CHESTNUT (CASTANEA Spp.) CULTIVAR EVALUATION for COMMERCIAL CHESTNUT PRODUCTION
CHESTNUT (CASTANEA spp.) CULTIVAR EVALUATION FOR COMMERCIAL CHESTNUT PRODUCTION IN HAMILTON COUNTY, TENNESSEE By Ana Maria Metaxas Approved: James Hill Craddock Jennifer Boyd Professor of Biological Sciences Assistant Professor of Biological and Environmental Sciences (Director of Thesis) (Committee Member) Gregory Reighard Jeffery Elwell Professor of Horticulture Dean, College of Arts and Sciences (Committee Member) A. Jerald Ainsworth Dean of the Graduate School CHESTNUT (CASTANEA spp.) CULTIVAR EVALUATION FOR COMMERCIAL CHESTNUT PRODUCTION IN HAMILTON COUNTY, TENNESSEE by Ana Maria Metaxas A Thesis Submitted to the Faculty of the University of Tennessee at Chattanooga in Partial Fulfillment of the Requirements for the Degree of Master of Science in Environmental Science May 2013 ii ABSTRACT Chestnut cultivars were evaluated for their commercial applicability under the environmental conditions in Hamilton County, TN at 35°13ꞌ 45ꞌꞌ N 85° 00ꞌ 03.97ꞌꞌ W elevation 230 meters. In 2003 and 2004, 534 trees were planted, representing 64 different cultivars, varieties, and species. Twenty trees from each of 20 different cultivars were planted as five-tree plots in a randomized complete block design in four blocks of 100 trees each, amounting to 400 trees. The remaining 44 chestnut cultivars, varieties, and species served as a germplasm collection. These were planted in guard rows surrounding the four blocks in completely randomized, single-tree plots. In the analysis, we investigated our collection predominantly with the aim to: 1) discover the degree of acclimation of grower- recommended cultivars to southeastern Tennessee climatic conditions and 2) ascertain the cultivars’ ability to survive in the area with Cryphonectria parasitica and other chestnut diseases and pests present. -
An Abstract of the Thesis Of
AN ABSTRACT OF THE THESIS OF Annie M. Chozinski for the degree of Master of Science in Horticulture presented on November 23. 1994. Title: The Evaluation of Cold Hardiness in Corvlus. Abstract approved: Shawn A. Mehlenbacher Anthesis of both staminate and pistillate flowers of Cory/us occurs in midwinter. To insure adequate pollination and nut set, these flowers must attain a sufficient hardiness level to withstand low temperatures. This study estimated cold hardiness of Cory/us cultivars and species using laboratory freezing of shoots without artificial hardening. In December, January and February of 1991-92 and 1992-93, one-year stems were collected 0 0 and frozen at regular intervals from -10 C to -38 C/ and visual browning assessed survival approximately 10 days after freezing. Elongated catkins were clipped prior to freezing. Percent flower bud survival was calculated and plotted against temperature. Linear regression generated an equation relating percent bud survival to temperature. From this equation, estimates of the LT^ (lethal temperature for 50% of the buds) was calculated for catkins, female inflorescences, and vegetative buds. C. avellana L. catkins, on average, were less hardy in both December and January than female inflorescences and vegetative buds. Maximum hardiness was reached in December and nearly all had elongated prior to the February freeze. Cultivars with the most hardy catkins were 'Morell', 'Brixnut', 'Creswell', 'Gem', 'Giresun OSU 54.080', 'Hall's Giant', 'Riccia di Talanico', 'Montebello' and 'Rode Zeller'. Maximum hardiness was observed for both vegetative and pistillate buds in January and was followed by a marked loss of hardiness in February. -

Nematodes and Fungi) Against Curculio Nucum (Coleoptera: Curculionidae)
saqarTvelos mecnierebaTa erovnuli akademiis moambe, t. 15, #2, 2021 BULLETIN OF THE GEORGIAN NATIONAL ACADEMY OF SCIENCES, vol. 15, no. 2, 2021 Parasitology The Effectivenes of Entomopathogenic Microorganizsms (Nematodes and Fungi) Against Curculio nucum (Coleoptera: Curculionidae) Oleg Gorgadze*, Madona Kuchava*, Manana Lortkipanidze*, Nana Gratiashvili*, Medea Burjanadze** *Institute of Zoology, Ilia State University, Tbilisi, Georgia **Vasil Gulisashvili Forest Institute, Agricultural University of Georgia, Tbilisi (Presented by Academy Member Irakli Eliava) The nut weevil (NW), Curculio nucum, is one of the main pests of hazelnuts which damages nut buds, leaves and especially fruits. Sometimes it destroys 80-90 percent of the crop. The study presents the results of using entomopathogenic microorganisms (nematodes and fungi) against NW. Local entomopathogenic nematodes (EPN) Steinernema borjomiense, S. thesami, Heterorhabditis sp. and Boverin's fungi were used against this pest. The tests were carried out in laboratory and field conditions. Nematodes of this species were first used against NW. The tests were carried out separately and together with different doses of nematode concentracions (100, 50 and 25 IJs/insect) and Boverin – (2 g/L and 4 g/L). Among the nematodes used separately against insect pests, S. borjomiense and Heterorhabditis sp. (in a dose of 100 IJs/insect) showed the greatest effect (100%). As for the separate application of Boverin, it turned out to be less effective (42.5% of adults and 43.2% of larvae died). On insect pests, a much greater effect was observed when using combined preparations of nematodes and fungi in laboratory and field trials. In the laboratory, after the use of combined preparations, 100% death of harmful insects is recorded. -

Fungal entomopathogens provide an attractive alternative to synthetic insecticides for weevil control because they pose a lesser risk to human health and the environment. This review summarises the available data on the performance of these entomopathogens when used against weevils in horticultural crops. We integrate these data with information on weevil biology, grouping species based on how their developmental stages utilise habitats in or on their hostplants, or in the soil. -
