CLOVE
Scientific Name : Syzygium aromaticum
Family : Myrtaceae
Chromosome number :- 22
Origin place :-Molluccas Island of Eastern Indonesia
The clove is one of the important tree spice crop grown in India.
The clove of commerce is the fully grown but unopened aromatic dried flower bud of an evergreen tree syzygium aromaticum.
The term 'clove' is derived from the French word 'cloy' and the English word 'clout', both meaning 'nail.The volatile oil obtained from the clove bud contains mainly (80-90%) and caryophyllene (4-8%).
Area and Production:-
In India the clove is cultivated in an area of 2,600 ha. with annual production of 1,160 tonnes. The productivity is 400 kg/ha.
Botany :-
The clove is an evergreen tree growing to a height of 7-15 m.
It begins to fork near the base, into two or three main erect branches. The smaller branches are semi-erect, the twigs are brittle, smooth and greyish-white in colour, and the whole head is bushy and dense.
The leaves are simple, opposite, exstipulate, glabrous and aromatic owing to plenty of oil glands on the lower surface. The new leaves appear in flushes and are bright pink.
The hermaphrodite flowers are borne on a terminal, corymbose, trichotomous panicle.

Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

BOTANICAL DESCREPTION
7. FLORAL BIOLOGY OF FOENICULUM VULGARE
Inflorescence :-
The Inflorescence of Fennel is referred as
Compound Umbel with subtended Involucre
of bracts and appears terminally on the plant.
One Plant may produce 11 to 30 Umbels. Each
umbel may have 4 to 22 umbellate containing
4.0 to 7.0 florets per umbellate.
Schizocarp
Pedicel
8. Calyx:-
Sepals are Five and are Gamosepalous (fused).
Corolla :-
Petals are Five in number and are Polypetalous
(free).
Petals are Brightly yellow in colour.
Each Umbel has long stalk, slender, curved, often
unequal in lengths.
9. Androecium :-
Androecium consists of Five stamens.
The Anthers are Bilobed, Introrse, Dorsifixed.
The Filaments are free. The Anthers splits longitudinal for
the dehiscence of anther.
Gynoecium:-
Gynoecium is Bicarpellary, Syncarpous, Bilocular with
Epigynous (inferior ovary).
The Pair of styles swells and spreads at the base forming
stylopodium (for attracting the bees).
11. Flower:-
Small, Yellow flowers are found in fennel.
15-20 flowers are found in an umbel with long stalk.
Flowers are Bisexual or Hermaprodite.
A strict sequence of blooming is observed in Centrifugal manner (Inner to outer).
First Umbel takes 84-90 days, while that of the last umbel takes 113-121 days for
opening after the date of sowing.
Pollination :- (Highly Cross Pollinated Crop)
Flowers are Protentous and Hence highly cross pollinated.
Both Wind and Insect pollinations are considered to be active.
13. SELECTION OF AGRO-CLIMATIC CONDITIONS
Fennel is A Cool season crop mainly grown during winter season. So A dry and
cold weather favours higher seed production.
A Temperature of 15-20°C is the Optimum. The Optimum temperatures for seed
germination is 25-29°C.
Above 25°C for extended period usually retards development and in early
growth may result premature flowering and may reduce the Seed yield.
Crop is susceptible to frost injury at flowering stage.
High Winds at the time of maturity can cause shattering and very hot winds at
flowering reduce seed setting.
14. SELECTION OF SEED PLOT
The Plot Selected for Seed crop must be
free from Volunteer plants, weed plants and
have good soil texture and fertility.
The soil of the seed plot should be
comparatively free from soil borne diseases
and insects pests.
Soil:-
Well drained Loamy soil or Black or Sandy soil rich in organic matter is suitable for
fennel cultivation.
However, Heavy soils are more desirable than light soils.
A Neutral to slightly alkaline soil in the range PH 6.5-8.0 is preferable
15. Isolation of Seed Crop :-
The Seed crop must be isolated from other nearby fields of the same crops and the
other contaminating crops as per requirement of the certification standards.
Preparation of Land :-
The First Ploughing should be done by soil turning plough and afterward 2-3
ploughing should be done by cultivator or harrow.
The Ploughed field should be made fine and leveled by planking. There should be
moisture in soil for good germination.
Add FYM 10 t/ha before last ploughing.
Form beds and channels.
16. SELECTION OF VARIETY
The Variety selected for Seed production must be carefully selected, should pocess
following Characters:-
Disease resistance
Earliness
Seed quality
Higher yielder
Adapted to the agro-climatic conditions of the region.
Source of getting the Seeds should be well known and should be of proper seed class.
17. Fruit :-
Fruits are oblong with Persistent style.
Fruit is considered as Cremocarp of Schizocarp type of fruit. It mean two one
seeded mericarps split along the carpophore.
Seed:- (Oblong or Curved in shape)
Seed is Endospermic and Green to Gray in colour.
19. SEED TREATMENTS
Seed treatment is an important practice for control of seed and soil borne
diseases. So it is necessary to treat the Seeds.
So before Sowing seed treatment with Bavistin or Captan or Thiram @
2.5g/kg seeds is done or Treat with Trichoderma @ 6.0 g/kg seed especially
for organic fennel production.
Seed soaking in water for 6 to 8 hours before sowing is found to increase the
germination percentage (82%).
20. TIME OF PLANTING
The Seed crops should invariably be sown at their normal planting time.
Depending upon the incidence of diseases and pests, some adjustments, could be
made, if necessary.
The Sowing of Fennel may be done in both late Kharif and Rabi season .
For Early fennel, Seed is sown in nursery in the month of June-July and 45-60
days of sowing in nursery. Seedlings of fennel should be planted in the main field.
The First fort night of October is ideal for direct sowing of the fennel as main
season crops.
Season:
Hills: May - June
( Transplanted type)
Plains: October - November
21. Seed Rate :-
The Lower seed rates than usual for raising Fennel crop is desirable to
facilitate rouging operations and inspection of seed crops.
For Direct sowing:- 9 – 12 kg/ha.
(not preferred for Seed Production)
For Transplanting:- 3 – 4 kg/ha – Nursery area 100 sq.m.at a spacing of 60 x 30
cm
Thinning
:-
In case of Direct sown crop thin 4 – 5 weeks old seedlings to aspacing of 25 – 30 cm
is done.
Depth of Sowing :-
The Seeds are sown at depths of 1.5 to 2 cms.
22. Spacing :-
Row spacing of 60 cm in heavy soils and 45 cm in light soils are desirable to
obtain better seed yield.
Roughing :-
Removal of Offtypes, diseases plants, unwanted plants of other crops etc from
seed crop is referred as Roughing.
The Adequate and timely field inspections are to be done to maintain The purity
of seed crop.
Rouging in fennel may be done at the following stages as per needs :-
1. Vegetative / Pre-flowering stage
2.
Flowering stage
3. Maturity stage
23. For Good production of fennel, About 15 tonnes/hac well decomposed FYM
should be applied at least 3-4 weeks before sowing.
In the early growth, stage of fennel if plant seems week, then spray 1% urea on
the crop 3 weeks after sowing.
MANURES AND FERTILIZERS

N (Kg/hac) P (Kg/hac) K (Kg/hac)
Top Dressing 25 10 0
Basal Dressing 25 0 0
24. CRITICAL STAGES OF IRRIGATION
Fennel crop requires more number of irrigation due
to longer duration of the crop.
Depending up on the temperatures and type of soil
6-8 irrigation during growth period is needed. The
irrigation interval should be kept 15-20 days.
Immediately after transplanting irrigation should be
given.
In direct sowing seed crop light irrigation is given
immediately after sowing if initial moisture is low.
Irrigation at 4 days interval with pressurized and
low pressure drip have been found very effective.
25. The Fennel crop growth is slow for first 50 days. Therefore, It is prone to
severe weed crop competition.
To harvest good yield it is necessary to keep crop weed free. About 2 to 3
weeding and hoeing is required.
Pre-emergence application of Oxadiargyl @ 75 /hac with one hand
weeding at 45 DAS has been very effective for ensuring effective weed
control of the fennel crop.
Two or three weedings are necessary. The plants are earthed up after 3
months. Pre-emergent application of Pendimethalin @ 1 kg a.i./ha and one
hand weeding.

27. HARVESTING
The Fennel Crop matures in 170 to 180 days.
Harvest the umbels 4 - 5 times at 10 - 15 days intervals because the all
fruits does not mature at a time., dry in sun for 4 - 5 days and seeds are
threshed.
Umbels are Plucked when fruits have changed their colour from green to
yellow and are fully mature.
For Green fennel, Umbels are harvested about 30-40 days after flowering when
these are still green and have attained half length size.
28. SEED YIELD ( Kg/hec or Qt/hec )
An Average yields of 12 to 13 qt/ha can be harvested.
29. DRYING AND STORAGE OF SEEDS
Harvested Umbels should be dried in shade under well aerated conditions
particularly for green fennel.
Umbels should never be piled as it may deteriorate the quality. The dried
umbel are separated and cleaned by winnowing.
The Proper care should be taken to prevent the Mechanical deterioration
during handling of seeds.
After Drying, Seeds should be Stored in Gunny or cloth bags in Storage unit.
31. ECONOMICAL IMPORTANCE OF CROP
Fennel is mainly cultivated for its seed which has a pleasing fragrance and
aromatic taste.
The Seeds act as stimulants and are carminative. They are used to aid diseases
like cholera, nervous disorder, cough and cold, constipation, dysentery and
diarrhea.
The Essential oil in Fennel is in a range of 1.5 – 6.5 percent, yellowish green
liquid, which having main constituents are 50-60 percent, anithole and 10-25
percent fenchone
These Essential oil of fennel has been use for treating Post menopausal
syndrome (PMS) and regulates menstrual period.
Owing to antimicrobial properties it is used in cosmetic creams, body lotions
and moisturizers.
