“…However, the size of successive flowers increases along the inflorescences of some taxa (e.g. Arabidopsis (Brassicaceae), [10]; Narcissus (Amaryllidaceae), [11]), a pattern inconsistent with this hypothesis. Moreover, if proximal to distal decline were a general feature of inflorescences, such variation should affect the sizes of all organs of each flower, but this is often not the case.…”

“…At the same time, flower morphology and functionality are dependent upon the ontogenetic development, which was described by Diggle (1997). Notably, the eggplant is characterised by flower heteromorphology, abundant flowering and frequent dropping of flowers or fruitlets.…”

Caruso G., Pokluda R., Sekara A., Kalisz A., Jezdinský A., Kopta T., Grabowska A. (2017): Agricultural practices, biology and quality of eggplant cultivated in Central Europe. A review. Hort. Sci. (Prague), 44: 201-212.The eggplant is a warm-climate crop of high economic importance. In many Asian and Mediterranean countries, eggplants are essential components of everyday dishes, while in Central Europe they have become popular only in recent years. Eggplants are harvested at an immature stage and have low storage value; therefore, the sale of fruits in local markets requires an appropriate production strategy. In Poland, consumer demand for eggplants is currently met by imports and domestic production, which, until recently, has been carried out only in greenhouses, ensuring the availability of fresh fruits but resulting in high selling prices. The demand for eggplants is growing among Polish consumers, and, accordingly, field production is expected to gradually gain in importance due to the fruit's profitability. Accordingly, the biology and farming practices of this warm-climate crop remain in the investigation phase in temperate climate. This review aims to report the status of current knowledge regarding the technologies affecting the biology, cultivation, and nutritional value of eggplant grown in temperate climatic zone.

“…Those experiments designed specifically to discriminate between plasticity and 'metamorphosis' demonstrated that some part of the variation routinely attributed to plasticity of resource allocation was, in fact, due to inherent differences among flowers and fruits within inflorescence axes. While such variation falls within the definition of metamorphosis, I have termed the inherent variation within axes 'architectural effects' in recognition of the association of this variation with the position of the flower, fruit, or other structures within the overall architecture of a plant (Diggle, 1995(Diggle, , 1997b(Diggle, , 2002). …”

“…The pattern of intra-inflorescence variation produced by plasticity and by 'metamorphosis' may be identical, and only careful experimentation can reveal the actual source of morphological or functional variation. Perhaps even more significant to the study of plasticity, similar experiments with Arabidopsis thaliana (Brassicaceae) have demonstrated that architectural effects may not only mimic plasticity, as for example in S. hirtum and F. virginiana but may mask the true magnitude of plasticity, and/or cause misinterpretation of the direction of plasticity (Diggle, 1997b).…”

“…If plant biologists wish to understand 'the adaptive domain' and 'functional limits' of differentiation, metamorphosis, and plasticity, we must be cognizant of the potential to confound these phenomena and, when studying plasticity, use carefully designed experiments that control for developmental, and ontogenetic/architectural effects (e.g., Macnair and Cumbes, 1990;Wolfe, 1992;Diggle 1991aDiggle , 1995Diggle , 1997bMossop et al, 1994;Winn 1996;Mazer and Delesalle, 1996;Ashman and Hitchens, 2000). Plasticity and metamorphosis likely interact or overlap to produce the range of intra-individual phenotypic variation observed among plants.…”

Abstract. This series of essays addresses plasticity from the perspective of developmental morphology. The first essay deals with the problem of distinguishing between plasticity and other types of ontogenetic variation. In a temporally varying environment, morphological plasticity may be expressed as the production of a succession of different metamers. However, even in a constant environment, plant metamers can vary dramatically, a phenomenon known as heteroblasty. Because heteroblasty and plasticity can yield similar patterns of ontogenetic variation, the two are often confounded in analyses of developmental plasticity. The second essay discusses the integration of plant phenotypic responses and finds that the evidence for integration is equivocal. The third section shows that developmental properties can constrain the expression of morphological plasticity. Developmental lags and the 'epiphenotype problem' are particularly important features for analyses of the evolution and expression of plasticity. Finally, in answer to the question of strategies for studying plasticity, I emphasize the need for research at multiple levels and for the inclusion of a historical or phylogenetic perspective.
