Regulation of water flow in an interconnected xylem vessel network enables plants to survive despite challenging environment changes that can cause xylem embolism. In this study, vulnerability to embolisms of xylem vessels and their water-refilling patterns in vascular bundles of maize leaves were experimentally investigated by employing synchrotron X-ray micro-imaging technique. A vascular bun...

The Lie derivation of multivector fields along multivector fields has been introduced by Schouten (see cite{Sc, S}), and studdied for example in cite{M} and cite{I}. In the present paper we define the Lie derivation of differential forms along multivector fields, and we extend this concept to covariant derivation on tangent bundles and vector bundles, and find natural relations between them and...

Angioleiomyomas that present with no symptoms are extremely rare, except when located on the head and neck. 1 Three cutaneous variants of this tumor have been described: piloleiomyoma, which originates in the erector pili muscle; angioleiomyoma, which originates in the smooth muscle of blood vessel walls; and genital leiomyoma, which originates in the smooth muscle of the scrotum, vulva, or nip...

In this study, the vegetative anatomy of Artemisia umbelliformis subsp. eriantha, a Central European alpine glacial relict, wild-growing on Mt. Durmitor (Montenegro) was examined for first time. The aim to investigate general and particular anatomical traits which might have possible taxonomic value. Microscopic slides were prepared according standard histological procedures. adventitious young...

White turmeric has underground stems that develop rhizomes. It been used as an Eastern traditional herb for a long time. As with many other monocotyledons, the growth of white is mainly due to presence primary thickening meristem. Currently, study meristem, radial growth, and accumulation secondary material essential oil in rhizomes, including turmeric, still limited. In this study, we observed...
