Cyanide Determination in Root and Leaf Tissues.
(A) Two-week-old seedlings grown on vertical MS medium were collected and root and leaf tissues were assayed for cyanide content.
(B) Whole 2-week-old seedlings grown on vertical MS medium in the absence or presence of 10, 25, or 50 μM ACC were also collected and their cyanide content was determined. Values are means ± sd of three independent experiments. ***P < 0.001.
