Adaptation of wheat (Triticum aestivum L.) to high temperatures could be improved by introducing alien genes from wild relatives. We evaluated the responses of wheat-Leymus racemosus chromosome introgression lines to high temperature to determine their potentiality for developing improved wheat cultivars. Introgression lines and their parent Chinese Spring were evaluated in a growth chamber at ...

The existence of a semipermeable layer in grass seeds has been extensively reported, yet knowledge of its influence on tests for seed viability and vigor that depend upon measurement of electrical conductivity (EC) is limited. This study determined the presence and location of the semipermeable layer, and its relation to seed viability and vigor assessment, in seeds of four important grass spec...

The tolerance of the dune grass Leymus mollis (Triticeae; Poaceae) to various biotic and abiotic stresses makes it a very useful genetic resource for wheat breeding. Wide hybridization between L. mollis and wheat allows the introduction of Leymus chromosomes into the wheat genetic background and facilitates the integration of useful traits into wheat. However, the genetic basis controlling the ...

Leymus mollis (Triticeae; Poaceae) is a useful genetic resource for wheat (Triticum aestivum L.) breeding via wide hybridization to introduce its chromosomes and integrate its useful traits into wheat. Leymus mollis is highly tolerant to abiotic stresses such as drought and salinity and resistant to various diseases, but the genetic mechanisms controlling its physiological tolerance remain larg...

The Stipa grandis steppe is a type of steppe in the Central Asian sub-region, and it is an important resource for livestock production in China. Mowing is one of the main management methods for this steppe. Verifying the response of the Stipa grandis steppe communities to different mowing frequencies is essential for the rational utilization of pastures and the protection and recovery of natura...

Win ISAREG is a model for performing soil water balance and estimating impacts of water stress on yields for crops, concentrating on the evaluation of irrigation scheduling. The soil water balance of different type of soil and crop were study in the typical semiarid Horqin Sandy land area in this paper. With the data from Agula experimental station and concentrate on site A3 with Artemisia and ...

Leymus chinensis (  (Trin.) Tzvel.) is a good perennial forage with palatability, high yield and feeding value. In addition, because of its strong resistance, can improve the disadvantaged environment such as poor land, it is an important species to protect grassland ecology in China. Therefore, order promote germination leymus seeds explore mechanism Germination, this study used...

Aims: The objective of the study was to investigate: (1) Ns genome donor and elucidate origins Xm Leymus; (2) evaluate phylogenetic relationships among these species.
 Methodology: CTAB (cetyltrimethylammonium bromide) procedure used extract total genomic DNA from fresh leaf tissue. A 150 pairs SSR primers were tested screen those produced polymorphic bands continue further analysis with E...

The high ionization efficiency of helicon discharges has been attributed to Landau damping and mode coupling to Trivelpiece-Gould (TG) modes. Though theory predicts the importance of TG modes, they have rarely been seen. Here they were detected directly by measuring their radiofrequency current with a J-dot probe, thus supporting the contention that TG modes play a role in these enigmatic plasm...

Timely harvest is critical to achieve maximum seed viability and vigour in agricultural production. However, little information exists concerning how to reap the best quality seeds of Leymus chinensis, which is the dominant and most promising grass species in the Songnen Grassland of Northern China. The objective of this study was to investigate and evaluate possible quality indices of the seed...
