AbstractBasic respiration characteristics were measured in turions of six aquatic plant species differing greatly in their ecological and overwintering characteristics both before and after overwintering, i.e., in dormant and non-dormant state: non-carnivorous Hydrocharis morsus-ranae and Caldesia parnassifolia and carnivorous Aldrovanda vesiculosa, Utricularia australis, U. ochroleuca, and U. bremii, and in non-dormant winter apices of three Australian (sub)tropical populations of Aldrovanda and of two temperate North American Utricularia species, U. purpurea and U. radiata. Respiration rate of autumnal (dormant) turions at 20°C ranged from 0.36 to 1.3 µmol O2 kg−1 (FM) s−1 and, except for U. bremii, increased by 11–114% after overwintering. However, this increase was statistically significant only in two species. Respiration Q10 in dormant turions ranged within 1.8–2.6 and within 2.3–3.4 in spring (non-dormant) turions. Turions of aquatic plants behave as typical storage, overwintering organs with low respiration rates. No relationship was found between respiration rate of turions and overwintering strategy. In spite of their low respiration rates, turions can usually survive only from one season to another, due to their limited reserves of respiratory substrates for long periods. Contrary to true turions, respiration rates in non-dormant winter apices both in Australian Aldrovanda populations and temperate U. radiata and U. purpurea, in sprouting turions, and growing shoot apices of Aldrovanda were high and ranged from 2.1 to 3.1 µmol kg−1 (FM) s−1, which is comparable to that in aquatic plant leaves or shoots.

Different Parts

Nelumbo nucifera Gaertn (Nymphaeaceae), a perennial aquatic plant, has been used as a medicinal herb in China and India. It has been recorded in the most famous medicinal book in China for more than 400 years. Different part of plant (leaves, seeds, flower, and rhizome) can be used in traditional system of medicine. In traditional system of medicine, the different parts of plant is reported to possess beneficial effects as in for the treatment of pharyngopathy, pectoralgia, spermatorrhoea, leucoderma, smallpox, dysentery, cough, haematemesis, epistaxis, haemoptysis, haematuria, metrorrhagia, hyperlipidaemia, fever, cholera, hepatopathy and hyperdipsia. Following the traditional claims for the use of N.nucifera as cure of numerous diseases considerable efforts have been made by researchers to verify it’s utility through scientific pharmacological screenings. The pharmacological studies have shown that N.nucifera posseses various notable pharmacological activities like amti-ischemic, antioxidant, anticancer, antiviral, antiobesity, lipolytic, hypocholestemic, antipyretic, hepatoprotective, hypoglycaemic, antidiarrhoeal, antifungal, antibacterial, antiinflammatory and diuretic activities. A wide variety of phytoprinciples have been isolated from the plant. The present review is an effort to consolidate traditional, ethnobotanic, phytochemical and pharmacological information available on N.nucifera.

Schumacher and Halbsguth first demonstrated ectodesmata as pores or channels in the epidermal cell walls in haustoria of Cuscuta odorata L. by light microscopy in tissues fixed in a sublimate fixative (30% ethyl alcohol, 30 ml:glacial acetic acid, 10 ml: 65% nitric acid, 1 ml: 40% formaldehyde, 5 ml: oxalic acid, 2 g: mecuric chloride to saturation 2-3 g). Other workers have published electron micrographs of structures transversing the outer epidermal cell in thin sections of plant leaves that have been interpreted as ectodesmata. Such structures are evident following treatment with Hg++ or Ag+ salts and are only rarely observed by electron microscopy. If ectodesmata exist without such treatment, and are not artefacts, they would afford natural pathways of entry for applied foliar solutions and plant viruses.

Commercial Market

Bucephalandra sp. is a genus of aquatic plants endemic to Borneo Island, representing the Araceae family. Bucephalandra sp. is famous for its ornamental aquatic plants which are usually used in aquascaping. These aquatic plants come at fantastic prices, e.g. ±300 euros in European ornamental aquatic markets and Rp 50,000 – 700,000 in Indonesian aquatic plant markets. We collected 195 types of Bucephalandra from an ornamental aquatic plant market in Jakarta. In the market, they are sold under its commercial name. Therefore, the aim of this study is to collect and identify the species of all Bucephalandra types in the aquatic plant commercial market. These species that we identified are based on botanical taxonomist identification in the Herbarium Bogoriense Department Botany – Research Centre for Biology – Indonesian Institute of Science (LIPI) Cibinong. The result of this study is from our collection (195 types) of which 102 types are Bucephalandra Motleyana Schott species and 90 types are the other species of Bucephalandra.

Effective Drugs

Fevers are considered as the most important parameters to evaluate and diagnose most of the disease conditions like inflammations, wounds and other infections. There are effective drugs that treat and control the fevers out of which NSAID's are most important ones. They cause notable side effects like gastric ulcers, gastric mucosal perforations etc. which make the use of those drugs limited. Herbs are used to treat various diseases, starting from the evolution of the human race. During this, herbs had been introduced to many types of tests and scientific investigations to prove the activities that herbs possess. The diseases that the herbs are used for are notable in the medical systems like Ayurveda and other systems. The need for the validation of the activities of the herbs and medicinal plants is utmost important these days. The extracts of the plant leaves of Desmodium gangeticum were extracted with ethanol and then investigated for the antipyretic activity in yeast induced pyretic method. The extract was tested in two doses 200 and 400mg/kg. This was found significant when compared to the standard drug.
