An Interaction Between Pollinators and Reciprocals in an Alfalfa Cross1
- M. W. Pederson2
The extent of a reciprocal difference for seed and hay yield in a cross between two alfalfa clones was affected by the method of pollination. When compared to honey-bee pollination leaf-cutter bee pollination increased the difference by causing a higher yield of hay and seed with one clone as a female and a lower yield with the other clone as a female. Selfing on the more self-fertile clone is considered of importance in the reciprocal effect. However, the more self-fertile clone also has smaller seeds than the more self-sterile clone. Apparently the efficiency of pollen transfer between different alfalfa plants is different for leaf-cutter bees and honey bees.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
