r of different
varieties, for the purpose of obtaining seed, which shall produce new
and diverse kinds, combining in some degree the qualities of the
parents, and presumably of superior excellence. Accepting the foregoing
terms in the sense alluded to, as meaning simply a mixing of stocks, or
of varieties, there are two ways of securing the desired results, the
natural and the artificial. In the former, insects and the wind do the
work; in the latter, it is done by hand. It may be worth while to speak
of these methods somewhat in detail, with the prefatory statement that a
variety is not supposed to reproduce itself from seed, and as a rule it
does not. Although there are instances in which seedlings bear a close
resemblance to a parent, or to each other, theoretically no two are
alike, and in reality there is a wide range of variation among those
grown from the same bulb. In this variation lies the charm of the work
and the secret of success.
Suppose the grower wishes to cross two varieties in the natural way. He
plants the bulbs near together and apart from others, far enough distant
so that their pollen cannot reach the blooms. Between the two there is
an interchange, each being fertilized by the other, and the results will
comprise as many variations as there are seeds produced. Several kinds
may be planted together in the same manner and the consequent
combination will be still more numerous and varied. If the amateur
wishes to save seed from his bed of mixed bulbs, he watches the blooms
as they come out and cuts and carries away any that are not desirable to
propagate from, so that they may not affect the seed of the others. By
this method all the seed saved is of a high grade of excellence, and the
new developments from it are exceedingly interesting.
When the grower purposes to cross two varieties artificially, he goes
about it early in the morning, when the blooms first open. He selects
the flower which is to be the mother parent, cuts away the stamens with
sharp pointed scissors, and then covers it with cheese capping, to keep
out strange pollen. From ten o'clock in the forenoon to about four in
the afternoon, the pistil secretes a honey-like liquid, which causes the
end or stigma to be moist. It is then said to be receptive, and the
grower carries the stamens from the other parent, and gently touches the
stigma with the anthers, causing the pollen to adhere.
