GERMINATION, EMERGENCE, AND EARLY GROWTH OF SPARTINA PECTINATA An Abstract of a Thesis Submitted In Partial Fulfillment of the Requirements for the Degree Master of Science 10 Wade Herold Williams University ofNorthem Iowa May2001 ABSTRACT Spartina pectinata Link is frequently omitted from lowland prairie restorations because the seed often fails to grow when planted, and inclusion is limited to plugs of young plants. Anecdotal reports indicated improvement of seed germination following stratification. The effects of seed stratification on the germination of S. pectinata seed were systematically studied. Seed was obtained from both relict populations of plants and germplasm plants as defined by Englert and White (1977). Seed from 5 different collections were subjected to 4 different seed stratifying treatments: imbibed-chilled (1 oc for 15 to 45 days); imbibed-frozen (-12°C for 4 to 7 days); or dried-warmed (23 oc for 120 days); or aged (4°C for 1.5 to 2.5 years). Control (unstratified) seed for all trials was fresh, dried-chilled seed ofthe same collection, stored in a refrigerator at 4°C. In addition, seed from 4 collections planted in soil were subjected to 2 different seed stratifying methods (imbibed-chilled, imbibed-frozen) under greenhouse conditions. Emergence of germinating seedlings was monitored for post-emergence damping-off Also, seedlings from 2 collections were grown in the greenhouse and growth measurements were made weekly for 6 weeks after emergence from the soil. Control seed ranged in average viability from 66.5% (±7) to 99% (±1), in average germination from 59.5% (±7) to 94% (±2.2), and in average emergence from 38.5% (±3.8) to 84.5% (±6.8). The stratification treatments did not improve these values. Longer stratification periods at 1 oc for imbibed-chilled seed increased the germination percentage in the early phase of germination, this early increase was also reflected in coleoptile emergence from the soil. Total germination and emergence at the end of the trials were the same as the control. Stratifying seed by imbibed-freezing, dried-warming, or aging up to 1.5 years had no effect on its germination, though control seed germinated significantly better than 2.5-year old seed. Germination rates varied in collections from different sites. Post-emergence damping-off was not observed for any seed collection, but mildew became a problem for seed stratified by imbibed-chill beyond 45 days. For both relict and germplasm plants, the total length of leaves and roots steadily increased during the first 6 weeks. The majority of growth was below ground. Average seed depth decreased during early growth, rising several seed thicknesses from an average planting depth range of0.62 em (±0.11) to 0.69 em (±09). Endosperm starch levels steadily decreased through week 4 and were depleted by week 5. Six week-old seedlings had an average total shoot length range of30.40 em (±5.89) to 33 .32 em (±4.71) and an average total root length range of 139.40 (±39.40) em to 169.11 em (±52.42). It can be concluded from this study that Spartina pectinata should be included in prairie restoration projects, as viable seed will germinate readily with or without stratification.

Abstract This checklist has 785 species and 801 taxa (for taxa, the varieties and subspecies are included in the count) in 90 plant families. The most common plant families are the grasses (Poaceae) and the sunflower family (Asteraceae). Of this total, 513 taxa are definitely known to occur on the Comanche National Grassland. The remaining 288 taxa occur in nearby areas of southeastern Colorado and may be discovered on the Comanche National Grassland. The Author Dr. Donald L. Hazlett has worked as an ecologist, botanist, ethnobotanist, and teacher in Latin America and in Colorado. He has specialized in the flora of the eastern plains since 1985. His many years in Latin America prompted him to include Spanish common names in this report, names that are seldom reported in floristic pub- lications. He is also compiling plant folklore stories for Great Plains plants. Since Don is a native of Otero county, this project was of special interest.

Unpublished report. April 2009. 62 pages plus appendices. INTRODUCTION The Virginia Department of Conservation and Recreation's Division of Natural Heritage (DCR-DNH) was established to protect Virginia's Natural Heritage Resources. These Resources are defined in the Virginia Natural Area Preserves Act of 1989 (Section 10.1-209 through 217, Code of Virginia), as the habitat of rare, threatened, and endangered plant and animal species; exemplary natural communities, habitats, and ecosystems; and other natural features of the Commonwealth. DCR-DNH is the state's only comprehensive program for conservation of our natural heritage and includes an intensive statewide biological inventory, field surveys, electronic and manual database management, environmental review capabilities, and natural area protection and stewardship. Through such a comprehensive operation, the Division identifies Natural Heritage Resources which are in need of conservation attention while creating an efficient means of evaluating the impacts of economic growth. To achieve this protection, DCR-DNH maintains lists of the most significant elements of our natural diversity.

(Poaceae). The adult and immature stages are described herein, including diagnoses of the adult and larva, as this insect may be easily confused with a closely related grass-feeding congener, Blastobasis graminea Adamski, which is also known to occur in the United States. The biology of B. repartella is described. Figures of the adult, illustrations of the male and female genitalia, wing venation, the chaetotaxy of the larva (supplemented with scanning electron micrographs), and pupa are provided. Bassus difficilis (Hymenoptera: Braconidae) is reported as a larval/pupal parasitoid of B.
