in order to study the effects of different salinity levels on turnip (brassica rapa l.), an investigation was conducted at yasouj university, iran, in 2010. the effects of four salinity levels including 1.92, 9.87, 19.6 and 21.94 ds m-1 (20:1 ratio of nacl: cacl2 in hoagland solution) on germination, vegetative and maturity stages of turnip (baherghan landrace) were investigated. the results re...

the objective of this research was to discriminate four local breeds of goat in central java-indonesia using multivariate analysis. data from eight morphological traits of four goat breeds, namely kejobong goat (jg), etawa grade goat (egg), kacang goat (kg) and jawarandu goat (rg) originated from purbalingga, purworejo, grobogan and pemalang regencies, respectively, were used. one hundred and s...

identifying and selecting superior genotypes in native germplasm is one method for breeding fruit trees. five different ecotypes of jujube (ziziphus jujuba mill.) were collected from different regions of isfahan province, iran, for evaluation of their morphological and pomological traits during 2011-13. results showed that quantitative traits were more significant within ecotypes. ‘‘najafabad’ ...

in most semiarid and arid areas, fresh water shortage compels managers to use low quality water sources with high salinity to irrigate turf and landscape. recent research has noticed that management of nitrogen fertilization can alleviate salinity effects on plants. this greenhouse sand culture experiment was conducted in order to investigate morphological and physiological responses to salinit...

botrytis cinerea is an important pathogen that causes diseases in ornamental crops. in presentresearch several greenhouses of roses located in central region of iran were surveyed toidentify the botrytis cinerea. a total of 80 isolates were collected from rose greenhouses incentral region of iran. morphological identification was based on characters such asconidiophore and conidial length. acco...

six belonolaim species were collected from grasslands of sabalan region. the found species belong to genera amplimerlinius, merlinius, nagelus, neodolichorhynchus, paramerlinius and tylenchorhynchus. among the found species, neodolichorhynchus judithae is reported for the first time from iran and is characterized byhaving offset head, cuticule with 16 longitudinal ridges, delicate stylet 21-23 ...

identification and evaluation of indigenous genotypes of fruit trees are matter of consideration at the first step of the breeding programs. in order to study genetic diversity and to identify promising genotypes, 14 different genotypes of walnut in minoodasht region in golestan province (north of iran) were evaluated. traits such as nut shape, kernel color, ease of removal of kernel halves, ke...

the first step in walnut breeding programs is to identify and evaluate superior genotypes of fruit trees. hence, there are various walnut breeding programs in various areas of iran. a study aimed to evaluate the morphological and chemical characteristics of selected superior genotypes of walnut was conducted in the shahroud region in 2011-2012.  the following genotypes were selected in this stu...
