Nta ntawm INDOLE-3-BUTYRIC ACID (IBA): INDOLE-3-BUTYRIC ACID (IBA) yog ib qho endogenous auxin uas tuaj yeem txhawb kev faib cov cell thiab kev loj hlob ntawm tes, txhawb kev tsim cov hauv paus hniav, nce cov txiv hmab txiv ntoo, tiv thaiv cov txiv hmab txiv ntoo poob, thiab hloov poj niam thiab txiv neej paj Ratio thiab lwm yam. Nws tuaj yeem nkag mus rau hauv cov nroj tsuag lub cev los ntawm kev sib tw epidermis ntawm nplooj, ceg, thiab noob, thiab yog thauj mus rau lub active qhov chaw nrog rau cov as-ham.

Forchlorfenuron, tseem hu ua KT-30, CPPU, thiab lwm yam, yog cov nroj tsuag kev loj hlob regulator nrog furfurylaminopurine nyhuv. Nws kuj yog ib qho hluavtaws furfurylaminopurine nrog rau kev ua haujlwm siab tshaj plaws hauv kev txhawb nqa cell faib. Nws cov haujlwm lom neeg yog hais txog ntawm benzylaminopurine 10 zaug, nws tuaj yeem txhawb kev loj hlob ntawm cov qoob loo, nce cov txiv hmab txiv ntoo, txhawb cov txiv hmab txiv ntoo nthuav dav thiab khaws cia.

Thidiazuron (TDZ) yog urea cog kev loj hlob regulator. Nws tuaj yeem siv nyob rau hauv cov xwm txheej siab rau paj rwb, ua cov txiv lws suav, kua txob thiab lwm yam qoob loo. Tom qab absorbed los ntawm cov nplooj ntoo, nws tuaj yeem txhawb cov nplooj tawg thaum ntxov, uas yog qhov zoo rau kev sau qoob loo. ; Siv nyob rau hauv qis concentration tej yam kev mob, nws muaj cytokinin kev ua si thiab yuav siv tau nyob rau hauv txiv apples, pears, txiv duaj, txiv duaj, cherries, watermelons, melons thiab lwm yam qoob loo kom nce txiv hmab txiv ntoo tus nqi, txhawb cov txiv hmab txiv ntoo o, thiab nce yield thiab zoo.

Brassinolide (BR) txawv ntawm lwm cov nroj tsuag kev loj hlob regulators nyob rau hauv nws ib-txoj kev lub hom phiaj nyob rau hauv txhawb cov qoob loo tawm los thiab txhim kho zoo. Piv txwv li, nws tsis tsuas yog muaj lub zog physiological ntawm auxin thiab cytokinin, tab sis kuj muaj peev xwm ua kom photosynthesis thiab tswj cov khoom noj khoom haus, txhawb kev thauj cov carbohydrates los ntawm stems thiab nplooj mus rau cov nplej, txhim kho cov qoob loo tiv thaiv sab nraud, thiab txhawb kev loj hlob ntawm qhov tsis muaj zog ntawm cov nroj tsuag. Yog li ntawd, nws muaj ntau heev usability thiab practicality.
