DEFINITIONS
Growth or grow means an increasing incident
of volume which covers the increase of the
number of cell, cell volume, kinds of cell and
substances of cell that is irreversible.
Development is a process that is parallel to
growth. Development can be defined as a
process that leads to maturation and can not be
measured.

MERISTEM TISSUES OF PLANT
Anatomy of tree
(Campbell, 1997).
Hal.: 4
1. Growing point :
It happen in root and stem ends and make plants higher and
loonger. It is called primary growth.
There are 2 theories of growing point::
a. Histogen Theory stated by Hanstein. Consist of:
- Dermatogen,
- Periblem,
- Plerom,
b. Tunika Korpus Theory stated by Schmidt. Consist of:
- Tunika,
- Korpus,
2. Vessel Cambium (between xilem dan floem). Makes plants
grow wider, it is called secondary growth.
3. Sponge Cambium (felogen) the growth goes outside to form
sponge cells (felem) instead of broken epidermis. This is to
cover surface and go inside making living feloderm of cell.
There is a cleft among sponge cells that is as a place where
the air comes in and it is called cell lenti.
4. Perisikel (perikambium) ia a tissue which functions to form
branches of root and stem.
5. Stem Parenkim

1. Gen is the carrier factors of nature that are owned by
all creatures, both plants and animals.
2. Environment around plants:
1. Temperature: plants can live well in optimum
temperature
2. Light, at green leaved plants, the light is
regnited for photosynthesis.
3. Water o r moisture is needed by plants for the
growth.
3. Growing substance (hormone) can influence the growth
of certain organs.

KINDS OF GROWING
SUBSTANCES
1. Auksin is indl asetat cmpound and its
combination, found in enlonging plant
ends. Functins of auksin:
1. Stimulating cell enlonging
2. Stimulating growing plants
3. Stimulating the forming of fruits
without pollination called
partenokarpi.
4. Bending stem
5. Stimulating lateral & fibrous root
6. Stimulating the split of vessel
cambium
7. Making differential cells xylem
8. Increasing the development of
flower and fruits.
9. Apical domination (obstructing
the growth of side shoof/ arnynt)

1. Giberelin, was found in giberella
fujikuroi (a kind of parasitic moss
in rice plant). Function of
giberelin:
1. Stimulating cambium
activities
2. Causing plants in bloom
faster
3. Enlarging fruits
4. Influencing embryo growth
5. Obstructing seed forming
6. Stimulating the forming of
pollen line and flowers.
7. Breaking seed dormant and
side bud.

1. Sitokinin
Sitokinin function to:
 Stimulate the spilt of cell
faster
 Stimulate bud growing to
the side
 Stimulate the widening of
leaf
 Reduce apical domination
 Control the forming of
flower and fruit
 Delay the falling of leaf,
flower, and fruits by
increasing food supply to
those organs.

1. Kalin functions to stimulate the growth of certain
organs. Based on organs affected, it is devided
into:
1. Kaulokalin, functions to stimulate stem growth
2. Rhizokalin, functions to stimulate root growth
3. Fitokalin, functions to stimulate leaf growth
4. Anthokalin, functions to stimulate flower growth
5. Traumalin acid, functions to stimulate “kalus”
growth of dicotil stem injured.
6. Absisat acid, functions to obstruct the growth in
bad conditions so that the plant is in dormant
condition.
