“…The plant is a stoloniferous dominant turfgrass native to the shortgrass prairies of the North American Great Plains (33). In this species, the nodes are spaced along the stolon in tight pairs that often develop highly symmetrical lateral branches on opposite sides of the stolon (Fig.…”

Recent evidence suggests that self͞non-self discrimination exists among roots; its mechanisms, however, are still unclear. We compared the growth of Buchloe dactyloides cuttings that were grown in the presence of neighbors that belonged to the same physiological individual, were separated from each other for variable periods, or originated from adjacent or remote tillers on the same clone. The results demonstrate that B. dactyloides plants are able to differentiate between self and non-self neighbors and develop fewer and shorter roots in the presence of other roots of the same individual. Furthermore, once cuttings that originate from the very same node are separated, they become progressively alienated from each other and eventually relate to each other as genetically alien plants. The results suggest that the observed self͞non-self discrimination is mediated by physiological coordination among roots that developed on the same plant rather than allogenetic recognition. The observed physiological coordination is based on an as yet unknown mechanism and has important ecological implications, because it allows the avoidance of competition with self and the allocation of greater resources to alternative functions.Buchloe dactyloides ͉ competition ͉ development ͉ phenotypic plasticity ͉ physiological coordination V irtually all multicellular organisms possess recognition systems that allow them to distinguish self from non-self with precision (1-4). For example, self͞non-self recognition systems enable the prevention of inbreeding by self-pollination in plants (4-5) as well as the cooperation between kin in various clonal marine invertebrates (6-8). Because competition entails allocation of limiting resources to nonreproductive functions (9-11), natural selection is expected to favor mechanisms that minimize wasteful competition among parts of the same individual (12), clonemates, and kin (13).Recent evidence suggests that roots are able to alter their growth according to the presence or absence of specific neighbors (14) and to segregate spatially in ''territories'' (15). The evidence also suggests the existence of two different types of self͞non-self discrimination among roots. (24,31), it is usually not studied in the context of self͞non-self interactions. However, the results of previous studies suggest the involvement of physiological coordination in self͞non-self root discrimination (18,20,21). The prevention of contact inhibition between roots of the same A. dumosa plant (18) as well as the avoidance of self competition between roots of F. chiloensis (20) was found to be at least partially based on physiological coordination between roots that develop on the same plant. In an earlier study, P. sativum plants were grown so that they had two roots and two shoots that could be either longitudinally separated into two genetically identical but physiologically distinct individuals or left intact. Root growth was significantly greater in the presence and the direction of roots that belonged to different plants,...

“…Whereas P. nuttalliana, a native to North America, occupies most arid regions from Wisconsin to British Columbia, south to Kansas, New Mexico, and California (Hitchcock, 1971). Both species are considered to be among the most salt tolerant C 3 grasses in North America and are often associated with areas of low site productivity (Ashraf et al, 1986;Harivandi et al, 1983;Macke and Ungar, 1971;Mintenko et al, 2002;Salo et al, 1996). Nuttall's alkaligrass has been documented on saline depressions (Macke, 1969), and along saline lake margins (Brotherson, 1987).…”

“…The minimum required score for sward density and overall quality was 5.0 points [23][24]. In 2010-13, Yara Mila Complex mineral fertilizer (N 12% + P 11% + K 18% + Mg 2.7% + S 8% + addition of B, Fe, Mn, and Zn) was applied twice a year: in early spring (250 kg ha -1 ) and in fall (150 kg ha -1 ), whereas a nitrogen fertilizer was applied at the beginning of the growing season and then after every third mowing at the rate of 20-30 kg N ha -1 .…”

This paper presents the physicochemical properties of soil and functional characteristics of sward on a grass runway of the airport in Gryźliny near Olsztyn (NE Poland). Soil samples for physicochemical analyses were collected from the surface layer (5-15 cm), and the overwintering success, density, color, and overall quality of the sward at 12 sites were graded on a nine-point scale in 2010-13. Long-term operation of the airstrip influenced the physical properties (compaction) of the substrate and diversified the functional characteristics of sward. The soil was classified according to Polish Soil Classification 2011 as proper rusty soil, and it was classified according to IUSS Working Group WRB 2014 as Brunic Arenosol (Dystric). The evaluated soil had high content of organic matter determined as loss-on-ignition ranging from 17.3 to 18.5%, which is a typical feature of sod layers. The content of macronutrients (N-NO 3 , P, K, Mg) as well as selected micronutrients (Cu, Zn) was low. Nutritional status of the studied soil was caused by its sandy texture. The analyzed sward was characterized by moderate overwintering success, good density (in particular in fall), green and fresh green color, and satisfactory-to-good visual merit. The condition of the sward covering the runway was affected by the physicochemical properties of the soil as well as aircraft operations (take-offs and landings), applied management practices, and weather conditions during the study.
