Phytotron
A phytotron is an enclosed research greenhouse used for studying interactions between plants and the environment. It was a product of the disciplines of plant physiology and botany. Overview Phytotrons unified and extended earlier piecemeal efforts to claim total control of the whole environment. In both walk-in rooms and smaller reach-in cabinets, phytotrons produced and reproduced whole complex climates of many variables. In the first phytotrons each individual room was held at a constant unique temperature. The Australian phytotron, for example, had rooms maintaining 9°C, 12°C, 16°C, 20°C, 23°C, 26°C, 30°C, 34°C. Because some of the earliest controlled environment experiments showed that plants reacted differently in daytime temperatures and nighttime temperatures, the first experiments to observe the effect(s) of varying the daytime versus the nighttime temperature saw experimenters move their plants from higher to lower temperatures over the course of a daily, or any o ...

Frits Warmolt Went
Frits Warmolt Went (May 18, 1903 – May 1, 1990) was a Dutch biologist whose 1928 experiment demonstrated the existence of auxin in plants. Went's father was the prominent Dutch botanist F.A.F.C. Went. After graduating from the University of Utrecht, Holland in 1927 with a dissertation on the effects of the plant hormone auxin, Went then worked as a plant pathologist in the research labs of the Royal Botanical Garden in Buitenzorg, Dutch East Indies (now Bogor, Indonesia) from 1927 to 1933. He then took a position at Caltech in Pasadena, California, first researching plant hormones. His interest gradually shifted to environmental influences on plant growth. At Caltech he was among the first to demonstrate the importance of hormones in plant growth and development. He played an important role in the development of synthetic plant hormones, which then became the basis of much of the agricultural chemical industry. Frees is known for the Cholodny–Went model, named after Went ...

Climatron
The Climatron is a greenhouse enclosed in a geodesic dome that is part of the Missouri Botanical Garden in St. Louis. Initiated by then Garden director Frits W. Went, the dome is the world's first completely air-conditioned greenhouse and the first geodesic dome to be enclosed in rigid Plexiglass (Perspex) panels. Completed in 1960, it was designed by T. C. Howard, of Synergetics, Inc., Raleigh, North Carolina. The broad climatic range within the dome, which recreates a lowland rain forest, is achieved by sophisticated climate controls without using interior partitions. The structure is an unpartitioned half-sphere dome, 42 m in diameter and 21 m high. The frame is supported by aluminum tubes under compression and aluminum rods under tension. The St. Louis architects Murphy and Mackey were the architects on record. Synergetics, Inc were the designers of the dome. The architects received the 1961 R. S. Reynolds Memorial Award of $25,000 for their architectural use of aluminum. ...

Biotron (Wisconsin)
The Biotron is a research facility located at the University of Wisconsin-Madison that "provides controlled environments and climate-controlled greenhouses to support plant, animal, and materials research for university, non-profit, and commercial clients." History An evolution of the phytotron, the development of the facility had its roots in the late 1950s as a campaign established by the Botanical Society of America in search of a national phytotron. With additional funding and support by the National Science Foundation the Biotron was eventually envisioned as a combination facility that would allow both plant and animal tests to be conducted. Plant physiologist Folke Skoog would be instrumental in bringing the Biotron to the University of Wisconsin-Madison. A colleague of Frits Went at Caltech, Skoog oversaw the two proposals the university submitted to the Botanical Society in 1959. The interdisciplinary nature and scope of the project quickly led it to becoming Madison's mo ...

Greenhouse
A greenhouse (also called a glasshouse, or, if with sufficient heating, a hothouse) is a structure with walls and roof made chiefly of Transparent ceramics, transparent material, such as glass, in which plants requiring regulated climatic conditions are grown.These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame. The interior of a greenhouse exposed to sunlight becomes significantly warmer than the external temperature, protecting its contents in cold weather. Many commercial glass greenhouses or hothouses are high tech production facilities for vegetables, flowers or fruits. The glass greenhouses are filled with equipment including screening installations, heating, cooling, and lighting, and may be controlled by a computer to optimize conditions for plant growth. Different techniques are then used to manage growing conditions, including air temperature, relative humidity and vapour-pressure deficit, in ord ...

University Of Wisconsin-Madison
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university i ...

Ecotron
An Ecotron is an experimental instrument in ecology consisting of a controlled environment which makes it possible to simultaneously condition the environment of natural, simplified, or completely artificial ecosystems and measure the processes generated by living beings present in these ecosystems, in particular the flow of matter and energy. Design Its principle is to confine ecosystems in totally or partially waterproof enclosures which are permeable to energy flow and capable of generating a range of physical and chemical conditions applied to terrestrial or aquatic ecosystems, continental or marine. Environmental control and real-time measurements are precise enough to test hypotheses or operating models. For this purpose, the enclosures are fitted with significant equipment allowing continuous measurement of fluxes, states or biological characteristics. Other specific measurements, in situ and ex situ, on samples taken complete these online measurements. A sufficient number ...
