The concept of planting trees in widely spaced rows and growing cash crops in the alleyways is a special form of agroforestry called alley cropping. To be successful, the companion crop’s physiological requirements (i.e., light, water and nutrients) must be accommodated by the tree. Black walnut’s (Juglans nigra L.) foliage and root system are unique and readily adapted to the growth of compani...

Description: Three experiments were conducted to investigate the effect of paclobutrazol on shoot and cambial growth of nine tree species located in Indiana and Louisiana, U.S. In Experiment I, white oak (Quercus alba L.) and red oak (Q. rubra L.) in Indiana were treated in April 1995 with paclobutrazol using the soil drench method. In Experiment II, paclobutrazol was applied in April 1996, usi...

for the successful tree establishment, an evaluation of land suitability is necessary.in this paper, we demonstrate how to implement fuzzy classification of land suitability in agis environment for afforestation with juglans regia in gharnaveh watershed of golestanprovince in iran. juglans regia is one of the most important agro-forestry species in manyrural parts of iran. relevant criteria for...

The objectives of the study were to identify the relevant hydraulic parameters associated with stomatal regulation during water stress and to test the hypothesis of a stomatal control of xylem embolism in walnut (Juglans regia x nigra) trees. The hydraulic characteristics of the sap pathway were experimentally altered with different methods to alter plant transpiration (Eplant) and stomatal con...

Here, we report the complete genome sequence of Xanthomonas arboricola pv. juglandis DW3F3, a strong pathogenic strain isolated from blighted walnut immature fruit (Juglans regia L. cv. Qingxiang). The genome consists of a single chromosome (5,144 kb).

Chandler walnut (Juglans regia cv Chandler) on Northern California Black (Juglans hindsii) and Paradox (Juglans hindsii x Juglans regia) rootstocks were irrigated to achieve two levels of regulated deficit irrigation (RDI) in 2002 thru 2005. The RDI strategy was to maintain high midday stem water potential (MSWP) early in the growing season to favor shoot growth and nut size then gradually decr...

The black walnut, Junglas nigra, is indigenous to eastern North America, and abscission of its fruit occurs around October. The fruit consists of a husk, a hard shell, and kernel. The husk is commonly discarded in processing, though it contains phenolic compounds that exhibit antioxidant and antimicrobial properties. For this study, black walnut husks were extracted using supercritical carbon d...
