in 2007 and 2008, the influence of pollen source on the shell and kernel traits of resulting seeds and on fruit set was examined to evaluate the potential for xenia or metaxenia in persian walnut. pistillate flowers of ‘jamal’, ‘chandler’, ‘hartley’ and ‘pedro’ were crossed with the pollen of ‘serr’, ‘z60’ and ‘damavand’. the pistillate flowers on each female parent were covered about one week ...

In this research, twenty genotypes of cucumber (Cucumis sativus) were studied that were collected from different geographical regions. The experiment was conducted as a randomized complete Block Design (RCBD) with four replications in Greenhouse. Data was collected on morphological features, yield and components of yield of cucumber which include: Total fruit yield per pickling, Fruit number pe...

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’ ...

a study of the combining ability and gene effects, that can obtained through diallel cross analysis provides considerable information to breeders for a design of breeding programs. inheritance and genetic control of yield and its components were studied in a full diallel cross for seven iranian cantaloupe cultivars namely: rish-baba, shah-abadi, samsouri, dastjerdi, magasi-neyshabour, till-toro...

this study was carried out on olive trees cv. amygdalifolia, to investigate the effect of spraying potassium nitrate, kno3, and zinc sulfate, znso4, on the fruit weight, dimension and volume. the plants were sprayed with 0, 0.5, 1.0 and 1.5% kno3 and 0, 0.25, 0.50 and 0.75% znso4 and their combinations in august about halfway through the fruit growth period. the highest fruit weight was observe...

grapevine is one of the very important fruit crops in iran the fruit of which is used as table grape and/or raisins. in this study, some genetic parameters (phenotypic and genetic correlation, heritability and repeatability), of some important traits in table grape (date of ripening, weight, length and width of berry as well as attachment to cluster strength) were evaluated. results showed high...

flowering and fruit production of ‘nagami’ kumquat is somewhat different from other citrus species because usually have three flowering peak in a year which can lead to producing fruits with different quality on a tree. considering the proper effect of paclobutrazol on raising citrus flowering, a pot experiment with three levels of paclobutrazol (zero, 0.1 and 0.5 g ai per tree) and six replica...

a study was conducted at the research station of department of horticultural science (tehran university, karaj) to evaluate the effects of water stress on yield, growth and some physiological parameters in iranian melon. the experiment was set out in a split plot design with three replicates. treatments consisted of factorial arrangement of three irrigation levels (starting irrigation at -50, -...

in this investigation some chemical and morphological properties of dog rose fruit in 10 regions of north iran were measured. results showed significant difference between traits in studied regions. beta-carotene ranged between 0.05 – 0.323 (mg/g fw). total soluble carbohydrate varied from 5.9 – 23.3%. the highest content of total anthocyanin 23.7 and the lowest was 7.71(mg/l cyanidin-3-glucosi...
