“…How-ever, stomata may also be distributed on other parts, such as stems and floral organs, including petals, sepals, and spathes. Some of them participate in transpiration whereas others have no apparent function (Carpenter and Rasmussen, 1974;Elibox and Umaharan, 2010;Huang et al, 2018;Zhang et al, 2018;Zieli nski et al, 2010). Our recent work indicated that stomata are widely distributed on the petals, sepals, and stem surface of cut gerberas, and the stomata in the lower epidermis of the sepals play a critical role in postharvest water loss (Huang et al, 2018).…”

Leaf stomata are the main channels for water loss of plants including cut flowers. In this study, we investigated the organographic distribution, morphological characteristics, light–dark response, and water loss contribution of stomata in cut carnations (Dianthus caryophyllus L. ‘Master’), which are prone to typical water deficits despite a few and small leaves. Stomata were observed in the upper and lower leaf epidermis, stem surface, abaxial bract epidermis, and abaxial sepal epidermis. Stomatal density (SD) on the stem surface was the highest and significantly greater than that on the upper and lower leaf and abaxial bract epidermis. The sepal epidermis had the lowest SD and the smallest stomata whereas the upper leaf epidermis had the largest stomata. Changes in the water loss rate increased in the light and decreased in the dark in both intact and leaves-removed cut carnations. The water loss rate of the former was greater than that of the latter. However, the water loss rate for the stem-only cut carnations had weak change rhythms and was much lower than that for the intact and leaves-removed cut carnations. These findings demonstrate the differential contributions of stomata in leaves, stems, and floral organs to water loss, and help to elucidate further the mechanism underlying postharvest water deficit in cut carnations.

“…Until now stomata have been noted occasionally on seeds and fruits in a number of unrelated genera (Bergman, 1920;Jernstedt and Clark, 1979;Rugenstein and Lersten 1981). Stomata on achenes are also a characteristic feature of almost all species of Rosa, but their taxonomic value within this genus is rather limited (Zieliński et al, 2010).…”

“…With reference to Paiva et al (2006), stomata present on seeds may be involved in water intake during the first phase of seed germination. According to Zieliński and Tomaszewski (2010), who described the presence of stomata on the pericarp of roses, a similar explanation is difficult to accept as the pericarp is thick and the cells are strongly lignified. The endocarps of Myrsinoideae also consist of thick-walled and strongly lignified cells, while the observed stomata, similarly as those in Jacquinia fruits, were located in places with no access to light.…”

Comparative micromorphology and anatomy of seeds and endocarps of selected Primulaceae and their systematic implications

Seed and endocarp micromorphology and anatomy of 16 taxa from the genera Ardisia, Geissanthus, Stylogyne, Myrsine (Myrsinoideae), and Jacquinia (Theophrastoideae) were examined using stereo-and scanning electron microscopy and discussed in the light of the current phylogenetic framework. In all species, the ornamentation of the seed surface was reticulate, tuberculate, or tuberculate-colliculate with several differences concerning the cell outline and anticlinal cell wall boundaries. For seeds of almost all Myrsinoideae species, one-layered seed coat devoid of rhomboid or prismatic crystals was characteristic, while seeds of J. armillaris had a two-layered seed coat with prismatic crystals. The one-layered seed coat in Myrsinoideae may be considered a synapomorphy of this subfamily. The endosperm tissue in seeds of Myrsinoideae was differentiated into two types. Seeds of Ardisia and Geissanthus species were characterized by 'pitted' endosperm, while in seeds of Myrsine species both the 'pitted' endosperm and endosperm with evenly thickened cell walls were present. In seeds of Theophrastoideae, the endosperm was 'pitted.' Our results confirmed that the concave hilum area is characteristic of subglobose seeds of Myrsinoideae. The ruminate endosperm was present in all the examined Myrsine species, but it was absent in Ardisia crenata, Geissanthus ambiguus, and Stylogyne pauciflora seeds. Thus, the ruminate endosperm is not the feature clearly distinguishing the seeds of Myrsinoideae and Theophrastoideae. Endocarps of Myrsinoideae vary in terms of their morphology and anatomy. The variation within the primary and secondary sculpture of their inner surface and the presence of stomata in endocarps of particular species may have systematic implications.
