Studying seed dormancy and its consequent effect can provide important information for vegetation restoration and management. The present study investigated seed dormancy, seedling emergence and seed survival in the soil seed bank of Stipa bungeana, a grass species used in restoration of degraded land on the Loess Plateau in northwest China. Dormancy of fresh seeds was determined by incubation ...

Based on numerical analyses of macromorphological characters, scanning electron microscopy observation of leaves and lemma micromorphology, as well as field observations, Stipa pennata subsp. ceynowae was described here as a new taxon from Poland. It differs from the most similar S. pennata subsp. pennata and S. borysthenica mainly by its longer ligules of vegetative shoots. The affinities of t...

BACKGROUND Root lifespan is an important trait that determines plants' ability to acquire and conserve soil resources. There have been several studies investigating characteristics of root lifespan of both woody and herbaceous species. However, most of the studies have focused on non-clonal plants, and there have been little data on root lifespan for clonal plants that occur widely in temperate...

Plants adapt to environment by plastic growth which will be transferred to offspring through transgenerational effect. Performance and response of maternal and offspring plant will affect population dynamics and community composition. However, it is scarcely understood how maternal nutrient environment affect the performance and response of offspring through transgenerational effect. Here we st...

Despite the fact that dry grassland vegetation on ultramafics has been object of continuous research in previous centuries, there remains a knowledge gap regard to initial stages ultramafic substrates. The Stipa-dominated grasslands Serbia and Kosovo representing various phases overgrowth rocks were present study. A total 213 relev?s made different steppe-like Stipa species-dominated including ...

Thirteen species of Pyrrhalta Joannis, 1865 with black elytron are reviewed. A key to species, photographs of aedeagus and habitus are provided. Pyrrhalta qianana sp. n. is described from Guizhou, China. Pyrrhalta martensi Medvedev & Sprecher-Uebersax, 1999 is newly recorded from China (Tibet).

Sequence-related amplified polymorphism (SRAP) and inter-simple sequence repeat (ISSR) markers were used to assess the genetic diversity within and among 15 natural populations of Stipa bungeana from the Loess Plateau of China. Using 15 SRAP primers, 504 (99.80%) polymorphic loci were detected, and 372 polymorphic loci (96.12%) were identified using 15 ISSR primers. At the species level, the S....

Enclosure is an effective strategy for enhancing soil carbon sequestration in the desert steppe. Soil organic (SOC) and its stock during changes plant community influence fertility global cycle. We studied SOC along with six types steppe of Inner Mongolia, northern China. The goal this study was to explore differences among communities while accounting effects environmental factors. collected 3...
