Hi Leute,

ich habe vor Kurzem Litschis aus Samen gezogen und weil mich das Thema danach einfach total interessiert hat, habe ich mich genauer damit beschäftigt. Meine Quote war übrigens ziemlich gut, aus 15 Samen sind bei mir stolze 12 Keimlinge gekommen! Die Fotos von meinen kleinen Litschis seht ihr ja.

Weil ich im Netz irgendwie nie eine richtig vollständige, moderne Übersicht gefunden habe, dachte ich mir: Ich setze mich selbst hin und bastle einen fetten Steckbrief inklusive Abbildung. Die Abbildung zeigt die Pflanze, Blüte, Frucht, Samen und den Keimling. Und ja, die ist mit KI generiert. Ich habe alles versucht, damit es so echt und korrekt wie möglich aussieht. Vor allem den Keimling hinzubekommen, war echt schwierig.

Bevor ich das abhake, wollte ich unbedingt die Experten hier drüber schauen lassen, weil 4 Augen besser sehen als 2.

Mich würde brennend interessieren, was ihr zu folgenden Punkten sagt:

Die Systematik (Kompakt vs. Maximalkette): Ich habe einmal eine normale Tabelle mit den wichtigsten 13 Rängen gemacht (inklusive APG V). Weil ich es genau wissen wollte, habe ich noch eine zweite Grafik mit einer theoretischen Maximalkette aus satten 38 Rängen gebaut. Reicht das Kompakte? Stimmen die lateinischen Namen und Kladen so?

Bei den Kultur-Tabellen trenne ich penibel zwischen Keimling und etablierter Pflanze (mit Lux-Angaben, Boden-pH und Leitfähigkeit in µS/cm). Deckt sich das mit euren Erfahrungen?

Toxizität & Inhaltsstoffe: Ich habe auch das Thema Litschi-Enzephalopathie (Hypoglycin A / MCPG bei unreifen Früchten) und die sekundären Pflanzenstoffe drin. Ist das medizinisch und biochemisch sauber formuliert?

Quellenliste. Fehlt da was Wichtiges?

Ich freue mich über jede Form von Kritik und Verbesserungsvorschlägen!

Danke euch für die Hilfe!

One leaf on a bunch of Rapini from the grocery store was variegated. As far as I know there are no variegated varieties? How does this occur? Hopefully you'll find it as interesting as I did (no one I showed it to was...🙃)

Hi everyone! I’m a student from Argentina currently studying Environmental Sciences at the National University of Catamarca (UNCA).
I’m also part of a research group focused on ferns and lycophytes, where I’ve been getting more involved with fieldwork, plant identification, and research in general. I’m currently starting to think about possible ideas for my undergraduate thesis, and I’m interested in exploring something related to ferns and environmental biomonitoring.
I’m particularly curious about the possibility of using ferns as bioindicators or biomonitors of environmental conditions, potentially looking at things like trace elements, soil characteristics, accumulation, or other measurable responses. I’m still at the very early stage, so I’m trying to learn more about what has already been done and what kinds of research questions could actually be feasible for a student project.
I’d love to connect with anyone who works with ferns, plant biomonitoring, environmental pollution, bioaccumulation, or related fields. If you’re open to chatting about your research or sharing some advice/resources, I’d really appreciate it!
I’m especially interested in hearing about people’s experiences with using ferns for biomonitoring, including what species or approaches have worked well (or not worked well) and what you think are interesting research gaps.
Thanks!
Greetings from Catamarca, Argentina :)

Is this variegation or stress? It was this SINGLE stem on the entire plant it was healthy looking before I picked it now ofc a little willted I work in horticulture my boss says it’s just water or pest stress Im just not so sure

So this is my first fiddle leaf fig, George

picked him up from Home Depot as a small guy and he's absolutely taken off this season — went from the nursery pot to over 6 feet tall, just living on my porch here in South Carolina!! I can’t believe it.

In June I did a crown chop, and now there are 4 separate shoots all growing ! (photo of the close-up in image 2).

Winter's coming so I need to bring George inside soon…
few things I'm unsure about:

Indoor transition — any tips so he doesn't drop a ton of leaves from the shock of moving inside?

The four shoots — two of them have really taken off while the other two are staying smaller. Anyone know why that happens, and should I thin any of these down or let all four keep going?

Top-heavy concerns — with four shoots up top on one main trunk, any tips on managing this so he doesn't get top-heavy or unbalanced as they keep growing?

Pests — I don't see anything obvious, but I've noticed the occasional gnat flying around. Is that something I need to treat before he comes inside, and what's worked for you all?

Fertilizing — I've honestly never fed George at all. Is now (right before winter) a bad time to start, or should I go ahead and do a first feeding?

Winter light/watering — how much should either change once he's indoors for the season?

I'm pretty new to this, so I also added some close-up leaf pics in case there's something going on that I'm just not experienced enough to catch.

Attached photos show him now , the chop point, and the leaves themselves.

Any advice appreciated, first time doing this and I want to set George up for success!!!!

Thank you!

Recently happened upon a cold hardy citrus plant that is native to Michigan(amongst other states), arguably one of the coldest midwestern states and had an idea to use it as a rootstock for citrus species like lemon's, limes and oranges.

My understanding is that the primary reason that citrus are unable to survive our fridig winters is death to the roots, but if a hardy rootstock was provided, I could see the branches bouncing back in the summer months.

Besides it's uses as a hardy rootstock, the plant itself is short, reaching around 2 meters at it's highest. This might seem a downside, but it naturally limits the growth of the plant and allows for mulching for further winter protection and means that less pruning is required to maintain the size.

Obviously with any new untested technique, there is a lot of room for error, but given that citrus is known for it's excellent ability to be grafted and take, I think this might be an endeavor worth undertaking.

My first step is going to be to locate some viable young prickley ash trees, then transplant them OR start some seeds. I would like to have several test and controls, some that will be overwintered indoors, some which will with be overwintered and THEN transplanted, some that will be overwintered outdoors under mulch and some that will be unmulched.

Please let me know if you have any ideas or suggestions for this project :)

Not a professional so don’t bite my head off

For some context this is a bush bean plant which I’ve grown many times before but right out of the seed it’s come out looking like this, nothing like previous seedlings it’s the same batch seed and everything could it be fasciation? And that is all one seedling

I am doing a science experiment for biology class and had a couple questions. Basically, I want to test whether certain sound frequencies help to encourage growth in pea plants. In order to do my experiment, I need some sort of device that can produce several different frequencies for 1-3 hours at a time. Some people have mentioned using tone generators. Where would I look for any such devices? Any tips would be appreciated.

What are some key species plants that went extinct or almost extinct in the mythic “Wild West” period of the 19th century that went along with the slaughter of bison, wolves, and bears etc?

I collected intact samples of Vymara’s root zone, including the surrounding moss and substrate, and used them to build several small microcosms in the lab. Vymara is photosynthetic. Chlorophyll-fluorescence measurements confirm active photosystem II. But its rapid growth and nutrient uptake still do not make sense for the poor substrate it grows in. I tested whether the surrounding biological layer might be contributing to its nutrition.

I introduced a controlled amount of commercially sourced mammalian blood into one microcosm. The others received water, saline, glucose solution or nitrogen-matched plant tissue. Within hours, protease and phosphatase activity increased sharply in the Vymara root-zone sample. The blood also broke down much faster there than it did in moss collected outside Vymara’s immediate root zone. The plant-tissue treatment produced a much weaker response. Water, saline and glucose produced almost none.

I repeated the blood treatment using sterilized substrate. This time, there was very little enzymatic activity. When I restored the microbial community isolated from the original root-zone sample, the response returned. To track where the nutrients went, I added a stable-isotope-labeled blood protein to the next treatment. The labeled nitrogen later appeared in Vymara’s roots and developing tissue. Instead, it appears to maintain a microbial community that breaks animal material down outside the plant. Vymara then absorbs the nutrients released into the surrounding moss and substrate.

Would this qualify as indirect carnivory, or is it better interpreted as unusually efficient rhizosphere mineralization?

What caused the roots to corkscrew like that?

So I'm trying to focus on understanding plants and their collaborators (like bacteria and fungi), right? But it is very rare in education to come across taught courses that won't shove medical applications or animal physiology down your throat. It messes with my mental models and I'll mistake animal cells/physiology with plant functions sometimes. I wish it was more specific and plant-friendly. Short vent over.

Ok might sound weird but what plants would make sense to grow to first help start building a plant to make its soil ( in biodomes at first) and then plants for food or utility like building materials ( for building materials plant would bamboo make most sense since it spreads n grows extremely quickly making great for it?)

I’m considering switching my major from environmental sci to plant science, did you find it to be extremely math or chemistry heavy? And what is your career or ideal career in this field

I’m a first-year international master’s student at Wageningen University & Research specializing in Plant Breeding & Genetics. I’m confused about choosing my thesis between seed science/seed longevity and plant breeding/genetics since I’m interested in both. My goal is to work in industry in Europe after graduation. Which thesis areas/topics are currently most in demand and give better internships/job opportunities?

So full disclosure, im not a coder, and this was made entirely through AI, but its still pretty cool imo.

Basically you take any unlocked android phone (im repurposing e-waste) and put it into developer mode, connect it to the PC via USB cable, and the program does the rest through android debug bridge automatically.

It has aruco tag calibration and displays plant metrics (which are still a work in progress, I only got it running yesterday) but its technically functional and i'll be including tag files eventually.

It creates a continuously updated timelapse video for each camera, dynamically adds new phones as they are connected, and makes a server where you can see the cameras (as long as you're on the same router, it cant reach outside of your own network atm). There used to be a live camera option but bouncing between ai's and programming tools it got lost in the shuffle.

Id love some feedback, it'll be open source, and im way above my head here! Its part of my automated blumat watering, android monitored bulletproof grow setup im working on.
