ABSTRACT
The eggs of Dalahai are dark brown in color, very elongated, 1.1-1.33 mm long and 0.4-0.5 mm wide. The weight of one
thousand calf eggs was 0.11-0.12 g. As a result of the study of the ontogeny of H. perforatum, it was found that there
is a change in the color of the eggs, and it is not necessary to do scarification or stratification before bending.
KEYWORDS

Geographic distribution. Dalahai species grow on the
edges of fields, in salma bays, in pastures, in meadows,
in thickets, in thickets. It is used in Ukraine, Belarus,
Moldova, the Baltic countries, the European part of
Russia, in the highlands and steppes of Western
Siberia, in the Caucasus and in Central Asia.
Egg germination in laboratory conditions: Eggs appear
as a result of sexual reproduction of the plant and
serve in the distribution of eggs. The egg is released
after the process of fertilization, but in some cases, few
eggs may appear without ovulation (apomixis).
Nutrient elements and gills are present in the egg, so
it has a protective shell. Due to physiological changes,
some eggs fall out of the spore. Let the egg sit for a
while before it turns blue. The period of ovulation can
be different in different eggs, and when they are
stored for a long time, they do not change a little.
When the seed was fertilized with a spore, the result
was successful. As a result of maturation, the
endosperm is less developed, but as a result of the
enlargement of the pod, nutrients accumulate in the
pod and the endosperm shrinks, and the maturation
processes can also be accelerated.
In the process of cell development, the endosperm
develops, and as a result, the ovule becomes the
nucleus of the nucleus. But if the nucellus does not
digest the food element, it fulfills the role of
endosperm.
The ovules of the plants related to the ovules of the
angiosperms and the ovules were found to be
perispermic. Eggs are found in nature in various forms.
The surface of the egg is smooth, shiny, ribbed, and
hairy. The egg is united with the egg band - funiculis,
and in some cases with the stem. The embryonated
egg, eggshell, and food-gathering tissue (endosperm,
perisperm) are all derived from the stem. If the egg
shell does not hatch, the spermoderm emerges from
the egg shell intugument. The egg shell protects the
egg. Decomposition of the egg depends on the egg's
migration and spread.
The nutrient element was found in the endosperm and
perisperm of the egg. Nutrient elements were found in
individual eggs, but only in the stem. Nutrient elements
can be solid, liquid or liquid. They consist of
carbohydrates (protein, fat, starch).
The person that appeared as a result of the fertilization
of Murtak's iris cell became a sporophyte. Murtak is a
child, but Murtak can have a lot of thoughts. In this
case, other parts of the egg and the sperm participate
outside the testicle cell. Citrus, sebarga plant has many
buds.
Apomixis is called apomixis when a bud appears from
the development of one cell of an egg without
fertilization. It is called parthenogenesis, the
development of a larval cell without ovulation and the
formation of a follicle. Parthenogenesis takes place in
the caraway plant.
Maturation of the egg occurs before the completion
of
the
physiological
process.
Physiological
development stops, the entry of sugar into the egg
stops, as a result, the entry of nutrients into the egg is
stopped, the physiological processes of the child stop,
the hormonal activity of enzymes decreases, fertility
decreases by 5-10%. The shell of the egg thickens, and it
turns into wood in many cases. This state of ovulation
is called physiological state.
A lot of biochemical and physiological processes take
place during the hatching of the egg. When water
enters the egg shell, the process of respiration occurs,
the activity of enzymes accelerates, nutrients are
diluted and proteins are formed. As a result, if a leaf in

the mulberry tree sprouts a leaf on its surface, the root
of the stem will start to grow. If the plant that grows
from its seed has a high need for photosynthesis, its
seed will go to the surface of the ground and become
a green leaf, if more nutrients are needed, the seed
pod will remain under the ground. In order for the egg
to hatch, temperature, humidity and humidity are
needed (1:94-b).
Itroduction is important for the development of each
stage of the plant, and therefore the order of its
individual development (ontogeny). Egg laying is a
productive process, and it is one of the adaptive
features of the herd.
Our experiments show that in laboratory conditions,
the eggs begin to migrate after 13-14 days. On the 18-
20th day, the leaves of the ovary close together and
the yellow color is invisible [2: 183-184-b]. Dalashay
eggs were placed in a petri dish on November 28 for
the purpose of the experiment. 100 eggs were placed
in each petri dish.
The experiment was carried out in four stages. The
hatchability of eggs was studied at temperatures of 5,
10, 15, 20, 25, 30, 35, 40 and 45°C (Table 1).
The number of eggs of Dalashay shows the strength of
the egg. Hatchling power depends on the temperature
level, and the lowest temperature was 5°C, hatching 5,
7 eggs in 24 days. It has been found that the
temperature is increasing - it is changing to a more
favorable temperature.
For example, at a temperature of 10°C, the yield
strength increased to 9.8% and was observed on the
16th day after sowing. Bul pointer at 15°C 14 t copy 11.3%
at 20°C
14th day to 15.6%, 25°C day 10.4% 111, 30°C day 16
28, 3% was equal to 53, 3% after 14 days at 35 °C. The
hatching time of the eggs was 1-14 days and the best
hatching power was observed at the temperature of
35°C.
The influence of temperature on the germination of
Dalasay plant eggs. In the course of the development
and ontogenesis of the Dalasay plant, learning has
gained a special importance in the production of plants
by creating a special condition and culturalizing them.
Growth is one of the most important processes in plant
life, and all physiological and biochemical reactions
occur in the plant species, resulting in increased mass
and productivity. Growth begins with the process of
ovule shedding, and ovule growth is related to the
enzymatic processes in the endosperm of the ovule,
which absorb water.

H. p e r f o r a t u m was studied under the influence of
temperature in different seasons. The production
temperature is an important ecological factor in the
germination of seeds. In a Petri dish, 100 seeds of good
quality were separated for this purpose.
Study was taken in 4 conditions. We were able to store
the products at temperatures of 5°C, 10°C, 15°C, 20°C,
25°C, 30°C, 35°C, 40°C and even 45°C. The seeds took
several days to hatch at a temperature of 5°C, but after
24 days they started hatching, and in the end, only 10.3
hatched out of 100 eggs.
The tumor that appeared was also weaker. As the
temperature increased, the shedding of the eggs also
increased. At a temperature of 10°C, the maximum
germination was observed in 16 to 17 days, and in this
steady state, an average of 9.8 to 8.1 seeds were
germinated. At the end of the period, the number of
eggs that were hatched was 24.5 or 24.5%. At a
temperature of 15°C, 11.3-26.3% of seeds were
harvested on the first day of the test, 8.1 days on the
15th day, and 26.3 days on the 15th day. As the
temperature increased, the number of hatched eggs
also increased, and on the 14th day at 40°C, 20 eggs
were hatched, and on the 15th day, 4.9 eggs were
hatched, making a gain of 25.2%. At 45°C, the seed
germinated 9.3 times on the 14th day and yielded 9.3%,
but did not germinate on the following days.
It was determined that the optimal temperature for H.
perforatum seed germination is 35°C. In this variant,
after ovulation, 13 days, 15, 4, 14 days, 53, 3, 15 days, 9,
3, 16 days, 4, 7 eggs were released, out of a total of 82,
7 eggs were released, making 82.7%.
At 40°C, 20, 3, 4, 9 eggs hatched on the 4th day. At this
temperature, the hatching process is not observed in
the following days. At 45°C, on the 14th day, 9, 3 eggs
hatched, and the hatched eggs darkened (shriveled) in
3-4 days.
So, it was found that the temperature has a certain
physiological effect on the hatching of eggs.
It should be noted that pilislew development was
observed in the eggs at the temperature of 35-40°C. At
corretogenic temperatures in Joghar, the eggs
hatched fully within fourteen days after hatching
(Table 1).
As a result of the experiment, the left thing was
known,
It was found that the average temperature of H. p e r
f o r a t u m egg hatching is 30-35°C, and the optimum
temperature is 35°C.
