Pteridophytes as active components in gardening, agricultural and horticultural ecosystems in Japan
Advances in horticultural science, 2015
Many members of Pteridophytes have been traditionally used in the designs of Japanese gardens and a large variety of ferns attract gardeners as greening pieces in the garden designs. However, details or examples of practical uses of ferns in traditional gardening in Japan have only rarely been introduced in non-Japanese literatures to date, despite the importance of ferns in Japanese gardening traditions. In addition to the discussion of ferns in gardening, the use and association of these plants in Japanese agricultural and horticultural sceneries are addressed. The presence and importance of 40 familiar fern species in local gardening, agricultural and horticultural ecosystems are also discussed, as well as the roles of introduced ferns as key elements of ecosystems and their interaction with neighboring biota. Finally, some examples of uses of fern species in environmental science and engineering are also reviewed.
Diversity of Fern Flora for Ecological Perspective – A Review
Int. J. Pure App. Biosci. 6 (5): 339-345 , 2018
One of the important cut foliage and indoor potted plant grown for its attractive foliages is fern. The foliage of fern is highly valued in the international florist greenery market because of its long post-harvest life, low cost, year round availability and versatile design qualities in form, texture and colour. Ferns (Pteridophytes) are the seedless vascular plants, dominated the vegetation on earth about 280-230 million years ago. Although they are now largely replaced by the seed bearing vascular plants in the existing flora today, yet they constitute a fairly prominent part of the present day vegetation of the world. India with a highly variable climate has a rich diversity of its flora and Pteridophytic flora greatly contributes to its diversity. Pteridophytes also form an interesting and conscious part of our national flora with their distinctive ecological distributional pattern. There are about 12,000 species of pteridophytes occur in the world flora, of which 1,000 species belonging to 70 families and 192 genera occur in the different parts of the present Indian political boundary. Western Himalaya and Western Ghats supported 399 and 349 pteridophytes species of fern and fern allies in India, respectively. Hence, it is need of the hour for documenting the available fern diversity and selection of superior genotypes. Key words: Ferns, Pteridophytes, Diversity, Pollution.
Diversity of Ferns (Pteridophyta) in the Several Mountains of West Java
BIOLINK (Jurnal Biologi Lingkungan Industri Kesehatan)
The diversity of ferns (Pteridophyta) in the five mountainous in West Java (Mt. of Patuha, Papandayan, Tangkuban Perahu, Pangrango, and Guntur) has not been widely reported. The aim of this research was to obtain data on diversity and similarity of fern species in the five mountains in West Java. This research was conducted by exploring and descriptive analysis method. Comparison of species diversity among all reseach field were calculated by the index of species similarity according to Sorenson. The diversity of ferns in Mt. Patuha, Papandayan, Tangkuban Perahu, Pangrango, and Guntur were 27, 14, 26, 40 and 5 species, respectively. The total number of ferns species in five locations are 83 species from 25 families. Comparison of species diversity among fileds based on the Sorenson similarity index is low (<50%), except between the Mt. Patuha and Mt. Papandayan areas is high (> 50%).
The study was carried out to investigate the taxonomic occurrence of Pteridophytes in Lafia and Doma Metropolis of Nasarawa State, Nigeria. A total of 16 locations were sampled in Lafia and Doma respectively. These locations include wetlands, swamps, forest shade and trees. From these locations, ferns were collected, pressed and identified. Their relative abundances in each location were calculated and their ethnobotanical uses by the local dwellers were documented using structured questionnaires. Ferns were observed only in 12 locations in Lafia and nine locations in Doma. Seven species of ferns were identified namely, Pneumatopteris afra, Nephrolepis biserrata, N. undulata, N. cordifolia, Adiantum capillus-veneris, Adiantum sp. and Pityrogramma calomelanos. Pneumatopteris afra was found to be the most widely distributed fern. Of the ferns observed, terrestrial ferns had the highest occurrence (85.7%) in Lafia with only 50% in Doma. Pneumatopteris afra was found to have the highest relative frequency while Nephrolepis biserrata and N. undulata had the lowest relative frequency in Lafia and Doma. All these species have been reported by the local dwellers to have ethnobotanical uses such as in the treatment of ulcer, fever, typhoid, chest pain, stomach pain and diabetes. Also, Pityrogramma calomelanos had the highest percentage awareness by the local dwellers. It is concluded that Lafia is more rich and diverse in fern species than Doma. Locations where ferns were absent are due to the long-term alterations in the microclimatic conditions by various human activities in those places. Fern gazette 20(7): 245-254
ROLE OF BOTANIC GARDENS FOR THE CONSERVATION OF SOME FERN SPECIES
Botanic gardens maintain collections of live plants mainly for study, for scientific research conservation or education.These gardens are being opened or developed to act as centers for plant conservation, study and education, particularly of plants native to their own regions. The present study highlights the role of botanic gardens for ex-situ conservation of some fern species which are distributed in the Nilgiri Hills of Tamil Nadu, India. These include 22 species belonging to 18 genera and 13 families.
