The Ethnobotany Of Sweet Flag, Acorus Calamus L., Timothy J. Motley
The Ethnobotany Of Sweet Flag, Acorus Calamus L., Timothy J. Motley
Masters Theses
One of the more interesting and attractive components of aquatic ecosystems is sweet flag, Acorus calamus L., a herbaceous perennial belonging to the Araceae, a primarily tropical family. Sweet flag is one of the few extratropical members.
The primary purpose of this work is to present a compilation of the various traditional and contemporary uses of sweet flag by various cultures.
Information regarding the known ethnobotanical and economic uses of the rhizome and aromatic essential oil as a flavoring agent is given, as well as its medicinal uses and value as an insecticide. In addition, a discussion of the …
River Birch (Betula Nigra L.) Forest Communities In Cass And Mason Counties, Illinois, Charles Anthony Uhlarik
River Birch (Betula Nigra L.) Forest Communities In Cass And Mason Counties, Illinois, Charles Anthony Uhlarik
Masters Theses
During the fall of 1988 and the spring of 1989, four stands of river birch (Betula nigra L.) were surveyed in Cass and Mason Counties, Illinois. All study areas were divided into quadrats 25 m on a side (0.154 acres) and the maximum number of quadrats were placed to completely survey each forest. The relative density, relative dominance, and importance value was calculated for each species (dbh greater than 10 cm) in each forest area. Also, seedlings (less than 2.5 cm dbh) and saplings (2.5-10.0 cm dbh) were recorded in each area. River birch is the dominant overstory …

Tissue Culture In Rice (Oryza Sativa L. Subsp. Japonica Var. Lemont), Young M. Woo
Masters Theses
The purpose of this study was to obtain callus induction and subsequent plantlet regeneration from various explants of rice (Oryza sativa L. subsp. japonica var. Lemont). Callus induction occurred from the somatic cells of ovary wall, immature and mature embryos, immature endosperm, stem nodes, and seedlings. Plantlets were regenerated from embryo-, endosperm-, and stem node-derived calli on differentiation media. Stem nodes were the most responsive to callus induction. Requirements for optimal callus formation and plantlet regeneration differed from each culture. The study investigated the effects of cold treatment of explants, initial culture in darkness, media, and subculture for individual explant …
