Ulmus glabra Hudson, or Wych elm, occurs as fragmented and relict natural populations in the Central System, which acts as a refugium in the Iberian Peninsula. Considering the importance of the Central System populations of U. glabra, the main objective was to assess their genetic diversity using nuclear microsatellite markers. A total of 360 different genotypes were detected in the 427 U. glab...

wych elm (ulmus glabra hudson) is one of the forest species in hyrcanian forests of iran and considered as threatened species due to its narrow ecological range, over-exploitation, as well as dutch elm disease. in order to evaluate the possibility of cryopreservation of ulmus glabra seeds for long-term preservation, seeds were collected from natural habitats and three pre-treatment methods incl...

The conservation of genetic resources in cryocollections requires reliable protocols for the cryopreservation and regeneration preserved material. With Ulmus glabra, thawed buds by vitro organogenesis has suffered from low shoot growth high contamination rates. dehydration before improved rate ameliorated cultures initiated buds, although degree success varied depending on donor tree.

Tetraneura (Tetraneurella) nigriabdominalis (Sasaki, 1899) is a holocyclic and heteroecious species widely distributed throughout the world. Its primary hosts are various elm species, on which it forms galls. The results of this study complement those previous research development T. hosts. Our was conducted two Ulmus minor glabra, at three locations for successive seasons between 2017 2019. Fu...

Важливим завданням, без виконання якого неможливе розширення асортименту деревних рослин, що сприятиме збереженню їхнього біорізноманіття та раціональному використанню рослинних ресурсів, є встановлення їх репродуктивної здатності найоптимальніших методів розмноження. Наведено результати дослідження узагальнення роботи щодо особливостей вегетативного розмноження і вирощування садивного матеріал...

Elms are threatened by Dutch elm disease, and conservation methods needed to protect their genetic diversity. Cryopreservation of dormant buds allows large numbers genotypes be conserved with small space requirements minimal upkeep. through slow controlled cooling was tested for both species native Finland, Ulmus glabra laevis. Regeneration the thawed micropropagation studied on different basal...
