Taw qhia
Cov khoom no yog cov khoom siv roj ntsha fermentation, thiab nws cov khoom xyaw nquag yog gibberellic acid. Gibberellic acid tau tshawb pom thaum lub sijhawm tshawb fawb txog kab mob qoob loo, nws yog ib lub ntsiab lus dav dav rau cov chav kawm ntawm cov tebchaw uas muaj cov pob txha gibberellin thiab tuaj yeem txhawb nqa cell faib thiab elongation. lt belongs rau cog kev loj hlob regulators thiab yog ib qho ntawm ntshuam-anthormones uas txhawb cov nroj tsuag kev loj hlob thiab kev loj hlob.
Kev ua haujlwm ntawm Gibberellik Acid
Txhawb nqa elongation:Qhov tseem ceeb tshaj plaws physiological nyhuv ntawm gibberellic acid yog los txhawb kev loj hlob ntawm cov nroj tsuag, feem ntau yog los ntawm kev txhawb cell elongation thiab txhawb kev loj hlob ntawm tag nrho cov nroj tsuag. Kev kho mob nrog gibberellic acid tuaj yeem txhawb kev loj hlob ntawm cov nroj tsuag stems, tshwj xeeb tshaj yog cov txiaj ntsig ntawm dwarf mutant ntau yam yog qhov tshwj xeeb.
Tshem tawm dormancy:Kev kho cov qos yaj ywm dormant nrog 2 ~ 3ug.g ntawm gibberellic acid tuaj yeem ua rau lawv sprouts sai, yog li ua tau raws li qhov xav tau rau cog qos yaj ywm ntau zaus hauv ib xyoos. Rau cov noob uas xav tau lub teeb thiab tsis kub kom tawg, xws li lettuce, tobac.co, perilla, plum thiab txiv apples, gibberellic acid tuaj yeem hloov lub teeb thiab kub kub kom tawg dormancy. Qhov no yog vim hais tias gibberellic acid tuaj yeem ua rau muaj kev sib txuas ntawm -amylase, protease thiab lwm yam hydrolytic enzymes, catalyze degradation ntawm cov khoom khaws cia hauv cov noob, muab kev loj hlob thiab kev loj hlob ntawm embryo.
Induce paj:Qhov sib txawv ntawm paj buds nyob rau hauv qee cov nroj tsuag siab dua yog cuam tshuam los ntawm hnub ntev (piv txwv li, photoperiod) thiab kub. Piv txwv li, rau cov nroj tsuag biennial muaj pes tsawg hnub ntawm qis - kev kho kub (ie, vernalization) yog xav tau kom paj, txwv tsis pub lawv qhia rosette kev loj hlob thiab tsis tuaj yeem bolt rau paj. Yog hais tias gibberellic acid yog siv rau cov uas tsis yog -vernalized nroj tsuag, flowering yuav induced yam tsis muaj qhov qis - txheej txheem kub, thiab cov nyhuv yog pom tseeb heev. Tsis tas li ntawd, nws tseem tuaj yeem hloov lub hnub ntev los ua kom muaj paj paj hauv qee cov nroj tsuag ntev -hnub, tab sis gibberellic acid tsis muaj kev txhawb nqa rau kev sib txawv ntawm paj buds nyob rau hauv luv luv -hnub nroj tsuag. Rau cov nroj tsuag nrog cov paj sib txawv, gibberellic acid muaj qhov cuam tshuam loj rau kev qhib lawv cov paj. Piv txwv li, gibberellic acid tuaj yeem txhawb kev paj ntawm stevia, tsob ntoo lron, thiab cov nroj tsuag ntawm Cupressaceae thiab Pinaceae tsev neeg.
Txhawb kev sib txawv ntawm txiv neej paj:Rau cov nroj tsuag monoecious, tom qab kev kho mob nrog gibberellic acid, qhov kev faib ua feem ntawm txiv neej paj nce; rau cov nroj tsuag dioecious, yog hais tias tus poj niam nroj tsuag tau kho nrog gibberellic acid, txiv neej paj kuj Bloom.
Lwm yam teebmeem physiological:Gibberellic acid kuj tseem tuaj yeem txhim kho cov nyhuv ntawm auxin ntawm cov as-ham, txhawb qee cov nroj tsuag kom tsim cov txiv hmab txiv ntoo thiab cov txiv hmab txiv ntoo unisexual, ncua cov nplooj senescence, thiab lwm yam, ntxiv rau, gibberellic acid kuj tseem tuaj yeem txhawb kev faib tawm ntawm tes thiab kev sib txawv.
Scope ntawm kev siv
Cov khoom no yog cov khoom siv raw rau kev ua cov tshuaj tua kab, thiab tsis pub siv rau cov qoob loo lossis lwm qhov chaw. Cov ntaub ntawv ntau: 3% gibberellic acid EC40% gibberellic acid SG, 20% WT, 75% crystal hmoov, 85% crystal hmoov, thiab lwm yam.
Cim npe nrov: Tuam Tshoj gibberellic acid rau cov nroj tsuag manufacturers, lwm tus neeg, Hoobkas
