Excerpt from The Pomological Manual, Vol. 2: Or, a Treatise on Fruits: Containing Descriptions of a Great Number of the Most Valuable Varieties for the Orchard and GardenThe power of procuring intermediate varieties by the intermixture of the pellen 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. Experiments are, however, it maybe supposed, sometimes made without the operator being exactly aware either of the precise nature of the action to which he is trusting for success, or of the limits Within which his experiments should be confined.Cross fertilization 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 consist of extremely minute hollow balls or bodies their cavity is filled with ¿uid, in which swim particles, of a figure varying from Spherical to oblong, arid 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 of the pollen.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
