I-asidi ye-Gibberellic 10%TA

Umphumela Wemvelo

Khuthaza ukunwebeka nokukhula kweziqu
Umphumela obaluleke kakhulu womzimba we-gibberellin acid (gibberellin) ukukhuthaza ukukhula kwezitshalo, ikakhulukazi ngoba ingakhuthaza ukwanda kwamaseli. Ukukhuthazwa kokukhula kwe-GA kunezici ezilandelayo:

1. Ukuze kukhuthazwe ukukhula kwezitshalo eziphelele, ukwelashwa kwe-GA kungakhuthaza kakhulu ukukhula kweziqu zezitshalo, ikakhulukazi ezinhlotsheni eziguquliwe ezincane, njengoba kuboniswe kuMfanekiso 7-11. Kodwa-ke, i-GA ayizange ibe nomthelela omkhulu ekunwetshweni kwezingxenye zesiqu ezihlukanisiwe, kuyilapho i-IAA ibe nomthelela omkhulu ekunwetshweni kwezingxenye zesiqu ezihlukanisiwe. Isizathu sokuthi i-GA ikhuthaza ukunwetshwa kwezitshalo ezihlukanisiwe ukuthi okuqukethwe yi-GA ezinhlotsheni ezihlukanisiwe kuphansi kunalokho ezinhlotsheni ezivamile ngenxa yokuvinjelwa kokwenziwa kwe-GA engokwemvelo.

2. Ukukhuthaza ukunwetshwa kwama-internode I-GA isebenza kakhulu ekunwetshweni kwama-internode okukhona, kunokuba ikhuthaze ukwanda kwenani lama-node.

3. Akukho mphumela wokuvinjelwa kokuhlushwa okuphezulu kakhulu Ngisho noma ukuhlushwa kwe-GA kuphezulu kakhulu, kusabonisa umphumela wokukhushulwa okuphezulu kakhulu, okuhluke kakhulu esimweni lapho i-auxin ikhuthaza ukukhula kwezitshalo ngokuhlushwa okuphezulu.

4. Ukusabela kwezinhlobo ezahlukene zezitshalo nezinhlobo ku-GA kuhluke kakhulu. Isivuno esikhulu singatholakala ngokusebenzisa i-GA emifinweni (isilimo esidliwayo esinamagatsha anamanzi, ilethisi, i-leek), utshani, itiye, i-ramie nezinye izitshalo.

Izimbali ezibangelwayo
Ukwehluka kwamahlumela ezimbali kwezinye izitshalo eziphakeme kuthonywa ubude bosuku (isikhathi sesithombe) kanye nokushisa. Isibonelo, izimbali zeminyaka emibili zidinga inani elithile lezinsuku zokwelashwa kwezinga lokushisa eliphansi (okungukuthi, ukuvuthwa kwezimbali) ukuze ziqhakaze, ngaphandle kwalokho zibonisa ukukhula kwe-rosette ngaphandle kokuqhakaza kwezimbali. Uma i-GA isetshenziswa kulezi zitshalo ezingavuthiwe, ukuqhakaza kungabangelwa ngaphandle kwenqubo yokushisa okuphansi, futhi umphumela usobala kakhulu. Ngaphezu kwalokho, i-GA ingaphinde ibangele ukuqhakaza kwezinye izitshalo ezihlala usuku olude esikhundleni sezitshalo ezihlala usuku olude, kodwa i-GA ayinawo umthelela wokukhuthaza ukuhlukaniswa kwamahlumela ezimbali ezitshalo ezihlala usuku olufushane. Isibonelo, i-GA ingakhuthaza ukuqhakaza kwezitshalo ze-stevia, isihlahla sensimbi kanye ne-cypress kanye ne-fir.

Ukungaphumuli kwekhefu
Ukwelapha amazambane angasebenzi nge-2 ~ 3μg·g GA kungenza akhule ngokushesha, ukuze kuhlangatshezwane nezidingo zokutshala amazambane izikhathi eziningana ngonyaka. Ukuze imbewu edinga ukukhanya nokushisa okuphansi ukuze ikhule, njenge-lettuce, ugwayi, i-Perilla, iplamu kanye nembewu yama-apula, i-GA ingathatha indawo yokukhanya nokushisa okuphansi ukuze iphule ukungadli, ngoba i-GA ingadala ukwenziwa kwe-α-amylase, i-protease kanye nezinye i-hydrolases, futhi ikhuthaze ukuwohloka kwezinto ezigcinwe embewini ukuze kukhule futhi kuthuthukiswe ama-embryo. Embonini yokukhiqiza ubhiya, ukwelapha imbewu yebhali ehlumayo ngaphandle kokuhluma nge-GA kungadala ukukhiqizwa kwe-α-amylase, kusheshiswe inqubo ye-saccharification ngesikhathi sokupheka, futhi kuncishiswe ukusetshenziswa kokuphefumula kokuhluma, ngaleyo ndlela kuncishiswe izindleko.

Khuthaza ukuhlukaniswa kwezimbali zesilisa
Isilinganiso sezimbali zesilisa sanda ngemva kokwelashwa kwe-GA kwezitshalo ezinesitshalo esifanayo. Izitshalo zesifazane ezine-dioecious, uma ziphathwa nge-GA, nazo zizokhiqiza izimbali zesilisa. Umphumela we-GA kulokhu uphambene nowe-auxin ne-ethylene.

Umphumela Wemvelo

I-GA ingaqinisa nomphumela wokuhlanganisa i-IAA kwizakhamzimba, ikhuthaze ukubekwa kwezithelo kanye ne-parthenocarpy yezitshalo ezithile, futhi ilibazise ukuguga kwamaqabunga. Ngaphezu kwalokho, i-GA ingakhuthaza nokuhlukaniswa kwamaseli, kanti i-GA ikhuthaza ukuhlukaniswa kwamaseli ngenxa yokufinyezwa kwezigaba ze-G1 kanye ne-S. Kodwa-ke, i-GA ivimbela ukwakheka kwezimpande ezifikayo, okuhlukile ku-auxin.

Indlela yokusebenzisa

1. Khuthaza ukwakheka kwezithelo noma izithelo ezingenambewu. Futha ukhukhamba ngoketshezi olungama-50-100mg/kg kanye ngesikhathi sokuqhakaza ukuze kukhuthazwe ukwakheka kwezithelo futhi kwandiswe isivuno. Ezinsukwini eziyi-7-10 ngemva kokuqhakaza, amagilebhisi anephunga elimnandi le-rose afuthwa ngoketshezi olungama-200-500mg/kg kanye ukuze kukhuthazwe ukwakheka kwezithelo ezingenamatshe.

2. Khuthaza ukukhula kokudla okunomsoco kwe-celery amasonto ama-2 ngaphambi kokuvuna, fafaza amaqabunga ngomuthi owuketshezi ongu-50-100mg/kg kanye; Fafaza amaqabunga izikhathi ezingu-1-2 amasonto ama-3 ngaphambi kokuvuna ukuze wandise iziqu namaqabunga.

3. Cwilisa izilimo eziyizigaxa ngesisombululo esingu-0.5-1mg/kg imizuzu engama-30 ngaphambi kokuhlwanyela amazambane ukuze kuqedwe ukubola nokukhuthaza ukuhluma; Ukucwilisa imbewu nge-1mg/kg yomuthi owuketshezi ngaphambi kokuhlwanyela kungakhuthaza ukuhluma.

4. Umphumela wokulwa nokuguga nokugcina okusha I-garlic moss enesixazululo semithi esingu-50mg/kg imizuzu eyi-10-30, isikhathi sezithelo eziluhlaza okotshani nesixazululo semithi esingu-5-15mg/kg fafaza izithelo kanye, ubhanana ngemva kokuvuna ngesisombululo semithi esingu-10mg/kg faka izithelo, ukhukhamba, ikhabe ngaphambi kokuvuna ngesisombululo semithi esingu-10-50mg/kg fafaza ikhabe, ingadlala umphumela wokugcina okusha.

5. Lungisa isigaba sokuvuthwa kwe-chrysanthemum eqhakazayo ngamaqabunga okufutha ngoketshezi angu-1000mg/kg, isigaba sokuhluma kwe-cyclamen ngamahlumela okufutha ngoketshezi angu-1-5mg/kg singakhuthaza ukuqhakaza.

6. Ukuze kuthuthukiswe izinga lokubeka imbewu ekukhiqizweni kwembewu yelayisi elixubile, ngokuvamile kuqalwa ngesihloko esingu-15% sikamama, bese kwelashwa ngomuthi owuketshezi ongu-25-55mg/kg izikhathi ezingu-1-3 ekupheleni kwesihloko esingu-25%. Sebenzisa ukugxila okuphansi kuqala, bese kuba ukugxila okuphezulu.

Izindaba ezidinga ukunakwa

1. I-asidi ye-gibberellic ayincibiliki emanzini kakhulu, ncibilika ngenani elincane lotshwala noma utshwala ngaphambi kokusebenzisa, bese uyincibilikisa ngamanzi kuze kufike ezingeni elidingekayo.

2. Imbewu engcolile yezitshalo eziphathwe nge-gibberellic acid yanda, ngakho-ke akufaneleki ukufaka umuthi emasimini okutshala.
