Arbuscular MycorrhizalTechnology on the horticultural

plant production at nursery

Plant propagationAsexual Methods:

Tissue cultureCuttingsLayeringGrafting

Sexual Methods:Seedlings

Objective:

To produce higher amount of plants to be marketed, incorporated in commercial production, used in landscaping, and utilized on therestoration of highly disturbed sites. Plant Quality???

How to increse plant quality in nurseries:

1. Using appropriate substrates

2. Susbtrate sterilization or disinfection

3. Fertilizer applications

4. Using pesticides

5. Cultural practices (Pruning)

6. Verifying and using healthy plant propagules

7. Utilizing beneficial microorganisms:a) Plant growth promotersb) N2-fixers (Free living and Symbiotic)c) P-solubilizersd) Mycorparasitc and antibiotic fungie) Antibiotic bacteriaf) Arburcular mycorrhizal fungig) Ectomycorrhizal fungi
