In this lab be will start several plant materials from seed which will be used during the course of the semester in different lab exercises. A seed is a complex structure containing an embryo, variable amounts of food reserves, and a protective outer coat.
Seed dormancy occurs during unfavorable periods for growth and development.
Seed germination requires some trigger to overcome dormancy, so that growth and further development of the embryo can resume. Sand, vermiculite and perlite have a very low nutrient composition, so nutrients must be added to pots regularly. Potting soil is easiest to use if you moisten it before planting. Fill moistened potting soil to within 2-3 cm of the top of the pot or flat. Water the soil until it is thoroughly moistened.
