High temperature stress responses of Salvia splendens and Viola X wittrockiana
… growth and development of bedding plants is high temperature stress. The deleterious effects of high temperature stress are the most pronounced during plug transplant and/or during the transition period from the nursery to the landscape. High temperature stress responses were investigated in …

Accelerated thermal degradation testing of GAN HEMTs under high-temperature stress
Gallium Nitride (GaN) high-electron-mobility transistors (HEMTs) are having increased applications in high-power and high-frequency conversion areas due to their superior switching speed, high breakdown voltage, and low conduction losses. Despite their advantages, GaN HEMTs are prone to performance …

The influence of high temperature stress and herbicides on the susceptibility of creeping bentgrass (Agrostis palustris) to Curvularia lunata
… of C. lunata in vitro were determined. 2) Acute high temperature stress was evaluated as a predisposing factor in the susceptibility of creeping bentgrass to C. lunata. 3) The effects of acute high temperature stress and exposure to five different herbicides on creeping bentgrass were evaluated …

Heat Stress Effects on Cotton During Reproductive Development and Subsequent Acclimation Responses
<p>High temperature stress is among the most difficult to control abiotic factors affecting crop yields in the Southern United States due to its wide regional influence. Cotton (Gossypium hirsutum L.) though a tropical plant in origin, it is sensitive to the effects of high temperature. This is of …

Cytokinin-mediated processes promote heat-induced disease susceptibility of plants to bacterial pathogens
As global human populations continue to grow and temperatures are expected to rise, the pressure to increase food productivity and develop more stress-resistant crop varieties intensifies. Increased temperatures, a consequence anticipated as a result of global climate change, is expected to have an …
