a procedure of fecundation where the pollen tube penetrates into the embryosac through tissue of this chalaza, instead of entering through micropyle. It had been originally found by Treub in Casuarina, and it has because already been discovered to occur regularly into the households Betulaceæ and Juglandaceæ. Limited chalazogamy is situated in Ulmus, the pipe right here penetrating the nucleus midway involving the chalaza and micropyle.
In botany, fertilization through chalaza.
A process of fecundation in which the pollen tube penetrates to the embryosac through the tissue of the chalaza, instead of entering through the micropyle. It was originally discovered by Treub in Casuarina, and has since been found to occur regularly in the families Betulaceæ and Juglandaceæ. Partial chalazogamy is found in Ulmus, the tube here penetrating the nucleus midway between the chalaza and micropyle.
