STUDY OF PROPAGATION PROTOCOLS OF VETIVER
Introduction
Thousands of kilometers of riverbanks, dykes was
threatened by erosion at the MK
Rapid multiplication of the grass needs to be
studied
2
Goals
Find out the rapid multiplication to supply for
the practical requirements of the MK
Which methods are available in the MK conditions
with satisfiable standards High
multiplication rate Low cost-price
3
Sexual propagation seeds?
4
Flower structure
5
Flower structure (Cont.)
6
Germination of seeds?
7
Sexual propagation seeds?
Conclusion
From the investigations, ecotype (V. zizanioides)
Vetiver induces flowers
Seeds without germination and endosperm
The ecotype can not become a serious weed
8
Unsexual propagation
There are mainly two forms
1/ Propagation by stem 3 kind materials for
reproduction Advantages simple good
results Disadvantages low multiplication rate
numerous material
2/ Micropropagation with lateral buds
Advantages high multiplication rate
Disadvantages high cost-price For low cost
production, we used the nethouse conditions
(6,0008,000 lux, 3031oC) being instead of the
growth chamber (2.000 lux, 24oC, 12 h/day)

Unsexual propagation (cont.)
1/ Propagation by stem

Unsexual propagation (cont.)2/ Micropropagation

Unsexual propagation (cont.)
Results of micropropagated plantlet production
High multiplication rate (hypothetically 58
millions of plantlet/year
Proliferation stage (modified 2 mg BA/liter)
carrying out in the nethouse will be reduce 13
production cost of each plantlets
The protocol has been applied in the MK during
the last time
12
General conclusions
Vetiver can not propagate by seed, so the grass
does not become a serious weed
Stem propagation has good results
Proliferation and rooting stage can be carried
out in the nethouse conditions. The cost
production of plantlets reduces 13. The protocol
will be transferred to local agencies
