Effects of Regulated Deficit Irrigation on Walnut (Juglans regia) Grafted on Northern California Black (Juglans hindsii) or Paradox Rootstock
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...
متن کاملDevelopment and characterization of new microsatellites for walnut (Juglans regia).
The expressed sequence tag (EST) database represents a potentially valuable resource for the development of simple sequence repeat (SSR) markers for use in evolutionary studies. EST-SSRs reveal polymorphisms not only within the source taxon, but in related taxa as well. In this paper, we describe a case study in which the publicly available walnut (Juglans regia) EST database was used to develo...
متن کاملLipid analysis of Greek walnut oil (Juglans regia L.).
The walnut oil (Juglans regia L.) total lipids (TL) were extracted by the Bligh-Dyer method and the lipid classes have been isolated by chromatographic techniques and they were analyzed by high performance thin layer chromatography (HPTLC)/FID and GC-MS. The oil was found to be rich in neutral lipids (96.9% of total lipids) and low in polar lipids (3.1% of total lipids). The neutral lipid fract...
متن کاملDetection and Implication of Early Agrobacterium tumefaciens Infection of Paradox Seeds and Seedlings
Paradox (Juglans hindsii × J. regia), the dominant rootstock used in California, USA walnut production, has many desirable horticultural characteristics, but is highly susceptible to crown gall. Crown gall, caused by the bacterium Agrobacterium tumefaciens, is not consistently controlled with soil fumigation. This observation, in conjunction with observations of galls occurring in above ground ...
متن کاملNanosilver Particle Production Using Juglans Regia L. (Walnut) Leaf Extract
BACKGROUND The production of nanoparticles using a biosystem is considered green chemistry. Application of plant extracts as a biological process has been proven to be suitable for synthesis of nanoparticles. OBJECTIVES This study designed in order to evaluate the production of silver nanoparticles using Juglans regia leaf extract and to compare the outcome of different preparation methods of...
