Removing the green husk and drying walnut are one of the most important steps in post-harvest processing of walnut. Therefore, it is need to precisely identify a walnut’s shell. Physical and mechanical properties of shell in the four Persian walnut cultivars/genotypes were studied. This study investigated the mechanical properties of a walnut’s husk and calculated the required energy in the pro...

vegetative propagation of persian walnut encounters a major problem in iran growing conditions. this experiment was carried out to study the physiological effects of rootstock as regards herbaceousness or woodiness, and with respect to the presence of leaf on it or not on minigrafting success. throughout the study, 1.5-2.5 cm length persian walnut scions were minigrafted on herbaceous vs. softw...

somatic embryos of persian walnut were transformed with two strains of agrobacterium tumefaciens i.e. lba4404 and c58, and two plasmids, namely, pbi121 with nptii and gus genes for improving the transformation protocol, and p6u-ubi-fvti plasmid containing the hpt and fld genes. the transformation frequency was 10%. pcr and rt-pcr analysis proved the presence and expression of the genes. the tra...

OBJECTIVE To evaluate the effect of the intake of whole walnuts and walnut fractions on the oxidant status in mice. METHODS Thirty-six C57BL/6J male mice were randomized to be fed one of three diets: 1) a standard diet (control group), 2) a standard diet with 10% of whole walnuts (walnut-diet group), or 3) a standard diet with 2% of walnut skins (walnut-skin-diet group) for 8 wk. The plasma a...

the persian walnut (juglans regia l.) is one of the most important horticultural crops grown in iran. this research was conducted to determine the variation in walnut germplasm grown in the arak region of iran during the 2007-2008 growing seasons. all of the selected genotypes originated from seed, and their phenological and pomological characteristics were evaluated. results indicated that the...

SCOPE English walnut (Juglans regia) belongs to the most important allergenic tree nuts. Co-sensitization with birch (Betula verrucosa) pollen has been reported. We aimed to identify a walnut allergen homologous to the major birch pollen allergen Bet v 1. METHODS AND RESULTS A cDNA encoding a Bet v 1-homologous allergen (Jug r 5) in walnut kernels was cloned by RT-PCR. Jug r 5 was expressed i...
