TAILIEUCHUNG - Anatomical structures of vegetative and reproductive organs of Senna occidentalis (Caesalpiniaceae)

The current investigation is concerned with the histological features of Senna occidentalis (L.) Link (coffee senna plant). The anatomical structure of different vegetative and reproductive organs was investigated weekly or fortnightly, according to the investigated organ, throughout the growing season. | Turkish Journal of Botany Research Article Turk J Bot (2013) 37: 542-552 © TÜBİTAK doi: Anatomical structures of vegetative and reproductive organs of Senna occidentalis (Caesalpiniaceae) Mohamed Abdel Aziz Ahmed NASSAR, Hassan Ramadan Hassan RAMADAN, Hend Mohammad Saad IBRAHIM* Department of Agricultural Botany, Faculty of Agriculture, Cairo University, Gamaa St., Giza, Egypt Received: Accepted: Published Online: Printed: Abstract: The current investigation is concerned with the histological features of Senna occidentalis (L.) Link (coffee senna plant). The anatomical structure of different vegetative and reproductive organs was investigated weekly or fortnightly, according to the investigated organ, throughout the growing season. Organs studied included the main root, main stem (represented by shoot apex, apical, and median internodes), different foliage leaves developed on the main stem and on lateral shoots (including lamina and petiole), epidermal peel and trichomes, flower buds, fruits, and seeds. Histological features of various organs of the coffee senna plant were analysed microscopically and photomicrographed. Moreover, ultrastructural features of the seed coat were investigated by scanning electron microscope. Key words: Senna, Caesalpiniaceae, anatomy, vegetative organs, reproductive organs 1. Introduction Senna occidentalis (L.) Link, commonly known as coffee senna, is typically a shrub native to America that is widespread in warm areas of the world, except for Australasia. Coffee senna is used as a flowering shrub for landscape purposes (Hussein, 2003). It is also used as a coffee substitute and has some medicinal uses. When seeds are brewed into the coffee-like beverage it is used to treat asthma. Previous pharmacological investigations showed that Senna occidentalis leaf extracts have broad spectrum antibacterial, antimalarial, antifungal .
