8. Utility:
Apart from being eaten raw quince are
commonly made into preserves jellies.
The fruit is called as golden apple as a
symbol of love marriage ,fertility.
The cooked fruit is an important source of
pectin for food preservation, and a fragrant
addition to jams,juices,pies,candies ,pastes,.
Quince are used in medicine preparations.
Cosmetic industry

14. climate
Quince is a Heliofilic fruit, so well lighted place suit them
best.
Quince grows well in warm cooler area.
Tree frosts at around -27ċ N .
Buds frost at -23ċ.
Roots frost at -12ċ.
if fruits are exposed to early autumn frost begins to freeze -
2.2ċ.
Quince have low chilling requirement -100 to 450 hours
below 7ċ.
Rainfall : 750-990 mm
Quince relatively well tolerated to drought periods.
Folded plastic sheets are used to reduce transpiration.

15. Wind:
Cause severe damage in High density planting.
Soil :moderate moist, porous soils rich in nutrients are
suitable.
Heavy moist soils, dry and sandy soils are not suitable..
On high calcarious soils quince is prone to Chlorosis.
Species of quince:
Cydonia oblonga var.pyriformis : fruit is pear shaped.
Cydonia oblonga var.pyramidalis : plant shape is like
pyramid

16. Cydonia oblonga pyriformis

17. Cydonia oblonga Var lusitanica :
Pear shaped fruit, leaves are large.
Cydonia oblonga Var maliforms :
Fruit is apple shape.
Cydonia oblonga Var marmorata:
Leaves are yellow or white in colour.
Cydonia oblonga maliforms

18. Varieties of quince:
Portugal :
medium,
pear shaped,
poor quality.

19. De vranja :
large long pear
shaped good quality

20. Champion:
medium,
pear shaped,
pale pink fruit.

21. Orange: early,
small medium,
pear shaped,
poor quality fruit.

22. Reas mammoth:
larger,
short pear-shaped.

23. Smyrna: long pear shaped.

24. Pine apple:
medium,
pear shaped,
good quality.

25. Masters early :
large pear shaped.

26. Missouria mammoth.
powells prize.
Fullers.
van dman .
are some of the varieties.

27. Promising rootstocks used for high density
planting are:
Quince-A:semi dwarf : ideal rootstock for bush trees.
Quince EMH : Dwarf : released from East Malling in 2002,
this is close to Q-C in size but imparts better fruit size, cropping is
not earlier.
Quince-C: dwarf and slightly earlier into cropping.

30. Propation : quince is propagated by
hard-wood cuttings, cutting should be 25 cm long taken during
winter period December-February.
Spacing : 5×2.5-3 meters,which will require some 667-800
trees per hectare.

31. Training:
quince trees are usually
developed as vase or open
centered trees.
Pruning:
if tree become too high,
the tops can be shortened

33. Controlled ground cover
helps to increase productivity, sod
culture involving mowing, similar
to that for apple, and pear
growing is beneficial.
Legumes, clovers alfa
alfa are often included in the
sod to increase fertility.
Nutrition and water management :

34. MULCHING :

35. Irrigation:
the availability of irrigation,
even in high –rain fall
districts is essential to
maximize early tree
development.
Early, heavy crops, achive
consistant cropping and
produce fruit of optimum size.
Application of sufficient
water throught the season
is necessary to maintain
steardy fruit growth.

36. Nutrition: nutritional need vary according to soil
fertility, tree age,density,productivity.
As a rule mixed fertilizers are best select one
that has nitrogen (N) content higher than that of
phosphorus (P) and potassium (K)
apply a selected mixture to give about 350g
N annually to each tree of full bearing capacity.

37. Fruit thinning : application
of
sodium 4,6 di nitro –o-
cresol DNOC at full bloom
or,
NAA at post bloom
include satisfactory thinning
in pome fruits.
Harvesting : harvesting
may commence as early as
mid February extending to
April.

38. Storage :quince can
be stored
successfully for a
period of two months
at a temperature of
0ċ-1ċ.
.

39. Packing : for fresh
market small sized of
quince can be packed
in Fibre board cartons.
Yield : young and
mature plants with
about 250 trees per
hectare will yield
about 25-35 tonsper
hectare

40. Physiological
disorder :
BROWN CORE :browning of
the flesh around the seed cavity.
Cause: it is a low temperature
storage disorder of pome fruits.
It becomes serious when fruits
are stored for long period at 310-
320F.
CONTROL : Store the fruits at
380 in controlled atmosphear to
prevent brown core.

41. Diseases of quince
Quince rust

42. Quince fire blight

43. Scab of quince

44. Blue mold of quince

45. Pest of quince:
