Flowering Phenology And Pollination Biology Of Ceropegia Thailandica Meve And Ceropegia Suddeei Kidyoo, Chayanin Kraithep Jan 2018

Flowering Phenology And Pollination Biology Of Ceropegia Thailandica Meve And Ceropegia Suddeei Kidyoo, Chayanin Kraithep

Chulalongkorn University Theses and Dissertations (Chula ETD)

The flowers of the genus Ceropegia have complex structures that involve in pollination mechanism. These structres gynostegium, pollinarium and corona. Moreover, the corolla tube which is inflated at base and the corolla lobes are connate only at tip forming a cage-like structure functions as a trap. When pollinators are attracted to flower, they could be temporarily trapped inside the flower. From previous studies, there are about 18 species in Thailand. Most Thai species have flowers characterized by a long narrow corolla lobe with distinct inflated basal portion. However, some species have a short corolla tube, such as C. thailandica Meve. …


Taxonomic Revision And Pollination Biology Of Orchid Genera Crepidium Blume And Dienia Lindl. (Malaxidinae, Orchidaceae) In Thailand, Anchalee Nuammee Jan 2018

Taxonomic Revision And Pollination Biology Of Orchid Genera Crepidium Blume And Dienia Lindl. (Malaxidinae, Orchidaceae) In Thailand, Anchalee Nuammee

Chulalongkorn University Theses and Dissertations (Chula ETD)

The terrestrial orchid Crepidium Blume and Dienia Lindl. in Thailand were enumerated by Gunnar Seidenfaden under Malaxis with key and drawings. Because of no species descriptions in publication, it is difficult to delimit species boundary. Moreover, recent discovery of new species results in unreliable assessment of species, therefore, the taxonomic revision of Crepidium and Dienia in Thailand should be carried out. The results indicated that the column and transversal callus on labellum are taxonomically important characters to delimit these two genera. In addition, morphological characters, i.e. stem and leaf morphology, labellum auricles, margins and number of teeth on distal margin …

Flower Meanings: Are They Relevant Today?, Dakota R. Moore

Murray State Theses and Dissertations

This qualitative study sought to describe contemporary views of ten selected flower specimens regarding the feelings they evoke in thirty participants divided evenly across three generations: Baby Boomers, Generation X, and Millennial. Little research exists in the scholarly body of knowledge regarding definitions of flowers; however, industry publications have captured some traditionally held definitions of some flowers. This phenomenological study utilized participants in the three generations of interest by showing each participant photos of ten selected cut flower specimens and asking them five questions about the emotions evoked by each flower, how they would feel if they received each flower, …


Millennial-Scale Trends And Controls In Posidonia Oceanica (L. Delile) Ecosystem Productivity, Carman Leiva-Dueñas, Lourdes López-Merino, Oscar Serrano, Antonio Martínez Cortizas, Miguel-Angel Mateo Jan 2018

Millennial-Scale Trends And Controls In Posidonia Oceanica (L. Delile) Ecosystem Productivity, Carman Leiva-Dueñas, Lourdes López-Merino, Oscar Serrano, Antonio Martínez Cortizas, Miguel-Angel Mateo

Research outputs 2014 to 2021

Posidonia oceanica is a marine phanerogam that buries a significant part of its belowground production forming an organic bioconstruction known as mat. Despite Posidonia seagrass mats have proven to be reliable archives of long-term environmental change, palaeoecological studies using seagrass archives are still scarce. Here we reconstruct four millennia of environmental dynamics in the NE coast of Spain by analysing the carbon and nitrogen stable isotopic composition of P. oceanica sheaths, the proportion of different seagrass organs throughout the seagrass mat and other sedimentological proxies. The palaeoenvironmental reconstruction informs on long-term ecosystem productivity and nutrient loading, which have been linked …


Conservation And Variation Of Dna Methylation In Lactuca Sativa And Lactuca Serriola, Trudi A. Baker Dec 2017

Conservation And Variation Of Dna Methylation In Lactuca Sativa And Lactuca Serriola, Trudi A. Baker

Graduate Doctoral Dissertations

Molecular techniques for guiding plant breeding have successfully used wild progenitors of domestic crops as sources of genetic variants conveying desirable traits. However, epigenetic variation, in particular DNA methylation, is a significant source of phenotypic variation and epigenetic effects of plant domestication are poorly understood. Described herein are the first single-base pair resolution methylomes of the highly valued crop iceberg lettuce (Lactuca sativa cv. Salinas) and its close relative, and ubiquitous weed, L. serriola. This work suggests several roles for acquisition and inheritance of methylation in the evolution of Lactuca spp. in response to stress. The Lactuca spp. have conserved …


Exploring Technological Strategies For Valorization Of Solid Sisal Waste: A Research Review, Amelia Kivaisi, Anthony Mshandete Dec 2017

Exploring Technological Strategies For Valorization Of Solid Sisal Waste: A Research Review, Amelia Kivaisi, Anthony Mshandete

Tanzania Journal of Science

The sisal industry in Tanzania generates large amounts of waste which is an un-tapped bioresource. Research was undertaken to establish appropriate technologies  for its valorisation to mushrooms, biogas and biogas manure (BGM).Physical and biological pre-treatments achieved methane yield increments of 23-30% whereas co-digestion with fish waste achieved methane yield increments of 59-94%. Sisal fibre waste was demonstrated to be a novel biofilm-carrier for treating sisal pulp leachate. With a loading rate of 9.0 kgVS/m3/day, the packed-bed bioreactor was operated without process stress. Sisal decortication waste (SLDW) and sisal boles (SBW) were found to be suitable for oyster mushroom cultivation. With …

Center for Plant Science Innovation: Faculty Publications

Storage roots of cassava (Manihot esculenta Crantz), a major subsistence crop of sub-Saharan Africa, are calorie rich but deficient in essential micronutrients, including provitamin A β-carotene. In this study, β-carotene concentrations in cassava storage roots were enhanced by coexpression of transgenes for deoxy-d-xylulose-5-phosphate synthase (DXS) and bacterial phytoene synthase (crtB), mediated by the patatin-type 1 promoter. Storage roots harvested from field-grown plants accumulated carotenoids to ≤50 lg/g DW, 15- to 20-fold increases relative to roots from nontransgenic plants. Approximately 85%–90% of these carotenoids accumulated as all-trans-β-carotene, the most nutritionally efficacious carotenoid. β-Carotene-accumulating storage roots displayed delayed onset of postharvest …

Health & Biomedical Sciences Faculty Publications

Recently, Sobierajska et al. (2016), using nSSR and morphology, showed that Juniperus drupacea exhibited differentiation between Greece and Turkey/ Lebanon, suggestive of Pleistocene genetic isolation. Here, we report that leaf terpenoids and DNA sequence data support their hypothesis by confirming differentiation between Greece and Turkey/ Lebanon/ Israel. The leaf oils of the Turkey/ Lebanon plants contained one unique terpene (trans-verbenol, 0.1-1.4%) that was absent in the Greece plants. The Greece oil contained three terpenes not found in the Lebanon/ Turkey plants: (ar)-curcumene (2.2%), β-alaskene (0.3%) and α-alaskene (0.4%). Four other terpenes were in higher concentration in the Greece oils: camphene …

Road Dust Correlated With Decreased Reproduction Of The Endangered Utah Shrub Hesperidanthus Suffrutescens, Matthew B. Lewis, Eugene W. Schupp, Thomas A. Monaco

Wildland Resources Faculty Publications

Roads associated with energy development have fragmented much of the Uinta Basin, the Colorado Plateau in general, and other areas of western North America. Beyond reducing available habitat, spreading exotic species, and creating barriers to dispersal, unpaved roads also increase dust loads on plants and pollinators, which may reduce plant growth and reproduction. We studied the effects of an unpaved road on reproduction of an endangered Utah endemic shrub. We measured the size and reproductive output of 156 plants and the dust deposition in plots at increasing distances from the road. We also hand outcrossed 240 flowers from 80 plants …

Agricultural and Environmental Sciences Faculty Research

The objective of the present study is to investigate nutritional and antioxidant activity of four types of organic tomato cultivars. The differences in tomato quality are also tested between groups with or without treatment using an organic biostimulator, Stimplex. Total phenolic compounds (TPC), lycopene, 𝛽-carotene, DPPH free radical scavenging activity, reducing power, and color parameters were investigated in the current study. The results showed that there was no significant difference in TPC among cultivars regardless of Stimplex treatment. Higher lycopene and 𝛽-carotene were obtained in Stimplex treated tomatoes. Lycopene and -carotene contents were significantly different among cultivars (𝑃<0.05). DPPH scavenging activity in controlled group was significantly higher than that in the Stimplex treated tomatoes (𝑃<0.05). No significant difference in reducing power was detected among cultivars treatment groups. The study showed that the darker the tomato color, the higher the lycopene and 𝛽-carotene contents and the stronger the reducing power.
