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.

are also followed where
mechanical harvesting is
done.

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.

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

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.

    Yield and storage Yield: •A5-year-old tree may provide 35 kg fresh fruits. Storage: • Fruits are highly perishable. •Fruits harvested at optimum maturity can be stored for a week at 5`C and 85 % relative humidity. 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

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.
