Abstract:

Nassella Desvaux es un género de la tribu Stipeae, descrito originalmente para especies de América Central y Sudamérica, que consiste de plantas con flósculos obovados, gibosos, con callo obtuso, lema no estriada con márgenes superpuestos y aristas fácilmente deciduas. Pohl (1980), Barkworth y Everett (1987) y Barkworth (1990) definieron un concepto más amplio de Nassella, incluyendo muchas especies tradicionalmente colocadas en Stipa. Bajo tal interpretación, en México existen ocho especies de Nassella, las cuales se distribuyen ampliamente en el país. Este trabajo tiene como objetivo comenta

Punagrass ( Achnatherum brachychaetum (Godr.)

Both species have seed heteromorphism, but punagrass is an invasive whereas flechilla is a climax species. Experiments were conducted to determine the relative contribution of chasmogamous (CH) seeds and cleistogamous (CL) seeds to growth and reproduction of the two species. CH progeny of punagrass grew and developed fast, but progeny of the largest CL seeds of the first node allocated

Abandonment of agricultural land is currently one of the main land use changes in developed countries. This change has an impact at the economic level and from the point of view of conservation. Therefore, recovering these areas after abandonment is, in many cases, necessary for ecological restoration, especially as they can be invaded by exotic or dominant species, preventing recovery of the original plant species community. The objective of this study is to examine changes in plant species richness and composition after the application of different treatments to eliminate Amelichloa clandest

Abstract:

Plant diversity is associated with resilient ecosystems. Loss of plant biodiversity triggered by anthropogenic and climatic factors jeopardizes environmental stability and sustainable forage production. The understanding of biodiversity mechanisms and functional traits of species can help to design forage production systems to buffer against perturbations. Resilience and productivity are linked to plant species characteristics and interactions that enable them to recover from adverse conditions and compensate for the loss of susceptible species. Benefits of diversified crops including enhanced

Abstract:

Invasive, non-native plant species can alter soil microbial communities in ways that contribute to their persistence. While most studies emphasize mycorrhizal fungi, invasive plants also may influence communities of dark septate fungi (DSF), which are common root endophytes that can function like mycorrhizas. We tested the hypothesis that a widespread invasive plant in the western United States, cheatgrass (Bromus tectorum L.), influenced the abundance and community composition of DSF by examining the roots and rhizosphere soils of cheatgrass and two native plant species in cheatgrass-invaded

Abstract:

Grain from improved varieties of the perennial grass Thinopyrum intermedium (Host) Barkworth & D.R. Dewey is marketed under the trade name Kernza (common name intermediate wheatgrass, IWG). While a growing body of evidence is available on the nutritional quality of Kernza, gaps exist for components such vitamins and minerals and protein quality. Therefore, we performed two studies on early-generation breeding program material, characterizing nutritional quality by quantifying macronutrients, sugars, dietary fiber, amino acid profiles, fat composition, vitamins, minerals, carotenoids, antio

Intermediate wheatgrass (IWG, Thinopyrum intermedium, (Host) Barkworth & D.R. Dewey subsp. intermedium, 2n = 6x = 42) is a novel perennial crop currently undergoing domestication efforts.

While IWG is mostly resistant to Fusarium head blight (FHB), identifying genomic regions associated with resistance will help protect the crop from potential disease epidemics. An IWG biparental population of 108 individuals was developed by crossing parents differing in their response to FHB and bacterial l

The use of the perennial grain intermediate wheatgrass (Thinopyrum intermedium (Host) Barkworth & D.R.

However, references are scarce to demonstrate its potential influence in a context of a limited perennial grain growth phase, integrated into annual grain crops succession.

Thousand seed weights (TSW) were consistently different amongst plants, averaging from 6.28 to 9.62 g over the three harvest years.

Tall wheatgrass (Thinopyrum ponticum (Podp.) Barkworth and D.R. Dewey) is an important, highly salt-tolerant C3 forage grass. The objective of this work was to learn about the ecophysiological responses of accessions from different environmental origins under drought and salinity conditions, to provide information for selecting superior germplasm under combined stress in tall wheatgrass. Four accessions (P3, P4, P5, P9) were irrigated using combinations of three salinity levels (0, 0.1, 0.3 M NaCl) and three drought levels (100%, 50%, 30% water capacity) over 90 days in a greenhouse.
