- Аннотация: Gromenko I.S., Lotova L.I. COMPARATIVE ANATOMY OF FRUITS IN REPRESENTATIVES OF MALOIDEAE (ROSACEAE). Syncarpous and hemisyncarpous gynoecia are revealed in both tribes investigated. Pseudoapocarpous gynoecium is also revealed in some representatives of the tribe Crataegeae. All investigated species have indistinctive anatomical zones in their fruits. In tribe Crataegeae, the pulp must have come from the hypanthium tissues and the putamen must be homologous with the whole pericarpium of Maleae species. However, the outer tissue of the putamen could have derived from the inner tissue of hypanthium. In tribe Maleae, the pulp is a complex derivative of hypanthium and carpel tissues, though the inner tissues of the carpels are lignified in few representatives of the tribe (Malus sp., Sorbus aucuparia etc.). The fruits in both tribes initially grow diffusely by means of multidirectional divisions of their cells (anticlinal cell divisions prevail in the epidermis). The fruits grow by means of pulp cell growth after the fruit cells have ceased dividing. The fruits of intergeneric hybrids are anatomically similar with those of either parent. The gynoecim type, characters of epidermal and hypodermal cells, presence of sclereids and phlobaphen-bearing cells and their disposition are all of diagnostic value. Mespilus germanica differs from other representatives of tribe Crataegeae in some anatomical traits of its fruits.
