Kev ua haujlwm ntawm Brassinolide (BR)
Brassinolide (BR) yog ib qho dav-spectrum thiab muaj txiaj ntsig kev loj hlob ntawm cov nroj tsuag. Nws tau tshawb pom los ntawm Asmeskas cov kws tshawb fawb txog kev ua liaj ua teb hauv xyoo 1970 thiab lub npe hu ua brassinolide, brassinolide yog hu ua thib rau hom tshuaj hormones vim nws cov tshuaj me me thiab muaj txiaj ntsig zoo.
Brassinolide (BR) ua dab tsi?
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.
1. Sweetening thiab xim
Kev siv Brassinolide (BR) tuaj yeem ua kom qab zib qab zib thiab nce qhov feem ntawm cov nplooj ntawv qib nrab thiab qib siab. Siv nws ntawm citrus tuaj yeem txhim kho qhov tsis xws luag xws li tawv tawv, caws pliav, txiv hmab txiv ntoo crooked, thiab lignification tshwm sim los ntawm kev txau gibberellins. Lychees, melons, thiab lwm yam. Siv taum, nws tuaj yeem ua rau cov txiv hmab txiv ntoo sib xws, txhim kho cov tsos, nce tus nqi muag thiab nce nyiaj tau los.
2. Ncua nplooj senescence
Nws khaws ntsuab rau lub sijhawm ntev, ntxiv dag zog rau chlorophyll synthesis, txhim kho photosynthesis, thiab txhawb cov nplooj xim kom tob thiab tig ntsuab.
3. Txhawb paj thiab khaws cov txiv hmab txiv ntoo
Siv thaum lub sij hawm flowering theem thiab cov tub ntxhais hluas txiv hmab txiv ntoo theem, nws muaj peev xwm txhawb paj thiab txiv hmab txiv ntoo thiab tiv thaiv cov txiv hmab txiv ntoo poob.
4. Txhawb nqa cell faib thiab loj hlob txiv hmab txiv ntoo
Nws tuaj yeem pom tseeb txhawb kev faib cov hlwb thiab txhawb txoj kev loj hlob ntawm kab rov tav thiab ntsug ntawm lub cev, yog li ua kom cov txiv hmab txiv ntoo loj tuaj.
5. Ua kom ntau lawm
Ua kom zoo dua sab saum toj thiab txhawb cov germination ntawm lateral buds tuaj yeem nkag mus rau qhov sib txawv ntawm buds, txhawb kev tsim ntawm lateral ceg, nce tus naj npawb ntawm cov ceg, nce tus naj npawb ntawm paj, txhim kho paj ntoos fertilization, yog li nce tus naj npawb ntawm cov txiv hmab txiv ntoo thiab nce ntau lawm. .
6. Txhim kho kev lag luam ntawm cov qoob loo
Induces parthenocarpy, tiv thaiv paj thiab txiv hmab txiv ntoo poob, txhawb nqa protein synthesis, nce qab zib cov ntsiab lus, txhim kho qoob loo zoo, thiab txhim kho kev lag luam.
7. Tswj thiab sib npaug ntawm cov khoom noj khoom haus
Brassinolide (BR) tsis yog foliar chiv thiab tsis muaj kev noj haus zoo, yog li kev sib xyaw ntawm foliar fertilizer ntxiv rau brassinolide yog qhov tshwj xeeb tshaj yog siv. Foliar fertilizer tuaj yeem ntxiv cov nroj tsuag cov as-ham, tab sis nws tsis muaj peev xwm sib npaug thiab tswj kev thauj khoom noj khoom haus; Brassinolide (BR) tuaj yeem thauj cov as-ham hauv qhov sib npaug, tso cai rau kev coj noj coj ua ntawm cov zaub mov, kom cov qoob loo loj hlob thiab kev loj hlob ntawm cov qoob loo tuaj yeem tau txais cov as-ham tsim nyog.
8. Sterilize thiab ua kom muaj txiaj ntsig zoo, rov ua kom txoj kev loj hlob sai
Cov fungicides tsuas tuaj yeem txo cov kab mob tab sis muaj kev cuam tshuam me me rau kev rov ua kom cov qoob loo loj hlob. Brassinolide tuaj yeem sib npaug kev thauj khoom noj khoom haus, txhawb nqa hauv paus nqus, thiab txhawb nqa photosynthesis. Yog li ntawd, thaum cov fungicides sib xyaw nrog brassinoids, lawv qhov zoo yog ua tiav. Brassinolide (BR) pab kho kab mob thiab muaj txiaj ntsig zoo rau cov qoob loo rov qab thiab kev loj hlob.
9. Txias tsis kam, Frost tsis kam, drought tsis kam thiab kab mob tsis kam
Tom qab Brassinolide (BR) nkag mus rau hauv cov nroj tsuag, nws tsis tsuas yog txhim kho photosynthesis thiab txhawb kev loj hlob thiab kev loj hlob, tab sis kuj muaj kev tiv thaiv tshwj xeeb ntawm cov nroj tsuag cell membrane tiv thaiv kev puas tsuaj ib puag ncig. Nws kuj tseem tuaj yeem txhawb nqa kev ua haujlwm ntawm kev tiv thaiv enzymes hauv cov nroj tsuag, txo cov tshuaj phem heev. Kev puas tsuaj rau qhov qub kev loj hlob ntawm cov nroj tsuag thiab comprehensively txhim kho cov kev ntxhov siab tsis kam ntawm cov qoob loo.
Cov kev sim tau ua tiav ntawm mov, dib, txiv lws suav, luam yeeb, thiab lwm yam, thiab cov txiaj ntsig yog:
1) Tsawg kub:
Txau Brassinolide (BR) tuaj yeem ua kom cov noob qoob loo ntawm ntau hom nplej los ntawm 40.1% nyob rau hauv qis kub. Nws physiological muaj nuj nqi ntawm kev txhim kho txias tolerance ntawm mov yog mas manifested nyob rau hauv kev txhim kho lub physiological metabolism ntawm mov thiab txhawb kev loj hlob thiab kev loj hlob ntawm lub cev nqaij daim tawv. Cov nroj tsuag kho nrog Brassinolide (BR) tau txhim kho qhov ntsuas kub ntawm lub cev nyob rau hauv qhov ntsuas ntawm 1 txog 5 ° C.
2) Kub kub:
Daim ntawv thov ntawm Brassinolide (BR) tuaj yeem ua rau kom cov nplooj chlorophyll thiab cov ntsiab lus ntawm cov protein ntau, superoxide dismutase (SOD) thiab peroxidase (POD) cov dej num ntawm cov nplej kub-rhiab heev.
3) ntsev-alkali:
Cov noob kho nrog Brassinolide (BR) tseem tuaj yeem tswj tau qhov kev loj hlob siab hauv 150 mmol NaCl ib puag ncig. Tom qab Brassinolide (BR)-kho cov nroj tsuag barley tau tsau rau hauv 500 mmol NaCl rau 24 teev, kev tshuaj xyuas ultramicroscopic pom tias cov qauv ntawm barley nplooj tau tiv thaiv.
4) Drought:
Cov qoob loo xws li qab zib beet kho nrog Brassinolide (BR) loj hlob zoo dua li pawg tswj hwm hauv ib puag ncig drought.
5) Kev tiv thaiv kab mob:
Brassinolide (BR) tuaj yeem txo qhov kev puas tsuaj los ntawm qee yam kab mob, xws li nplej sheath blight, dib grey pwm thiab lws suav lig blight. Hais txog kev haus luam yeeb, nws tsis yog tsuas yog txhawb kev loj hlob ntawm kev haus luam yeeb, tab sis kuj muaj kev tswj hwm ntawm 70% ntawm cov kab mob luam yeeb mosaic. Nws yog tus neeg sawv cev zoo tshaj plaws rau kev tiv thaiv thiab kho cov kab mob luam yeeb mosaic. Cov kab mob tsis kam ntawm cov nroj tsuag yog tswj los ntawm cov noob ntawm cov nroj tsuag nws tus kheej. Txawm li cas los xij, Brassinolide (BR) ester tuaj yeem tswj hwm cov txheej txheem physiological thiab biochemical ntawm cov nroj tsuag, yog li txo tus kab mob. Nyob rau tib lub sijhawm, raws li cov tshuaj hormones cog, Brassinolide (BR) tuaj yeem ua rau muaj kev tiv thaiv qee yam. Kev qhia ntawm cov noob kab mob txhim kho cov kab mob tiv thaiv ntawm cov nroj tsuag.
10. Txhawb kev loj hlob ntawm cov noob
Thaum siv los ua kev kho cov noob los yog txau ntawm cov yub theem, Brassinolide (BR) ua lub luag haujlwm txhawb kev tsim cov hauv paus hniav.
11. Yield-nce nyhuv
Cov ntaub ntawv tshawb fawb tshawb fawb pom tau tias tom qab siv brassinolides, cov nplej tuaj yeem nce ntxiv los ntawm 5.3% ~ 12.6%, cov pob kws tuaj yeem nce ntxiv los ntawm 6.3% ~ 20.2%, melon thiab zaub ntau lawm tuaj yeem nce 12.6% ~ 38.8%, txiv laum huab xeeb nce 10.4% ~ 32.6%, thiab cov suab thaj ntau lawm tuaj yeem nce los ntawm 9.5% ~ 18.9% (cov ntsiab lus qab zib nce 0.5% ~ 1%).
12. Txo cov tshuaj phem
Cov tshuaj tua kab mob, kev siv tsis raug ntawm cov tshuaj tua kab mob fungicidal, lossis qhov tsis tsim nyog concentration piv tuaj yeem ua rau phytotoxicity. Kev siv raws sij hawm ntawm Brassinolide (BR) ntxiv rau cov tshuaj foliar zoo tuaj yeem tswj cov khoom noj khoom haus, ntxiv cov khoom noj khoom haus, thiab txo cov qoob loo puas tsuaj los ntawm kev siv tshuaj tsis raug, ua kom cov qoob loo rov qab thiab kev loj hlob.
Brassinolide (BR) ua dab tsi?
