Aiming to identify the populations of aquatic plants present in the Porto Primavera reservoir and evaluate the behavior of Hydrilla verticillata colonization of this water body a survey was carried out in 2007. The data was based on presence or absence, only were assessed the presence or absence of the species and the data were subjected to cluster analysis to establish differences in distribution and occurrence of populations. The community of aquatic plants showed 24 species distributed in 16 botanical families. Cyperaceae and Pontederiaceae were the most representative in terms of species richness. The submerged macrophyte Hydrilla verticillata showed the highest frequency of occurrence in the water body, showing a different behavior from the other populations of the water body. Species like Eichhornia crassipes, Eichhornia azurea, Typha dominguensis and Oxycaryum cubense also showed different behavior in relation to other populations within the community, forming large populations in lagoons and backwater areas.

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.

Submerged Aquatic Plant

The potential of three submerged aquatic plant species (Cabomba piauhyensis, Egeria densa, andHydrilla verticillata) to be used for As, Al, and Zn phytoremediation was tested. The plants were exposed for 14 days under hydroponic conditions to mine waste water effluents in order to assess the suitability of the aquatic plants to remediate elevated multi-metals concentrations in mine waste water. The results show that theE. densaandH. verticillataare able to accumulate high amount of arsenic (95.2%) and zinc (93.7%) and resulted in a decrease of arsenic and zinc in the ambient water. On the other hand,C. piauhyensisshows remarkable aluminium accumulation in plant biomass (83.8%) compared to the other tested plants. The ability of these plants to accumulate the studied metals and survive throughout the experiment demonstrates the potential of these plants to remediate metal enriched water especially for mine drainage effluent. Among the three tested aquatic plants,H. verticillatawas found to be the most applicable (84.5%) and suitable plant species to phytoremediate elevated metals and metalloid in mine related waste water.

We tested several plants for the occurrence of unusual polyamines such as homospermidine, aminopropylhomospermidine, norspermidine, norspermine, thermospermine, and caldopentamine. The leaf and root of aquatic plants ubiquitously contained homospermidine in addition to usual polyamines such as putrescine, spermidine, spermine, and cadaverine. Homospermidine was widely distributed in the seed, seedling, leaf, and root of gramineous plants such as rice, millet, oat, rye, wheat, barley, corn, sorghum, and timothy as a minor polyamine. Aminopropylhomospermidine was found in the two aquatic plants, the water lily Nymphaca tetragona and the lotus Nelumbo nucifera as a major polyamine, and in the gramineous seeds as a minor polyamine. Norspermidine, norspermine, homospermine, and caldopentamine were detected in two floating aquatic plants, the duckweed Spirodela polyrhiza and the water hyacinth Eichhornia crassipes. Thermospermine was sporadically detected in some aquatic plants and gramineous seeds. Key words: Gramineae, aquatic plant, polyamine, homospermidine, caldopentamine.

Gondia is one of the centrally located districts of India. It is famous for its lakes and water bodies. These water bodies exhibit enormous diversity of plants according to geographical location, depth of water body, water regime, chemistry of water, soil and sediment characteristics. Very little work has been done so far on the flora of the water bodies of Gondia district. Therefore, a study has carried out to understand the aquatic plants diversity of selected 5 lakes around Gondia city. For this, well-planned surveys were carried out at selected sites frequently. During visits, data like habit, life span, local names, and life forms of all the plant species present in the water body were collected. During the study, 44 species of 37 genera belonging to 26 families have been recorded from selected sites. Most dominant family was Hydrocharitaceae with 4 genera and 4 species, followed by Asteraceae, Poaceae, Convolvulaceae and Potamogetonaceae with 3 species each. Jaccard and Sorenson similarity indexes showed that Lake I and Lake II have maximum similarity and highest diversity as compared to other sites. The present work revealed the database of aquatic plants in water bodies around Gondia, which will help in future work for the conservation, preservation and growth of the local biodiversity.

Native aquatic plants are important to maintaining a balanced ecosystem, but they often are displaced by exotic invasive plant species. The research on the control and growth of the invasive aquatic species hydrilla (Hydrilla verticillata) using sand substrates and controlled-release fertilizers (CRF) provides a potential production technique for other aquatic plants. We questioned if we could use hydrilla production techniques to grow southern naiad (Najas guadalupensis), a Florida-native aquatic plant that is often mistaken for hydrilla. We grew southern naiad cuttings in containers filled with 100:0, 75:25, 50:50, 25:75, or 0:100 coarse builder’s sand and sphagnum moss (by volume). Before planting, containers were fertilized with 0, 1, 2, or 4 g·kg−1 CRF (15N–4P–10K). Containers were submerged in large storage tubs filled with rainwater and grown for 8 weeks. Southern naiad shoot dry weight was greater in the 100% sand substrate than that in the 0% sand substrate. Substrate electrical conductivity (EC) levels were greater in the 0% sand with no difference among the other substrates. Shoot and root dry weight of plants fertilized with 1–2 g·kg−1 CRF were greater than 0 or 4 g·kg−1 CRF. Substrate EC also increased as fertilizer rate increased, with the highest EC observed at 4 g·kg−1 CRF. Based on our results, we would suggest growing southern naiad in substrates with 100% sand and fertilized with 1–2 g·kg−1 CRF.

Desiccation Rate

AbstractDesiccation following prolonged air exposure challenges survival of aquatic plants during droughts, water drawdowns, and overland dispersal. To improve predictions of plant response to air exposure, we observed the viability of vegetative fragments of 10 aquatic plant species (Cabomba caroliniana, Ceratophyllum demersum, Elodea canadensis, Egeria densa, Myriophyllum aquaticum, Myriophyllum heterophyllum, Myriophyllum spicatum, Potamogeton crispus, Potamogeton richardsonii, and Hydrilla verticillata) following desiccation. We recorded mass loss, desiccation rate, and plant fragment survival across a range of air exposures. Mass loss accurately predicted viability of aquatic plant fragments upon reintroduction to water. However, similar periods of air exposure differentially affected viability between species. Understanding viability following desiccation can contribute to predicting dispersal, improving eradication protocols, and disposing of aquatic plants following removal from invaded lakes or contaminated equipment.

Tweed Structure

Natural Amelia albite (Ab99.3An0.1Or0.6) annealed at 1073° and 924°C for various periods up to 140 days has been studied by NMR. TEM studies of the same sample revealed a distinct tweed microstructure in some samples annealed at both 1073°C and 924°C. On the whole, the quasi-regular tweed has a periodicity of 100 - 200 Å in both directions, one nearly normal to b* and the other approximately parallel to b*, which gives rise to two-directional streaking in SADP’s (Fig. 1 and 2). However, there are some differences in the tweed structure developed on annealing at 1073°C and at 924°C in albite.Albite samples annealed at 1073° show a systematic trend in their development of tweed structures: the regularity, periodicity, and frequency of occurrence increase with annealing time during the first 3 days, and then decrease gradually until no tweed microstructures are seen in samples annealed for more than 15 days. The tweed structure proceeds locally to form one-directional twin-like microstructures.

Purification Efficiency

The effluent from activated sludge treatment of petroleum wastewater was treated with the aid of a ponding system using aquatic plants (Water Hyacinth, Chlorella, Reed). A good result was obtained in this study. Pilot pond system shows that the purification efficiency depends on the residence time of about 14 days. The petroleum removal waa 97-98 %, the COD removal was from 88-93 %. The dissolved oxygen amount (with Chlorella) increased from 0.7 mg/l to 9.8 mg/l and the pH increased from 6.9 to 8-8.6. The application of 3 step biological pond with the use of Water Hyacinth, Chlorella, Reeds for post treatment of petroleum wastewater is appropriate in Vietnam.
