Environmental modification of yield and food composition of cowpea and leaf lettuce
Author(s): Mitchell, Cary A.; Nielsen, Suzanne S.; Bubenheim, David L.
Abstract: Cowpea (Vigna unguiculata (L.) Walp.) and leaf lettuce (Lactuca sativa L.) are candidate species to provide ligume protein and starch or serve as a salad base for a nutritionally balanced and psychologically satisfying ...

Accession Number: 91N31777; Document ID: 19910022463
Candidate species selection for a controlled ecological life-support system
Author(s): Mitchell, Cary A.
Abstract: NASA Ames Cooperative Agreement NCC 2-100 was a project funded in the biomass production group of the NASA Controlled Ecological Life-Support System (CELSS) Program. The early years of the project emphasized the use of leaf ...
NASA Center: NASA (non Center Specific) Publication Year: 1990
Added to NTRS: 2005-08-25

Optimizing environmental conditions for mass application of mechano-dwarfing stimuli to Arabidopsis
Author(s): Montgomery, Jill A.; Bressan, Ray A.; Mitchell, Cary A.
Abstract: Obtaining uniform mechano-dwarfing of Arabidopsis thaliana (L.) Heynh. seedlings within dense plantings is problematic. Alternative forms of mechano-stimulation were applied to seedlings in effort to obtain uniform growth ...

Minitron II system for precise control of the plant growth environment
Author(s): Knight, Sharon L.; Akers, Carolyn P.; Akers, S. W.; Mitchell, Cary A.
Abstract: The Minitron II system which accommodates hydroponic culture and separate control of atmospheric composition in individual chambers is used to measure gas-exchange by small crop canopies in the undisturbed plant growth ...

Modification of yield and chlorophyll content in leaf lettuce by HPS radiation and nitrogen treatments
Author(s): Mitchell, Cary A.; Leakakos, Tina; Ford, Tameria L.
Abstract: The potential of realizing high photosynthetic photon flux from radiation by high-pressure sodium (HPS) lamp, alone or in combination with metal halide (MH) plus quartz iodide (QI) incandescent lamps, to support lettuce ...

Stimulation of lettuce productivity by manipulation of diurnal temperature and light
Author(s): Knight, Sharon L.; Mitchell, Cary A.
Abstract: Salad Bowl and Waldmann's Green leaf lettuce (Lactuca sativa L.) were exposed to photosynthetic photon flux densities (PPFDs) of 444 or 889 micromol/s per sq m for 20 hrs/day under a diurnal temperature regime of 25-C ...

Effects of incandescent radiation on photosynthesis, growth rate and yield of 'Waldmann's Green' leaf lettuce
Author(s): Knight, Sharon L.; Mitchell, Cary A.
Abstract: Effects of different ratios of incandescent (ln) to fluorescent (Fl) radiation were tested on growth of 'Waldmann's Green' leaf lettuce in a controlled environment. After 4 days of treatment, dry weight, leaf area, relative ...

Growth and yield characteristics of 'Waldmann's Green' leaf lettuce under different photon fluxes from metal halide or incandescent fluorescent radiation
Author(s): Knight, Sharon L.; Mitchell, Cary A.
Abstract: Growth of 'Waldmann's Green' leaf lettuce under metal halide radiation was compared with that under In = Fl at the same photosynthetic photon flux (920 micromol/s/sq m) to evaluate the influence of lamp type on growth. No ...
