Tomato ripening in normal red-fruited cultivar (Fiorin) was delayed by treatment with methyl jasmonate (JA-Me) vapour. A visual scoring system for describing tomato ripening was used. Surface of fruits exposed to JA-Me vapour, increased in yellow and decreased in red as determined by HunterLab colour meter. JA-Me significantly altered the firmness of fruits after 21 days storage. Vapour of JA-Me enhanced the level of β-carotene in outer part (peel with 3 mm pericarp tissue) of fruit, while it had no effect in peeled fruit pericarp. JA-Me treatment decreased the level of lycopene in outer part and pericarp tissue, however, in outer part lycopene content decreased at a higher rate than in pericarp. Amount of tomatine in fruits treated with JA-Me had enhanced four-fold in outer part and by 62% in peeled fruit pericarp as compared with the control.

Β Carotene

Fruit of the rin tomato (Lycopersicon esculentum Mill.) mutant were analyzed for chlorophyll and carotenoid composition. Thirty days after pollination, rin fruit contained less chlorophyll a and more chlorophyll b, causing a lower a:b ratio than fruit of the normal ripening line. Phytoene, phytofluene, β-carotene, γ-carotene, and lycopene were all present in normal fruit 40–45 days old. In contrast, the carotenoids found in rin fruit were composed mostly of phytoene, with reduced quantities of β- and γ-carotene and traces of phytofluene and lycopene. Fruits of rin contained only phytoene and β-carotene after 180 days. These changes in endogenous pigments are interpreted as pleiotropic effects of the rin gene on the ripening tomato fruit. Pigmentation differences in fruit of the reciprocal hybrids were detected.
