Experimental design and treatments: The experiment was conducted in a randomized complete block design with 3 replications and the treatments were 2 grass species (Chloris gayana and Panicum coloratum) and 2 forage legumes (Melilotus alba
and Medicago sativa) grown in pure-stands and in mixtures using a seed rate proportions of 50:50, 67:33, 33:67, 75:25 and 25:75 of the grass and legume component, respectively.
Diameter of the pollen ranged from the smallest 15um in Melilotus alba
to largest50um in Sophora mollis (Table-2).
Samples of Tetragonisca presented dominant pollen types of Carica papaya (Marilia-T), Eupatorium (Posse-T), Melilotus alba
(Pedreira-T) and Piptadenia (Itaberaba-T), characterizing monofloral honeys (Figure 1 a-f).
In the trials where fresh leaves and flowers were offered, the rejection was highest in trials with Convolvulus arvensis (88.75%), followed by Melilotus alba
(50%) and Echium vulgare (0 %; [Chi.sup.2]2 = 27.0, p < 0.001).
Though 10 exotic species were found during the present study, only Melilotus alba
(white sweet clover) and Medicago lupulina (black medic) were encountered in the plots, both with low IVs (Table 1).

However, certain nectar species, including Arabis lyrata, Coreopsis lanceolata, Melilotus alba
and Rubus flagellaris, were selected in a significant majority of cases when other nectar species were available nearby.
Three legume species, however - Lotus japonicus, Medicago truncatula, and Melilotus alba
(in the same tribe as Medicago) - have been identified as model plants for molecular genetics in legumes because of their small and manageable genomes (Handburg & Stougaard, 1992; Oger et al., 1996; Sagan et al., 1995; Utrup & Norris, 1996).
