Chemistry of seed germination

Getting in favorable conditions, i.e. in suitable conditions of temperature and humidity, the seeds begin to germinate. In this case there goes a very intense process of breathing, and the seeds lose much weight.

Typically, young seedling, before it turned green, weighs slightly less than the seed from which it sprouted. Germinating seeds breathe more rapidly than adult plant. The latter is understandable, since during the germination of seeds occurs vigorous formation of new cells and increases the amount of protoplasm. In other words, there is an intensive conversion of substances. Stored substances pass into the protoplast substance. Taken from http://worldofschool.org

At this time, due to the enzymes, takes place vigorous transition from the insoluble form to a soluble one (starch or hemicellulose to sugars, amino acids in proteins, fats in glycerol and fatty acids). On the other hand, at this time enzymes conduct intensive synthetic activity, synthesizing individual substances included in the protoplasm. Yet in the process of seed germination processes of substances decay prevail over synthesis.

A somewhat different picture is revealed while maturing of the seeds. At this time go primarily synthesis processes and gradual dehydration of maturing seed.
