Module #1 – Sexual Plant Propagation: January 22, 29 & February 5
- Description: Introduction to plant propagation, biology of plant propagation, terminology,
and the propagation environment including microclimatic conditions (relative humidity,
temperature, light, & gases), edaphic factors (propagation media, nutrients, and water), and
biotic factors. Also, basics of seed propagation and seed dormancy including exogenous
dormancy, physical dormancy, seed scarification, chemical dormancy, endogenous dormancy,
physiological dormancy, seed stratification, morphological dormancy, and double dormancy.
Module #2 – Vegetative/Asexual Plant Propagation: February 12, 19 & 26
- Description: Introduction to vegetative propagation, terminology, rooting hormones, cutting
propagation, management of stock plants, treatment of cuttings, environmental manipulations
of cuttings, propagation media, stem cuttings, (hardwood, semi-hardwood, softwood,
herbaceous), grafting (types of grafts), propagation by specialized stems & roots (bulbs,
corms, tubers, tuberous roots, rhizomes, etc.), layering, division, and separation.
Module #3 – Plant Micropropagation: March 5, 12 & 19
- Description: What is plant tissue culture, uses of plant tissue culture, what is plant
micropropagation, history of micropropagation, media components and preparation,
laboratory supplies, equipment and design, stages of micropropagation: Stage 0 (stock plant
selection and preparation), Stage 1 (initiation & establishment in vitro), Stage 2
(multiplication), Stage 3 (in vitro rooting and conditioning), and Stage 4 (acclimating &
hardening off).
