ALPINE PLANTS AND LOWLAND PLANTS – SCIENTIFIC EXPERIMENTSSome time ago, Professor Flueck delivered an interesting lecture to members of the Swiss Association of Apothecaries dealing with exactly these observations and the many factors that combine to produce active substances in plants. The lecture was based on the results of experiments in which various medicinal herbs had been grown at different altitudes but in identical soils. The experiments enabled Professor Flueck to prove beyond doubt that the therapeutic value of the plants does not depend solely upon the altitude at which they grow. In order to accurately identify the other factors involved, the experiments were fully controlled; the same plant was grown at different altitudes but in the same kind of soil in every case. Better growth and content of active substances was achieved with the plants grown in sheltered mountain valleys, exposed to sunshine but protected from the winds, than with those grown at higher altitudes with equal exposure to the sun but unprotected from the winds. For this reason certain plants were found to do better at middle elevations than at higher altitudes. Others produce a higher content of medicinal properties if grown in the shade, or at least semi-shade, but these are usually exceptions to the rule. *681/28/1* Related Posts:Tags: Herbal Leave OneYou must be logged in to post a comment. |
