Common walnut (Juglans regia L) is an economically important species cultivated worldwide for its high-quality wood and nuts. It is generally accepted that after the last glaciation J. regia survived and grew in almost completely isolated stands in Asia, and that ancient humans dispersed walnuts across Asia and into new habitats via trade and cultural expansion. The history of walnut in Europe ...

In 1980-1983 small-scale tests were conducted and background information was obtalned to determine the feasibility of developing a quarantine treatment with methyl bromide (MB) for the codling moth (Cydia pomonella La) infesting in-shall walnuts. Some of the studies conducted at this time included basic dose mortality responses of diapausing and nondiapausing larvae, residue determinations and ...

Early human societies and their interactions with the natural world have been extensively explored in palaeoenvironmental studies across Central and Western Europe. Yet, despite an extensive body of scholarship, there is little consideration of the environmental impacts of proto-historic urbanisation. Typically palaeoenvironmental studies of Bronze and Iron Age societies discuss human impact in...

Aim: Many traditional treatments have been recommended in the alternative system of medicine for treatment of diabetes mellitus. Juglans regia is one of the medicinal plants used in traditional Iranian medicine as a treatment for diabetes, but little scientific documentation supports its antidiabetic action. Th e purpose of this study was to investigate antidiabetic eff ect of J. regia leaves i...

A list of species of Phaonia Robineau-Desvoidy, 1830 of Central Asia is given, and four new species of Phaonia are described from Tajikistan, Uzbekistan and Turkmenistan (P. babarabica sp. nov., P. juglans sp. nov., P. modesta sp. nov. and P. ninae sp. nov.). The male terminalia of all species and ovipositors of P. ninae sp. nov. and P. modesta sp. nov. are figured. Previous literature on the g...

The YABBY gene family is a plant transcription factor that exists in all seed plants. members have been studied extensively various plants and were to play significant roles growth development. Juglans, especially walnuts, are important economic tree species widely distributed worldwide. However, the identification related research of Juglans not reported date. In this study, we identified 19 g...

Many previous studies have shown that land use patterns are the main factors influencing soil infiltration. Thus, increasing soil infiltration and reducing runoff are crucial for soil and water conservation, especially in semi-arid environments. To explore the effects of agroforestry systems on soil infiltration and associated properties in a semi-arid area of the Loess Plateau in China, we com...

Successful invasive species often are established for a long time period before increasing exponentially in abundance. This lag phase is one of the least understood phenomena of biological invasions. Plant invasions depend on three factors: a seed source, suitable habitat and a seed disperser. The non-native walnut, Juglans regia, has been planted for centuries in Central Europe but, until rece...

The study was conducted at 10 – yearsold walnut orchard at Dr. Y. S. Parmar University of Horticulture and Forestry, Nauni-Solan(H.P.) to find out the effect of integrated nutrient management on leaf nutrient status of walnut (Juglans regia L.). There were 13 different treatment combinations of organic and inorganic fertilizers. Treatments were applied on per tree basis. Among the treatments re...

A granulosis virus was tested as a potential control agent for codling moth larvae on walnuts. The virus was produced and supplied by Sandoz, Inc. as our experimental insecticide. This virus is of considerable interest because it has little or no effect on beneficial parasites and predators and, therefore, probably would not disturb the control of the walnut aphid by the parasite Trioxys palladus.
