Keywords: Flora, Kole wetlands, Thrissur, Kerala
Abstract: The study was conducted from November 1998 through October 2003. The Kole wetland is one of the largest and highly producive wetlands and it is also one of the most threatened wetland in the State. Etymology of "Kole" refers to the peculiar type of paddy cultivation carried out from December to May and this Malayalam word indicates bumper yield of high returns if in case floods do not damage the crops. Agriculture is the major occupation of the people of Kole wetlands and ninety percent people were practicing agriculture mostly paddy. Total of 140 species belonging to 23 F families of Dicotylendons and 11 families of Monocotyledons and 5 water fern families were recorded from the Kole wetlands. Prominently represented family is Cyperaceae (27 genera) followed by Poaceae (25). The other dominant families are Asteraceae, Fabaceae and Hydrocharitaceae. Reclamation of land and changes in land use pattern are the most serious problems. The Kole lands are being converted to coconut, areca nut, banana plantations and other cash crops at an alarming rate. Various species of grasses and sedges comprises the floristic spectrum of Kole wetlands and have great value of ecological and economic importance.

Keywords: Taxus baccata, Himalayan yew, Auxins, IBA, Rooting, Conservation, Macro-propagation
Abstract: Himalayan Yew (Taxus baccata Linn.), an important medicinal plant, is critically endangered due to over-exploitation for the isolation of Taxol, an exciting anti-cancer drug from its bark and leaves. Since the species is unisexual and its natural regeneration via seeds is poor and as the seed raised plants add little growth, propagation by stem cuttings was tried and considerable success was achieved after making use of different auxins (IAA, IBA and NAA) in different concentrations. Of the 10 treatments studied, IBA at 500 ppm performed best, registering higher callusing percentage, rooting percentage, number of roots and length of roots in the juvenile shoot cuttings of the species. The results achieved through the application of auxins may possibly be the only practical and viable option for augmenting natural regeneration and also for the large scale propagation and thereby conservation of this threatened versatile Himalayan asset. The technique evolved will be most handy and can be applied any where in its natural habitat for overcoming the chances of its extinction.

Keywords: Lesser known trees, Andaman & Nicobar Islands
Abstract: Andaman and Nicobar Islands are classified as one of the 12 biogeographical zones of India. The vegetation of these islands is classified as ' Littoral ' and ' Inland ' . These islands represent 700 genera belonging to 140 families. About 14% of angiospermic species are endemic to these islands. The flora of Andaman Group of islands is distinct from that of Nicobar. This paper records 52 Lesser Known Timber Trees of these Islands. Tropical forests, the centres of biodiversity and the cradle of evolution, have been the worst affected. They were being destroyed at the rate of 100,000 km2 every year. Most of the species in Andaman & Nicobar Islands are poorly known not only taxonomically but also from economic point of view. The vegetation of these islands are the only last bit of tropical evergreen Malesian available within territory with great use for future generation. It is also clinging on a very delicate balance in the face of grave threat from encroaching civilized man. In order to protect and preserve them for posterity, it is strongly recommended for immediate implementation that steps to be taken to establish a Arboretum of tropical region near Port Blair where rare, endemic and endangered species can be conserved and propagated, for that Rutland Island is quite ideal.

Keywords: Neem, Azadirachta indica, seeds, Drying methods, Viability, storability, Seedling performance
Abstract: Neem seeds are short lived and require quicker and more uniform drying to maintain viability and vigour. After proper cleaning, seeds were dried in the sun, shade, dryer at 45 + 1oC and 55 + 1oC. Seeds dried in shade, reached at 7.2% EMC (equilibrium moisture content) after 168 hours. While seeds dried in dryeer at 55 + 1oC reached at 5% EMC within 40 hours followed by Sun drying (56 hours) and dryer at 45 + 1oC (144 hours). After reaching EMC, seeds were tested for their viability and vigour under controlled conditions and in nursery too. Seeds were sown in nursery upto 60 days for evaluating the seedling performance in terms of total seedling length, number of leaves, collar diameter, total biomass and vigour index. All seed lots were stored in open containers at ambient room temperature (35 + 5 oC) and tested at various intervals of storage viz. Fresh/0, 60, 90, 105, 120, 158, 180 and 275 days. Shade dried seeds showed higher mean viability period (P50 ) of 172 days followed by seed dried through drier at 45 + 1oC (113 days) as compared to sun-dried seeds (40 days). Seeds dried in shade found best followed by dryer at 45 + 1oC in terms of seed and seedling performance and storability.

Keywords: Taxus baccata Linn. (Yew, Thuner), bone fractures, propagation
Abstract: Taxus baccata Linn. (Yew, Thuner) is an endangered (Ewald et al., 2002) longlived, slow growing evergreen tree species, widely distributed throughout Europe (Garcia et al ., 2000) and Asia. In Uttarakhand, it is distributed between 1,800 and 3,300 m amsl (Anon., 1976), and is locally known as ' Thuner ' . In the traditional folk medicinal system, paste prepared from its leaves is used as a plaster on bone fractures and applied externally on the forehead to provide relief from headache (Gaur, 1999); leaves are credited with emmenagogue and antispasmodic properties. They are employed for the treatment of hysteria, epilepsy and nervousness and as a lithic in calcium complaints (Chauhan, 1999). Bark is used for preparing beverages locally known as ' Namkin Chay ' . The tree has received much attention during the recent past because of its leaves; bark and stem are the prime source of Taxol (Purohit et al ., 2001) and 10-deacetylbaccatin III, a potent anti-cancer drug. The blatant exploitation of the species in recent years has created serious concern about its long term health in the already diminishing natural populations and in many parts facing danger of extinction. Natural regeneration of T. baccata takes place through seeds and seedlings survive only under shady conditions. Seeds remain dormant and generally took 1-2 years in germination. The common method for its artificial regeneration is through branch cuttings. But after the knowledge about its tremendous medicinal use, a large number of branch cuttings are being taken regularly from its trees in nature and so there is a serious concern about its natural population. Hence, an experiment was carried out to develop a suitable technique for its propagation through seed.
