English:
Stigmatic Chestnut Blossoms: Hand pollenizing of the chestnut is effected with the greatest facility, nothing more being required than to pluck a pollen-bearing branch, like that shown on the opposite page, and dust it lightly against such a stigmatic branch as this. Mr. Burbank has produced remarkable results by hybridizing chestnuts from Japan with European and American species. Some hybrids are immune to the fungus that destroys the American chestnut.

Text Appearing Before Image:
Pollen-Bearing Chestnut Blossom The chestnut bears its pollen and its ovules separately. It depends largely on the wind to transfer the pollen, and hence does not develop a conspicuous floral envelope to attract insects. the massed blossoms, in spite of their small individual size, are conspicuous, as this picture shows. The pollen is produced in relatively enormous quantities. But <

The essential thing is to secure a certainquantity of pollen, usually by shaking it fromthe flower on a watch-crystal or other smallreceptacle, and to transfer this pollen to thereceptive pistil of another flower either with thefinger tip—which furnishes in general the mostuseful piece of apparatus—or with a camels hairbrush. It is desirable to cover the receptive portion(stigma) of the pistil fully with pollen, partlyto ensure complete fertilization, and partly toprevent the vitiation of the experiment throughpossibl
