Two sweetpotato (Ipomoea batatas (L.) Lam) genotypes ('Georgia Jet' and the breeding clone TI-155) were grown at 12-, 15-, 18-, and 21-h light/12-, 9-, 6-, 3-h dark cycles, respectively, to evaluate their growth and elemental concentration responses to duration and amount of daily lighting. Vine cuttings (15 cm long) of both genotypes were grown in rectangular nutrient film technique channels for 120 days. Conditions were as follows: photosynthetic photon flux (PPF) mean 427 μmolm -2 •s -1… Expand
Physiological, Morphological Changes and Storage Root Yield of Sweetpotato [Ipomoea batatas (L.) Lam.] under PEG-Induced Water Stress
TLDR
Chlorophyll degradation, chlorophyll fluorescence diminution and stomatal closure were found in plants grown under PEG-induced water deficit conditions, leading to reduction in net photosynthetic rate and subsequently lesser amounts of glucose and fructose contents in the leaf tissues. Expand

TLDR
Investigation of the impact of microgravity on root growth, distribution of amyloplasts in the root cells, and on the concentration of soluble sugars and starch in the stems of sweetpotatoes suggests that the space flight environment did not adversely impact sweetpotato metabolism and that vegetative cuttings should be an acceptable approach for propagatingSweetpotato plants for space applications.

Relationship between vine propagation method, and growth and yield in sweetpotato[Ipomoea batatas(l.)lam]
TLDR
This study concluded that propagation method does not affect the development and yield of sweetpotato (p ≤ 0.05). Expand
Sweet potato production in a short-season area utilizing black plastic mulch: effects of cultivar, in-row plant spacing, and harvest date on yield parameters.
The sweet potato (Ipomoea batatas (L.) Lam.) requires a long, hot growing season to attain good yields. In a cool climate, the use of black plastic mulch to heat the soil can improve growth butExpand
The Combined Conditions of Photoperiod, Light Intensity, and Air Temperature Control the Growth and Development of Tomato and Red Pepper Seedlings in a Closed Transplant Production System

Effects of leaf aging and light duration on photosynthetic characteristics in a cucumber canopy
TLDR
Photosynthetic characteristics, chlorophyll index and leaf area were examined in selected leaves of cucumber and it was shown that the lower leaves have a significant reduction in photosynthetic capacity due to reduced light conditions. Expand

Reversibility of Photosynthetic Inhibition in Cotton after Long-Term Exposure to Elevated CO(2) Concentrations.
TLDR
The rapid and complete reversal of photosynthetic inhibition suggests that the appearance of large, strong sinks at certain developmental stages could result in reduction of the large starch accumulations and that photosynthesis rates could recover to near the theoretical capacity during periods of high photosynthate demand.

Plant Spacing Influences Yield and Linear Growth Rate of Sweetpotatoes Grown Hydroponically
TLDR
Storage root count, fresh and dry weights, and linear growth rate of sweetpotatoes grown by use of the nutrient film technique declined linearly in response to decreased BCS, while fresh anddry foliage weight decreased linearly and quadratically as spacing was reduced within the growth channels.

TLDR
There are serious limitations to the use of NFT alone for growth of potatoes in a CELSS system, and these can be minimized by using a modified NFT with a shallow layer of media, such as arcillite, yet additional work is needed to ensure high tuber production with this system under long photoperiods.
