The Pollination of Fruit Trees

Abstract

INVESTIGATIONS carried out in this country, in America, and elsewhere have demonstrated the fact that many of our cultivated varieties of apple, pear, plum, &c., are self-sterile. They have shown, moreover, that whereas a variety may be sterile when pollinated with its own pollen, it yields an abundant crop if pollinated with the pollen of certain other varieties. Hence it is of considerable economic importance to discover which varieties serve best for mutual cross-pollination.
