Protein Mobilisation And Proteolytic Activities In Root Tubers Of Asphodelus Aestivus, Serap Kirmizi, Gürcan Güleryüz, Hülya Arslan
Turkish Journal of Botany
We studied protein mobilisation in Asphodelus aestivus Brot. (Liliaceae) during a 1-year period. The activities of 3 proteolytic enzymes, endopeptidase (EP), leucine aminopeptidase (LAP), and carboxypeptidase (CP), together with soluble protein levels and total nitrogen and water content in root tubers were investigated. We found that protein mobilisation continued throughout the year. The highest levels of the 3 proteolytic enzymes were found in different months: LAP in December (1.19 ± 0.19 µmol pNA/g FW), CP in February (14.19 ± 1.13 µmol Leu/g FW), and EP in May (5.18 ± 0.12 U/h). Activities of LAP and CP generally reached their higher …

The Effects Of Arbuscular Mycorrhizal Inoculations And Cotyledon Removal On Early Seedling Growth Of Pongamia Pinnata, Anuradha Jha, Madhvi Kamalvanshi, Anil Kumar, Neha Chakravarty, Ashok Shukla, Shiv Kumar Dhyani
Turkish Journal of Botany
Pongamia pinnata (L.) Pierre, a fast-growing oil-seed-producing tree legume, has the ability to grow on wastelands. It can be utilized for biofuel plantation on such lands. The preconditioning of young seedlings during the early stage of development with efficient arbuscular mycorrhizal fungi (AMF) confers several benefits enhancing the possibility of their establishment in fields after outplanting from nurseries. However, before recommending these fungi for inoculation, the suitable AMF species must be identified. Therefore, to determine the potential AMF species, 9 purified fungi (isolated from different sites) were tested for their growth promotion activity. The inoculated fungi were not able to …

The Performance Of Simple Artificial Floating Wetland Communities And Their Effects On Aquatic Nutrient Levels And Algal Abundance, Bradley L. Sleeth
UNF Graduate Theses and Dissertations
Harmful algal blooms are exponential increases in autotrophic microorganisms that proliferate in such a way that the surrounding environment, the local economy and the health of regional populations are negatively affected. Among the causes of these blooms are anthropogenic inputs of excess nitrogen and phosphorus into the environment through overfertilization. Floating treatment wetlands (FTW) have emerged as a novel method of reducing the negative impacts of these nutrient inputs by using artificial rafts to float normally emergent wetland plants on the surface of water bodies to assimilate excess nutrients. Because their use is so new, only limited research has been …

Comparison Of Oak And Sugar Maple Distribution And Regeneration In Central Illinois Upland Oak Forests, Peter J. Frey
Masters Theses
Although white oak (Quercus alba) dominated much of the mid-west and eastern US hardwood forests prior to European settlement, changes in disturbance frequencies and habitat fragmentation, coupled with other biotic pressures, are allowing sugar maple (Acer saccharum Marshall) to displace oak in the upland forest understory. Since our understanding of how disturbance mechanisms influence oak regeneration is not fully clear, there is lack of consensus on how to employ management practices. We collected seedling microhabitat data from 5 upland oak forest sites in central Illinois, each differing in age class and/or silvicultural treatment to determine: 1) Whether …
