Papers should be submitted to the respective Coordinating Committee members by 31 December 1992. The report will be published by June 1993.

Hutton (other genera) Todd C. Wehner (cucumber) J. Brent Loy (Cucurbita spp.) Timothy J. Ng, Chair Comments from CGC Gene List Committee Lists of known genes for the Cucurbitaceae have been published previously in Hortscience and in reports of the Cucurbit Genetics Cooperative. CGC is currently publishing complete lists of known genes for cucumber (Cucumis sativus), melon (Cucumis melo), watermelon (Citrullus lanatus), and Cucurbita spp. on a rotating basis. It is hoped that scientists will consult these lists as well as the rules of gene nomenclature for the Cucurbitaceae before choosing a gene name and symbol. Thus, inadvertent duplication of gene names and symbols will be prevented. The rules of gene nomenclature were adopted in order to provide guidelines for the naming and symbolizing of genes previously reported and those which will be reported in the future. Scientists are urged to contact members of the Gene List Committee regarding questions in interpreting the nomenclature rules and in naming and symbolizing new genes. Cucumber: Todd C.

Curators are responsible for collecting, maintaining and distributing upon request stocks of the known marker genes. CGC members are requested to forward samples of currently held gene stocks to the respective Curator. Cucumber: Todd C. Wehner and Jack E. Staub Melon: J.D.

GREMILLION Department of Anthropology The Ohio Stute University Columbus, OH 43210-1364 ABSTRACf.-A large body of data on several key morphological characters has been compiled through examination of collections of archaeological Chenopodium from eastern North America. Contrary to expectations based on change in certain other seed crops, the patterns of variation observed in Chenopodium do not reflect a gradual evolution of seed morphology away from the wild type. Evidence for decreasing levels of morphological variability in the evolving domesticate is like­ wise minimal. These findings demonstrate that the rate and character of crop evolution as revealed in the archaeological record can be expected to vary consid­ erably among taxa. RESUMEN.-Se ha compilado un extenso ouerpo de datos sobre varios carac­ teres morfol6gicos clave mediante el examen de colecciones de Chenopodium arqueol6gico del este de Norteamerica. Contrariamente a las expectativas basadas en el cambio en ciertos otms cultivos de semilla, los patrones de variaci6n obser­ vados en Chenopodium no reflejan una evoluci6n gradual de la morfologia de las semillas en credente distancia del tipo silvestre. La evidencia de niveles decre­ cientes de variabilidad morfol6gica en la especie domesticada en evoluci6n es asimismo minima.

CLIMATE CHANGE AND CULTURAL RESPONSE IN THE PREHISTORIC AMERICAN SOUTHWEST Larry V. Benson and Michael S. Berry ABSTRACT Comparison of regional tree-ring cutting-date distributions from the southern Col- orado Plateau and the Rio Grande region with tree-ring-based reconstructions of the Palmer Drought Severity Index (PDSI) and with the timing of archaeological stage transitions indicates that Southwestern Native American cultures were peri- odically impacted by major climatic oscillations between A.D. 860 and 1600. Site- specifi c information indicates that aggregation, abandonment, and out-migration from many archaeological regions occurred during several widespread mega- droughts, including the well-documented middle-twelfth- and late-thirteenth- century droughts. We suggest that the demographic response of southwestern Native Americans to climate variability primarily refl ects their dependence on an inordinately maize-based subsistence regimen within a region in which agricul- ture was highly sensitive to climate change.

Traditionally, there were two primary orange flesh melon types grown and sold; western types, which are fruits that range in size from about 3 to 5 pounds which are heavily netted and not sutured, and eastern types which have some netting, have a shorter shelf life but have a larger fruit size than a western melon, and tend to have a softer flesh with apparent more flavor than a western melon.

YOHE, II Archaeological Survey of Idaho Idaho State Historical Society Boise, Idaho 83702 ABSTRACT.-During archaeological test excavations in two rockshelters in Death Valley, California, two storage features were unearthed which were found to contain numerous perishable artifacts and foodstuffs. In addition to seed remains of indigenous species, including mesquite and pinon, several seeds of introduced cultigens were recovered from within the features, including melon, squash, and beans. The feature containing the greatest number of domesticate seeds appears to date to the late nineteenth and/or early twentieth century and represents the first reported archaeological evidence of Shoshoni horticulture in the southwestem Great Basin. RESUMEN.-Durante excavaciones arqueologicas preliminares en dos refugios de roc a en el Valle de la Muerte, en California, se descubrieron dos almacenamientos que resultaron contener numerosos artefactos y alimentos perecederos. Adernas de restos de semillas de especies nativas, incluyendo mezquite y pinon, se encontraron dentro de los vestigios varias sernillas de cultivos introducidos, incluyendo melon, calabaza y frijol. EIalmacenamiento que contenia el mayor ruimero de semillas domesticadas parece datar de finales del siglo diecinueve y/ 0 principios del siglo veinte, y representa la primera evidencia arqueologica reportada de horticultura shoshoni en el suroeste de la Gran Cuenca. RESUME.-Des reconnaissances archeologiques conduites dans deux abris rocheux de la Vallee de la Mort en Californie ont permis de mettre au jour deux structures d'entreposage contenant plusieurs objets et denrees perissables.

ACKNOWLEDGMENTS This dissertation could not have been completed without the support and help of many people who are gratefully acknowledged here. My greatest debt is to Dr. Daniel James Cantliffe, who has been a dedicated advisor and mentor, but mostly an excellent friend. He provided constant and efficient guidance to my academic work and research projects. This dissertation goal would not be possible without his insightful, invariable and constructive criticism. I thank Dr. Daniel J. Cantliffe for his exceptional course on Advanced Vegetable Production Techniques (HOS-5565) and the economic support for living expenses during my graduate education in UF. I extend my appreciation to my supervisory committee, Dr. Donald J. Huber, Dr. Harry J. Klee, and Dr. Donald Hopkins, for their academic guidance.

  • ABSTRACT OH, JIYOUNG. Growth Regulator Effects on Watermelon
    ABSTRACT OH, JIYOUNG. Growth regulator Effects on Watermelon Chilling Resistance, Flowering, and Fruiting. (Under the direction of Dr. Todd C. Wehner.) The watermelon [Citrullus lanatus (Thunb.) Matsum. & Nakai] is classified as a tender warm season crop and is native to the Old World tropics and subtropics (Bates and Robinson, 1995). Watermelon seedlings may be exposed to temperatures between chilling and optimal for weeks before temperatures stabilize. An experiment was conducted to determine the abscisic acid effect on the watermelon chilling resistance in nine different cultivars that examined whether they were resistant or susceptible. Eighty, 160, and 320 mg/kg ABA applied 12, 24, 36 or 72 hours before chilling provided protection from chilling damage. Hybrid watermelon seeds are produced by hand pollination using alternating rows in a field for the two parental inbred lines. In some cases, a male sterile has been used to make hybrid seed production easier. However, since the male sterile is the genic type, it is necessary to check each plant to make sure it is male sterile and must be removed before pollination begins. To avoid the labor involved in removing the male flowers, we conducted a study to identify growth regulators that would convert monoecious into gynoecious. We evaluated ten different growth regulators for their effect on staminate: pistillate flower ratio in more gynoecious and androecious watermelon cultivars. AVG (aminoethylvinylglycine) with 100 mg/kg of ethrel appears to increase the percentage of pistillate nodes. However, a single treatment of AVG without ethrel had no effect on sex expression. None of the other treatments induced higher gynoecious sex expression compared with the control.
