That being said, I think a lot has changed for the better in the last 20 years that I have been in science and the climate is still improving. A second challenge that women ...
متن کاملMorphology and Structure of Biomorphous Silica Isolated from Equisetum hyemale and Equisetum telmateia
The family of horsetails (Equisetaceae) is characterized through their high content of silica (SiO2), which is the highest in known vascular plants. This work has focussed on two species of this family, Equisetum hyemale and Equisetum telmateia, where the biomorphous silica is deposited basically as amorphous SiO2 in the outer epidermis of the plants. As source of SiO2, the original plant mater...
متن کاملPb detoxification in Equisetum diffusum
Current research highlights the use of aquatic macrophyte Equisetum diffusum (Himalayan horsetail) for lead detoxification. This plant species can grow in waste cathode ray tube (CRT) powder and absorbs its Pb. X-ray fluorescence spectroscopy (XRF) analysis of plant ash shows that 68 mg/kg lead concentration in the untreated plant was improved to 7600 mg/kg in CRT powder after 90 days. The role...
متن کاملIn Vitro Propagation of Croton (codiaeum Variegatum)
Croton (Codiaeum variegatum) with its amazing colors and leathery leaves is regarded as a beautiful foliage plant. The plant is native of South East Asia. Generally crotons are multiplied vegetatively by means of cuttings and air layering. This process is slow in response and need to maintain large number of mother plants stock. Micropropagation is an alternative mean of propagation that can me...
متن کاملThe first Cenozoic Equisetum from New Zealand
Equisetum is described for the first time from Cenozoic deposits of New Zealand. The fossils derive from two early to earliest middle Miocene assemblages in South Island, New Zealand. The fossils are ascribed tentatively to subgenus Equisetum based on their possession of whorled branch scars, but they cannot be assigned with confidence to a formal species. The decline of equisetaleans, otherwis...
