Dab tsi yog qhov kev ua haujlwm ntawm lub cev thiab kev siv ntawm gibberellins?

1. Gibberellin Txhawb nqa cell faib thiab sib txawv. Mature hlwb loj hlob longitudinally, elongating txiv hmab txiv ntoo stalk thiab thickening lub tev.
2. Gibberellin Txhawb lub biosynthesis ntawm auxin. Lawv muaj kev sib koom ua ke thiab muaj qee yam tshuaj tua kab mob.
3. Gibberellin tuaj yeem ntxias thiab nce qhov feem ntawm txiv neej paj, tswj lub sijhawm paj, thiab tsim cov txiv hmab txiv ntoo tsis muaj noob.
4. Gibberellin tuaj yeem elongate cov hlwb internode, uas tsis muaj kev cuam tshuam rau cov hauv paus hniav tab sis muaj kev cuam tshuam rau stems.
5. Gibberellin tiv thaiv lub cev los ntawm kev poob thiab tawg dormancy, thiab khaws cov paj thiab txiv hmab txiv ntoo.

Tsis tas li ntawd, peb tau sau 10 daim ntawv thov cov ntsiab lus:
1. Gibberellic acid tsuas tuaj yeem elongate hlwb thiab tsis tuaj yeem siv los hloov cov chiv.
2. Gibberellic acid yog acidic thiab tig liab thaum raug sulfuric acid. Nws tsis tuaj yeem sib xyaw nrog cov tshuaj tua kab alkaline.
3. Gibberellic acid tuaj yeem yaj hauv cawv. Nws yuav decompose yooj yim tom qab nkag mus rau hauv dej thiab tsis tuaj yeem tso tseg rau lub sijhawm ntev.
4. Cov kub hauv qab 20 degrees yuav cuam tshuam rau kev ua haujlwm ntawm gibberellic acid.
5. Gibberellic acid txawv ntawm auxin thiab yuav tsis cuam tshuam kev loj hlob ntawm cov concentrations siab.
6. Lub paj, cov hauv paus hniav, txiv hmab txiv ntoo thiab cov noob ntawm cov nroj tsuag muaj gibberellic acid, yog li nws nyuaj rau cov txiv hmab txiv ntoo uas tsis muaj noob nthuav.
7. Gibberellic acid tuaj yeem thauj tau ob qho tib si, nce thiab nqis. Kev siv ntau dhau yuav ua rau muaj kev loj hlob ntau dhau.
8. Kev loj hlob ntau dhau los ntawm gibberellic acid tuaj yeem txo qis los ntawm paclobutrazol.
9. Gibberellic acid tuaj yeem txau, thov rau cov noob hnav khaub ncaws thiab hauv paus dipping.
10. Gibberellic acid tuaj yeem ua haujlwm zoo dua thaum siv nrog rau lwm cov regulators thiab cov as-ham.
