Cotton growth, development, and yield when utilizing ThryvOn under high thrips pressure

Joshua M. Lee, John L. Snider, Phillip M. Roberts, Lavesta C. Hand et autres

Abstract Thrips (Thysanoptera: Thripidae) are consistent pests in cotton ( Gossypium hirsutum ) production during the early season. In addition to cultural and chemical practices for thrips management, a new Bt ( Bacillus thuringiensis ) trait called ThryvOn is available for thrips …

Impacts of wide row spacings on yield and yield components of upland cotton ( Gossypium hirsutum L.)

Caitlyn B. Lawton, John L. Snider, Peng Wah Chee, Sarah T. Hobby et autres

Abstract This study quantifies the effects of wide row spacing on lint yield, yield components, and fiber quality of upland cotton ( Gossypium hirsutum L.). An experiment was conducted in Tifton, GA in 2021 and 2022, where cotton was planted in six …

Diffusional and Biochemical Limitations to Photosynthesis Under Water Deficit for Field‐Grown Cotton

Ved Parkash, John L. Snider, Gurpreet K. Virk, Kamalpreet Kaur Dhillon et autres

Abstract Water deficit stress limits net photosynthetic rate (AN), but the relative sensitivities of underlying processes such as thylakoid reactions, ATP production, carbon fixation reactions, and carbon loss processes to water deficit stress in field‐grown upland cotton require further exploration. Therefore, the …

Estimating yield-contributing physiological parameters of cotton using UAV-based imagery

Amrit Pokhrel, Simerjeet Singh Virk, John L. Snider, George Vellidis et autres

Lint yield in cotton is governed by light intercepted by the canopy (IPAR), radiation use efficiency (RUE), and harvest index (HI). However, the conventional methods of measuring these yield-governing physiological parameters are labor-intensive, time-consuming and requires destructive sampling. This study aimed to …

Effect of irrigation termination times on cotton cultivars with contrasting maturities

Bailey Lawson, John L. Snider, Lavesta C. Hand, Wesley M. Porter et autres

Abstract Optimizing irrigation termination time can save water and preserve lint yield and fiber quality in cotton. Although there is currently an irrigation termination recommendation in Georgia, the ideal time for termination could be influenced by cultivar differences in maturity. The hypotheses …

Stereoselectivity in (Acyloxy)borane-Catalyzed Mukaiyama Aldol Reactions

Joshua M. Lee, Xin Zhang, Per‐Ola Norrby, Paul M. Helquist et autres

The origin of diastereo- and enantioselectivity in a Lewis acid-catalyzed Mukaiyama aldol reaction is investigated using a combination of dispersion corrected DFT calculations and transition state force fields (TSFF) developed using the quantum guided molecular mechanics (Q2MM) method. The reaction proceeds via …

Internal and External Stereoisomers of Squaraine Rotaxane Endoperoxide: Synthesis, Chemical Differences, and Structural Revision

Carleton G. Collins, Joshua M. Lee, Allen G. Oliver, Olaf Wiest et autres

Photooxygenation of permanently interlocked squaraine rotaxanes with anthracene-containing macrocycles produces the corresponding squaraine rotaxane endoperoxides (SREPs) quantitatively. SREPs are stored at low temperature, and upon warming, they undergo clean cycloreversion, releasing singlet oxygen and emitting light. The structural elucidation in 2010 assigned …
