Araceae - Science topic

I am conducting an experiment on the effectiveness of water lettuce (Pistia stratiotes) in reducing TDS in wastewater. Over the first 7 days, TDS increased significantly (from 1200 ppm to 1500 ppm), while other parameters like COD, nitrate, phosphate, TSS, and turbidity decreased. Between days 8 to 10, TDS began to slowly decrease (by 30-40 ppm per day). Based on biochemical processes or plant absorption mechanisms, what could explain these results in my phytoremediation experiment?

Can phytoremediation be a solution to reduce TDS in wastewater? Especially by using aquatic plants such as Water Lettuce (Pistia stratiotes) or Water Hyacinth (Eichhornia crassipes)?

I would like to ask for advice, particularly from researchers specializing in phytoremediation processes. What are the main aspects that determine the success of phytoremediation in reducing levels of inorganic ions (such as Na, Mg, Ca, etc.) and heavy metal ions, especially on a large scale?

I am truly feeling desperate because my research (phytoremediation using Pistia stratiotes to reduce TDS in small-scale wastewater, specifically 20 liters) has yet to show the expected results and has failed to support my initial hypothesis.

Hello, I am a final-year undergraduate student conducting my thesis research project at a company in the polymer dispersion industry. This company generates wastewater with a high TDS concentration. I am conducting research to reduce the TDS level using phytoremediation with water lettuce on a small scale. However, the TDS keeps increasing, and the condition of the plants is deteriorating. My questions are:

I currently have one Amorphophallus (a type of aroid) in my resident area and it start to has wilting sign (fairly common for Amorphophallus when it want to change leaf, enter dormant stage, or preparing to flower). I want to keep some part of the standing leaf of Amorphophallus for future use, mainly on DNA extraction.

Good day,

i have a general question about tissue culture.

I have found the following recipe for Epipremnum Aureum "Marble Queen":

Leaf Explant: MS Medium + 4.54 µM TDZ + 1.07 µM NAA (Thidiazuron in Micropropagation of Aroid Plants by Chen and Wei (2018), p. 105, DOI: 10.1007/978-981-10-8004-3_4)

Specifically, I have the following questions.

1) Do i only need to autoclave the agar with distilled water (I use a pressure cooker for this) and when the agar has cooled down a bit just add the MS, TDZ and NAA and mix it or do i need to autoclave the MS as well?

2) Will the TDZ dissolve in the agar water at all and how hot can the agar water be to add the MS, TDZ and NAA?

3) Is it even necessary to autoclave the water incl. agar (in the pressure cooker) if I clean all the jars with NaClO (sodium hypochlorite)?

Thank you in advance!

I am doing aroid research and several explants already proliferated into shoots and others. Then after several weeks, my explants, the leaves, changed their color into yellowish-green. What makes it change? Is it because of the nutrition compound in the media or the age of the explant or anything? Thank you so much.

Xanthosoma violaceum is a member of Araceae (Dastar Kachu in Bengali). It has fleshy leaves. How should I prepare a herbarium sheet for it, like how should I dry the sample, what is the standard technique for pressing this plant or similar kind of fleshy plant for e.g. Aloe vera, Bryphyllum pinnatum etc. Thanks in advance.

As you know, Monstera is very popular house plant and some has unusual mutation with reduced number of chlorophyll and in some cases, chlorophyll pigments completely lost in leaves. Is it possible to make chlorophyll degradation in leaves under lab conditions?

This plants may be Araceae family member.

It is an excellent work. In our study, we noticed the ability of oxalic acid to form co-crystals with cholesterol and also with sodium ions. Oxalic acid is found in many medicinal plants. But the question is that What is ithe role of oxalic acid to co- precipitate many phytochemicals , especially terpinoids/ steroids/ alkaloids. phenolics or even flavonoid compounds that may have emmense pharmaceutical relevance.Generally we Botanists consider it as an excretary product. But I firmly believe that the oxalic acid in oxalidacea, Aracea etc has a crucial role to release pharmaceutically relavant phytochemicals slowly to the biosystem. In otherwards it also has a chelating property to bind certain metal ions (Na + etc) and in excess concentration may lead to form calcium oxalate.

I need information about the characteristics of taxonomic importance at the section or subgenus level in Anthurium

I am undertaking an in vitro study on the screening of four aroid specie using PEG6000 as the drought inducing agent and need advice on how the osmotic potential of the media is taken - device used and procedures if necessary.
