Factors Influencing Adventitious Root Formation Of Floral Hemp In Propagation, Alexandra Carver

All Theses

Commercial propagators have reported relatively poor propagation success, e.g., <75% rooting, for many hemp (Cannabis sativa) cultivars. These rooting percentages have a significant economic impact due to the wasted labor, space and supplies. Also, the market demands 100% of the propagation cells in a tray to be fully rooted, thus repairing and replacing poorly rooted or unrooted cuttings requires significant labor cost. The goal of this thesis was to evaluate several factors that influence adventitious root formation of hemp stem cuttings.

Chapter 2 describes an experiment conducted to identify rooting hormone treatments that could improve propagation success. Sixteen combinations of indole-3-butyric acid (IBA; 0, …

I’M A Forest, Not A Saltmarsh, Captain: Carbon And Sap Flow Dynamics In Coastal Forested Wetlands Of The Southeastern United States, Chris Shipway

All Theses

Coastal forested wetlands are identified as some of the highest-priority ecosystems for climate change mitigation. Here, we present two studies conducted in these unique ecosystems.

The first assessed changes in aboveground vegetative C stocks along the estuarine-riverine gradients of the Winyah Bay in South Carolina and the Savannah River in Georgia, using a space-for-time substitution to increase understanding of the impacts to upper estuarine forested wetlands from relative sea level rise. Standing C stocks on the Savannah River averaged 183.6 Mg C ha^-1, while sites on the Winyah system averaged 162.3 Mg C ha^-1. The largest …

Changes In Soil Chemical Attributes, Horticultural Performance And Fruit Yield Of Peach Cultivars Following Preplant And Annual Applications Of Composted Mulch Amendments, Jeffrey Hopkins

All Theses

Southeastern peach orchards often have poor soil quality due to native soil composition, intensive farming practices and generational replanting of trees in the same locations. This study investigated using mulch amendments to improve the chemical and physical quality of soil prior to planting a new peach orchard. At the beginning of the four-year study, a single-ground municipal composted mulch was incorporated into the soil at two different rates and three cultivars of peaches, ‘Rubyprince’, ‘Julyprince’, and ‘BigRed’ were planted on berms. Thereafter, the same mulch product was annually applied to the top of the berms at two different rates to …

Yield And Nutritive Quality Of Fresh And Ensiled Reduced Lignin Alfalfa In Monoculture And Diculture With Novel Tall Fescue, Morgan Boss

All Theses

The objectives of this research were to: (1) evaluate the yield, nutritional value, and digestibility of fresh and ensiled reduced lignin alfalfa (RLA; Medicago sativa L.) in monoculture and when mixed with novel endophyte-infected tall fescue (F; Festuca arundinacea) in comparison to a conventional alfalfa (CA) cultivar; and (2) evaluate ensiled samples under varying DM concentrations; with or without inoculant. A trial was prepared as a randomized complete block design with 4 replicates per treatment. Treatments included reduced lignin alfalfa (RLA), conventional alfalfa (CA) and tall fescue (F) plots as well as RLA/F and CA/F plots. Plots were harvested on …
