Germination versus pure germination

Pollen Germination vs. Pollen Viability - Amphasys- Germination versus pure germination ,Figure 1 underlines the importance of the germination buffer composition and how strongly it affects the germination results. For pollen with a viability of more than 80%, germination rates of less than 20% were obtained with the standard agar germination buffer. Using an optimized germination buffer the germination rates reached similarThe Water Germination Intention Experiments - Lynne McTaggartAfter our successful Germination Intention Experiment, and the interesting results we got from our three Water Intention Experiments, psychologist Dr. Gary Schwartz, director of the Laboratory for Advances in Consciousness and Health at the University of Arizona, and I decided to merge the two by carrying out a Water Germination Experiment.

Pure Live Seed

Pure live seed (PLS) is a measure used by the seed industry to describe the percentage of a quantity of seed that will germinate. PLS is obtained by multiplying the purity percentage by the percentage of total viable seed, then dividing by 100. Purity is the percentage of seed by weight that is the labeled species; the rest of the material is inert, weed seed, or other crop seed.
