due to the complex assessment of young walnut cultivars (juglansregia l.) based on morphological traits, advance molecular tools have provided a new prospect for cultivar identification and dna fingerprinting. in this study, specific molecular keys were identified for 5 iranian walnut cultivars (juglansregia l.) using 30 ssr markers. the results showed that 5 ssr markers produced polymorphic ba...

light, amber and dark colored kernels were rated by eye on a scale of 3 different genotypes (zh1, zh2 and zh3). the oil content was measured using the soxhlet extraction method, ranged from 57.26 to 68.29%, for zh1 (light) and zh2 (amber) respectively. fatty acid compositions were measured using gas chromatography. the main fatty acids were linoleic, oleic and linolenic acids, respectively. als...

For at least the past decade, an unusual decline of black walnut (Juglans nigra) has been observed in several western states. Initial symptoms involve a yellowing and thinning of the upper crown, which progresses to include death of progressively larger branches (Figure 1). During the final stages large areas of foliage may rapidly wilt. Trees often are killed within three years after initial s...

A sensitive qualitative detection method for walnut (Juglans regia) using polymerase chain reaction (PCR) was developed. For detection of walnuts with high specificity, the primer pair WAL-F/WAL-R was designed based on walnut matK genes. Trace amounts of walnuts in commercial food products can be qualitatively detected using this method.

Agrobacterium tumefaciens biovar 1 strain 186 was isolated from a walnut tree expressing crown gall symptoms. The draft genome sequence of this strain harbored genes for crown gall formation and will be useful for understanding its virulence on Paradox, the predominant hybrid rootstock used for the cultivation of English walnut in California.

This study was performed to optimize and validate Rancimat (Metrohm Ltd., Herisau, Switzerland) operational parameters including temperature, air-flow, sample weight minimize Induction-Time (IT) IT-Coefficient-of-Variation (CV), using Response Surface Methodology (RSM). According a Box–Behnken experimental design, walnut oil equivalent 3-, 6-, or 9-g added each reaction vessel heated 100, 110, ...
