RAISE OF HIGH FROST-RESISTANT AGROPYRON–TRITICUM HYBRIDS
Вавиловский журнал генетики и селекции, 2014 One way of obtaining high-frost-resistant varieties of winter wheat is a wide hybridization with wild relatives, in particular, certain species of wheatgrass. The most promising frost resistance donor is Agropyron glaucum (Desf. ex DC) Roem. & Schult.

Caspian Journal of Environmental Sciences, 2007 Transpiration, as one of the components of hydrological cycle, has not been paid enough attention yet, while it is necessary for sound utilization of rangelands, mostly located in the arid and semiarid regions. The comparison of the different kinds of rangelands species in terms of transpiration rates provides range managers the required information to
