3.2.1         Seed Characteristics



The mean values for various seed characteristics are presented in Table 1 [Pop-up]. A large proportion of the pelleted seed lots was in the form of the clay pelleting material, but after de-pelleting the mean seed weights of the pelleted seed lots (Lots 3 & 4) were similar to the mean weights of Lots 1 & 5.  However, the mean seed weight of Lot 2 was lower than the others.

 

The mean true seed weights of Lots 1, 4 & 5 were similar, while Lots 2 and 3 were lower and higher than the other lots.  The mean proportion of the total seed weight as true seed weight was similar for all the seed lots except Lot 3 which had a greater proportion than the others.  The moisture contents of the five seed lots were also similar.

The relationships between seeds and true seed weights are presented in Figures 1-5. [Pop-up]  Integers plotted on the Figures indicate the number of seeds with the same seed and true seed weights.

The relationships revealed highly significant correlations (P = 0.001) with Lots 2, 3 & 4, a good correlation with Lot 5 (P = 0.01) but a non-significant correlation with Lot 1.

The slopes of the regressions are slightly greater than 1 for Lots 2, 3 & 4 but much less than 1 for Lots 1 & 5.  There would appear to be an association between the correlation coefficient and the slopes of the regressions.  However when the actual true seed weights and mean proportions of the seed weight as true seed weight are compared Lots 1 and 5 have the largest and smallest standard deviations in both cases (Table 1 [Pop-up]).

The coefficients of variation for the true seed weights of all 5 lots are all larger than the respective coefficients for the total seed weights indicating that there is relatively more variation in the true seed weights.
