Significant Difference

The need for regionally adapted native grass seed sources for the northern Great Plains has resulted in the commercial release of a range of plant materials, including ecovars™ 1 . Ecovars™ are multisite composite populations developed to combine broad genetic diversity from a geographic region. The objective of this study was to determine whether morphological data could be used to distinguish between genetically diverse blue grama [Bouteloua gracilis (Willd. ex Kunth) Lag. ex Griffiths] seed sources through classical statistical methods. Entries included a Manitoba (MB) ecovar™, a USDA–NRCS released cultivar ‘Bad River’, and ecotypes from Wyoming and Minnesota. Vegetative and reproductive measurements and ratings were taken from a spaced-plant nursery during 2000–2001 in Carman, Manitoba, Canada. The results were analyzed using statistical techniques including: ANOVA, least significant difference, canonical discriminant analysis (CDA), and coefficients of variation. These techniques distinguished four genetically diverse seed sources from each other through CDA. As hypothesized, there was greater within-population genetic diversity for the MB ecovar™ and Wyoming and Minnesota ecotypes, compared with ‘Bad River’. Our results indicate that genetically diverse blue grama seed sources can be distinguished, based on phenotypic measurements.

Tebuthiuron has been found in soils and plants a decade after application to rangelands in semi-arid areas. Forage production, length of growing season, and preference by grazing animals are greater on treated than on untreated areas. It is not understood how these differences occur. Blue grama forage was assayed for concentrations of N, P, K, Ca, Cu, Fe, Mg, Mn, and Zn in treated and untreated plants on adjacent paired plots in the field, 6 to 11 yr after tebuthiuron applications at three locations in Arizona. Only Fe and Mn concentration differed among treatments, being significantly higher (P = 0.05) in blue grama from treated plots.

The influence of NaCl concentration on seed germination in blue grama grass (Bouteloua gracilis), salty alkaligrass (Puccinellia distans) and Kentucky bluegrass (Poa pratensis) were investigated. When seeds were germinated in petri dishes containing 0, 2.5, 5.0, 7.5, 10, 12.5, 15, 17.5, 20, 22.5, 25, 27.5, and 30 g·liter–1 NaCl at 22 C for 4 weeks, blue grama grass was most salt-tolerant with 50% germination at 17.5 g·liter–1. The salt concentrations that provided 50% germination for salty alkaligrass and Kentucky bluegrass were 5 and 1.5 g·liter–1, respectively. The upper limits of salinity that allowed any germination were 30 g·liter–1 (1%) for blue grama grass, 27.5 g·liter–1 (1%) for salty alkaligrass, and 5 g·liter–1 (2%) for Kentucky bluegrass. Germination was quickest in blue grama grass (90% germination in 1 week) followed by salty alkaligrass (50% in 3 weeks) and Kentucky bluegrass (50% in 4 weeks). The tissue contents of Na+ and Cl– as influenced by increasing levels of NaCl were also determined.

ABSTRACT Root endophytes are a promising tool for increasing plant growth, but it is unclear whether they perform consistently across plant hosts. We characterized the blue grama (Bouteloua gracilis) root microbiome using two sequencing methods, quantified the effects of root endophytes in the original host (blue grama) and an agricultural recipient, corn (Zea mays), under drought and well-watered conditions and examined in vitro mechanisms for plant growth promotion. 16S rRNA amplicon sequencing revealed that the blue grama root microbiome was similar across an elevation gradient, with the exception of four genera. Culturing and Sanger sequencing revealed eight unique endophytes belonging to the genera Bacillus, Lysinibacillus and Pseudomonas. All eight endophytes colonized corn roots, but had opposing effects on aboveground and belowground biomass in each plant species: they increased blue grama shoot mass by 45% (19) (mean +/− SE) while decreasing corn shoot mass by 10% (19), and increased corn root:shoot by 44% (7), while decreasing blue grama root:shoot by 17% (7). Furthermore, contrary to our expectations, endophytes had stronger effects on plant growth under well-watered conditions rather than drought conditions. Collectively, these results suggest that ecological features, including host identity, bacterial traits, climate conditions and morphological outcomes, should be carefully considered in the design and implementation of agricultural inocula.
