Short-Term And Long-Term Time Course Studies Of Turmeric (Curcuma Longa L.) Microrhizome Development In Vitro, Jeffrey Adelberg, Matthew M. Cousins Jul 2014

Short-Term And Long-Term Time Course Studies Of Turmeric (Curcuma Longa L.) Microrhizome Development In Vitro, Jeffrey Adelberg, Matthew M. Cousins

Jeffrey W Adelberg

Turmeric (Curcuma longa L.) plantlets were cultured in MS (Murashige and Skoog Physiol Plant 15:473–497, 1962) liquid medium with 6% sucrose. Microrhizome development was observed in the presence of methyl jasmonate (MeJa) (0, 5 and 16 μM) and benzyladenine (BA) (0, 0.32 and 1 μM). Leaf, root, rhizome growth, and sugar use were measured weekly for 6 weeks in small vessels (180 ml) and four times in 23 weeks in larger vessels (2.5 l). MeJa reduced leaf, root, and rhizome biomass. BA had a positive effect on biomass accumulation. Microrhizome mass increased at a linear rate during 6 weeks of …


Opportunities For Energy Crop Production Based On Subfield Scale Distribution Of Profitability, Ian J. Bonner, Kara G. Cafferty, David J. Muth, Mark D. Tomer, David E. James, Sarah A. Porter, Douglas L. Karlen Jan 2014

Opportunities For Energy Crop Production Based On Subfield Scale Distribution Of Profitability, Ian J. Bonner, Kara G. Cafferty, David J. Muth, Mark D. Tomer, David E. James, Sarah A. Porter, Douglas L. Karlen

David J. Muth

Incorporation of dedicated herbaceous energy crops into row crop landscapes is a promising means to supply an expanding biofuel industry while benefiting soil and water quality and increasing biodiversity. Despite these positive traits, energy crops remain largely unaccepted due to concerns over their practicality and cost of implementation. This paper presents a case study for Hardin County, Iowa, to demonstrate how subfield decision making can be used to target candidate areas for conversion to energy crop production. Estimates of variability in row crop production at a subfield level are used to model the economic performance of corn (Zea mays L.) …
