Fig. 1. Induction of CAM in M. crystallinum by abscisic acid polyethylene glycol and NaCl. After 5 weeks of growth in soil (day zero), plants were watered daily with nutrient media (control), or nutrient media containing 10 JM ABA, 15% PEG, or 0.35 M NaCl. The acidity and malate content of leaf extracts were measured after the sixth day.

Fig. 7.1. (A) Time course of a-amylase release by 10 aleurone layers of Himalaya barley incubated with 1 iM GA. Enzyme activity measured in the medium surrounding the aleurone layers and in the supernatant of a 0.2 M NaCl extract of the aleurone layers. Total refers to the sum of these two activities. After Chrispeels and Varner, 1967 [22]. (B) Midcourse inhibition of a-amylase production and release by abscisic acid and cycloheximide. Aleurone layers were incubated in 0.1 pM GA for 11 h and then 5 pM abscisic acid or lOpg/ml cycloheximide was added (arrowed). After Chrisppels and Varner, 1967 [23]...
