Germination Behaviour of Four Mediterranean Cistus L. Species in Relation to High Temperature
Ecological Questions 12/2010 – Special Issue: 175 – 186 DOI: 10.2478/v10090–010–0011–2 Germination behaviour of four mediterranean Cistus L. species in relation to high temperature Domenica Scuderi, Rosa Di Gregorio, Stefania Toscano, Carla Cassaniti, Daniela Romano Department of Horticulture and Food Technology, University of Catania, Via Valdisavoia 5, 95123 Catania, Italy, e-mail: [email protected] Abstract. Cistus is one of the most characteristic genera of the Mediterranean flora. These species, natives of lands surrounding the Mediterranean Sea, are present in scrubland and garigue on siliceous ground and often on acid soil; seven species in particular are founded in Sicily. The adaptation of the genus to Mediterranean environments is evident from ecological characteristics such as fire- dependent seed germination; the heat generated by fire is in fact a key germination input. In this view, two experiments were performed to study the effects of high temperature on germination of four Cistus species (C. creti- cus L., C. crispus L., C. monspeliensis L., C. salviifolius L.). In the first, in relation to untreated control, 7 different high temperature pre-treatments (from 70°C to 130°C) for different timings (from 1 to 10 minutes) were analysed in relation to two sowing strategies (soon after the seed collection and after a 6 month period at 5°C to simulate the winter season effects). The pre-treatment with high temperatures can improve the germination; the storage at 5°C to simulate the winter season effects did not modify the germination process. In any case the results showed a species-dependent response. -

Fire-Resistant Plants for Oregon Home Landscapes
FFire-ire-RResistantesistant PlantsPlants forfor OregonOregon HomeHome LandscapesLandscapes Suggesting specific types of vegetation that may reduce your risk from wildfire. Stephen Fitzgerald Area Extension Forester and Associate Professor Amy Jo Waldo Area Extension Horticulture Agent and Assistant Professor OSU Extension Service 1421 S. Hwy 97, Redmond, OR 97756 Introduction Oregon has many wildfire prone areas. In these places, fires are a natural part of the changing landscape. As homes are built in these areas, special precautions must be taken by the homeowner to pro- tect their property. Installation of fire- resistive roofing is critical to preventing firebrands from igniting the home from a roof fire. Well maintained fire-resistant vegetation and irrigated landscape is also critical within close proximity of a home. These actions DO NOT insure that your home will survive a wildfire, but they provide for a good chance of structural survival. Implementation of FireFree [www.firefree.org] and FireWise [www.firewise.org] activities can also significantly improve chances of a home surviving a wildfire. Fire-resistant vegetation. When landscaping around a home, most homeowners are interested in creating a landscape that is aesthetically pleasing, compliments their home, and has varia- tions in color, texture, flowers, and foliage. If your home is located in or adjacent to forests or rangeland, you should also consider the flammability of plants within your home landscape. Flammable plant material in your land- scape can increase the fire-risk around your home. The 1991 Oakland Hills Fire in California is a prime example of how flam- mable plant material (Eucalyptus trees) can act as fuel and contribute to the inten- sity of a wildfire. -

The genetics, nature and occurrence of self-and cross-incompatibility in four annual species of Coreopsis L. by Jagan Nath Sharma A thesis submitted to the Graduate Faculty in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY in GENETICS Montana State University © Copyright by Jagan Nath Sharma (1971) Abstract: Four annual species of Coreopsis L. (Compositae: Heliantheae: Coreop-sidinae), C. bigelovii. (A. Gray) H. M. Hall, C. calliopsidea (DC.) A. Gray, C. califomica (Nutt.) Sharsmith, and C. tinctoria Nutt., were studied to determine the genetics of their self-incompatibility mechanisms. Diallel -cross, backcross, and F2 studies revealed that these species have a sporo-phytic, multiple allelic, monogenic system of self-incompatibility. C. tinctoria had 7 multiple alleles, while C. bigelovii and C. califomica had 5 multiple alleles each. The number of multiple alleles could not be assigned to C. calliopsidea. Cytological studies' revealed a strong correlation between the sporophytic system of self-incompatibility and the stigma as the site of pollen inhibition. Meiotic chromosome numbers for all four species were determined as n=12. Secondary associations between different bivalents were found in all four species studied; these point toward some form of polyploidy associated with the genus. Significant heterosis for horticultural traits was detected and a method of producing F1 hybrid cultivars in Coreopsis tinctoria, using incompatibility as a technique, has been suggested.

Welcome to the 27Th Annual Wildflower Hotline, Brought to You by the Theodore Payne Foundation, a Non-Profit Plant Nursery, Seed
Welcome back to the 28th Annual Wildflower Hotline, brought to you by the Theodore Payne Foundation, a non-profit plant nursery, seed source, book store and education center, dedicated to the preservation of wildflowers and California native plants. The glory of spring has really kicked into high gear as many deserts, canyons, parks, and natural areas are ablaze of color – so get out there and enjoy the beauty of California wildflowers. This week we begin at the Santa Rosa and San Jacinto Mountains National Monument in Palm Desert, where the Randall Henderson and Art Smith Trails are ablaze with beavertail cactus (Opuntia basilaris), Arizona lupine (Lupinus arizonicus), little gold poppy (Eschscholzia minutiflora), chuparosa (Justicia californica), brittlebush (Encelia farinosa), desert lavender (Hyptis emoryi), wild heliotrope (Phacelia distans), and apricot mallow (Sphaeralcea ambigua). If you are heading to Palm Springs for the weekend, take a trip along Palm Canyon Dr. where the roadside is radiant with sand verbena (Abronia villosa), Fremont pincushion (Chaenactis fremontii), desert dandelion (Malacothrix glabrata), forget-me-not (Cryptantha sp.), Spanish needle (Palafoxia arida), Arizona Lupine (Lupinus arizonicus), and creosote bush (Larrea tridentata). While in the area check out Tahquitz Canyon, in the Agua Caliente Indian Reservation, off West Mesquite Ave., which is still decorated with desert dandelion (Malacothrix glabrata), pymy golden poppy (Eschscholzia minutiflora), white fiesta flower (Pholistoma membranaceum), California sun cup (Camissonia californica), brown-eyed primrose (Camissonia claviformis), and more. NOTE: This is a 2-mile loop trail that requires some scrambling over rocks. Just north of I-10, off Varner Road, Edom Hill is a carpet of color with Arizona lupine (Lupinus arizonicus), sand verbena (Abronia villosa), Fremont pincushion (Chaenactis fremontii), and croton (Croton californicus), along with a sprinkling of desert sunflower (Geraea canescens) and dyebush (Psorothamnus emoryi). -

Vegetation Descriptions NORTH COAST and MONTANE ECOLOGICAL PROVINCE
Vegetation Descriptions NORTH COAST AND MONTANE ECOLOGICAL PROVINCE CALVEG ZONE 1 December 11, 2008 Note: There are three Sections in this zone: Northern California Coast (“Coast”), Northern California Coast Ranges (“Ranges”) and Klamath Mountains (“Mountains”), each with several to many subsections CONIFER FOREST / WOODLAND DF PACIFIC DOUGLAS-FIR ALLIANCE Douglas-fir (Pseudotsuga menziesii) is the dominant overstory conifer over a large area in the Mountains, Coast, and Ranges Sections. This alliance has been mapped at various densities in most subsections of this zone at elevations usually below 5600 feet (1708 m). Sugar Pine (Pinus lambertiana) is a common conifer associate in some areas. Tanoak (Lithocarpus densiflorus var. densiflorus) is the most common hardwood associate on mesic sites towards the west. Along western edges of the Mountains Section, a scattered overstory of Douglas-fir often exists over a continuous Tanoak understory with occasional Madrones (Arbutus menziesii). When Douglas-fir develops a closed-crown overstory, Tanoak may occur in its shrub form (Lithocarpus densiflorus var. echinoides). Canyon Live Oak (Quercus chrysolepis) becomes an important hardwood associate on steeper or drier slopes and those underlain by shallow soils. Black Oak (Q. kelloggii) may often associate with this conifer but usually is not abundant. In addition, any of the following tree species may be sparsely present in Douglas-fir stands: Redwood (Sequoia sempervirens), Ponderosa Pine (Ps ponderosa), Incense Cedar (Calocedrus decurrens), White Fir (Abies concolor), Oregon White Oak (Q garryana), Bigleaf Maple (Acer macrophyllum), California Bay (Umbellifera californica), and Tree Chinquapin (Chrysolepis chrysophylla). The shrub understory may also be quite diverse, including Huckleberry Oak (Q. -

However, which traits can be used to evaluate drought tolerance remain an open question. Here, we conducted a common-garden experiment on 37 shrub species originating from desert to humid regions. The correlations between plant traits and the native environmental conditions were studied. Leaf sizes and Huber values were significantly correlated with most climate variables of the shrubs’ origins. The osmotic potentials at full turgor (π100), turgor loss point (YTLP), and midday leaf water potential (Ymid) were significantly correlated with most climate variables of their origins. We proposed using leaf sizes, Huber values, and YTLP as predictors of drought tolerance across shrub species and shrub biomes.
