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.

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.

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.

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.

The aquatic plant Pistia stratiotes L. is environmentally hazardous and requires effective methods for its utilization. The harmfulness of these plants is determined by their excessive growth in water bodies and degradation of local aquatic ecosystems. Mechanical removal of these plants is widespread but requires fairly resource-intensive technology. However, these aquatic plants are polymer-containing substrates and have a great potential for conversion into bioenergy. The aim of the work was to determine the main patterns of Pistia stratiotes L. degradation via granular microbial preparation (GMP) to obtain biomethane gas while simultaneously detoxifying toxic copper compounds. The composition of the gas phase was determined via gas chromatography. The pH and redox potential parameters were determined potentiometrically, and Cu(II) concentration photocolorimetrically. Applying the preparation, high efficiency of biomethane fermentation of aquatic plants and Cu(II) detoxification were achieved. Biomethane yield reached 68.0 ± 11.1 L/kg VS of Pistia stratiotes L. biomass. The plants’ weight was decreased by 9 times. The Cu(II) was completely removed after 3 and 10 days of fermentation from initial concentrations of 100 ppm and 200 ppm, respectively. The result confirms the possibility of using the GMP to obtain biomethane from environmentally hazardous substrates and detoxify copper-contaminated fluids.

Viable Seeds

In temporary ponds, seed germination largely determines how well aquatic plant assemblages recover after dry periods. Some aquatic plants have terrestrial morphotypes that can produce seeds even in dry years. Here, we performed an experiment to compare germination patterns for seeds produced by aquatic and terrestrial morphotypes of Ranunculus peltatus subsp. saniculifolius over the course of five inundation events. During the first inundation event, percent germination was higher for terrestrial morphotype seeds (36.1%) than for aquatic morphotype seeds (6.1%). Seed germination peaked for both groups during the second inundation event (terrestrial morphotype: 47%; aquatic morphotype: 34%). Even after all five events, some viable seeds had not yet germinated (terrestrial morphotype: 0.6%; aquatic morphotype: 5%). We also compared germination patterns for the two morphotypes in Callitriche brutia: the percent germination was higher for terrestrial morphotype seeds (79.5%) than for aquatic morphotype seeds (41.9%). Both aquatic plant species use two complementary strategies to ensure population persistence despite the unpredictable conditions of temporary ponds. First, plants can produce seeds with different dormancy periods that germinate during different inundation periods. Second, plants can produce terrestrial morphotypes, which generate more seeds during dry periods, allowing for re-establishment when conditions are once again favorable.
