Effect of Arbuscular Mycorrhizal Colonization on Ecological Functional Traits of Ephemerals in the Gurbantonggut Desert
SYMBIOSIS (2008) 46, 121-127 ©2008 Balaban, Philadelphia/Rehovot ISSN 0334-5114 Effect of arbuscular mycorrhizal colonization on ecological functional traits of ephemerals in the Gurbantonggut desert Y. Sun, X.L. Li, and G. Feng* College of Natural Resources and Environmental Sciences, China Agricultural University, Beijing I 00094, China, Tel. +86-10-62733885, Fax. +86-10-62731016, Email. [email protected] (Received August 14, 2007; Accepted February 7, 2008) Abstract The spring ephemerals are distinct and important flora in the Gurbantonggut desert, in central Asia and northwestern China. In order to understand the role of arbuscular mycorrhizal (AM) fungi on growth of ephemerals, a pot experiment was conducted in greenhouse conditions. Two desert ephemerals, Erodium oxyrrhynchum and Plantago minuta, were tested for their response to inoculation with two AM fungi, BEG 167 (Glomus mosseae) and BEG 141 (Glomus intraradices). The results showed that mycorrhizal colonization led to marked improvement in both the reproductive (timing of flowering and number of seeds) and vegetative (dry matter) phase of the two ephemeral plants. Dry weight per plant inoculated with AM fungi was 57 to 67 percent higher than the control in E. oxyrrhynchum and 8 to 11 times higher than the control in P. minuta. Anthesis was advanced by 14 to 17d in P minuta and 5 to 7d in E. oxyrrhynchum, respectively, when both plants were inoculated with AM fungi. Colonization of mycorrhizal fungi significantly increased the total number of seeds or fruits per plant. Water use efficiency and photosynthetic rates were significantly higher in inoculated E. oxyrrhynchum plants than those of non-inoculated plants. -

Recent work reports delayed leaf senescence under constant light availability in some spring ephemerals, such as wild leek ( Allium tricoccum ). This paper aims at establishing if tree canopy composition and phenology can influence the growth of spring ephemerals through changes in their phenology. -
Source–Sink Imbalance Increases with Growth Temperature in the Spring Geophyte Erythronium Americanum

E-mail: [email protected] Received 30 October 2010; Revised 11 January 2011; Accepted 17 January 2011 Abstract Spring geophytes produce larger storage organs and present delayed leaf senescence under lower growth temperature. Bulb and leaf carbon metabolism were investigated in Erythronium americanum to identify some of the mechanisms that permit this improved growth at low temperature. Plants were grown under three day/night temperature regimes: 18/14 °C, 12/8 °C, and 8/6 °C. Starch accumulated more slowly in the bulb at lower temperatures probably due to the combination of lower net photosynthetic rate and activation of a ‘futile cycle’ of sucrose synthesis and degradation. Furthermore, bulb cell maturation was delayed at lower temperatures, potentially due to the delayed activation of sucrose synthase leading to a greater sink capacity. -

Dutchess Dirt
Dutchess Dirt A gardening newsletter from: Issue #118, May, 2017 SPRING! (DON’T BLINK) By Joyce Tomaselli, CCEDC Community Horticulture Resource Educator Spring didn’t just spring this year - it leapt high into the air, did a few flips, twists, turns and finally landed with a bang. Blubs grew quickly into masses of color. Herbaceous perennials emerged from the soil overnight bursting into bloom a few days later. Trees and shrubs leafed out all seemingly at once, especially for those of us with allergies to pollen. Bees and flies filled the air along with a few butterflies. One evening last week along a wooded one-lane road, an amazing assortment of wildflowers was in bloom. Here are a few I photographed. All are native, most are ephemeral. Dutchman’s breeches, Dicentra cucullaria, are an ephemeral plant which prefers rich, moist, humusy soils in part shade. The flowers are usually white but sometimes pink, and are shaped like upside-down pantaloons. This stand is on a rocky steep hill right on the side of road, facing east. There’s a large sycamore tree which provides shade. The plants grow from miniature tubers. Their seed is spread by ants. Bloodroot, Sanguinaria Canadensis, is growing in deeper shade with more moisture. Each flower stalk emerges with a leaf wrapped around it, which then unfurls as the flower opens. The flowers close at night and are very short-lived; the leaves are interesting in their own right. Every part of the plant exudes a bright red-orange sap which was used by Native American Indians for dye. -

Abstract: Plants need water and energy for their growth and reproduction. However, how water and energy availability influence dryland plant diversity along the aridity gradient in water-limited re- gions is still lacking. Hence, quantitative analyses were conducted to evaluate the relative importance of water and energy to dryland plant diversity based on 1039 quadrats across 184 sites in China’s dryland. The results indicated that water availability and the water–energy interaction were pivotal to plant diversity in the entire dryland and consistent with the predictions of the water–energy dynamic hypothesis. The predominance of water limitation on dryland plant diversity showed a weak trend with decreasing aridity, while the effects of energy on plants were found to be significant in mesic regions. Moreover, the responses of different plant lifeforms to water and energy were found to vary along the aridity gradient. -
Chapter 3: Affected Environment
3. Affected Environment 3.1 Introduction This chapter presents relevant information regarding the environment in and around the Sonny Bono Salton Sea NWR and Coachella Valley NWR that may be affected by the implementation of the management actions for each Refuge as outlined in Chapter 4. The two Refuges within the Sonny Bono Salton Sea NWRC protect very different habitats and species; therefore, this Chapter presents on overview of the regional setting, followed by separate descriptions of the various physical, biological, cultural, social, and economic resources within the Sonny Bono Salton Sea NWR and the Coachella Valley NWR. These descriptions provide the basis for evaluating the beneficial or adverse consequences posed by proposed management alternatives within a regional and Refuge-specific environmental context. 3.2 Regional Setting The Refuges of the Sonny Bono Salton Sea NWRC are located within the 8,360-square-mile Salton Basin (also referred to as the Salton Trough), a large natural depression that extends for almost 200 miles through the Colorado Desert (a portion of the larger Sonoran Desert) from a narrow point at the base of the San Gorgonio Pass in Riverside County trending southeast to the Gulf of California in Mexico (refer to Figure 1-1). The basin, which is the result of a deep, down-dropped fault block, occurs along the San Andres Fault at a point where two major tectonic plates, the North American Plate and the Pacific Plate, move past one another. The Salton Basin is flanked on the northeast by the San Bernardino Mountains and is within the rain shadow of the Peninsular Range, which borders the basin to the southwest.
