  Reproductive Structures of Pteridophyte The Pteridophyte sporophyte, besides being a prominent component of soil and vegetation, is an important ornamental plant in gardens and lawns. Indoors, its gracefulness and shape fit it ideally as a plant for pot culture in hallways and living rooms, especially during the months of November to March. Transportation of whole plants from one place to another without damage is attempted by packing them in sand, decomposed silt, ashes, or sawdust. Despite their rich horticultural value, many Pteridophytes are vanishing from nature due to indiscriminate destruction of their natural habitats and capturing of species for ornamental purposes. The best means of conservation is an adequate botanical knowledge of these plants, together with their habitats. The approaches of the non-destructive collection of herbarium specimens are now being stressed. The collection is also supplemented with data regarding the locality and habitat, so as to make it de...

  Evaluation of Antioxidant and Antidiabetic activity of White Oyster Mushroom ( Pleurotus   florida ) cultivated in  North Bengal Abstract: Oyster mushroom is one of the popular mushrooms cultivated in North Bengal.  Pleurotus florida  is one of the cultivated mushroom having high demand for its bright white colour, texture and good taste. Seasonal productivity of  P. florida  was estimated and it was observed that the production rate is higher in late rainy season to winter season as the fruiting body required moderately low temperature. Antioxidant activity of  P. florida  also evaluated in respect of DPPH scavenging activity and Free reducing antioxidant power (FRAP) activity which showed significant results.  In vivo  antidiabetic activity was also evaluated in using Streptozotocin induced albino rats and it was observed that the mushroom powder helps in lowering the blood glucose level and actively regain the body weight....
