Online classes on Plant Propagation will again be offered in January and February of 2027. Dr. Mark Bridgen, Professor of Horticulture at Cornell University, will teach these live classes via Zoom.
There are 3 modules each consisting of three 2-hour lectures. The first module is about Seed Propagation, the second module is about Vegetative Propagation, and the third module is about Plant Micropropagation. Attendees can take one, two, or all three modules. Each module is $150 or if you register for all three modules, there is a $50 discount.
Live lectures (with time for Q&A) are held on Tuesdays and Thursdays from 2 to 4pm (EST). Lectures are recorded for future reference. These recordings are helpful in case a live lecture is missed.
These are summaries of the 3 Modules and the dates that they will be offered:
Module #1 – Sexual Plant Propagation: January 12, 14 & 19
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: January 21, 26 & 28
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: February 2, 4 & 9
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).
