Plant scientists have been using mechanically controlled environments to make significant contributions to the science of botany, however, often haphazard and incomplete environmental measurements have made it difficult, if not impossible, to gain the full utility of this research. Concern for completeness and accuracy of these measurements has been the driving force behind an effort to establish a set of guidelines useful in conducting and reporting research in plant growth chambers.

Guidelines were developed initially by members of the USDA, North Central Re9ion Growth Chamber Use Committee (NCR-101) and were extensively critiqued, amended and expanded by the American Society of Horticultural Science (ASHS) Controlled Environments and Growth Chamber Working Group and the American Society of Agricultural Engineers (ASAE) Structures and Environment Committee (SE 303). These guidelines were then presented to over 100 participants at a 3-day Controlled Environments Working Conference (University of Wisconsin, March 1979) sponsored by the above groups and the Biotron at the University of Wisconsin. The importance of each environmental parameter and the current measurement


techniques was presented by an accomplished scientist working primarily in that research area. The proposed guidelines were next presented by a member of the NCR-101 committee and several hours of open discussion followed. Based on the detailed discussion some modifications were made and the guidelines along with the entire proceedings were published by Academic Press as "ControlledEnvironmentGuidelinesforPlantResearch" (ed. T. W. Tibbitts and T. T. Kozlowski, 1979).

These guidelines, summarized in Table 1, reflect the current thinking of many scientists, engineers and manufacturers. They provide recommendations on types of instruments to utilize for measurement, where and when measurements should be taken, and the format and units that should be utilized in reporting the environment of each study. The guidelines have incorporated Standard International units to a large extent. It is anticipated that these guidelines will be continually updated as instrumentation is improved and the need for greater environmental precision is demanded by environmental researchers. A listing of useful instruments for making measurements to meet these guidelines can be obtained by writing to the Growth Chamber Working Group, American Society for Horticultural Science, Mt. Vernon, VA, 22121.

The adoption of these guidelines by re- searches will significantly improve the quality of environmental research and greatly aid in making comparisons among studies conducted in different laboratories.


Young Botanists Recognition Awards:
Nominations for the Young Botanists Recognition Program for 1981 are requested. The program is designed to offer individual recognition to outstanding senior under-graduates in the plant sciences and to encourage their participation in the Botanical Society. Awards to successful nominees in the form of Certificates of Recognition, signed by the President of the Society, will be forwarded to the chairperson of
the candidate's department for presentation.

Nominations, with appropriate documentation, should be forwarded to Barbara Webster, Chairperson, Membership and Appraisal Committee, Department of Agronomy and Range Science, University of California, Davis, CA 95616, by May 15, 1981.

Biosis Indexes 5,000,000th Citation:
BioSciences Information Service, the publisher of BiologicalAbstracts, BiologicalAbstracts/RRM (Reports, Reviews, Meetings) and the computer-searchable form of the data base, BIOSISPreviews, has announced the indexing of its 5,000,000th life science research article since its incorporation in 1926.

In 1961, BIOSIS published its millionth abstract; reflecting the explosive growth of the life science literature, the 2,000,000 mark was reached in 1968. By the end of 1972, the 3,000,000th citation had been added to the data base, and in 1976, the golden anniversary of BIOSIS, the 4,000,000 milestone was reached.

Second Solanaceae Conference. The Second Solanaceae Conference will be held at the Missouri Botanical Garden, 3-6 August 1982. All interested in attending or submitting papers should contact me as soon as possible. Abstracts should be received before 1 April 1982.

The first Solanaceae Conference was held in Birmingham, England, in 1975 under the guidance of Prof. J. G. Hawkes and R. N. Lester. This was a highly rewarding event to those who attended, and it resulted in publication of an important volume of proceedings: The Biology and Taxonomy of the Solanaceae, eds. J. G. Hawkes, R. N. Lester and A. D. Skelding, published for the Linnaean Society of


London by Academic Press. Emphasizing the systematics of the family, sessions were held on floristics, biosystematics, cytogenetics, morphology, evolution, chemotaxonoy, generic considerations and other aspects of Solanaceae study. A series of relaxed evenings of discussion and slide shows added greatly to the interchanges of ideas and information.

The Second Solanaceae Conference will proceed along similar lines, and it is hoped a good attendance and presentation of stimulating papers will greatly further knowledge of this important plant family. Suggestions as to format and content of the Conference are eagerly requested. Contact: W. G. D’Arcy, Missouri Botanical Garden, Post Office Box 299, St. Louis, MO 63166

Geologic Factors and The Evolution Of Plants. Sponsored by the Paleobotanical Section,Botanical Society of America to be held at the Third North American Paleontological Conference, August 5,6,7, 1982, Montreal.

Contributors to the symposium will be asked to address the effects of geological factors upon the evolutionary history of plants or the reciprocal influence of plants upon geological processes. Both botanical and geological perspectives are desired, and an interdisciplinary approach is essential. Interested parties are invited to submit a title and abstract (on a form available from the secretary) of the material they intend to cover to the steering committee on or before Aug. 1, 1981. The steering committee will choose from among the submissions so as to render the final presentations of uniform content and quality. Acceptance/rejection notification will be made before the NAPC III contributed paper deadline of Sept. 15, 1981. Participants in the symposium will be invited to submit a manuscript at the time of the symposium for inclusion in a symposium volume. Please direct questions and prospective titles to Bruce H. Tiffney, Secretary, Symposium Steering Committee, Dept. of Biology, Yale University, 260 Whitney Avenue, P.O. Box 6666, New Haven, CT 06511, U.S.A.
