The strawberry cultivars Arosa, Clery, Miss, Raurica, Queen Elisa, Diamante and Madeleine grown in Slovenia were harvested at the commercially maturity stage and the content of total ascorbic acid and dehydroascorbic acid (DHA) was determined. Ascorbic acid (AA) was measured by using high-performance liquid chromatography and photodiode array detector. The total AA content of cultivars ranged f...

general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...

The population genetic structure of 278 Venturia inaequalis isolates, collected from different apple cultivars of eighteen different provinces in Iran, was investigated using 22 polymorphic microsatellite markers. Analysis of molecular variation, Bayesian clustering and Nei's genetic distance analyses based on 88 microsatellite alleles indicated substantial levels of gene flow among the collect...

iran is renowned as one of the olive origins in the world; therefore, characterizing and conserving the existing genotypes compared to exotic cultivars and organizing these genotypes are of critical importance. one of the most important factors in successful cultivation of olive trees is the identification and selection of suitable cultivars for each geographic region to produce oil with approp...

a split plot experiment based on randomized complete block design (rcbd) with three replications was conducted in 2012,treatments were included the time of foliar application with 3 levels (tillering stage, heading stage and no spray (control)) as main factor and cultivars in 4 levels (sardari, rijav, biseton and rashid) as the second factor. plant characteristics such as plant height, length o...

The pink hibiscus mealybug, Maconellicoccus hirsutus (Green), is a highly polyphagous pest that invaded southern Florida in 2002 and is now widely established throughout most of the state. Although Hibiscus rosa-sinensis L. is a preferred and economically important host of M. hirsutus, the susceptibility and expression of feeding symptoms by different cultivars have not been evaluated. Cultivar...
