The plant hormone ethylene is involved in many plant processes ranging from seed germination to leaf and flower senescence and fruit ripening. Ethylene is synthesized from methionine, via S-adenosyl-L-methionine (SAM) and 1-amino- cyclopropane-1-carboxylic acid (ACC). The key ethylene biosynthetic enzymes are ACC synthase (ACS) and ACC oxidase (ACO). Manipulation of ethylene biosynthesis by chemicals and gene technology is discussed. Biotechnological modification of ethylene synthesis is a promising method to prevent spoilage of agricultural and horticultural products.

Microcuttings of easy-to-root dwarf rose cv. Starina, showing early symptoms of leaf senescence and shoot-tip necrosis in rooting stage, were chosen for the study. The effects of inhibitors of ethylene biosynthesis (AOA, AIB) and action (AgNO₃), and Ca²⁺ and Mg²⁺ were studied in relation to rooting, leaf senescence and shoot-tip necrosis. The effects of these substances were examined with respect to IAA presence in a medium, which stimulated leaf yellowing and shoot-tip necrosis. AOA strongly inhibited rooting of microcuttings, but did not affect ethylene biosynthesis. AIB at 250 mg·l⁻¹ and AgNO₃ 2.5 mg·l⁻¹ in the presence of IAA did not affect rooting but effectively prevented leaf senescence. Ca²⁺ alone or combined with Mg²⁺ at raised concentration, or an ethylene action inhibitor Ag⁺, reduced shoot-tip necrosis in microcuttings treated with IAA. Addition of Ag⁺ to IAA medium drastically increased ethylene production by the shoots. Interaction between endogenous levels of auxin, ethylene and calcium in relation to rooting, shoot-tip necrosis and leaf senescence was discussed. Ethylene could enhance tissue sensitivity to auxin. Moreover, the tissue of rose shoots is very sensitive in the in vitro condition on standard medium because of the calcium deficiency. Thus, the raised Ca/Mg level counteracted shoot-tip necrosis through enhancing cell membrane and wall resistance to ethylene and IAA.
