After the indicated interval of time the explants were temporarily removed from the chamber and petioles that fell off with a gentle touch were recorded as abscised. To check for ethylene-induced chlorosis in healthy recently expanded trifoliate leaves, excised leaves were placed on moist paper towels in a dark chamber at 23[degrees]C, the air was brought to 10 [micro]L [L.sup.-1] ethylene by injection with a known amount of pure ethylene, and leaves were then visually checked for signs of chlorosis at the indicated number of days after start of the ethylene treatment.
