Página ix - Cross fertilisation is effected, as every one knows, by the action of the pollen of one plant upon the stigma of another. The nature of this action is highly curious. Pollen consists of extremely minute hollow balls or bodies; their cavity is filled with fluid, in which swim particles of a figure varying from spherical to oblong, and having an apparently spontaneous motion. The stigma is composed of very lax tissue, the intercellular passages of which have a greater diameter than the moving particles...
Página ix - The power of procuring intermediate varieties, by the intermixture of the pollen and stigma of two different parents, is, however, that which most deserves consideration. We all know that hybrid plants are constantly produced in every garden, and that improvements of the most remarkable kind are yearly occurring in consequence.

Striking from Cuttings is a slight modification of the last method. Instead of taking a single bud, a stem containing two, three, or more buds, is placed in circumstances fitted for the maintenance of its life.

The moving particles descend through the tissue of the style, until one, or sometimes more of them, finds its way, by routes specially destined by Nature for this service, into a little opening in the integuments of the ovulum, or young seed.

In proportion to the size or age of a tree, is the difficulty of preserving them increased; and hence, at the same time, the difficulty of transplantation is augmented. If, by any method, the...
Página xi - ... is the communication between the one and the other as free and perfect as if their natures had been more nearly the same ; the sap is impeded in its ascent, and the proper juices are impeded in their descent ; whence arises that accumulation of secretion which is sure to be attended by increased fertility.
Página xiv - ... cambium, which serves as food for the young descending fibres, is secreted. It is obvious, that the more accurate the adjustment of the line separating the wood from the bark, the more ready will be the transmission of young fibres from the one to the other ; and that the less the accuracy that may be observed in this respect, the greater the difficulty of such transmission will be. Provided the stock and scion be of exactly the same size, the adjustment can scarcely fail to be accurate in the...
