Yield and storage
Yield:
Storage:
It is one of the most
important stone fruit .
It is very delicious,
attractive & nutritious fruit
Rich source of Vitamin A
It can be grown in areas
where other temperate fruits
are not grown because it is
drought tolerant, salt tolerant,
hardy and less susceptible to
pest and diseases
Highly perishable fruit.

COMPOSITION
Rich source of vit A, fat, fibre, ascorbic acid, Ca
Rich source of oil (40-45%)
Aroma of fruit is due to Benzaldehyde and Lindrol
Major acids present are Mallic acid and Citric acid
Contains higher amount of Carotenoids
Seeds contain high content of amygdalin (vitamin
B17) (>5.5g/100g amygdalin content makes the bitter
kernal poisonous for consumption)

USES
Mainly used as table fruit
As a canned and dried fruit
Used in preparation of Jam, Jelly, Leather and Nectars
Seed is about 15% of the fruit and contains kernel
which is about 34% of the seed
Sweet kernel tastes like Almond and hence used as a
substitute for Almond
Sweet kernel is used in confectionary industries
Bitter kernel is used in oil extraction and is used in
cosmetics and pharmaceutical industries
Used for treatment of tumor and ulcers
Seed is used as an alternative treatment for cancer.

Origin and distribution
•Origin: N-E China
•Major apricot producing countries: China, USSR, Turkey,
Italy, Spain, Greece, France and USA
•Commercial cultivation of apricot in India was started by
Europeans during 1870
•Presently in India it is grown commercially in hills of HP,
J & K, Uttarakhand

Soil And Climate
It is a hardy crop
pH: 6-6.8
Deep fertile, well drained loamy soils are readily suitable
for cultivation
Grown at an altitude of 900-2000m MSL
Chilling requirement 300-900hrs, below 7°C for
fruiting
Rain fall: 100cm, well distributed through out the year
Summer temperature: 16.6-32.2°C
For flowering temperature is 5-6°C
Long cool weather and frost free areas are the best
High humidity during summer increases the Brown Rot.

Yield and storage
Yield:
Storage:
propagation
Commercially propagated by Grafting and Budding
Tongue grafting is practiced in February
T and chip budding is practiced in June-September
Raising of rootstocks:
Seeds of Apricot are the best
Wild apricot seeds are also used to raise rootstocks
Peach, Plum seeds are also used
The seeds are stratified for 45-50 days at 4°C
temperature to break dormancy.
The seeds can be stored for 5 years without losing
viability
Peach is good root stock for light and dry condition.

Yield and storage
Yield:
Storage:
Planting: One-year-old healthy grafted plants should
be planted in the field in square system.
Season: during dormant season, Dec – March
Spacing: 6×6m
HDP is less adopted because of very less availability of
dwarfing root stocks.

Training :
•Apricot trees are trained to
modified central leader system
•Open vas e and palmate types
are also followed where
mechanical harvesting is
done.
Training and pruning

Yield and storage
Yield:
Storage:
pruning
•Apricot bears fruits on previous year’s growth and short
spurs.
•The spur bearing branches die after 3-4 years.
•Therefore pruning should be done aimed to induce new
growth on such braches and to provide fruiting spurs for
the subsequent years.
• It consists of heading back(1/3rd) and thinning
out(25%) 1year old wood and has balanced vegetative
growth.
•Pruning in January-end to second week of February to
encourage production of more fruiting spurs.

Storage:
Harvesting and post harvest management
Maturity indices:
Fruit size
Color change from green to yellow
 lose flesh firmness
high TSS (10°B)
The fruits become ready for picking from first week of May – June
Manual harvesting is more practiced
For distant markets, fruits should be hand picked individually at
semi-hard stage when they develop green to amber color.
Keep them in a cool place and pack in perforated CFB boxes of 1-4
kg capacity with straw cushion.
 Care should be taken that the damaged fruits are not packed with
healthy ones.

Physiological disorders
1. Pit burn:
Occurs when the apricots are exposed to temp
above 38°C before harvest
Under such condition the flesh tissue around the
stone softens and turns brown
This is due to heat injury and it increases with
higher temperatures and longer duration of exposure
to sun
Control:
avoiding the heat injury by providing some shade
to the fruits

Yield and storage
Yield:
Storage:
2. Gel breakdown or chilling injury:
It is characterized by breakdown of tissues
It is sometimes accompanied by sponginess and gel
formation
In the initial stages there is occurrence of water
soaked areas that subsequently turn brown.
This occurs when the fruits are stored at low
temperature between 2.2-7.6°C
These have short market life and loose flavor.
