Priming improved all tested germination traits of both genotypes, such as the mean germination time, coefficient of uniformity of germination (CUG), coefficient of velocity, germination capacity and percentage (GC) of abnormal seedlings.

The purpose of the study, composed of two experiments, was to find an effective and suitable way of cluster osmopriming that would improve the germination parameters, such as the mean germination time, coefficient of uniformity of germination, coefficient of velocity, germination capacity and percentage of abnormal seedling of new red beet monogerm breeding line AR79.

where [h.sub.m] is height of material layer during aeration, [h.sub.f] is height of fluidized bed at the minimum velocity, [[phi].sub.A] is coefficient depending on the porous membrane, v = 10 x [v.sub.vf] is air speed calculation on the total surface of the air-slide conveyor (this ratio of velocity depends on the type of material being transported), v = 10 x 0,671 x [10.sup.-2] = 0,0671 m/s is air velocity and m = 0,5 is

coefficient of velocity [4],

where, [K.sub.V] is the compensated

coefficient of velocity.

The coefficient of velocity Cv where obtain by using Vo where Cv is V / Vo.

Figure 4 show the coefficient of velocity Cv, data against the point inside the diffuser (Xo) over the distance between the 2 diffuser (D).

Kotowski's coefficient of velocity (Scott et al., 1984) was calculated as an estimate of rate of root emergence:

Significance of F tests for ANOVA (analysis of variance) of cumulative root emergence, days to 50% root emergence ([E.sub.50]), and coefficient of velocity of root emergence ([COV.sub.E]), and Wilk's [Lambda] for MANOVA (multivariate ANOVA) of cumulative root emergence.

Coefficient of velocity of germination (CVG), germination index (GI), germination rate index (GRI), mean germination time (MGT), final germination percentage (FGP), germination rate (Rs) and mean daily germination (MDG) were calculated using the following formula [7]:

1) The coefficient of velocity of germination (CVG): [summation]NiTi / [summation]Ni x 100 = CVG

Coefficient of velocity of germination (CVG) indices evaluates drought stress tolerance.

In this experiment, Coefficient of Velocity of Germination (CVG), Germination Rate Index (GRI), Final Germination Percent (FGP) and Germination Index (GI) were calculated for method of AL-Mudaris [3].
