Abstract:

Leaf anatomical and chemotaxonomic studies were carried out on the subtribe Gnaphaliinae (Inuleae - Compositae) with the aim of clarifying the status and relationships of the New Zealand and Tasmanian taxa. The leaf anatomy and flavonoid patterns of 48 species were compared. Data were analysed numerically and cladistically. The Gnaphaliinae is a problematical group, especially in terms of generic boundaries. In the leaf anatomical and chemotaxonomic analyses, the New Zealand species of AnaphaJis are similar to each other but quite different from a Himalayan representative (Anaphalis triplinerv

Abstract:

Salinity usually reduces plant growth in terms of height and biomass, but can increase secondary metabolite production. This frequently reported observation in guayule (Parthenium argentatum Gray, Asteraceae) was investigated for possible mechanisms.Osmotic and specific ion effects of four chloride salts (CaCl2, MgCl2, KCl, and NaCl) on leaf anatomical and plant physiological parameters were studied. One-year-old plants of guayule line AZ 2 were grown under two salt concentrations (750 ppm and 1500 ppm) for each salt type (plus a control) in sand culture (semi-hydroponic) for eight weeks under

The C<sub>4</sub> biochemical pathway is the most efficient form of photosynthesis in warm environments and introducing this system into globally significant, but less efficient, C<sub>3</sub> photosynthetic crops could bring major yield increases. The most photosynthetically efficient C<sub>4</sub> grass species have a specialised leaf anatomy characterised by high vein density with two distinct cell types radially arranged around the vascular bundles (Kranz anatomy). Although this anatomy was first described in 1882, the genetic regulators controlling Kranz development are still not known. I

Abstract:

The yield of crop dry matter is closely dependent upon the amount of solar radiation intercepted by the crop canopy. This in turn is primarily determined by the amount of leaf area and its persistence. This study was concerned with the influence of environments, nitrogen supply and plant density in controlling apical development and leaf growth and development in barley. Three series of experiments were carried out on sequentially sown spring barley (cv. Claret) to cover the whole range of the natural variation in environmental variables. In the first series of experiments there were 4 sowing

Abstract:

The C₄ photosynthetic cycle acts to concentrate CO₂ around the enzyme Rubisco. By doing so, C₄ photosynthesis leads to increased radiation, water and nitrogen use efficiencies. As such, C₄ photosynthesis is the most productive form of photosynthesis known. Because it enables such high levels of productivity there are large international efforts to introduce C₄ photosynthesis into non-C₄ crop species such as rice. Kranz anatomy is a characteristic leaf cellular arrangement of concentric rings of bundle sheath and mesophyll cells around closely spaced veins and is crucial to C₄ photosynthesis in

Leaf anatomy data gave little phylogenetic information. Sclerification associated with vascular bundles was systematically useful. Pollen data served to resolve taxa at the subtribal level.

The C<sub>4</sub> photosynthetic pathway acts to concentrate CO<sub>2</sub> around the enzyme Ribulose-1,5-bisphosphate carboxylase oxygenase (Rubisco), ensuring that it catalyses a carboxylation rather than oxygenation reaction, which in turn suppresses photorespiration. In nearly all cases C<sub>4</sub> photosynthesis is underpinned by characteristic Kranz anatomy, with concentric wreaths of bundle sheath (BS) and mesophyll (M) cells surrounding closely spaced veins. The increased yields associated with the C<sub>4</sub> pathway have lead to the suggestion that C<sub>3</sub> crops such as ri

A clear morphological distinction could be made between oat crown rust, wheat brown rust, barley brown rust, rye brown rust and the yellow rusts of wheat and barley.

Some species also have medicinal and other valuable properties.

Seasonality in the Amazon Rainforest is predicted to become more extreme, with dry seasons increasing in length and severity, while severe episodic droughts are expected to occur with greater frequency.

A key component in the drought-induced carbon flux is tree mortality, and there is evidence of strong feedbacks globally and regionally in the Amazon with climate change. Although the exact cause of

The tropical genus Clusia which contains species with C3, Crassulacean acid metabolism and C3/CAM properties is an interesting model to dissect anatomical, physiological and molecular traits that underpin the evolution of CAM photosynthesis.

CAM confers high water use efficiency (WUE) and has long been considered an adaptation to drought stress and high irradiance.

This thesis provides new knowledge on an understudied group of grasses, some of which are resurrection grasses (i.e. able to withstand extreme drought). The sole Australian species (Tripogon loliiformis) is morphologically diverse and could be more than one species. This study sought to determine how many species of Tripogon occur in Australia, their relationships to other species in the genus and to two other genera of resurrection grasses (Eragrostiella and Oropetium). Results of the research indicate there is not enough evidence, from DNA sequence data, to warrant splitting up T. loliiform

Apresenta grande plasticidade no que se refere aos ambientes de ocorrência, sendo encontrada em áreas com solos inundáveis, argilosos ou arenosos, secos ou úmidos, o que justifica sua ampla utilização em projetos de restauração em áreas inundáveis ou não.

Abstract:

O gênero Briza L. inclui cerca de 26 espécies, se aceito em seu sentido amplo, ou é restrito apenas a quatro espécies eurasiáticas, sendo as americanas distribuídas em diferentes gêneros, conforme o autor considerado. Como a sua taxonomia é motivo de muitas divergências entre os autores, as espécies de Briza e de gêneros relacionados têm sido tratadas como pertencentes ao Complexo Briza. O objetivo deste trabalho é verificar a importância da anatomia foliar, visando a fornecer subsídios para a taxonomia do Complexo Briza e para a análise de sua circunscrição.
