“…We performed analysis of available data on the structure of root-hemiparasitic Scrophs such as Rhinanthus, Melampyrum, Odontites species and others [10][11][12][13][14] in comparison with Thesium ebracteatum. Root-hemiparasitic Scrophs have leaves with hydathodes and trichomes [11][12][13], stems and roots with ring cambium [11,14] that produce additional xylem tissue BIO Web of Conferences 11, 00022 (2018) https://doi.org/10.1051/bioconf/20181100022 Prospects of Development and Challenges of Modern Botany embedded lignified xylem parenchyma and deficiently secondary phloem [10]. All roots hemiparasitic plants had haustorial connections, but we noticed that hemiparasitic Scrophs had significant differences from Thesium in leaves, roots and stems structure.…”
