Heya

I'm looking for a book that will help me identify wild flowers on my allotment and beyond. I would particularly like to distinguish with confidence the Apiaceae family members. I live in South of UK. Could you tell me what are your thoughts on these? :

• "The Wildflower Key" Francis Rose
• "Collins Wild Flower guide" David Streeter
• "New Flora of the British Isles" Clive Stace
• "The Vegetative Key to the British flora" John Poland

These trees look pretty different, but I can never remember which is which! To me, it feels like the prefix pseudo- would mean something very similar to the suffix -ides. Is this just a historical nomenclature accident, or do they have systematic meanings?

I am starting a vegetable garden from seeds for the first time and did not realize that I should not have my grow lights on 24/7.

I have been reading up the effect of continuous light, which has led me to the question of, do plants (such as your average garden variety, tomatoes, peppers, cucumbers, onions as well as some things like, marigolds, mint and lavender) actually need a dark period? What is the effect of excessive light? Is there such a thing as excessive light? Something I was reading was discussing how dark periods can potentially help free radicals, but was not commenting on the necessity of.

I am genuinely curious of the effects of this mistake. I am talking to my geneticist friend who is slightly into botany, and told me to course correct be decreasing the light period for an hour a day until I get to a 12:12 schedule as to not shock them and prepare them for the outside , so I will move forward with that.

My other friend who helped me plant these seeds has very different looking plants than I. Mine are massive and (appear) to be thriving, while hers (from following an 16:8 cycle) seem to be struggling and/or more stunted. Our seed trays are wildy different and we are rather curious to know about the science and potential effects from our accidental experiment.

I am not a scientist, but things that I am reading for insight currently include,

Effects of lighting time and lighting source on growth, yield and quality of greenhouse sweet pepper

The Power of Far-Red Light at Night: Photomorphogenic, Physiological, and Yield Response in Pepper During Dynamic 24 Hour Lighting

Effects of supplemental light duration on greenhouse tomato (Lycopersicon esculentum Mill.) plants and fruit yields

I am currently planting native grass seed and it got me thinking. Most of the information you will find for simpletons like me is that seeds in general will need to remain moist throughout germination and without properly keeping them moist 100% of the time they will die. I'm in Colorado so it got me thinking, how true is this really? How do seeds in the plains and mountains germinate in my dry climate? It seems like I should just be able to drop seeds into the dirt and they would grow like they do throughout the plains all around me. Obviously at a slower and more inconsistent rate. I do understand they need water like all life.

I am a university student in the US and I have always been super interested in Botany. Unfortunately my university did not have a Botany or plant sciences program so I began studying Horticulture. Now I am about a year from graduating with my bachelor and am planning on starting my masters next semester (my school allows a year overlap). I am definitely starting to realize how different the two programs would be and am kind of worried it is going to affect my career options substantially. I would love to work a research position studying plant-microbe interaction, plant genetics, wildlife population, or something along those lines. My degree is focused mostly on plant production, and I have class mostly center around that. How would you recommend I bridge that gap? Can I do some personal study or are employers going to be looking for school study? I am doing research with a professor right now but it is definitely more on the horticulture side. Now I’m kind of worried I’m wasting some of my time in university.

I rarely see fluff mixed in with flowers or vice versa when looking at a yard full of dandelions. How do they all know it’s time to change?

Freak in my yard!!!

New research indicates that secondary metabolites involved in growth and development arise from a more dynamical and complex scenario mediated by HGT, which directly conflicts with the putative opinion of VGT, which posited that genes are inherited from ancestral lineages. Furthermore, the underlying mechanisms by which HGT exerts its effects are mainly through gene transfer.

Coming to my questions, how prevalent is HGT in the evolutionary history of lineages? Did HGT events involving genes for secondary metabolite biosynthesis occur frequently, or were they chiefly rare or sporadic? Can we identify specific instances where HGT shaped the chemical profile of a particular group?

there’s dead dandelions clumped together in my yard and no, it’s not fasciation; it’s bottom part of the stem is fused together and it looks like tentacles i hate it and it’s creepy i need help what it is.

Hello everyone,

I’m a young plant scientist studying the growth of a plant species. This plant is a rosette plant which is known to have foliage breakdown. As foliage breakdown is very important I would like to monitor it. I want to do this by numbering the leaves of the rosette. How can I number the leaves during the growing season? All suggestions are welcome :)

Thank you a lot !

There’s this plant called Seep Monkey Flower (Erythranthe guttata) that starts its early stages of life underwater, and then once the water level drops and the plant reaches the surface, it starts to flower and go to seed. Weeks after the water has dried up, the plant is still flowering and growing and looks completely different than its once aquatic version. Is there a specific term for this growth habit?

Howdy, we have a mature northern catalpa tree on my in laws property, and there’s a lot of sentimental value to it. I’m trying to gauge the age of it, and I know the circumference at 4.5 feet is 168 inches. Would anyone happen to know what the growth factor would be for that species? Thanks!!

Or just some really good diagrams in general would help loads, thanks!

Found this sweatshirt at the thrift store and am wondering how accurate it actually is. I'm not a botanist by any means, so I wanted to see if y'all can spot anything amiss that I might miss.

This is what I've managed to catch:

-Capitalizing the M in "Amanita Muscaria" (I think species names are supposed to be lowercase if I remember correctly)

-Use of taxonomy names vs. common names is inconsistent

-Level of taxonomical (is that a word?) identification is inconsistent (ex. Amanita muscaria and Crocus speciosus are identified at species level while Clover and Lavender are only identified at the genus level)

-The plant with the big root and orange flowers(?) in the middle is not identified (does anyone know what that is?)

Is there anything I missed that y'all can think of? I don't know plants well enough to judge the accuracy of the illustrations.

And would you judge someone for wearing this sweatshirt if they're not a bontanist? I've never studied botany and only recently got into gardening so I don't know a ton about plants. I'm worried I'll either be laughed at or spontaneously quizzed on plant facts if I wear this thing out in public so I'm debating whether I should return it. But maybe I'm just being paranoid.

(Also apologies for weird formatting - I'm on mobile)

One of my assignments for my botany course is to collect plants to produce a herbarium, and one of the required plants is the Chorleywood. I was wondering what these spots on the leaves are. Any help? Thanks!

I am looking for a book or guide containing basic info about different plants and their uses, which ones are poisonous and so on. I basically would like a beginner's guide. What would you recommend?

PS. I didn't find a better tag.

Suppose I have a plant that flowers when the dark period is a certain length. If in summer, I cover a branch in light-blocking material, and illuminate it weakly with some LEDs at a 12/12 light cycle (just enough lighting to signal the plant to keep the branch alive), could I get it to flower and produce fruit?

Would the photosynthesis from the uncovered branches delivery nutrients to the covered branch?

I'm currently on a hike with a fuck ton of poison oak. I'm nervous about it hurting my dog so I'm keeping her in a heel the whole time and have to remain super vigilant, which isn't fun for either of us. Will it seriously harm her? One article I read said take dogs to the vet immediately but I know the Internet is full of misinformation. Or can I be a little more relaxed as long as she doesn't eat any? I'm wearing pants and boots so I'm not super concerned about me.

Thanks!

I'm doing a research project on Oxalis triangularis. I'm finding conflicting information online about what the tuber-like structure is. Is it a tuber? Rhizome? Bulb?

https://www.researchgate.net/publication/236694370_Synthetic_Seeds_Production_and_Regeneration_of_Oxalis_triangularis_for_Mass_Propagation_and_Conservation

I also read here that Oxalis triangularis doesn't naturally produce viable seeds, is this true? Isn't that a key characteristic of angiosperms? If it solely relies on the subterranean structure to reproduce asexually, then what is the point of the flowers?

Thanks in advance

With plants most people don't mention the role of acid growth and I get into why that's important with microgreens.

I have a shot of my spectroradiometer showing chlorophyll fluorescence which is how I can measure photosynthesis efficiency. I show my little light profiling setup using 6 two gallon buckets as grow chambers

At the bottom are some useful notes and links to about 30 peer reviewed papers. The peer reviewed literature for a range of plants is showing that far red light may actually reduce yields which is the opposite of what has been though for decades.

I make an argument of why one might want to experiment using lower color temperature lights rather than the more common 6500K lights with microgreens.

Looks like the Forestry Suppliers and Herbarium Supply are on back order or out of stock for the canvas field press, does anyone know another place to get one? TIA I’m in the USA.
