Morphological and anatomical evaluation on three varieties of Vitis vinifera (Trerash, Rash meri and Baidhaw) commonly known as grape vine was reported. The samples were prepared in a mixture containing 95% of alcohol and glacial acetic acid. The result revealed differences among the varieties ranging from morphological to aesthetic features of the leaf. Although, starch grains, druses and raphid crystals were present in all the varieties, the shape of the stem, petiole, midrib, lamina and margin were anatomically different as well as the presence of trichomes among the varieties. The microstructure of the leaf epidermis was investigated using light microscope (LM) and scanning electron microscope (SEM) which confirmed the polygonal shape of the leaf epidermal cells and the anticlinal walls which were straight and arched from the surface view. The structure of the stomata apparatus was present only in the abaxial epidermis and anomocyte type. SEM was used to investigate the pollen grains tricolporat and sub prolate often known as prolate-spheroidal. The flower was bisexual having size ranging between 4 to 5 mm.
Problem statement: Leea species was originally placed in the family Vitaceae but was later placed in the Leeaceae due to the anatomical differences between the two families. Approach: A comparative study on the stem and leaf anatomy of Cayratia mollissima and Pterisanthes caudigera (Vitaceae) and Leea indica (Leeaceae) was conducted to investigate anatomical differences which could provide additional differentiating characters for supporting this treatment. Results: The Transeverse Sections (TS) revealed species differences with respect to the shape of the stems, the leaf margin, midrib and petiole. Druses were present in the leaves and stems of both species, while raphides were present in the lamina. Conclusion: Starch grains and trichomes were present only in Cayratia mollissima and Pterisanthes caudigera.
Leea species was originally placed in the family Vitaceae but was later placed in the Leeaceae due to the anatomical differences between the two families and between species. A study on the anatomical difference in leaves of four species in the Vitaceae (Tetrastigma cruciatum, Pterisanthes miquelii, Cissus hastata and Nothocissus spicifera) and two species from Leeaceae (Leea rubra and Leea indica) was undertaken. Show that species from the two families differ in the shape of the transverse sections of the petiole and midrib. Druses and raphides are present in the petioles and midribs of Tetrastigma cruciatum, Pterisanthes miquelii, Cissus hastata and Nothocissus spicifera, while in Leea rubra and Leea indica only druses are present. Starch grains are present in the pith of the Vitaceae species studied but are absent in both L. rubra and L. indica
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
