Plant physiology
For the scientific journal of the same name see Plant Physiology (journal).In
botany,
plant physiology is the study of the function, or
physiology, of
plants. Fundamental processes such as
photosynthesis,
respiration,
plant nutrition,
plant hormone functions,
tropisms,
nastic movements,
photoperiodism,
photomorphogenesis,
circadian rhythms, environmental stress physiology, seed
germination,
dormancy and
stomata function and
transpiration, both part of plant water relations, are studied by plant physiologists.It is closely related to
biochemistry and
molecular biology.
One of the leading journals in the field is
Plant Physiology, started in 1926. All its back issues are available online for free.[
1] Many other journals often carry plant physiology articles, including
Physiologia Plantarum,
Journal of Experimental Botany,
American Journal of Botany,
Annals of Botany,
Journal of Plant Nutrition and
Proceedings of the National Academy of Sciences.Sir
Francis Bacon published one of the first plant physiology experiments in 1627 in the book,
Sylva Sylvarum. Bacon grew several terrestrial plants, including a rose, in water and concluded that soil was only needed to keep the plant upright.
Jan Baptist van Helmont published what is considered the first quantitative experiment in plant physiology in 1648. He grew a willow tree for five years in a pot containing 200 pounds of oven-dry soil. The soil lost just two ounces of dry weight and van Helmont concluded that plants get all their weight from water, not soil. In 1699,
John Woodward published experiments on growth of
spearmint in different sources of water. He found that plants grew much better in water with soil added than in distilled water.
Stephen Hales is considered the Father of Plant Physiology for the many experiments in the 1727 book,
[Vegetable Staticks [2]].
Julius von Sachs unified the pieces of plant physiology and put them together as a discipline. His
Lehrbuch der Botanik was the bible of its time.
