6-Benzylaminopurine yog ib qho hluavtaws cytokinin uas txhawb nqa kev faib tawm ntawm tes thiab cov khoom noj sib xyaw hauv cov hauv paus hauv av thiab cov qoob loo los ntawm kev tswj hwm cov txheej txheem kev noj qab haus huv ntawm cov nroj tsuag, yog li ua kom cov qoob loo thiab txhim kho zoo.
Cov txheej txheem uas 6-Benzylaminopurine txhawb nqa kev faib tawm ntawm tes hauv cov hauv paus hauv paus thiab cov qoob loo tubers feem ntau cuam tshuam nrog kev ua kom muaj kev nthuav qhia ntawm cov noob caj noob ces cuam tshuam thiab ua kom cov cell loj hlob ntawm meristematic. Hauv cov hauv paus hauv av thiab cov qoob loo xws li qos yaj ywm thiab yams, 6-BA tuaj yeem ua kom cov hlwb hauv tubers lossis rhizomes. Piv txwv li, thaum siv ua ke nrog Forchlorfenuron (CPPU), nws tuaj yeem nce cov qos yaj ywm tuber hlwb los ntawm 25% -30% thiab ib txhij nce qhov ntev ntawm kev loj hlob ntawm yam rhizomes los ntawm 20% -25%.
Nws cov txheej txheem ntawm kev ua muaj xws li inducing qhov sib txawv ntawm cov ntaub so ntswg undifferentiated thiab txhawb bud tsim, yog li stimulating txoj kev loj hlob ntawm cov kab mob hauv av.
Hais txog kev tsim cov khoom noj khoom haus, 6-Benzylaminopurine txhim kho cov synthesis ntawm cov khoom xws li cov hmoov txhuv nplej siab los ntawm kev tswj kev thauj thiab kev faib khoom ntawm cov khoom siv photosynthetic. Nws txhawb txoj kev hloov ntawm cov amino acids thiab suab thaj rau hauv paus system. Piv txwv li, hauv cov qos yaj ywm qab zib, nws tuaj yeem nce qhov feem ntawm cov khoom siv photosynthetic faib rau cov tubers mus rau ntau dua 70%, nce qhov hnyav ntawm cov tubers los ntawm 18% -22%. Nyob rau tib lub sijhawm, los ntawm kev sib xyaw ntawm chelated potassium thiab calcium, nws ua haujlwm ntawm cov hmoov txhuv nplej siab synthase (SS) thiab sucrose synthase (SPS), nce cov hmoov txhuv nplej siab ntawm qej qij los ntawm 15% -20%.
Daim Ntawv Thov Sijhawm: Rau cov qoob loo hauv av (xws li qos yaj ywm thiab qhiav), nws raug nquahu kom tshuaj tsuag thaum lub sij hawm tillering lig los yog thaum ntxov tuber o lub sij hawm los txhawb kev faib cov cell thiab cov as-ham.
Concentration Control: Qhov pom zoo pom zoo yog 5-8 g/L (piv txwv li, 5000-8000 mg/L). Cov concentrations ntau dhau yuav tsum tau zam kom tsis txhob muaj kev loj hlob ntau dhau los yog deformities.
