PLANT PROPAGATION(AN OVERVIEW)


PLANT PROPAGATION

- conventional

- tissue culture


1. Cuttings (leaf, stem, root)

2. Layering (stem)

3. Marcotting

4. Grafting

5. Seed

CONVENTIONAL PROPAGATION


1. Micropropagation

2. Somatic embryogenesis

3. Suspension cell Culture

4. Protoplast fusion

5. Micrografting

6. Polyploidisation

7. Haploid Cell Culture

8. Mutation Breeding

9. Artificial Seeds

Key factors


• Appropriate size of each section• Media Prep & Washing• Autoclave & Media room• Transfer Room• Growth Rooms

• Work Flow (Layout) • From non-clean to clean

• Utilities & Specification• Clean water • Reliable power supply• Floor & Wall finish• Equipment layout

Plantlets ready fornext sub-culture

Culture procedures


• Continuous production • Multiplication cycle - numbers• Rooting Stages - numbers• Ready for Sale (ex-lab) - numbers

• Allocation of resources• Equipment• Manpower• Raw material

• Stock keeping (database)• Production record & estimation• Plan production to meet targets (demand)• Tracking & able to trace stock

Scheduling & stock keeping


• Production estimations• Input requirement & cost

• Raw material• Labour

• Production efficiency• Cost estimations

• Budget estimation• Business plan• Cash flow (P&L)

• Marketing• Delivery schedule

Calculations


• Smooth running of production line• Skilled & semi-skilled• Strict job specification

• Production Manager• Production Supervisor• Operators• Support staff

• Monitor & evaluate performance• Healthy and safe workplace

Human resource


Planning production

Y = No. of plantlets producedA = No. of shoots produced at each subcultureB = No. of initial explants availablen = No. of subculture passages

F1 = Proportion of usable shoots after Stage IIF2 = Proportion of usable shoots after Stage IIIF3 = Proportion of usable shoots after Stage IV

Y = An x B x F1 x F2 x F3

at a brief


Genetic resources

Forests are the main home of Earth's species. While covering only 6% of the planet's land surface, tropical forests contain at least 50%, possibly 70% and conceivably 90% of all species.

½ km2 of Malaysia's forests can feature as many tree and shrub species as the whole of the United States and Canada, while a single bush in Peruvian Amazonia has revealed as many ant species as in the British Isles.

Norman Myers


• Growing more crops and trees per acre leaves more land for Nature

• We cannot choose between malnourished children & saving endangered wild species

• Without higher yields, peasant farmers will destroy the wildlands and species to keep their children from starving

• Sustainably higher yields of crops and trees are the only visible way to safe both

Genetic modification


1. Look for the gene (s) &

remove it

2. Clone it & place it in the

desired plant

3. Ensure it functions well & does

not disrupt other functions

4. Produce many copies of the

plant
