Vegetable Physiology

The vegetable physiology , or phytobiology , is the Science which studies the operation of the Organe S and the vegetable fabrics and seeks to specify the nature of the mechanisms to which the bodies fulfill their functions. She all in all seeks to bore the secrecies of the Vie at the Plante S.

The fields of study of vegetable physiology are very diversified and concern in particular:

the nutrition, in particular the absorption of the mineral elements and functions of synthesis;
the breathing and the exchanges Gas them at the plants;
the perspiration is affected by the heat and a circulation of dry and hot air, therefore loss of H₂O at the plants;
the Relations of the plants with their environment;
the growth and the development;
the vegetative or sexuée reproduction , .

History

In 1627, Sir Francis Bacon published one of the first experiment of vegetable physiology in a book named Sylva Sylvarum. Bacon successful to make grow some terrestrial plants, like pink S, in water and concludes that the ground was necessary only to maintain the plants set up. Jan Baptist van Helmont published in 1648, the first quantitative experiment of vegetable physiology, in which he explained to have made push a Saule in a pot containing a quantity of dry ground of 200 pounds and that this quantity of dry ground had decreased in 5 years only two 2 ounces. Van Helmont concludes that the plants consist of elements coming from water and not from the ground. In 1699, John Woodward published experiments of growth of mint in different types of water. It observed that the plants developed better in water added with ground that in distilled water. Stephen Hales is regarded as the father of vegetable physiology thanks to many experiments which it published in 1727. Julius von Sachs unified different the disciplines from vegetable physiology and wrote in 1868 Lehrbuch der Botanik
