fresh weight (FW), using its measurable morphological traits, is useful for a wide variety of purposes in pea shoot production. For example, it could potentially be used for robotic harvesting in identifying and selecting the proper target shoots with
homeobox fusion transcript ( Chen et al., 1997 ) in Mouse ear ( Me ) tomato ( Lycopersicon esculentum Mill.) can alter the morphology of wild-type tomato grafted on Me . We are intrigued about the consequences of this phenomenon in horticultural crops

lack of clearly definable morphological characters and the presence of great variability ( Davis and Barnett, 1997 ). Delimitation of species has been mainly based on leaf characteristics (color, width, and vernation), flowering time, the number of
Abstract
Many events in the ripening of fruit have received intensive study, yet we have little information on some of the structural changes involved. It is of value to summarize the current morphological information in the field of fruit ripening so that it may be considered in relation to the other contributions to this symposium. Not only is attention given here to structure during ripening, but some biochemical and physiological data in which structural changes are strongly implicated are considered. Our attention is limited to studies on the ripening of fleshy horticultural fruits; however, the phenomena considered may apply to other types of fruits or to other plant parts and tissues.
