If you s seed from your own plants you are able to cho
carefully. Supp
you are sav
seed of aster plants. W
blos
s shall you decide upon? Now it is not the blos
only which you must consider, but the e
re plant. Why? Because a weak, straggly plant may produce one fine blos
. Look
at t
one blos
so really beautiful you think of the numberless equally lovely plants you are go
to h
from the seeds. But just as likely as not the seeds will produce plants like the parent plant.
So in seed selecn the e
re plant is to be consid
d. Is it sturdy, strong, well shaped and symmetrical; does it h
a goodly number of fine blos
s? These are ques
ns to ask in seed selec
n. If you should happen to h
the opportun
to visit a seedsman's garden, you will see
e and t
e a blos
with a str
tied around it. These are blos
s ch
n
seed. If you look at the whole plant with care you will be able to see the points which the gardener held in mind when he did
work of selec
n.
In seed selecn size is anot
point to hold in mind. Now we know no way of tell
anyth
about the plants from which t
special collec
n of seeds came. So we must give our e
re thought to the seeds themselves. It is quite evident t
t
e is
e choice;
e are much larger than the ot
s;
e far plumper, too. By all m
s cho
the largest and fullest seed. The reason is t
: When you break open a b
and t
is very evident, too, in the p
ut you see w
appears to be a little plant. So it is. Under just the right condi
ns
development t
'little chap' grows into the b
plant you know so well.
T little plant must depend
its early growth on the nourishment stored up in the two halves of the b
seed. For t
purp
the food is stored. B
s are not full of food and goodness
you and me to eat, but
the little baby b
plant to feed upon. And so if we cho
a large seed, we h
ch
n a greater amount of food
the plantlet. T
little plantlet feeds upon t
stored food u
l its roots are prepared to do their work. So if the seed is small and thin, the first food supply insufficient, t
e is a possibil
of los
the little plant. You may care to know the name of t
pantry of food. It is called a cotyledon if t
e is but one por
n, cotyledons if two. Thus we are aided in the classifica
n of plants. A few plants t
bear cones like the pines h
several cotyledons. But most plants h
eit
one or two cotyledons.
From large seeds come the strongest plantlets. T is the reason why it is better and safer to cho
the large seed. It is the same case exactly as t
of weak children. T
e is often anot
trouble in seeds t
we buy. The trouble is impur
. Seeds are
etimes mixed with ot
seeds so like them in appearance t
it is impossible to detect the fraud. Pretty poor business, is it not? The seeds may be uncl
. Bits of
eign matter in with large seed are very easy to discover. One can m
ly pick the seed over and make it cl
. By cl
is m
t freedom from
eign matter. But if small seed are uncl
, it is very difficult, well nigh impossible, to make them cl
.
The third th to look out
in seed is viabil
. We know from our test
s t
seeds which look to the eye to be all right may not develop at all. T
e are reasons. Seeds may h
been picked be
e they w
ripe or mature; they may h
been frozen; and they may be too old. Seeds retain their viabil
or germ develop
power, a given number of years and are then useless. T
e is a viabil
limit in years which differs
diff
nt seeds.
From the test of seeds we find out the germinan percentage of seeds. Now if t
percentage is low, don't waste time plant
such seed unless it be small seed. Immediately you ques
n t
statement. Why does the size of the seed make a diff
nce? T
is the reason. When small seed is planted it is usually sown in drills. Most amateurs sprinkle the seed in very thickly. So a great quant
of seed is planted. And enough seed germinates and comes up from such cl
plant
. So quant
makes up
qual
.
But take the case of large seed, like corn example. Corn is planted just so far apart and a few seeds in a place. With such a method of plant
the matter of per cent, of germina
n is most important indeed.
Small seeds t germinate at fifty per cent. may be used but t
is too low a per cent.
the large seed. Supp
we test b
s. The percentage is seventy. If low-vital
seeds w
planted, we could not be absolutely certain of the seventy per cent com
up. But if the seeds are lettuce go ahead with the plant
.
