This conference is the 14th biennial meeting of the international cucurbit research community. The first meeting was held in Avignon France in 1988, with subsequent meetings in the United States (1990, 1994, 1998, 2002, 2006, and 2010), Poland (1992), Spain (1996), Israel (2000), the Czech Republic (2004), France (2008), and Turkey (2012). We look forward to continuing this tradition of open communication and collaboration among researchers in the cucurbit community at this meeting and the next meeting planned for Poland in 2016. Many people contributed to the planning for and organization of Cucurbitaceae 2014. We thank the staff of ANR Event Services at Michigan State University whose help was instrumental in the success of this meeting, especially the experience and organizational skills of Betsy Braid and Mary Slevin. We also thank Sylvia DeMar at the American Society of Horticultural Science for her efforts organizing and produc- ing the Proceedings of our meeting. Cucurbitaceae 2014 would not have been possible without the financial support of Michigan State University and our corporate sponsors Monsanto, Syngenta, Bejo, Hazera, HM-Clause, Rijk Zwaan, Sakata, East-West Seed, Bayer, and Magnum Seeds. Please take the opportunity to thank representatives of these companies for their generous support of our conference.

    Origin of Plant Originated from Some Had Possibly Changed Recognise Original Wild Species. Suggested a Relationship with Pr

    The possible origin of Cucumis anguria L. by A.D.J. Meeuse (National Herbarium, Pretoria) (Issued Oct. 2nd, 1958) Cucumis India Gherkin” “Bur anguria L., the “West or Gherkin”, is a cultigen known to have occurred in the West Indies in a cultivated or more or less adventitious state since before 1650 when the first accounts of this plant were published (1, 2). The occurrence of a single species of this old world genus — which is mainly African but extends through South West Asia to India — in America, combined with the fact that it is almost exclusively found in cultivation or as an escape, makes one feel suspicious about its being truly indigenous in the New World. Naudin (4) discussed the history of this plant and suggested that it introduced from West Africa whence slaves were was originally negro brought to the New World. However, he admittedly did not know any wild African species of Cucumis which resembles C. anguria sufficiently to deserve consideration as its probable ancestor. J. D. Hooker (5) also discussed the origin of the West Indian plant and was inclined to agree that it originated from some wild African ancestral form which had possibly changed so much through cultivation that it would be somewhat difficult to recognise the original wild species. He suggested a relationship with Cucumis prophetarum and “C. figarei” but he cautiously stated that these two species are perennial, whereas C. anguria is a typical annual. A. de Candolle (6) pointed out that although C. anguria was generally assumed to be a native of the Antilles, more particularly of Jamaica, two facts plead against this idea.

Light and temperature as the main environmental factors and seed storage conditions greatly affect the germination of many Cucurbitaceae species. C. prophetarum is the perennial prostrate with woody rootstocks that grow throughout the year in the arid Arabian deserts. We examined the effects of seed storage conditions and sterilization by sodium hypochlorite (NaOCL) on germination of C. prophetarum seeds. Matured, fresh and eld stored seeds were collected in March of 2016 and 2017 from a population in the United Arab Emirates. Fresh and the stored seeds (eld, freeze, and room temperature) were germinated at three temperature regimes (15/25, 20/30 and 25/35°C) in both continuous darkness and alternating 12 h light/12 h darkness. Results The fresh and freeze stored seeds had higher germination percentage than the eld and room temperature stored seeds.

Review Development of Indigenous Cucumis Technologies (ICTs) to alleviate the void created by the withdrawal of synthetic nematicides from the agro-chemical market *Trevor Mixwell, Bokang Montjane and Pietie Vermaak Department of Soil Science, Plant Production and Agricultural Sciences, University of Johannesburg, Johannesburg, South Africa. Accepted 16 July, 2015 The ”Indigenous Cucumis Technologies” (ICTs) were researched and developed for the management of plant- parasitic nematodes, particularly Meloidogyne species, in an attempt to alleviate the void created by the withdrawal of synthetic nematicides from the agro-chemical markets and the drawbacks associated with the use of conventional organic matter as a nematode management practice. Currently, ICTs comprises of four technology types, namely (1) ground leaching, (2) nematode resistance, (3) inter-generic grafting and (4) fermented crude extracts. ICTs, in their various forms, consistently suppressed the nematode numbers and improved crop yields in experimental trials carried out in Limpopo Province, Republic of South Africa. The present paper reviews a decade of successful research and development in ICTs for the management of root- knot nematodes in low-input agricultural farming systems. Key words: Cucumis species, fermented crude extract, ground leaching technology, inter-generic grafting, nematode resistance. INTRODUCTION Worldwide, the withdrawal of highly effective synthetic Been estimated at US $125 billion prior to the final fumigants used in the management of plant-parasitic withdrawal of methyl bromide from agro-chemical markets nematode populations has had economic consequences in in 2005 (Chitwood, 2003).

Morphological characterization, aDNA (ancient DNA) extraction, microsatellite analyses, and in silico sequence alignments were carried out. A total of 598 SSR fragments of 26 alleles at 12 microsatellite loci of DNAs were detected in the medieval and current watermelons. A heat map analysis using double dendrograms based on microsatellite fragment patterns revealed the closest th th similarity to current watermelons with red flesh (13 CENT) and yellow flesh (15 CENT) colors. In silico studies on cpDNA and mtDNA of watermelon revealed new data on Citrullus genome constitution. The results provide new tools to reconstruct and ‘resurrect’ extinct plants from aDNA used

Such families include; Solanaceae, Apocynaceae, Euphobiaceae and Cucubitaceae, where paddy melon (Cucumis myriocarpus) belongs. The main objective of the study was to carry out acute toxicity test of crude cucurbitacin in the ripe fruits of paddy melon (Cucumis myriocarpus) and determine its lethal dose (LD50) on laboratory rats.

Graham Centre for Agricultural Innovation, Wagga Wagga NSW 2678 2Charles Sturt University, School of Agriculture and Wine Sciences, Wagga Wagga NSW 2678 3NSW Department of Primary Industries, Wagga Wagga NSW 2650 ABSTRACT The biological attributes of two invasive weed species, prickly paddy melon and camel melon, were studied in different disturbed habitats of the Riverina region, NSW during 2010-2011. Seedlings first germinated in early to mid November 2010, once optimal soil temperatures were achieved. Flowering began in both species, generally 35 to 45 days following seedling establishment. Both species exhibited monoecious tendencies, with production of male flowers rapidly followed by production of both male and female flowers on the same vine. Both species exhibited prolific fruit production at all sites, until senescence occurred, at 150-180 days following establishment. Date of senescence varied among sites and species. Molecular genetic sequences analysis of chloroplast (MatK) and nuclear (G3pdh) genes was used to assay population genetic diversity and to verify species identity of melon species sampled from geographically diverse locations in Australia. Genetic variation within the species was not observed among the Australian populations at either of the assayed genes. This lack of genetic diversity may have resulted from a limited entry by each of the species into Australia and or sustained population bottlenecks following their entry.

Abstract Acacia trees are considered keystone species in many desert ecosystems and suffer from different anthropogenic effects. This study estimated the size structure of Acacia trees population in El-Taif area, which indicated that all the populations of Acacia present in El-Taif Area seems to be young as the proportion of small and medium individuals is greater than that of large individuals except the species Acacia albida. Absence of plant species under the canopy of Acacia trees may be due to the severe impact of grazing.
