There has got to be a lot of changes in the kernel after they have once dried out and been harvested before germination will be initiated again.
It is probable that the nursing of the embryo had not yet come to be one of the functions of the seed, and that the whole embryonic development was relegated to the germination stage.
Third, often the foliage of the plant can be sprayed with a poison that will prevent the germination of the spores (see pp.
Of course, if the soil is rather warm and moist at planting-time, fewer seeds will be needed than when germination is likely to be slow.

Unfertilised eggs of insects have been started into growth by treatment with acids and those of frogs with mercury salts, and the germination of beans quickened by various poisonous alkaloids.
To the amateur, the process ofgermination and development from the seedling to the mature stage, is full of interest and attraction, the changes from one form to another as the plant develops being very marked in most of the genera.
The seedlings of these two genera serve as an illustration of the process of germination from seed of all the Cactuses; and it must be evident that there is much that is singular and full of interest in raising these plants from seeds.
For the germination of Cactus, and indeed of all seeds, a certain amount of moisture must be constantly present in the soil; and after a seed has commenced to grow, to allow it to get dry is to run the risk of killing it.
In one or two instances the entire spore swells up, lengthens and becomes a rod without any special germination unless this type might be designated bi-polar.
It may be at the end when the germination is said to be polar (Fig.
It may be from the middle of one side which gives equatorial germination (Fig.
In measures 50-51 occurs one of those cases of melodic germination which entitles Brahms to be called a genuine creative artist.
Music] Abounding in fascinating modulations and coloristic effects it shows Franck's genius equally for real melodic germination with an avoidance of all perfunctory manipulation of his material.
Cooling inhibits the germination and growth of this organismal residue.
It was comparatively easy to keep out foreign germs from a cover-glass preparation enough to perceive germination of spores and growth of mycelium.
If a good germination takes place it is more difficult to thin the chile, because there are more small plants to the hill to be pulled out.
If too low, the hill will become water-soaked in case of rain and the seeds or plants injured; if too high, there is likely to be insufficient moisture to insure proper germination and growth.
Shallower planting does not as a rule give as satisfactory germination as planting within the range above mentioned.
Where vacant places occur from failure in germination they may be filled in by transplanting.
One of the first signs of promise for early cantaloupes is a quickgermination and rapid development of large cotyledons.
If the eyes appear dormant in spring, seed potatoes may be exposed to the light and warmth for a few days before planting so as to promote germination and prompt growth.
So far as we know at the present, many mushrooms may or may not produce their young through the germination of their spores in their native fields and meadows and the subsequent production of male and female reproductive organs.
The comparatively minute fraction of them that ever do find congenial surroundings, once they are expelled from the spore case, then begin a process that is not unlike the germination of a seed.
It prevents the germination and growth of nearly all the seeds falling from such trees, and in a really virgin forest of this sort, almost no seedlings will be found.
Some few seeds which would usually be dormant for one, two or even three years, have their germination unquestionably hastened by passage through birds, who may be looked on in some cases at least as “flying germinators.
And perhaps the most remarkable case is the seed of a pondweed said to be incapable of germination until it has passed through a bird.
But in most mushrooms no one has ever seen, nor have the most carefully conducted experiments ever demonstrated the germination of the spore.
It were perhaps well to note here that popular stories about the germination of grains of wheat taken from Egyptian mummies are not true.
Germination of Samples of Common and Swede Turnips.
Germination of Ten Sorts of Turnip Seeds from Market Samples.
Prepare hanging-drop cultivations from old cultivations in which no living vegetative forms are present, and observe the process of germination in a similar manner.
At the end of this time the non-sporing bacteria are dead, and cultivations made from the mixture will yield a growth resulting from the germination of the spores only.
During the last two years, I have had good results in germination by stratifying the nuts under the trees, just as soon as they fall.
By this plan, I have had from 60 to 90 per cent germination during the last two years.
To determine whether time of outdoor stratification has any effect on germination and emergence, three other seedlots were treated as follows: 1.
Regardless, however, of temperature or other conditions, germination is likely to begin in early March and nuts intended for planting should be hastened into the ground as promptly as possible after that time.
Since this is the case, you can see that germination may be very poor, unless they are handled in a special way.
All of the sound nuts in these lots were planted in a rodent-proof coldframe immediately after they were removed from storage, and from 90 to 95% germination of the seed was obtained throughout.
Germination was higher for nuts planted in the fall than for nuts stratified on the same day for spring planting, although the difference was significant only in the second test.
Any delay after November 28 resulted in reduced and retarded germination and consequently smaller seedlings.
Results~: With one exception where germination was poor, nuts with small kernels produced small seedlings and nuts with large kernels produced large seedlings.
Depth of Planting and Seed Orientation The effect of planting depth on germination and on seedling size was investigated by planting black walnuts one, two, three, and four inches deep.
Results~: Germination was unaffected by any of these treatments.
Germination and Stratification It is known that either fall- or spring-planted walnuts germinate readily if the nuts are viable and if those planted in the spring are properly stratified over winter.
While this treatment probably will not kill all the weevils it will insure a much larger percentage of germination than there would be otherwise.
As the stock feeds on the plants it tramples the seed into the ground and thereby furnishes favorable conditions for the germination of the seed.
Studies have been made upon the comparative germination of tree seeds in the field and the greenhouse.
With successful germination assured by the collection of good seed and the protection of it after it has been sowed from rodents, the next problem lies in cheap methods of cultivation and sowing.

The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "germination" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: development; flower; growth; maturation; outgrowth; procreation; reproduction; vegetation
