased with increasing oil content. Angles of repose depended more on canola variety and surface properties than on oil content. The coefficient of friction against structural surfaces was not significantly affected by moisture content but was affected by oil content. Bins used to store low-oil canola could also be used to store high-oil canola. [ABSTRACT FROM AUTHOR]
