24-epiBrassinolide Brassinolide 90% Tc cog Hormone

24-EpiBrassinolide tuaj yeem siv dav hauv kev ua liaj ua teb, xws li txhawb kev cog qoob loo thiab kev loj hlob, nce qoob loo, thiab txhim kho cov txiv hmab txiv ntoo zoo.

(1) Txhawb nqa cell elongation thiab faib

Kev kho mob ntawm qhov thib ob internode ntawm taum seedlings nrog 10 ng. L-1 ntawm brassinolide tuaj yeem ua rau lub internode kom elongate thiab khoov, ua kom lub cell faib, nthuav cov internode, thiab txawm tawg. Qhov kev loj hlob zoo teb no yog siv los ua bioassay rau brassinolide. BR txhawb nqa cell faib thiab elongation vim nws txhim khu kev ua haujlwm RNA polymerase thiab txhawb kev sib txuas ntawm nucleic acids thiab proteins; BR1 tuaj yeem txhim kho ATPase kev ua haujlwm, txhawb kev zais ntawm H + los ntawm cov ntshav plasma mus rau phab ntsa ntawm tes, thiab ua rau cov cell elongation.

BR tuaj yeem txhawb kev loj hlob ntawm tag nrho cov nroj tsuag. Tom qab kho qhov thib ob internode ntawm taum seedlings nrog brassinolide, lub internode tuaj yeem loj hlob tsis pub dhau ob peb hnub; tom qab ob peb lub lis piam, kev loj hlob ntawm tag nrho cov nroj tsuag tuaj yeem txhawb nqa, suav nrog qhov siab ntawm cov nroj tsuag, cog qhov hnyav, pods qhov hnyav, thiab tus naj npawb ntawm buds, uas yog qhov loj dua piv nrog cov pab pawg tswj.

(2) Txhawb nqa photosynthesis

BR tuaj yeem txhawb nqa kev ua haujlwm ntawm RuBP carboxylase hauv cov nplooj nplej thiab ua kom cov photosynthetic nce. BR, 9 hnub tom qab cov txiv laum huab xeeb tau kho, cov ntsiab lus chlorophyll yog 10% ~ 12% siab dua li kev tswj hwm, thiab tus nqi photosynthetic tau nrawm los ntawm 15%. Kev kuaj CO2 tracer pom tau tias kev kho BR1 txhawb nqa kev thauj khoom photosynthetic hauv nplooj mus rau panicle.

(3) Txhim kho kev ntxhov siab

Thaum cov noob qoob loo loj hlob nyob rau hauv qhov kub thiab txias, yog tias cov hauv paus hniav tau tsau rau hauv 10mg · LBR1 tov rau 24h, cov nroj tsuag qhov siab, nplooj nplooj, tus naj npawb ntawm tiller, thiab cov hauv paus qoob loo yog siab tshaj qhov kev tswj, thiab cov noob ciaj sia taus yog. siab thiab saum toj no qhuav hnyav nce ho. Tsis tas li ntawd, BR1 kuj tau txhim kho qhov kub tsis kam ntawm mov, eggplant, dib seedlings, thiab lwm yam.

Tsis tas li ntawd, BR kuj tseem tuaj yeem txhim kho kev tiv thaiv ntawm cov nroj tsuag kom qhuav, kab mob, ntsev puas, tshuaj tua kab, tshuaj tua kab puas tsuaj thiab lwm yam kev phem los ntawm nws cov nyhuv ntawm cov cell membranes. Yog li ntawd, qee cov neeg hu nws "kev txom nyem mitigation hormone."

(4) Lwm yam physiological teebmeem

Epibrassinolide muaj "cov hluas thiab ncua kev laus" cov nyhuv ntawm mung taum hypocotyl ntu thiab txhawb nqa qhov elongation ntawm dib hypocotyls. BR muaj txiaj ntsig zoo rau kev txhim kho cov haujlwm ntawm nitrate reductase (NR) hauv dib cotyledons.

24-EpiBrassinolide tuaj yeem tswj cov photosynthesis, ua pa, thiab transpiration ntawm cov nroj tsuag. Nws tuaj yeem txhawb kev ua haujlwm ntawm RuBP carboxylase hauv cov nplooj ntoo, nce chlorophyll cov ntsiab lus, thiab nce lub peev xwm ntawm C02, yog li ua kom cov photosynthetic thiab txo cov nyhuv inhibitory ntawm lub teeb ntawm kev loj hlob. Piv nrog rau photosynthesis, qhov ua tau zoo ntawm 24-EpiBrassinolide los txhawb kev ua pa qis dua, qhov kev ua haujlwm nrawm nrawm dua, thiab cov txiaj ntsig tau khaws cia ntev dua. Txau cov nplooj ntawm txiv apples thiab walnuts nrog ntuj 24-EpiBrassinolide tuaj yeem txo qhov kev siv ntawm nplooj.

Kev tsim nyog cov ntsiab lus ntawm 24-EpiBrassinolide tuaj yeem txhawb kev loj hlob ntawm cov ntaub so ntswg callus. Thaum cov concentration siab dhau lawm, cov ntaub so ntswg callus ua browner thiab inhibits kev loj hlob ntawm callus ntaub so ntswg. 24-EpiBrassinolide muaj cov nyhuv ua kom tshiab thiab tiv thaiv kev laus rau kev txiav calla lilies. Tsis tas li ntawd, 24-EpiBrassinolide kuj qhia tau hais tias muaj txiaj ntsig zoo hauv kev txhim kho cov nroj tsuag. Piv txwv li, 24-EpiBrassinolide tuaj yeem ua rau cov ntsiab lus ntawm cov dej txheeb ze thiab qhov tseem ceeb saturation tsis txaus ntawm nplooj ntawm txiv apples thiab walnuts, txo cov dej saturation deficit, dej yuav tsum tau, transpiration npaum li cas, cell membrane permeability thiab puas tus nqi, txo cov dej poob hauv nplooj, thiab txhim kho lawv cov drought resistance.
