早已发现蜜蜂对蜜源植物有选择性。原因之一是蜜蜂的授粉专一性,对所采花粉的化学成分有一定要求。在非黑钙土地带,荞麦是主要的蜜粉源。佩雷尔松,И.Е.(1962)发现植物的泌蜜量和花粉中粗蛋白含量的相互关系。在荞麦花粉中粗蛋白含量为14.12％,其他植物为22—29.6％。现已查明荞麦花粉中一 Bee has long been found to be selective for nectar plants. One of the reasons is the pollination specificity of the bees, which has certain requirements on the chemical composition of the pollen collected. In non-Chernozem buckwheat is the main source of honey. Perelsson, И.Е. (1962) found that the relationship between plant secretion of nectar and the content of crude protein in pollen. In buckwheat pollen crude protein content of 14.12%, other plants 22-29.6%. Has identified one of the buckwheat pollen
