Three Mississippi Ecotypes of Wetland Plants
نویسندگان
چکیده
-In 1996, the USDA-Natural Resources Conservation Service (NRCS) Jamie L. Whitten Plant Materials Center (PMC) released three locally collected, source identified wetland plants. Indian Bayou source powdery thalia (Thalia dealbata Fraser ex Roscoe) and Leflore source creeping burhead [Echinodorus cordifolius (L.) Griseb.] were collected in the Mississippi Delta and Leaf River source woolgrass [Scirpus cyperinus (L.) Kunth] from southeastern Mississippi. Both vegetative propagules and seedlings can be planted. PMC seed germination studies have shown that Indian Bayou and Leaf River germinate readily after exposure to cold, moist conditions (stratification). Indian Bayou germination and seedling growth was best in a moist, not saturated, growing medium, whereas best germination of Leaf River was in a saturated medium and seedling growth was better in moist medium. Germination of Leflore was very poor for all seed treatments in the test, even though seedlings have established in PMC plant production ponds.

Salt stress effect on some agronomical and physiological traits in Thymus daenensis subsp. daenensis ecotypes
Salinity is one of the major abiotic stresses that affects physiological processes of plants and reduces crop growth and yield. In order to study the effect of salinity stress on some physiological and agronomical traits of Thymus daenensis subsp. daenensis ecotypes and their classification, a factorial experiment was carried out using randomized complete block design with three replications in...
متن کاملCarbon isotopes and iodine concentrations in a Mississippi River delta core recording land use, sediment transport, and dam building in the river's drainage basin.
Sedimentary material from coastal and nearshore areas in the Mississippi Delta region are comprised of different organic carbon sources with diverse ages that require isotopic and elemental records for resolving the various sources of plant residues. Carbon isotopic ((13)C, (14)C) values were used to differentiate contributions from plants using the C3, C4, and/or CAM (crassulacean acid metabol...
متن کاملGenetic Diversity Evaluation of Lemon balm (Melissa officinalis L.) Ecotypes Using Morphological Traits and Molecular Markers
Genetic diversity of 12 lemon balm ecotypes was evaluated using agronomic traits as well as ISSR and RAPD markers. Results of analysis of variance showed high diversity among the studied ecotypes. Cluster analysis using UPGMA method grouped the ecotypes into three different groups based on the agronomic traits. Twelve ISSR primers created 106 polymorphic bands among the studied ecotypes. An ISS...
متن کاملThe landscape context of plant invasions in Mississippi wetlands
Invasive species are a known and growing threat to native ecosystems and the services they provide, and it is widely accepted that human activities contribute substantially to their spread. In a study of fifty-two north Mississippi wetlands, approximately 10% of the vascular plant species encountered were non-native, and 60% of the wetlands surveyed contained at least one plant species consider...
متن کاملAssessment of combining ability and comparison of selected selfed and open pollinated generations clones of alfalfa (Medicago sativa L.) ecotypes
This study was conducted to quantitatively evaluate selfed (S1, S2 and S3) and open pollinated (OP1, OP2 and OP3) generations of alfalfa in terms of inbreeding depression and general combining ability of S2 families of alfalfa ecotypes. Selfing of selected plants to produce three generations of S1, S2 and S3 generations were performed under the field conditions and the clones of each selfed- ge...
