Descriptive Anatomy And Evolutionary Patterns Of Anatomical Diversification In Adenia (Passifloraceae), David J. Hearn
Descriptive Anatomy And Evolutionary Patterns Of Anatomical Diversification In Adenia (Passifloraceae), David J. Hearn
Aliso: A Journal of Systematic and Floristic Botany
To understand evolutionary patterns and processes that account for anatomical diversity in relation to ecology and life form diversity, anatomy of storage roots and stems of the genus Adenia (Passifloraceae) were analyzed using an explicit phylogenetic context. Over 65,000 measurements are reported for 47 quantitative and qualitative traits from 58 species in the genus. Vestiges of lianous ancestry were apparent throughout the group, as treelets and lianous taxa alike share relatively short, often wide, vessel elements with simple, transverse perforation plates, and alternate lateral wall pitting; fibriform vessel elements, tracheids associated with vessels, and libriform fibers as additional tracheary elements; …

Propagation Of Endangered Thermopsis Turcica Tan, Vural & Küçüködük Using Conventional And In Vitro Techniques, Süleyman Cenkçi̇, Mehmet Temel, Mustafa Kargioğlu, Sergun Dayan
Turkish Journal of Biology
This report deals with the successful clonal propagation of endangered T. turcica using rhizome cuttings and epicotyl explants. Rhizome cuttings were treated with \alpha-naphthaleneacetic acid (NAA) or indole-3-butyric acid (IBA) before planting for vegetative multiplication. Rhizome cuttings pretreated with NAA (10 mg/L) were both rooted and sprouted (66.6 percent) after 100 days. Application of NAA induced callus and adventitious root formation in epicotyl explants and 6-benzyladenine (BA) induced production of microshoots. Low levels of NAA (0.5-1 \muM) together with BA promoted shoot initiation and development. The highest regeneration rate (86.6 percent), with a mean number of shoots (3.05) and a …
Notes On The Sikkim Himalayan Rhododendrons: A Taxa Of Great Conservation Importance, Kaushal K. Singh
Notes On The Sikkim Himalayan Rhododendrons: A Taxa Of Great Conservation Importance, Kaushal K. Singh
Turkish Journal of Botany
Rhododendrons form dominating species all along the temperate, subalpine and alpine zones in the Sikkim Himalaya. Rhododendron L. is one of the largest genus of the Ericaceae family, occurring in the higher altitudes having ecological significance and economic importance in addition to its splendiferous flowers. It has aesthetic, sacred, aromatic, medicinal and fuelwood values. There are 36 species with 45 different forms (including subspecies and varieties) in the Sikkim Himalaya. Using IUCN guidelines for categorization eight species are being evaluated according to population characters. It has been observed recently that the rhododendrons of the region are under pressure, which are …
