The Influence of Reflective Mulches and Lettuce Types on the Incidence of Aster Yellows and Abundance of its Vector, \u3ci\u3eMacrosteles Fascifrons\u3c/i\u3e (Homoptera: Cicadelidae), in Minnesota [PDF]

open access: yes, 2017
Five commercial lettuce cultivars representing different genetic types were grown through aluminum-coated paper, through black polyethylene film, and on bare soil. For each variety, the aluminum mulch reduced the numbers of Macrosteles fascifrons (St~l),

Solar‐Driven Ammonia Synthesis From Nitrate Reduction Paired With CO2 Capture for Sustainable Agriculture via a Robust CuPd Heterojunction

open access: yesAngewandte Chemie, EarlyView.
Laser‐assisted synthesis of CuPd amorphous/crystalline heterojunction demonstrates >80% Faradaic efficiency for nitrate‐to‐ammonia electroreduction across wide potential windows. The integrated solar‐powered electrolyzer achieves 6% solar‐to‐ammonia energy efficiency at 0.4 sun, 6–20 mg h−1 CO2 capture rate, and stability exceeding 100 h.

Effects of hyperaccumulator plant straw on biomass and cadmium accumulation of lettuce [PDF]

open access: yesE3S Web of Conferences, 2019
To study the effects of hyper-accumulator plant straw on the biomass and cadmium (Cd) accumulation of lettuce (Lactuca sativa), the pot experiments were conducted to study the effects of straw application of three hyper-accumulator plants (Solanum nigrum,

The effect of within-crop habitat manipulations on the conservation biological control of aphids in field-grown lettuce [PDF]

open access: yes, 2011
Within-crop habitat manipulations have the potential to increase the biological control of pests in horticultural field crops. Wildflower strips have been shown to increase the abundance of natural enemies, but there is little evidence to date of an ...

Root-applied glycinebetaine controls nitrate content and edible quality of lettuce in continuous commercial hydroponic greenhouse production

open access: yesFrontiers in Sustainable Food Systems, 2023
Lettuce (Lactuca sativa L.) may accumulate high amounts of nitrate NO3− in hydroponic cultivation, such as in the Nutrient Film Technique (NFT) system.

Elucidating the genetic basis of antioxidant status in lettuce (Lactuca sativa). [PDF]

open access: yes, 2015
A diet rich in phytonutrients from fruit and vegetables has been acknowledged to afford protection against a range of human diseases, but many of the most popular vegetables are low in phytonutrients. Wild relatives of crops may contain allelic variation

The Effect of Head Lettuce (Lactuca sativa var. capitata L.) Cultivation Under Glass with a Light Spectrum-Modifying Luminophore on Crop Traits

open access: yesAgronomy
The present study aimed to evaluate crop characteristics, including morpho-anatomical features and nutritional and health-promoting composition, of head lettuce cultivated in greenhouses covered with transparent glass (control) and glass containing a red

Microbiological quality of lettuce (Lactuca sativa) consumed on the streets of Maroua (Cameroon: Effect of disinfecting agents used by some vendors [PDF]

open access: yes, 2017
This study was carried out to determine and compare the microbiological quality of lettuce (Lactuca sativa) from market (unwashed) and those ready to eat in Maroua. The results revealed that 92.3% of lettuce vendors in Maroua, used Chlorine and 7.7% used

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

open access: yesAdvanced Science, EarlyView.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.
