Article Figures & Data
Figures
- Figure 1.
Sap flow per unit leaf area of four cultivars of crape myrtle as affected by surface material.
- Figure 2.
Surface temperatures (A), air temperatures (B), and leaf-air vapor pressure deficits (C) as affected by surface material on 23 Aug. 1989. Only measurements replicated inthis figure were surface temperatures (A). Each point is the mean of five replications per surface treatment. Vertical bars represent SE of the mean. SE is smaller than symbol when error bar is not shown.
- Figure 3.
Daily water use of hibiscus plants in a control, uniconazole, and pruning treatment. Pruning was done on CDN 129. Vertical bars indicate average standard deviation (n=5). Arrows denote irrigations after 1600 h.
- Figure 4.
Midday pattern of leaf transpiration for hibiscus plants in control, uniconazole, and pruning treatments. Symbols represent the means from three or more plants and six or more measurements per treatment ±1 SD. Data were collected between 1300 and 1530 h.
