Growing Fruit & Nut Trees in the Mid Klamath Region
Growing Fruit & Nut Trees in the Mid Klamath Region by Mark DuPont Mid Klamath Watershed Council 38150 Highway 96 / PO Box 409 Orleans, CA 95556 Phone: (530) 627-3202 www.mkwc.org This work is supported by Agriculture and Food Research Initiative Food Security Grant # 2012-68004-20018 from the USDA National Institute of Food and Agriculture. Any opinions, findings, conclusions, or recommendations expressed in this publication are those of the authors and do not necessarily reflect the view of the U.S. Department of Agriculture. Growing Fruit and Nut Trees in the Mid Klamath The Mid Klamath region has excellent growing conditions for a wide variety of fruit and nut trees. The winters provide the chill necessary for many temperate zone varieties; the intense summer heat is ideal for ripening stone fruits such as peaches; the long season means we can grow sub-tropicals like figs, pomegranates and persimmons; and the wide temperature swings characteristic of our fall weather pattern are ideal for developing complex flavors in wine grapes and tree fruits. Most references address the coastal or inland climates, while this one addresses the unique characteristics of this region, with information on how to select varieties, plan an orchard and care for fruit trees.

Monofloral honey samples from three different Rhododendron species (R. ponticum L., R. luteum L., and R. caucasicum L.) were collected from the mountains of the Eastern Black Sea Region of Turkey. The experimental results revealed that each crude extract of honey and pollen exhibited significant antibacterial and antifungal capacity in the bacteria and fungus. The pollen samples and SEM images have been analysed and recorded. The total phenolic contents and antioxidative activities of the samples were investigated based on DPPH free radical scavenging activities and ferric reducing antioxidative power potentials, and higher phenolic content and antioxidant activities were observed for pollen samples with respect to honey. Furthermore, the potential to inhibit Acetyl- and Butrylcholinesterase activity and lipid peroxidation were evaluated. The potential to inhibit DNA damage were also studied, and R. ponticum honey was observed to influence most positively damaged DNA. -

Kintzel is discussed in a 1962 NNGA Nutshell article. Like Kintzel, Jenny is a vigorous tall tree with a very erect growth pattern and unusually large leaves. It does not have the orchard type growth pattern common in many Chinese chestnut trees. The nuts are large and very flavorful - one of our favorite eating nuts. Despite their size, the nuts drop early in the season. Additionally, all nuts drop within a very short period of time once the first nuts start dropping.

Aldasoro Received 13 July 2012; accepted 29 December 2014 Abstract PLANT SPECIES AND COMMUNITIES IN POYANG LAKE, THE LARGEST FRESHWATER LAKE IN CHINA.— Studying plant species richness and composition of a wetland is essential when estimating its ecological importance and ecosystem services, especially if a particular wetland is subjected to human disturbances. Poyang Lake, located in the middle reaches of Yangtze River (central China), constitutes the largest freshwater lake of the country. It harbours high biodiversity and provides important habitat for local wildlife. A dam that will maintain the water capacity in Poyang Lake is currently being planned. However, the local biodiversity and the likely effects of this dam on the biodiversity (especially on the endemic and rare plants) have not been thoroughly examined. -

Don, belonging to the Ericaceae family, is a traditional Chinese medicinal plant with a wide spectrum of pharmacological effects. This paper aimed to review the phytochemistry, pharmacology and toxicology of R. molle, and to discuss the tendency of future investigations on this plant. A systematic review of literature about R. molle was carried out using re- sources including classic books about Chinese herbal medicine, and scientific data bases including CNKI, Pubmed, SciFinder, Scopus, and Web of Science. Over 67 compounds, including diterpenes, triterpenes, flavonoids, and lignans, had been extracted and identified from R. molle. The extracts/monomers isolated from the root, flower and fruits of this plant were used as effective agents for treating pains, inflammatory diseases, hypertension, and pest, etc. In addition, diterpenes, such as rhodojaponin III, were considered as the toxic agents associated with the toxicities of this plant. These findings will be significant for the discovery of new drugs from this plant and full utilization of R.
