Question: Is there a pattern in growth of annual rings in roots of perennial forbs in relation to climate and climate extremes in grassland ecosystems? Location: Semi-arid grassland in Duolun (42127 0 N, 116141 0 E, 1380 m a.s.l.), central Inner Mongolia, China. Methods: Main roots of three perennial species, Potentilla anserina L., Cymbaria dahurica L. and Lespedeza daurica Schindl., were sampled. Crosssections (10–15-mm thick) were produced from the proximal end of sampled roots using a… Expand

Annual rings of perennial forbs and mature oaks show similar effects of climate but inconsistent responses to fire in the North American prairie–forest ecotone
For the prairie–forest ecotone of central North America, research of the effects of climate and fire on the annual growth of nonwoody plant types is currently needed to compliment dendrochronologicalExpand
Comparative analysis of annual rings of perennial forbs in the Loess Plateau, China
This study collected the main roots of 11 perennial forbs species along the precipitation gradient in the Loess Plateau, and analyzed the growth rings in the secondary root xylem, finding that ten species showed distinct annual growth rings, and the anatomical patterns, including vessel size and density, varied considerably among different families.

Application of herb chronology: Annual fertilization and climate reveal annual ring signatures within the roots of US tallgrass prairie plants
It is concluded that annual rings in these tallgrass forb species from long-term experiments within Konza prairie of northeastern Kansas (USA) are significantly larger among plots that were fertilized annually with phosphorus or nitrogen + phosphorus in contrast to unfertilized control plots.

Roots of forbs sense climate fluctuations in the semi-arid Loess Plateau: Herb-chronology based analysis
It is shown that warming-induced water deficit has a significant negative effect on the growth of herbaceous plants in the Loess Plateau, implying that water availability plays a dominant role in regulating the growth forbs in semi-arid areas. Expand
These results are the first evidence of herbaceous annual ring sensitivity to sudden amelioration of resources as well as a significant loss of aboveground biomass. Expand
Belowground annual ring growth coordinates with aboveground phenology and timing of carbon storage in two tallgrass prairie forb species.
This study provides a new physiological link between how ring chronologies in herbs often accord with growing-season environment and further dissecting this phenomenon is vital in unlocking the potential of herb chronology. Expand
Under pressure: how a Mediterranean high‐mountain forb coordinates growth and hydraulic xylem anatomy in response to temperature and water constraints
This study reinforces the evidence that the response of high-mountain plants to climatic change under simultaneous temperature and drought stress is complex and that models that simply assume an increase in elevation as a response to higher temperatures may fail to predict future responses to climate change.

ABSTRACT The alpine ecosystem of the Rocky Mountains is experiencing significant increases in growing season length, summer maximum temperatures, and shifting patterns in precipitation. Alpine herbsExpand
Growth rings in roots of medicinal perennial dicotyledonous herbs from temperate and subtropical zones in China
Clear variations in growth rings of different genus or species were characterized in this study, and these findings proved the feasibility of applying herbaceous plant growth rings in age identification of traditional Chinese medicine. Expand
Anatomical convergence and diversity in the taproots of 16 herbaceous perennial species from subhumid New South Wales, Australia
The high proportion of parenchyma facilitates storage of non-structural carbohydrates and water that are used for resprouting after adverse environmental periods, and the wide variation in distribution and pattern of vessels and fibres reflects the wide taxonomic diversity of the studied species.

Growth Rings of Roots in Perennial Forbs in Duolun Grassland, Inner Mongolia, China
The results provide evidence that growth rings in roots of some perennial forbs in the Inner Mongolia grassland can serve as a new and useful indicator of past changes in the grassland environment. Expand
Annual rings in native and introduced forbs of lower Michigan, U.S.A.
This study sampled established individuals of dicotyledonous perennial herbs in different habitats in lower Michigan and analyzed the main roots for the presence of growth rings in the secondary xylem, finding clearly demarcated growth rings among introduced species and in disturbed habitats.

Comparative analysis of growth rings in perennial forbs grown in an Alpine restoration experiment.
Results of the present study indicate that conclusions drawn from previous studies suggesting that growth rings in the roots of forb species are most likely formed annually are also valid for alpine plants. Expand
Assessing the recent grassland greening trend in a long-term context based on tree-ring analysis: A case study in North China

Radial growth of Pinus sylvestris growing on alluvial terraces is sensitive to water-level fluctuations.
Results provide evidence that dominance of P. sylvestris on gravelly alluvial terraces is caused not only by tolerance of soil dryness and nutrient deficiency, as previously assumed, but also by a dynamic multilayered root system which allows adaptation to highly variable soil-moisture conditions.

Abstract Time-integrated normalized difference vegetation index (TI NDVI) derived from the multitemporal satellite imagery (1989–1993) was used as a surrogate for primary production to investigateExpand
Dry matter allocation and nitrogen productivity explain growth responses to photoperiod and temperature in forage grasses
The lower competitive ability of Festuca pratensis compared to D. glomerata was mainly associated with its lower specific leaf area and nitrogen productivity, while the stronger decline of its competitive ability during summer was probably related to the decreased allocation of dry matter to the roots at higher temperatures.
