Interpretive Summary:

Technical Abstract: Cotton leaf temperatures having leaf clip-cages had leaf temperatures under leaf cage rings 12% higher compared with leaf temperatures outside the leaf clip-cages. This probably occurred because of the pressure of the leaf clip cage rings on leaf tissues and the prevention of transpiration on the parts of leaf blades under the cage rings. Leaf blade temperatures adjacent to the edges of clip-cage rings and inside the cages were 9% and 6% higher, respectively, compared with temperatures outside leaf clip cage rings. A single leaf plant technique, with the stem terminal and all other leaves removed, was developed to evaluate the impact of silverleaf whitefly infestations on cotton leaf physiology. Silverleaf whitefly infestation- stressed plants had reduced photosynthesis and transpiration, and increased leaf temperatures under greenhouse conditions compared with uninfested plants.
