Morphological and anatomical study on Galanthus gracilis (Amaryllidaceae)

Galanthus gracilis Čelak ranks among the finest snowdrops for garden and there are a number of excellent variants available from specialist bulb nurseries. Gracilines, a subgroup of the Amaryllidaceae alkaloids was isolated from Galanthus gracilis of Turkish origin. The galanthamin alkaloid which is isolated from the bulbs of Galanthus species is used in the physical therapy for poliomyelitis and in the treatment of same vascular diseases will be useful in pharmacy in Turkey.In this study, morphological and anatomical properties of Galanthus gracilis were investigated. Outer surface of inner perianth segments with green patches at apex and base is characteristics for Galanthus gracilis . Cross-sections of the root, scape and parts of the leaf were examined and demonstrated in anatomical studies

Remarks using the sem method species seeds of Gentiana occurring in turkey [Observações utilizando o método SEM de sementes de espécies de gentiana ocorrentes na Turquia]

Seeds of eleven perennial Gentiana collected from Turkey were analyzed using the SEM method. Other species excluding G. septemfida, G. boissieri, G. gelida were studied for the first time. They were identified and compared in terms of seed characteristics and surface ornamentations. Major characteristics including the outer periclinal walls of testa, sculpting of inner periclinal walls, seed shape, seed and testa cell, wing cell size, thickness of testa wall and seed shape have been proposed for Turkey Gentiana. They are divided into different types, such as no wing, chalazal wing, incomplete discoid wing, complete discoid wing according to the outer periclinal walls of testa. Considering primary sculpting of seeds, irregularly striate and shallowly reticulate type is observed. Anticlinal walls of G. olivieri, G. boissieri and G. gelida are curved, while others are straight. G. lutea has the largest mean seed (4.20 x 4.40 mm), while G. cruciata (0.67 x 0.60 mm) and G. olivieri have the smallest mean seeds (0.67 x 0.67 mm). Seed micromorphology can be used together with morphological character to form classifications in studied specimens for Gentiana genus. © 2017, Sociedade Brasileira da Ciencia das Plantas Daninha.
