- ... Numerous techniques are currently available for meassurement of plant water status in field environments, including pressure chambers and indices based upon infrared-determined canopy temperatures. The Campbell-Brewster (J-14) leaf press has been promoted as a compact alternative to the pressure chamber for plant water potential determination. In-depth comparisons of the J-14 (.PSI.J) with the pre ...

- ... One striking characteristic of red clover (Trifolium pratense L.) is the reflective band across the mid-region of the leaves of many plants. The objective of this study was to determine the nature of this band as related to potential ecological significance. A radiation budget was determined for the light and dark green regions under mid-day sunlight using measurements made with a Li-Cor, LI-1800 ...
