we prove that the class of profinite groups $g$ that have a factorization $g=ab$‎ ‎with $a$ and $b$ abelian closed subgroups‎, ‎is closed under taking inverse limits‎ ‎of surjective inverse systems‎. ‎this is a generalization of a recent result by k. h. hofmann and f. g. russo‎. ‎as an application we reprove their generalization of iwasawa's structure theorem for‎ ‎quasihamiltonian pro-$p$...

for a comparison and grouping of 72 almond cultivars and genotypes, 30 traits including; 12 phenological and vegetative characters plus 18 traits related to nut and kernel were assessed, according to almond universal descriptor. the results revealed that some such traits as growth habit, flower color, nut weight, shell hardness and kernel taste carried high coefficients of variation. simple cor...

Carvalho M., Matos M., Carnide V., 2014. Fingerprinting of Vaccinium corymbosum cultivars using DNA of fruits. Hort. Sci. (Prague), 41: 175–184. In recent years the production and consumption Vaccinium corymbosum has increased. Highbush blueberry cultivars are divided into three types, northern, intermediate and southern. The traditional methods for classification of highbush blueberry cultivar...

date palm spider mite is one of the major pests of date palm in khuzestan.this pest damages fruits in orchards. in the present study responses of 30 native date palm cultivars of khuzestan were evaluated by assessment of pest infestation severity and fruit damage characteristics. based on the responses, cultivars were clustered into four groups as very highly infested cultivars including liloei...

In the present study, RAPD-PCR was used to assess genetic diversity of the rye including landrances and new rye cultivars coming from Central Europe and the Union of Soviet Socialist Republics (SUN). Five arbitrary random primers were used to determine RAPD polymorphism in the set of 38 rye genotypes. These primers amplified altogether 43 different DNA fragments with an average number of 8.6 fr...

olive is a perennial evergreen tree which has good adaptability to poor environmental conditions such as salt and drought resistance. in recent years, there is a tendency to plant olive trees in green spaces. therefore, this study was carried out to evaluate 15 olive cultivars regarding growth habit, form, and texture to recommend for landscape. six-year-old trees of 15 olive cultivars, which h...
