Abstract

In this article, a particular attention is paid to the role of ethylene hormone in cherry tomatoes, from opening flowers to organic mature red fruits. We also assessed the effect of nitrogen flow on cherry tomatoes using a very sensitive laser photoacoustic spectroscopy system. The character of the determinations makes it possible to determine the emission sites of the gaseous plant hormone ethylene and its importance. In aerobic conditions, we monitored the evolution of ethylene concentration from flower to mature red fruit. The nitrogen flow increases the production of ethylene in green and mature cherry tomato fruits and stops the production of ethylene in flowers..
