Turf performance and physiological responses of native species to summer stress in Northeast China.

Rapid rise in temperature in summer causes severe injury to cool-season turfgrass of both native species and introduced ones in Heilongjiang of Northeast China. The objectives of this study were to compare physiological responses to seasonal heat stresses and turf performances between native and introduced commercial accessions. Three Chinese native species ( and ) and three USA Kentucky bluegrass cultivars (ie.

Assessment of differences in morphological and physiological leaf lodging characteristics between two cultivars of Hippeastrum rutilum.

Background: Environmental lodging stress, which is a result of numerous factors, is characterized by uncertainty. However, several studies related to lodging in cereal crops have reported that lodging in the Hippeastrum rutilum environment is very rare. Hippeastrum rutilum is a garden flower with high ornamental value and abundant germplasm resources.

Beneficial Effects of Mixing Kentucky Bluegrass With Red Fescue Plant-Soil Interactions in Black Soil of Northeast China.

Continuous monoculture of cool-season turfgrass causes soil degradation, and visual turf quality decline is a major concern in black soil regions of Northeast China. Turf mixtures can enhance turfgrass resistance to biotic and abiotic stresses and increase soil microbial diversity. Understanding mechanism by plant-soil interactions and changes of black soil microbial communities in turf mixture is beneficial to restoring the degradation of urbanized black soils and maintaining sustainable development of urban landscape ecology.
