The Seven Species of Israel
The life cycle of
Wheat
•
Seedling Stage
Seedling Stage
• The first stage of growth in
wheat is called the seedling
stage. This stage occurs
after germination and begins
when the first true leaves
emerge from the soil, and
ends when the first tiller
emerges. During the
seedling stage the second
leaves are just emerging
and beginning to unroll, and
there are as many as six
seminal roots.
Tillering Stage
•
Tillering Stage
• Tillers are new shoots that are sent up from the root of the plant. Each
tiller can grow its own stalk and seed head, so the number of tillers will
determine the potential yield of the plant. Tillering can occur either before
or after the winter dormancy stage in winter wheat, and a plant can have
as many as six tillers. Tillers can be distinguished from true leaves by a
sheath at the base of the growth called a prophyll.
•
Jointing Stage
• The jointing stage starts when the stalk forms its second node, a hard
joint from which the plant telescopes upwards. During the jointing
stage, the smaller, less-formed tillers often die off. It is important that
all the wheat in a field reaches the jointing stage at the same time so
that the heads will all be mature at harvest time.
•
•
Heading and Flowering
Stage
Heading and Flowering Stage
• The heading and flowering stage
begins when the awns emerge
from the sheath. When the awns
have emerged the flowering
begins and pollination and
fertilization occurs. It is important
again during the flowering stage
that all the plants in a field flower
at the same time. Right after
fertilization, the embryo and
endosperm begin to form.
• Booting Stage
• During the booting
stage, the head of the
wheat develops and
becomes visible
beneath the sheath on
the stalk. The booting
stage ends when the
tips of the head, called
awns, begin to emerge
Maturity Stage
Maturity Stage
• The maturity stage immediately
follows fertilization, and includes several
short stages. The milk stage is the first
part of maturing, and this is when the
kernel begins forming. The kernel is fully
formed during the dough stage, and the
plant takes nutrients from the stalk and
leaves and transfers them to the kernel.
The kernel is still very moist at the end
of the dough stage and contains about
30 percent water. During the ripening
stage the kernel loses the rest of its
moisture and is ready to be harvested.
The Life Cycle Of Barley
•
Seedlings

•
Geographic
Range
Geographic Range
• Barley grows in more regions than any other cereal
plant. The most common places to grow barley in the
United States are North Dakota, Washington, Montana
and Idaho
Climate
• Climate
•
• Barley prefers mild winter climates that are cool
and dry. It adapts easily to higher altitudes with
short, cold winters
• Soil •ConditionSoil
• This grain
does well in
semi-arid
conditions. It
can tolerate
alkaline soils
but does not
thrive nearly
as well in
acidic soils.
Condition
•
Maturation
Barley matures at a
quicker rate than most
other cereal plants.
The amount of days to
maturation depends
on the variety you
choose. The grain is
mature when the
kernel moisture dips
to about 40 percent.
Barley will grow to 30
inches in height
depending on the
variety.
The Life Cycle Of Grapes
•
•
Bud break
Bud break is the first stage after the
plants start coming out of their
dormancy. Prune grapes during
dormancy; this is critical for bud
development. The newly appearing
buds are susceptible to damage from
frost and hence need to be protected.
Dependent on specific weather
conditions, the new leaves commonly
appear three to four weeks after bud
break. This is also the time when the
vines maximize their food storage
through photosynthesis. Grapevines
are also prone to powdery mildew
disease during this stage, which can
be controlled with the use of antifungal
sprays. The plants can also show extra
shoot growth and these have to be
removed so as to maximize the energy
for the optimal development of flowers.
Flowering
•
The vines start to develop flower
clusters within about 10 weeks of
the initial bud break. This is usually
in May or early June. The period of
flowering is determined by the
grape variety and the weather
conditions in the area. This is also
the time for the pollination of the
flowers, which is necessary for the
formation of the fruit. Very hot
temperatures and heavy rain can
impede good pollination. It only
takes a week or two for the flowers
to get pollinated and if the weather
is not right during this period it
results in a smaller sized fruit.
•
Fruit Set
◦
In the fruit set stage, the
pollinated or fertilized flowers start
to turn into grapes and the flowers
that were not pollinated drop off the
tree. Young fruit needs to be
protected from night chills or any
frosts in the area. The grapevines
need heavy watering at this stage
to prevent the berries from drying
out. The fruit cells undergo division
in this stage and continue to get
larger. Thin shoots and leaves on
the vines frequently to create ample
space to accommodate the growing
grapes. Protect the fruits from
bright and direct sun at this stage
as this can cause sun scald.
Veraison
•
Veraison refers to the coloring of
the grapes and the stage is
characterized by the color
development in the fruit and
their softening. The softening of
the fruit is the result of the
accumulated sugars in the
grapes and can also be
considered the ripening stage.
The color of the grapes is
directly determined by the
variety. In order to produce a
good color many growers lift the
canopy or shade from the vines
at this stage. Veraison continues
till late July and then tapers off.
Harvest
•
The last stage comprises of
harvesting the mature grapes.
Again the final maturity time of
the grapes is dependent upon
variety. Generally the period of
maturity is reached about 100
days after the development of
flowers. The grapes are first
tested for sugar and acid levels
before they are harvested. The
life cycle of the grapevines ends
in the fall and the plants start to
recede into dormancy and their
leaves start to fall off. Pruning is
critical during dormancy as this
protects the plants from periods
of extreme frost.
Growth Stages of a
Fig Tree
Germination
•
Fig seeds are
extremely hard to
germinate and have
very low viability.
Germination typically
takes a week. During
the germination stage,
the seed sprouts, roots
develop and the stem
begins to form.
•
Primary Growth Stage
Primary Growth Stage
• As a young sapling, the fig tree's root system establishes and expands, the stem of the tree grows and strengthens into what
will one day be a trunk. Primary branches develop out of the main root stem, and leaves begin to form on the low branches. After the
first year, the plant can begin to hold up to pruning.
• In this stage, it is only necessary to prune the plant to lightly shape it and train future growth. Ideally, you should not prune the
plant until it's mature.
R
•Secondary Growth Stage
Secondary Growth Stage
•
•
After a year, the fig tree enters the secondary growth stage. The first branches and bark grow more firm, secondary branches
develop and leaf development continues. Roots spread wider and harden, and bark forms to strengthen the trunk.

•Maturity
Maturity
•
•
Bearing fruit is the point of maturity for a fig tree. The branches and bark strengthen further to prepare for he weight of the
fruit. Fig trees bear fruit in two harvests: the first in the spring from the old growth, called the breba crop, and the second in
the fall, known as the main crop, with fruit harvested from the new foliage growth
After each harvest, you can prune the tree to maximize subsequent harvests and to maintain the desired shape of the plant.

Reproduction
•
1.
Reproduction
◦ The fig tree doesn't have a separate flowering stage since the flower actually develops in clusters inside the fruit itself,
where the pollinating insect will climb inside the fruit, technically the syconium, and find the flowers (most species of fig
pollinate this way).
Many domestically cultivated figs have been hybridized to be self-pollinating. In a self-pollinating fig tree, everything that is
needed for the plant's reproduction is inside its own fruit.

Age at Maturity
Many species of palms are relatively slow-growing trees. Depending on their growing conditions, some palms must be 10
years old or older before they begin to produce flowers, which if pollinated, grow into fruit such as dates or coconuts. Each date
contains one seed; each coconut is a seed unto itself. When these seeds are properly germinated, they produce another palm
tree.

Like humans and other animals, palm trees live for a predetermined number of years. For example, the Mexican fan palm,
an icon of Los Angeles, lives for about 100 years. Coconut palms live 80 to 90 years. Various date palms can live 100
years, but are often felled when they grow too tall to harvest or when they are about 45 feet tall. Areca palms live only 40
years.
