The germination was most effectively induced by red light and somewhat by green and far-red, but not at all by blue light.
vittata , common by the view-point on the main highway road on the way up to Pune. spores and gametophytes promises efficient reproduction. Ladder brake (Pteris vittata) is one of the smaller brake ferns, reaching heights of only 1 to 3 feet.
Abstract. Percent PpR-Dependent Germination of Spores in Pteris vittata1 Masaki Furuya2, Akeo Kadota3 and Hisako Uematsu-Kaneda Botany Department, Faculty of Science, University of Tokyo, Hongo, Tokyo 113, Japan The phytochrome-dependent germination of spores was studied in the fern Pteris vittata. Frond and root samples of 150 ferns at peak spore maturation … Plants usually grow in well drained places or in the crevices of rocks. Typical Pteris vittata subsp. Furthermore, the bioconcentration factor, defined as the ratio of shoot As concentration to soil As concentration, was greater than 10. Ferns are an ancient plant group that produces spores… Looks like young plant of Pteris to me. Abstract. Pteris vittata is adapted to a variety of soils, whilst its ability to accumulate arsenic has meant it has attracted the attention of people interested in using plants to extract heavy metals from soils; phytoremediation or phytoextraction. (a) Main view (b) Top view Pteris vittata has been reported to be a hyperaccumulator of arsenic, and therefore useful in phytoremediation to clean-up arsenic-contaminated soils. Although factors for successful germination of spores have been identified, but information Pteris vittata spore is relatively small, and the existing hole disk seeder is not suitable for Pteris vittata sowing requirements. ADVERTISEMENTS: Occurrence and Distribution: This is a cosmopolitan fern being distributed in almost all geographical regions. The website also provides access to a database and images of plants photos and herbarium specimens found at … Epiphytic orchid in Manipur No. Spores were collected from these ferns and cultured in artificial nutrient medium to grow the gametophytes.
Ito (1970) observed that when 5-day-old, one-celled prothalli of Pteris were exposed to red light, the mitotic activity was low; after 8 days, 80% of the plants had divided only once. The object of this study was to characterize the pattern of cell morphogenesis and synthesis of nucleic acids and proteins during phytochrome-controlled germination of spores of the fern, Pteris vittata.Phytochrome activation and germination were initiated in fully imbibed spores by exposure to a saturating dose of red light. Gametophytes show various types of abnormalities Abstract: Three populations of a common road side fern Pteris vittata L. were collected from three different localities situated in Patna with varying level of pollution. may be Pteris vittata. Concentrations of chemical analogs arsenic (As) and phosphorus (P) were measured in As-hyperaccumulator (Pteris vittata; PV) and three non As-hyperaccumulators (Thelypteris kunthii, Nephrolepsis brownii, and N. falcata) to draw inferences regarding their uptake from soils to roots and translocation to fronds and spores. They are very common along the slopes of hills and can be seen even at 1200 metres above sea […]
Pteris vittata was the first identified hyperaccumulator for Arsenic.T his fern can accumulate up to 22 630 mg As kg −1 in the shoot (frond) dry weight (d. wt). On the basis of the existing seeder, a mixing mechanism is designed to mix spores and water evenly and then spray sowing, so as to improve the sowing efficiency of Pteris vittata.

The authors thank Dr. Lena Ma, University of Florida, Gainesville, for providing the spores of Arsenic hyperaccumulator Pteris vittata. Spores of the fern Pteris vittata did not germinate under total dark conditions, while an exposure of the spores to continuous white light brought about germination.
