title: Study of chemical composition and biological activity of substance-satellite of seed of Metasequoia glyptostroboides Hu &amp; Cheng
abstract: Using scanning electron microscopy, it was found that the composition of substan­ces-satellite of seeds of Metasequoia glyptostroboides Hu et Cheng consist Carbon, Oxygen in a lot amount, which we believe indicates the organic nature of the substance, and Phosphorus, Aluminum, Chlorine and Potassium in smaller concentrations. The substance in the high (2–1%) concentrations reduced germination metasequoia seeds, but it stimulated their germination at the decreasing concentration in the range of 0
