from The Century Dictionary.
- noun In botany, the inability of a flower or plant to fertilize itself.
Sorry, no etymologies found.
Another large tree in eastern Virginia produces many burs but the nuts fail to develop, indicating self-sterility.
Other factors, such as self-sterility, may be wholly responsible for at least the lightness of crops.
In the self-sterility of filberts the failure of self-pollination results in an absence of nuts or in very few rather than a full crop of seedless fruits such as the common chestnut and the Weschcke black walnuts produces.
All these methods are common, except perhaps the second; but there are many flowers in which the pollen from another plant is prepotent over the pollen from fertilisation, the same flower, and this has nearly the same effect as self-sterility if the flowers are frequently crossed by insects.
This paper gives a full account of the self-sterility of Oncidium in cases where the pollen was efficient in fertilising other individuals of the same species and of distinct species.
I am sorry about delay [of] your orchid paper; I should be glad of abstract of your new observations of self-sterility in orchids, as I should probably use the new facts.
