Gibberellic acid 10% TA

Physiological Effect

Limbikitsani kutalika ndi kukula kwa tsinde
Chofunikira kwambiri pazathupi la gibberellinic acid (gibberellin) ndikulimbikitsa kukula kwa mbewu, makamaka chifukwa zimatha kulimbikitsa kukula kwa maselo. Kukwezeleza kwa kukula kwa GA kuli ndi izi:

1. Pofuna kulimbikitsa kukula kwa zomera zonse, chithandizo cha GA chikhoza kulimbikitsa kwambiri kukula kwa tsinde la zomera, makamaka kwa mitundu yochepa ya mutant, monga momwe tawonetsera pa Chithunzi 7-11. Komabe, GA sinakhudze kwambiri kutalika kwa zigawo zakutali, pomwe IAA idakhudza kwambiri kufalikira kwa zigawo zakutali. Chifukwa chomwe GA imalimbikitsa kukula kwa zomera zazing'ono ndikuti zomwe zili mu GA mu mitundu yochepa kwambiri ndizochepa kusiyana ndi zamoyo zomwe zimakhala bwino chifukwa cha kutsekeka kwa GA synthesis.

2. Kulimbikitsa internode elongation GA makamaka amachita pa internode elongation alipo kale, m'malo kulimbikitsa kuwonjezeka chiwerengero cha mfundo.

3. Palibe choletsa zotsatira za superoptimal ndende Ngakhale ndende ya GA ndi yokwera kwambiri, imatha kuwonetsa mphamvu yolimbikitsira kwambiri, yomwe imakhala yosiyana kwambiri ndi momwe auxin imathandizira kukula kwa mbewu ndi ndende yabwino kwambiri.

4. Yankho la mitundu yosiyanasiyana ya zomera ndi mitundu ku GA ndi yosiyana kwambiri. Zokolola zambiri zitha kupezeka pogwiritsa ntchito GA pamasamba (celery, letesi, leek), udzu, tiyi, ramie ndi mbewu zina.

Kupanga maluwa
Kusiyanitsa kwa maluwa muzomera zina zapamwamba kumatengera kutalika kwa tsiku (photoperiod) ndi kutentha. Mwachitsanzo, biennials amafuna masiku angapo otsika kutentha mankhwala (ie, vernalization) kuti maluwa, apo ayi kusonyeza rosette kukula popanda bolting maluwa. Ngati GA ikugwiritsidwa ntchito ku zomera zosawerengekazi, maluwa amatha kupangika popanda kutentha kochepa, ndipo zotsatira zake ndi zoonekeratu. Kuphatikiza apo, GA imathanso kupangitsa kumera kwamaluwa amasiku atali m'malo mwazomera zamasiku ambiri, koma GA ilibe kulimbikitsa kusiyanitsa kwamaluwa amasiku ochepa. Mwachitsanzo, GA ikhoza kulimbikitsa maluwa a stevia, mtengo wachitsulo ndi cypress ndi fir zomera.

Kupuma kugona
Kuchiza mbatata zosalala ndi 2 ~ 3μg·g GA kutha kuzipangitsa kuti zimere mwachangu, kuti zikwaniritse zosowa zobzala mbatata kangapo pachaka. Mbeu zomwe zimafuna kuwala ndi kutentha kochepa kuti zimere, monga letesi, fodya, Perilla, maula ndi mbewu za apulo, GA imatha kusintha kuwala ndi kutentha pang'ono kuti iwononge dormancy, chifukwa GA ikhoza kuyambitsa kaphatikizidwe ka α-amylase, protease ndi ma hydrolases ena, ndikuthandizira kuwonongeka kwa zinthu zosungidwa mumbewu kuti zikule ndi kukula kwa mluza. M'makampani opanga moŵa, kuchiza mbewu za balere osamera popanda kumera ndi GA kungapangitse kupanga α-amylase, kufulumizitsa njira ya saccharification panthawi yopangira moŵa, komanso kuchepetsa kumera kwa kupuma, motero kuchepetsa ndalama.

Limbikitsani kusiyana kwa maluwa achimuna
Chiwerengero cha maluwa achimuna chinawonjezeka pambuyo pa chithandizo cha GA kwa zomera zomwe zili ndi zomera zomwezo. Zomera zachikazi za dioecious, ngati zimathandizidwa ndi GA, zidzatulutsanso maluwa achimuna. Zotsatira za GA pankhaniyi ndizosiyana ndi za auxin ndi ethylene.

Physiological Effect

GA imathanso kulimbikitsa kulimbikitsa kwa IAA pazakudya, kulimbikitsa kukhazikika kwa zipatso ndi parthenocarpy ya zomera zina, ndikuchedwetsa kumera kwa masamba. Kuphatikiza apo, GA imathanso kulimbikitsa kugawanika kwa maselo ndi kusiyanitsa, ndipo GA imalimbikitsa kugawanika kwa maselo chifukwa cha kufupikitsa magawo a G1 ndi S. Komabe, GA imalepheretsa mapangidwe adventitial mizu, yomwe ndi yosiyana ndi auxin.

Njira yogwiritsira ntchito

1. Limbikitsani kupanga zipatso kapena zipatso zopanda mbewu. Uza nkhaka ndi madzi a 50-100mg/kg kamodzi pa nthawi ya maluwa pofuna kulimbikitsa kukhazikika kwa zipatso ndi kuonjezera zokolola. Pakatha masiku 7-10 mutatha maluwa, mphesa zonunkhira za duwa zidathiridwa ndi 200-500mg/kg yamadzimadzi kamodzi kuti zilimbikitse kupanga zipatso zopanda miyala.

2. Limbikitsani kukula kopatsa thanzi kwa udzu winawake kutatsala milungu iwiri kukolola, tsitsani masamba ndi mankhwala amadzimadzi a 50-100mg/kg kamodzi; Uza masamba 1-2 katatu masabata atatu kukolola kukulitsa tsinde ndi masamba.

3. Zilowerereni ma tubers ndi njira ya 0.5-1mg/kg kwa mphindi 30 musanabzale mbatata kuti iwononge dormancy ndikulimbikitsa kumera; Kuviika mbeu ndi 1mg/kg ya mankhwala amadzimadzi musanabzale kungathandize kumera.

4. Anti-kukalamba ndi kusunga mwatsopano zotsatira Garlic moss ndi 50mg/kg mankhwala njira 10-30min, citrus wobiriwira zipatso nyengo ndi 5-15mg/kg mankhwala mankhwala utsi zipatso kamodzi, nthochi pambuyo kukolola ndi 10mg/kg mankhwala zilowerere zipatso, nkhaka, chivwende chivwende-50 mg wa mankhwala opopera/50 mg/50 mg/10 mg wa mankhwala. mwatsopano-kusunga zotsatira.

5. Sinthani maluwa chrysanthemum vernalization siteji ndi 1000mg/kg madzi kutsitsi masamba, cyclamen Mphukira siteji ndi 1-5mg/kg madzi kutsitsi masamba akhoza kulimbikitsa maluwa.

6. Pofuna kukonza mbeu za kalimidwe ka mpunga wosakanizidwa, imayamba pa 15% ya mutu wa mayi, ndikuthira mankhwala amadzimadzi a 25-55mg/kg ka 1-3 pa mapeto a 25%. Gwiritsani ntchito ndende yotsika poyamba, ndiyeno kukwera kwakukulu.

Zinthu zofunika kuziganizira

1. Gibberellic acid ndi yocheperapo sungunuka m'madzi, amasungunuka ndi mowa pang'ono kapena zakumwa zoledzeretsa musanagwiritse ntchito, ndiyeno amasungunula ndi madzi kumagulu ofunikira.

2. Mbeu zosabala za mbewu zomwe zimagwiritsidwa ntchito ndi gibberellic acid zidawonjezeka, kotero sikoyenera kugwiritsa ntchito mankhwala m'minda yobzala.
