How bees collect resin to produce Green Propolis
Bees visit the plants, cut the vegetative apex with their jaws. Then, they carry the resin together with leaf fragments, glandular trichomes, non-glandular trichomes, crystals of oxalate of calcium, secretory disks and pollen grains that determined the vegetal species visited.
The green propolis produced in the State of Minas Gerais (Brazil) was characterized by means of microscopic analysis of its sediment. In it we could find glandular trichomes, non-glandular trichomes, fragments of epidermis and pollen grains of Baccharis dracunculifolia. We can see below the visiting of the bees to the plant in order to collect resin.
