in this research, the bud and cane winter cold tolerance of 22 field-grown grapevine cultivars of kourdestan province agricultural and natural resources research and education center was evaluated at jan. and mar. stages in 2012. in these cultivars soluble carbohydrates and water content changes of buds and canes during dormant period also were measured. after exposure to different freezing tem...

Lexicographic derivatives developed by Nesterov and directed subdifferentials developed by Baier, Farkhi, and Roshchina are both essentially nonconvex generalized derivatives for nonsmooth nonconvex functions and satisfy strict calculus rules and mean-value theorems. This article aims to clarify the relationship between the two generalized derivatives. In particular, for scalar-valued functions...

This study is to determine how bilingualism could influence the list of Persian basic color terms and their order. Using a monolingual Persian and a bilingual Kurd sample students, and a color list task, it is assumed that bilingualism could change the ordering of the non-basic color terms in the second language, but not the basic ones. Another assumption is that, the old usual methods for obta...

study of morphological traits of red fleshed apples is a critical step to improve the quality andcommercializing of them. in order to study genetic diversity of iranian red fleshed apples, a total of 17morphological characteristics were assessed for eight genotypes of red- fleshed (‘haji qermez’, ‘goushtqermez’, ‘shahroud-10’, ‘arous gousht qermz’, ‘b.9’, ‘qazvin 1, 2, 3’) and 12 iranian and fo...

selection and use of tolerant grapevine as rootstock or own-rooted vines and finding indexes for screening of resistant genotypes have especial importance. to identify the salt tolerant grapevine genotypes, effects of nacl concentrations (0, 50, 100 and 150 mm) on root length, root and shoot dry weight, prolin, total soluble solid, rwc, level of salt injury, leaf concentration of k, na, cl and ...

seedlessness is the most important trait in table grape and raisin industry which has attracted breeders from long ago. breeding grapes by traditional methods result in low number of seedless progenies and their selection requires long time. therefore, marker-assisted selection (mas) can overcome the selection difficulty and would decrease high cost of progeny maintenance for several years. in ...
