Abstract:

In this study three aspects of sexual reproduction in Everglades plants were examined to more clearly understand seed dispersal and the allocation of resources to sexual reproduction— spatial dispersal process, temporal dispersal of seeds (seedbank), and germination patterns in the dominant species, sawgrass (Cladium jamaicense). Community assembly rules for fruit dispersal were deduced by analysis of functional traits associated with this process. Seedbank ecology was investigated by monitoring emergence of germinants from sawgrass soil samples held under varying water depths to determine the

Abstract:

[Truncated abstract] Fire ephemerals are pioneer species that germinate in large numbers after fire and generally live for between six months and four years. Seeds produced during the short life span of these plants persist in the soil seedbank until a subsequent fire. This study examined the dormancy characteristics and germination requirements of ten Australian fire ephemeral species from five families. Seeds of four species germinated at one or more incubation temperatures in the laboratory, indicating that a proportion of their seedlots were non-dormant at the time of testing. Austrostipa

Fungicides have been developed to protect plants against diseases and pests, which cause serious problems such as the loss of germination and vigour. The aim of this study was to test the germination and vigour of maize (Zea mays L.) seeds treated with several fungicides Apron® Star 42 WS (difenoconazole, thiamethoxam, and metalaxyl-m), Apron® XL (mefenoxam), Celest® XL (fludioxonil, mefenoxam) and thiram in the laboratory.

To investigate vascular-plant phylogeny at deep levels of relationship, I collected and analyzed a large set of plastid-DNA data comprising multiple protein-coding genes and associated noncoding regions.

I also examined relationships within and among the major lineages of monilophytes (ferns and relatives), including their relationship to the remaining vascular plants. Overall, I

A test was conducted to evaluate the effect of two seed treatments on seven varieties of alfalfa. The treatments included Rhizocote, Rhizocote plus Apron plus Rovral and untreated seed. Significantly fewer seedlings emerged for the coated than the uncoated seed when planted on a pound for pound basis. First cutting alfalfa yields were neither increased nor decreased as a result of the seed treatments.

Abstract:

The seed storage proteins of oat are mainly represented by the globulins (75%) and the prolamins (10%). These proteins are only found in the endosperm and accumulate within protein bodies during the maturation of the oat seeds. Three genomic sequences encoding globulin polypeptides and one avenin genomic sequence encoding an oat prolamin (avenin) have been isolated and characterized. The respective promoters of these genomic clones were fused to the coding sequence of the $\beta$-glucuronidase reporter gene (GUS). These constructs, together with the entire sequence of a globulin gene, were tra

The influence of variation in style length on pollen flow and seed set was examined in six populations of Menyanthes trifoliata in southwestern British Columbia to evaluate Ganders' hypothesis that morphological distyly increases the fecundity of a diallelic self-incompatible plant. In five populations, Menyanthes was distylous and self-incompatible. The sixth population consisted of pins and morphological homostyles (thrums with unusually long styles). In each population morph frequency, pollen frequency, the composition of stigmatic pollen loads and seed set were estimated. Results from the

Abstract:

A trade-off between seed size and seed number is central in seed ecology, and has been suggested to be related to a trade-off between competition and colonization, as well as to a trade-off between stress tolerance and fecundity. Large seeds endure hazards during establishment, such as shading, drought, litter coverage and competition from other plants, better than do small seeds, due to a larger amount of stored resources in the seed. Small seeds, however, are numerous and small-seeded species are therefore more fecund. Moreover, a pattern with small-seeded species being associated with open

Abstract:

This work is a union of molecular biology and evolutionary biology in addressing questions regarding the evolution of organisms and their genes. This project focuses on major groups of seed plants (angiosperms, and four gymnosperms groups: conifers, cycads, Ginkgo and Gnetales). These organisms diverged roughly three hundred million years ago and evolved independently since then. Therefore, morphological characters have limited power in resolving their phylogeny. With the advancement of molecular methods, sequences of genes have been widely used in addressing evolutionary relationships. Plant

Abstract:

Bacterial blight of barley, caused by the bacterium Xanthomonas translucens, occurs sporadically in Arizona in sprinkler-irrigated barley. The pathogen is seed borne, and there are no resistant varieties of barley. Bacterial blight has been severe when contaminated seed is planted and favorable weather conditions, including spring rains and late frosts, occur in March and April. Methods for detection of the bacteria on seed have been established at The University of Arizona using both standard pathogenicity trials on barley seedlings and immunoassay techniques.

Abstract:

Alfalfa which is extremely salt tolerant during germination has been developed by researchers at the University of Arizona Carbohydrates were analyzed in the original parental gemiplasm 'Mesa- Sirsa' and Cycle₅Syn₂ and Cycle₈Syn₂ seed to determine why this seed could germinate in extremely saline conditions. Raffinose and sucrose were both significantly higher in the salt -tolerant germplasm compared to the parental germplasm; however, the magnitude increase of these free sugars was not sufficient to explain the increased ability of the seed to absorb water in a stress environment. The galacto

Abstract:

Bromus tectorum, an invasive winter annual, has displaced native vegetation throughout the western United States. Bromus tectorum litter influences nutrient cycling near the soil surface as well as plant establishment. Failed seed production of B. tectorum occasionally occurs in the field, with plants exhibiting weak flowering culms that turn straw-colored in spring when normal plants are green or purple in color. Because annual grasses transport most soluble carbon (C) and nitrogen (N) to reproductive organs, seed production failure results in significantly different fates for these nutrients

Abstract:

The antibacterial potency of the extracts of the seed of Garcinia kola (bitter kola) was investigated in this study against a panel of referenced, environmental and clinical bacterial strains. The killing rates of the active extract as well as their potential for combination antibacterial therapy with standard antibiotics were also elucidated using standard procedures. The aqueous and acetone extracts of the seed were screened for activity against 27 bacterial isolates. The aqueous extract exhibited activity mainly against Gram positive organisms with Minimum inhibitory concentration (MIC) val
