Carter, Sara Katherine. "TOLERANCE OF SEEDLING TURFGRASS SPECIES TO ALS INHIBITING HERBICIDES." UKnowledge, 2007. http://uknowledge.uky.edu/gradschool_theses/429.

Full text

Abstract:

Acetolactate synthase (ALS) inhibiting herbicides are commonly used to eliminate weeds from mature turfgrasses. Field trials were conducted from 2004-2006, testing ALS herbicides for preemergence and early postemergence activity on newly seeded turfgrasses, using four species: Riviera bermuda, Zenith and Companion zoysia, L- 93 creeping bentgrass, and Poa annua L. Data collected were phytotoxicity and percent turf cover. Bermuda and zoysia herbicides were metsulfuron-methyl (42 g ha-1), trifloxysulfuron (29 g ha-1), flazasulfuron (53 g ha-1), foramsulfuron (30 g ha-1), bispyribac-sodium (112 g

Abstract:

Buffelgrass (Pennisetum ciliare (L.) Link), a non-native perennial bunchgrass, invades ecologically intact areas of the Sonoran Desert. It competitively excludes native plants and increases fire frequency and intensity. Since the 1990s, whole buffelgrass plants have been manually uprooted and removed to control the invasion in southern Arizona. Uprooting plants results in bare, disturbed soil which promotes buffelgrass seed germination. This study examined whether leaving entire uprooted buffelgrass plants (thatch) on a field site reduces future buffelgrass establishment compared to removing u

Abstract:

Bibliography: pages 140-167.<br>The seed and seedling ecology of the ericoid fynbos shrubs Passerina paleacea and Phylica ericoides were studied. These species co-occur in dune fynbos and are dependent on soil seed banks for regeneration after recurrent fynbos fires. Phylica was stimulated by the heat effect of fire. The precise germination cue for Passerina could not be determined, although circumstantial evidence pointed to the role of an indirect fire effect associated with the removal of vegetation. The seed banks of both species were seasonally persistent, and were not substantially deple

Abstract:

Background : Old fields are abandoned agricultural areas that are undergoing secondary succession. A variety of factors influence the assembly, invasibility, and species turnover during secondary succession in old fields. Old fields are important ecological research locations as an increasing amount of agricultural land is abandoned worldwide. Objectives : 1) To determine if exotic and native "invaders" display differences in invasion success in an old field, and 2) To observe how native and exotic species abundances change over the course of secondary succession under predictable disturbance

Full text

Abstract:

A major goal in restoration is to reestablish native plant communities. There are several ways to reestablish species, but for large areas the most logistically feasible approach is to sow seed of desirable species. However, most wetland seeds are buoyant and are extremely difficult to establish in designated areas before floating away. In upland areas, tackifiers have been used to stabilize hill slopes from erosion and to keep seeds in place. The tackifier works as an adhesive that binds the seeds to the soil. However, the use of a tackifier has not been widely employed in wetland restoration

Abstract:

Studies of seed dynamics and seedling establishment at the community level in savanna ecosystems are scant, particularly in the tropical savannas of Central Brazil. The Brazilian savannas (cerrado) have the largest diversity of plant species among Neotropical savannas. Cerrado vegetation exhibits consistent changes in tree density and tree size along shallow topographic gradients. Vegetation types differ from closed savannas with high tree density, and a nearly continuous canopy cover in the uppermost portions, to open savannas with scattered short trees in the low portions of the topographic

Abstract:

Forest regeneration in the form of successful seedling establishment is a key factor for the persistence of a healthy forest ecosystem. Tree seedlings grow in a complex environment shaped by over- and understory and competition for light, nutrients and water. Not much research has been done on how climate change is impacting on seedling performance through direct and indirect warming effects including possible interactions with the growth environment i.e. understory vegetation. To elucidate these, seedlings of B. pubescens, P. sylvestris and P. abies were planted into a full-factorial experime

Pythium diseases are common in the greenhouse production of tobacco transplants and can cause up to 70% seedling loss in hydroponic (float-bed) greenhouses.

The survey revealed twelve Pythium species. Approximately 80% of the surveyed greenhouses harbored Pythium in at least one of four site

Abstract:

The genus Tsuga is comprised of eight extant species found in North America and East Asia and four species represented by fossils from Europe and Japan. This study presents the first phylogenetic analysis based on structural, biochemical, and molecular sequence data. Characters obtained from published and unpublished literature were combined with new morphological characters from seeds, seedlings, and leaf cuticle material. Results from parsimony analyses of these characters differed from the published molecular based phylogeny. The non-molecular based phylogeny resolves two separate clades, a

Abstract:

L’écologie de la restauration est une discipline scientifique qui a vu le jour il y a une quarantaine d’années pour tenter de compenser les impacts négatifs du développement des sociétés sur les écosystèmes. Aujourd’hui, suite à des méta-analyses planétaires révélant le succès relatif des opérations de restauration écologique, une nouvelle question émerge : faut-il restaurer activement ou laisser en libre évolution les écosystèmes dégradés ? C’est dans ce contexte que ce projet de thèse a eu lieu avec une démarche qui s’est voulue pluridisciplinaire et a porté sur l’étude de l’impact de carriè

Abstract:

The process of environmental degradation that has been occurred in the lower region of Sao Francisco s river is reducing the permanent preservation areas. The artificial regeneration is a method of riparian restoration widely used to reconstitute the native vegetation in degraded areas. For the reasons set was a work of restoration in an area of riparian forest in Santana do São Francisco s county Sergipe, with the objective of proposing models to restore the natural balance of the environment. The studied area after tested was monitored for 60 months, using the experimental design in random
