Diplotaxis tenuifolia (Brassicaceae) üzerine morfolojik, anatomik, palinolojik ve mikromorfolojik bir araştırma

Abstract

Bu çalışmada Diplotaxis tenuifolia türünün morfolojik, anatomik, palinolojik ve mikromorfolojik özellikleri ele alınmaktadır. Gövde enine kesitleri, tek tabakalı epidermis, parankimatik korteks, iletim demetleri ve öz hücrelerini içermektedir. Yapraklarda, çok tabakalı palizat parankimalı ekvifasiyal tip mezofil gözlemlenmiş, fakat sünger parankiması indirgenmiştir. İletim demetleri orta damar hariç küçüktür. Meyve enine kesitleri tek bir ekzokarp, 3 ya da 4 tabakalı mezokarp ve tek tabakalı endokarpa sahiptir. Tohum enine kesitleri, epidermis, parankima ve endosperm tabakalarının varlığını göstermiştir.

Morphological, anatomical, palynological, and micromorphological study on Diplotaxis tenuifolia (Brassicaceae)

Abstract

The present study deals with the morphological, anatomical, and palynological properties of Diplotaxis tenuifolia. The stem cross-sections had a single-layered epidermis, parenchymatous cortex, vascular bundles, and parenchymatic pith cells. An equifacial mesophyll type was observed in the leaves with multiple-layered palisade tissue, but the spongy parenchyma was reduced. Vascular bundles were small except for the midrib. The cross-sections of the fruit had a single exocarp, 3- or 4-layered mesocarp, and single-layered endocarp. Transverse sections of the seed showed the presence of layers of epidermis, parenchyma, and endosperm.
