Learn How Pine Trees Reproduce | Gymnosperm Life Cycle

Have you ever wondered about those orange clusters that appear on conifers (pine trees in this case) in spring? And how come there are no flowers but a lot of pollen coming off of pine trees? We explain how pine tree (gymnosperm) reproduction works through simple observations and exploration!

[@nikhilranjan171]

You alone made me understand in 4 minutes 20 seconds what tens of teachers through out my school & colllege could not. Before today I used to think of myself as dumb but now I know who is.

Thank you for taking time to write this comment! It means a lot to me to hear that this style of explanation is working!😊 I've had a similar experience throughout my education and that's why I'm trying to do it differently!

[@pawanpt2682]

I agree

[@simonb.jensen7825]

It's crazy to me you had 10 different teachers trying to teach you this topic! I didn't even have one. Jokes aside, I agree. It's a really great video!

[@laurazollo3493]

Thank you for this video. We haven’t tried the experiment yet, but I used this video as a tool to help educate my four year old daughter who for some reason is terrified of pinecones! 😮 She understands now that pinecones are just part of how conifers reproduce. Yay pinecones!🎉

[@dr.smakbiology4933]

Thank you for sharing your video! I teach an online class for Biology 2, and after I discuss the Pine Life Cycle with textbook images, I really wanted to show my students the actual pine pollen cones and ovulate cones. So I appreciate you showing those burst of clouds of pollen! I actually did do your experiment with the pine cones I had picked up from a camping trip a few years ago (I use them as decorations). I can't believe it still works with old pine cones! I left the cone in water for about an hour or so, it closed up to almost 1/3 of its size! It made my day. As a scientist and biologist, nothing beats doing a simple cool experiment! I appreciate it!

[@chrisgoldbach4450]

Epic man. I'm wondering now about germination process and methods, cold stratification, plus the difference between seeds and nuts after finding a big cone in California by point dume with nuts instead of seeds I think.

[@natureclearly]

Hi Chris! Although majority of pines have winged seeds, seeds of some species are large and not winged and you might think of them as nuts. Inside of the hard shell of these nuts is a seed. One good example would be pinyon pine. These types of seeds rely on animal dispersal, rather than wind. Seed stratification and germination is a great topic and I'll be talking about it in a video I'm preparing for this spring. Stay tuned! :)

[@chrisgoldbach4450]

@@natureclearly I'm that animal then haha I found a huge cone in California then happened to knock some nuts out. Trying to germinate them now but it seems like nothing's happening in the wet paper towel. Cant wait! You know your stuff thank you

[@GuilleFunes_]

Awesome. Thanks for the coold video. Do you know how long can the female cone be in the tree? And, during that time, the female cone opens and closes constantly?

[@stuartwells4133]

I went out a few years ago collecting Pine Cones in a plastic bag. When I got them home I put them all into the sink to wash all the dirt off. They quickly closed up so I left them on a window sill and after about a week the Pine Cones had started to open back up. And yes there will be very small seeds inside the Pine Cone.

[@natureclearly]

Thank you! What part of the process would you like to know in more detail?

[@ashleymarie1288]

How long do they take to close up in water?

[@chelseacooper4319]

Is there a certain time of year to try this experiment? How long did it take for yours to close when submerged?

[@natureclearly]

Hi, Chelsea! Any time of the year when you can find the cones on the ground is good. When it's been dry for a few days, you'll get nicely opened cones (make sure you're picking up mature cones). It usually takes about a couple of hours or more for the cone to close, but each cone is little different, depending on its size, age, etc. Let me know how your experiment goes, if you try it! :)

[@dmitrimikrioukov5935]

I grew 5 conifer species at home from cone seeds, including 3 species of pine.

[@natureclearly]

That's cool! How big are they now?

[@dmitrimikrioukov5935]

@@natureclearly Only 2 have survived... 1 larch about 2 or 3 feet tall. 1 Siberian pine around 3 or 4 inches tall. I knew Siberian pines were very slow growers. But... Like literally 1 cm a year... I heard the reason is that in nature they grow in extreme cold where summers are very short, so they are careful not to fall victim to sudden early or late frosts.

[@scottwebber652]

Is there a way to harvest seeds from the black hills spruce ? Education needed

[@natureclearly]

Are you able to harvest the cones of the tree? If so, I recommend harvesting mature cones when they are closed (when it is moist outside), then taking them home and placing them into a paper bag. Once the cones are dry, they will open and release the seeds. Let me know how that goes! :)

[@scottwebber652]

@@natureclearly got it except I want you to explain when is the cone mature. No sap or green color but before they open up much n moist out ?

[@scottwebber652]

@@natureclearly I did try ur technique with some last year’s still hanging n I did get some.

[@natureclearly]

@@scottwebber652 You're right, the cone should not be green, that would be too early for harvesting seeds. I've had the biggest success harvesting seeds from cones that are mostly closed but slightly open at places (check out the video at 3:50, the cones showed there were bursting with seeds!). To have some comparison, the closed cone shown in the video at 3:57 never opened! You need to get it just right and that might take some guessing and multiple cones!

[@diggumsmack2]

I have a question ⁉️ Actually two. Once a female cone is pollinated, is the whole tree thus pollinated? Does the pollen need to find a female cone every year or once pollinated, the tree produces seeds for the rest of its life?

[@diggumsmack2]

Oh! and can a trees male pollen pollinate it's own female cones? So many questions!!!!!

[@natureclearly]

You can think of every cone as a separate "unit". Every cone needs to get pollinated separately and on one tree, you can find cones at different life stages. New cones are produced every year and to produce seeds, they need to get pollinated by pollen from "fresh" male cones. Does this answer your question?

[@natureclearly]

Yes! It can happen, but pine trees have a way to avoid (or at least minimize) self pollination. Male cones grow mainly on the lower part of the tree, whereas female cones grow higher up. That way, when the pollen blows in the wind, it goes away from the tree, not reaching the female cones on the same tree. Next time you see a pine tree, take a look if you notice the female cones clustered higher up in the tree! 😉

[@shanthala1345]

Wow make more videos

[@natureclearly]

More videos coming soon!

[@WilliamHollinger2019]

I am here due to a neighbor who wants his trees to be cut down they were in my childhood. Yeah I get with injuries but not the healthy ones. So I am on a small mission to find small pine trees or seeds that I can let my backyard to take off.

[@danthomas6587]

It's confusing I think to describe the male structure as a "cone". When I learned taxonomy in school the male structure of a White Pine was called a catkin. Other woody plants have catkins as well, like Birch. Maybe the words are interchangeable. Maybe I'm just splitting hairs. Cheers from Tucson Arizona.

[@fainabikmurzina2646]

If you dive deep into details, male and female cones of _some_ Gymnosperms are not the same. While male cone is a strobilus (a stalk with scales on it), the female cone is a constrobilus (basically the strobilus but with another strobila instead of scales). Female cones also have 2 kinds of scales which have different origination, while male cones have only one type of scales. Anyway, it is absolutely correct to say that Gymnosperms have male and female cones.

[@danthomas6587]

@@fainabikmurzina2646 wow...that's pretty technical but I'm such a plant nerd I enjoyed reading. Can I bore you with a short story? While doing some landscaping years ago I made a $1000 wager with a guy who worked with me that he couldn't tell me the correct name of the female fruiting structure on southern magnolia. As you know its a beautiful ornament on Southern Magnolias mostly north of Florida. He spent a week, he called the Pennsylvania Horticultural Society, ( I never saw that coming) he read everything he could find and threw his hands up when all he came up with was "cone". Maybe I set the bar too high. The name i learned was gynoecium from Michael Dirr's manual, but because his efforts impressed me I paid him half. His wife had just had a baby girl.
