Página 30 - Plums, and Peaches upon Peaches or Almonds, the scion is, in regard to fertility, exactly in the same state as if it had not been grafted at all. While, on the other hand, a great increase of fertility is the result of grafting Pears upon Quinces, Peaches upon Plums, Apples upon Whitethorn, and the like. In these latter cases, the food absorbed from the earth by the root of the stock is communicated slowly...
Página 116 - 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.
Página 117 - Cross fertilization is effected, as every one knows, bj 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 15 - The great object in the application of manure should be to make it afford as much soluble matter as possible to the roots of the plant : and that in a slow and gradual manner, so that it may be entirely consumed in forming its sap and organised parts.
Página 32 - When the white frosts appear, the straw should be removed, and the tree remain uncovered, until the blossoms put out in the spring. " ' By this process, the fly is prevented from depositing its egg within three feet of the root ; and, although it may place the egg above that distance, the worm travels so slow that it cannot reach the ground before frost, and therefore is killed before it is able to injure the tree.
Página 118 - It seems that cross fertilization will not take place at all, or very rarely, between different species, unless these species are nearly related to each other : and that the offspring of the two distinct species is itself sterile, or if it possesses the power of multiplying itself by seed, its progeny returns back to the state of one or other of its parents.
Página 117 - When a grain of pollen comes in contact with the stigma, it bursts and discharges its contents among the lax tissue upon which it has fallen. 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. Once deposited there, the particle swells, increases gradually in size, separates into radicle and cotyledons, and finally...
Página 26 - Stocks for budding may, in general, be much smaller than for grafting, as the operation may be performed on the same year's shoot. But it may also be performed on shoots or stems of several years' growth, and in such, by inserting a number of buds, a complete tree may be formed at once.
Página 42 - I have observed, in other persons' grounds, where less space is allotted for this purpose, that great damage is done to the plants and fruit, by the trampling of the people. After the beds are planted, I always keep them as clear of weeds as possible, and on no account allow any crop to be planted between the rows. Upon the growing of the runners, I have them cut when necessary : this is usually three times in each season. In the autumn, I always have the rows dug between ; for I find...
Página 27 - ... then, directly with the thumb and finger, or point of the knife, slip off the woody part remaining to the bud ; which done, observe whether the eye or gem of the bud remains perfect ; if not and a little hole appears in that part, it is improper, or, aa gardeners express it, the bud has lost its root, and another must be prepared.
