Locular pressure was monitored during ripening of tomato (Lycopersicon esculentum Mill.) fruit and the anatomy of the endocarp surface examined using scanning electron microscopy. The manometric pressure of the locule tissue increased from 0 in mature-green fruit to 10 to 50 Pa at the turning or pink stages, and then subsided in ripe fruit. Nonclimacteric fruit containing the ripening inhibitor (rin) mutation showed a similar pattern of internal pressure accumulation during senescence. Build-up of locular tissue pressure occurred in fruit ripening, on or off the plant, as well as in fruit with different susceptibility to cuticle cracking. Apertures ranging from 18-31 mum in width and 33-41 mum in length, with densities ranging from 6.7 to 47.9 apertures . mm(-2) were observed in the endocarp of mature-green fruit. These apertures were progressively occluded during early ripening and were absent in late ripening fruit. Aperture occlusion might result in reduced gas exchange between the locule and external fruit atmosphere, resulting in modification of the locular gas composition.
