Hormon adalah pembawa pesan kimiawi yang disintesis di suatu bagian untuk dikirim ke bagian lain. 5 jenis hormon utama yang mempengaruhi pertumbuhan tumbuhan 1. Auxin Auxin adalah hormon yang memungkinkan tumbuhan untuk bengkok ke arah cahaya (disebut juga fototropisme). Tropisme adalah pergerakan suatu organisme karena adanya rangsangan eksternal. Hormon auksin diproduksi di ujung batang dan bergerak ke bawah, oleh karena itu jika kita memotong ujung batang, tumbuhan akan kehilangan kemampuannya untuk tumbuh ke arah cahaya. 2. Giberelin Hormon giberelin sangat penting pada beberapa tahap perkembangan tumbuhan. Secara singkatnya hormon ini dibutuhkan tumbuhan untuk berkecambah,regulas dan membantu regulasinya, mempercepat perpanjangan internodus (batang yang terletak diantara ruas) yang merupakan tempat daun-daun tumbuh. 3. Sitokinin Hormon sitokinin mencegah tumbuhan dari penuaan. Hormon ini juga berperan penting dalam menghasilkan organ tumbuhan baru (root-shoot), diproduksi di meristem apikal akar atau ujung akar serta terbawa bersama air melalui jaringan xilem secara tidak langsung. Tumbuhan menggunakan rasio auksin dan sitokinin untuk menentukan pembentukan ke arah bawah (root) atau ke arah atas (shoot). Kelebihan auksin mendukung pembentukan ke bawah (root), sedangkan kelebihan kelebihan sitokinin mendukung pembentukan ke atas (shoot). Sitokinin juga bekerja sama dengan hormon yang akan dibahas berikutnya. 4. Etilen Etilen dibutuhkan untuk proses abscission daun, bunga atau buah. Etilen adalah hormon yang dapat merangsang pemasakan. Jika buah masak disatukan dengan buah lainnya yang belum masak, buah tersebut akan masak lebih cepat. Etilen adalah gas dengan daya larut rendah dalam air yang terdifusi keluar dari sel dan sebagian besarnya dihasilkan oleh sel yang tumbuh dan membelah dengan cepat. Ini penting untuk tanaman yang berkecambah karena produksi hormon etilen yang tinggi akan menghambat perkembangan daun. 5. Asam Absisat Asam Absisat adalah hormon yang menandakan dehidrasi. Hormon ini disintesis di kloroplas pada daun saat tumbuhan stres air, bergerak melalui xilem dan floem dan menyebabkan daun menutup stomata untuk mengurangi kehilangan air dari fototranspirasi. Itulah lima jenis hormon yang mempengaruhi pertumbuhan tanaman, meskipun masih banyak hormon yang lainnya.
I litterly learned a lot with this channel in very less time . Thank you from the bottom of my heart and I wish this channel will surely reach more subscribers.
This lectures was done 5 years ago and i hope you're still making more lecture videos. Im from Nigeria and i enjoyed your lecture. I just hope you're still in the system of doing this.. bless you greatly❤❤
De novo abscisic acid (ABA) synthesis is initiated in plastids via the oxidative cleavage of xanthophylls. The cleaved product xanthoxin moves to the cytoplasm and is modified further in the cytoplasm to produce ABA. ABA is inactivated through multiple pathways either by oxidation or conjugation. Glucose-conjugated ABA (ABA-GE) and phaseic acid (or it's reduced form dihydrophaseic acid) are the major inactive forms of ABA. Lee et al. (2006)demonstrate that the intracellular β-glucosidase AtBG1 cleaves ABA-GE to produce ABA as a new route of ABA production under osmotic and drought stress conditions and during day/night cycles. The activity of AtBG1 is enhanced by the polymerization of this enzyme, which is induced by these environmental factors. Therefore, the cleavage of ABA-GE is proposed as an alternative route for rapid ABA synthesis in response to changes in stress and light conditions.
More auxins promotes more roots? I thought the opposite. I thought cytokinins produced more roots and auxins promoted shoots? Could you explain any further?
1:25 if the plant has 5 petals doesnt that mean its dicot and should have a taproot system i am not tryna point out a mistake i just wanna see if im kinda smart and actually know some stuff lol
Does anyone know how to extract and detect (maybe with chromatography...?) the auxin, gibberellin, and cytokinin levels of the plant with common high school laboratory apparatus? I think I could do the avena curvature test for auxin... but I'm wondering how to get quantitative data on the IAA amount. Thanks.
Hello I'm looking for information regarding slowing down the growth of large hedges for some of my customers I really hope that you can share some information on UA-cam about this and how it works
Fast narration.let it be slow for the sake of students. More videos on individual topics on harmones for the benefit of students. Thank you very much for your help.
Noted! Thank you very much for the suggestions. I will attempt to make the narration slower in future videos and will try to make more videos on plant hormones :-)

That was two lectures condensed into 3 minutes, super helpful!
It's like the lectures are just throwing facts without giving explanations
Same
I love a video that is short and to the point. Thank you for this!!

Thanks ... direct and to the point. Much easier for my students to follow.
Nice video! 🎉
The video is just amazing.... I loved it, it explained me the points I was unable to understand... Thanku so much😊😊
So glad it was helpful for you! :-D :-D :-D
short and clear explanation!! Great stuff my teachers can't even teach this properly in university
This lectures was done 5 years ago and i hope you're still making more lecture videos. Im from Nigeria and i enjoyed your lecture. I just hope you're still in the system of doing this.. bless you greatly❤❤
This is really helpful! Thanks! I love you pictures as well.
Really great quick review of the plant hormones! Love it!
Thank you so much! I'm glad you like it!
Really helpful. You covered a lot of thing in just 3 minutes
Sahi ha
Life is like 3 mintues of smell of girls passing by on trains and thats smell goes away and we die from condom war

How to use it is by irrigation or spraying for each hormone, please.
Good explanation
More auxins promotes more roots? I thought the opposite. I thought cytokinins produced more roots and auxins promoted shoots? Could you explain any further?
Same question.
it does
Thanks for yours kind video clips
awesome! Which of these is relevant for cannabis? Anyone used these on cannabis?
thank you so much this video is amazing
Excellent mam

Straight to the main points makes easy 😉😉😉

super video
*Amazing!!!! Thanks for the info !!!*
Great content. Any experience with reversing the sex of female plants to produce pollen?
Amazing💜💜
What program did you use to make this video?
Thank you!
V Nys informative video .... plzz give a video about cribs cycle c3 c4 and cam pathway....thnku
I put it on my to do list :-)
I have covered the C4 pathway though! ua-cam.com/video/Lhd7WbWV8aw/v-deo.html

do you know if there is any ethylene qualitative indicator or ethylene tablets available?
Great👍👍
Tq
thanks for sharing this video
anyone else sent here by their science teacher

Tips how to love science?😭😓

Where do plant hormones specially come from?
Is it for class 11??
It is for 10
🙏🙏🙏
I came here because my teacher told me to
😔😔
I m not able to understand the human anatomy and physiology chapters
Please check out my videos - I have a few videos on anatomy. Are there any other anatomy topics you would like me to cover?
is this ms. Shire
Nope
