I-Gibberellic acid 10% TA

Physiological Effect

Khuthaza ukunwebeka nokukhula kweziqu
Umphumela obaluleke kakhulu we-physiological we-gibberellinic acid (gibberellin) ukukhuthaza ukukhula kwesitshalo, ikakhulukazi ngoba ungakhuthaza ukunwetshwa kwamaseli. Ukukhuthazwa kokukhula kwe-GA kunezici ezilandelayo:

1. Ukuze kuthuthukiswe ukukhula kwezitshalo eziphelele, ukwelashwa kwe-GA kungakhuthaza kakhulu ukukhula kweziqu zezitshalo, ikakhulukazi ezinhlobonhlobo eziguquguqukayo ezincane, njengoba kuboniswe kuMfanekiso 7-11. Kodwa-ke, i-GA ayizange ibe nomthelela omkhulu ekwandiseni izingxenye ze-stem ezihlukanisiwe, kuyilapho i-IAA ibe nomthelela omkhulu ekwandiseni amasegimenti esiqu angawodwa. Isizathu esenza i-GA ikhuthaze ukunwetshwa kwezitshalo ezincane ukuthi okuqukethwe kwe-GA ezinhlobonhlobo ezincane kungaphansi kwalokho kwezinhlobo ezivamile ngenxa yokuvinjwa kokuhlanganiswa kwe-GA yemvelo.

2. Ukuthuthukisa i-internode elongation GA ikakhulukazi isebenza ekweluleni okukhona kwama-internode, kunokugqugquzela ukwanda kwenani lamanodi.

3. Awukho umphumela wokuvinjelwa wokugxila okuphezulu Ngisho noma ukuhlushwa kwe-GA kuphezulu kakhulu, kusengabonisa umphumela omkhulu wokugqugquzela, ohluke kakhulu esimweni lapho i-auxin ikhuthaza ukukhula kwezitshalo ngokugxila okuphezulu.

4. Ukusabela kwezinhlobo ezahlukene zezitshalo nezinhlobonhlobo ku-GA kuhluke kakhulu. Isivuno esiphezulu singatholakala ngokusebenzisa i-GA emifino (isilimo esidliwayo esinamagatsha anamanzi, ulethisi, i-leek), utshani, itiye, i-ramie nezinye izitshalo.

Ukuqhakaza kwezimbali
Ukuhlukaniswa kwezimbali kwezinye izitshalo eziphakeme kuthonywa ubude bosuku (photoperiod) kanye nezinga lokushisa. Isibonelo, ama-biennials adinga inani elithile lezinsuku zokwelashwa kwezinga lokushisa eliphansi (okungukuthi, ukuguqulwa kwe-vernalization) ukuze kuqhakaze, ngaphandle kwalokho abonisa ukukhula kwe-rosette ngaphandle kokuqhakaza kwezimbali. Uma i-GA isetshenziswa kulezi zitshalo ezingavunyelwe, ukuqhakaza kungenziwa ngaphandle kwenqubo yokushisa ephansi, futhi umphumela usobala kakhulu. Ngaphezu kwalokho, i-GA ingase futhi ibangele ukuqhakaza kwezitshalo zezinsuku ezinde esikhundleni sezitshalo zosuku olude, kodwa i-GA ayinawo umthelela okhuthaza ukuhlukaniswa kwezimbali zezitshalo zezinsuku ezifushane. Isibonelo, i-GA ingakhuthaza ukuqhakaza kwe-stevia, isihlahla sensimbi kanye ne-cypress kanye nezitshalo ze-fir.

Phula i-dormancy
Ukwelapha amazambane alele nge-2 ~ 3μg·g GA kungawenza ahlume ngokushesha, ukuze ahlangabezane nezidingo zokutshala amazambane izikhathi eziningana ngonyaka. Ukuze imbewu edinga izinga lokushisa elikhanyayo neliphansi ukuze imile, njengembewu ye-ulethisi, ugwayi, i-Perilla, iplamu ne-apula, i-GA ingathatha indawo yokukhanya nezinga lokushisa eliphansi ukuze iphule i-dormancy, ngoba i-GA ingabangela ukuhlanganiswa kwe-α-amylase, i-protease namanye ama-hydrolase, futhi ibangele ukuwohloka kwezinto ezigcinwe embewini ukuze kukhule futhi kuthuthukiswe umbungu. Embonini yokukhiqiza ubhiya, ukwelapha imbewu yebhali ehlumayo ngaphandle kokuhluma nge-GA kungabangela ukukhiqizwa kwe-α-amylase, kusheshise inqubo ye-saccharification ngesikhathi sokuphuza, futhi kunciphise ukusetshenziswa kokuphefumula kokuhluma, ngaleyo ndlela kunciphise izindleko.

Thuthukisa ukuhlukaniswa kwezimbali zabesilisa
Ingxenye yezimbali zesilisa yanda ngemva kokwelashwa kwe-GA kwezitshalo ezinesitshalo esifanayo. Izitshalo ze-dioecious zesifazane, uma ziphathwa nge-GA, zizokhiqiza izimbali zesilisa. Umphumela we-GA kulokhu uphambene nalokho we-auxin ne-ethylene.

Physiological Effect

I-GA ingaphinda iqinise umphumela wokuhlanganisa we-IAA kumsoco, ikhuthaze ukumiswa kwezithelo kanye ne-parthenocarpy yezinye izitshalo, futhi ibambezele ukukhula kwamaqabunga. Ngaphezu kwalokho, i-GA ingaphinde ikhuthaze ukuhlukaniswa kwamaseli nokuhlukaniswa, futhi i-GA ikhuthaza ukuhlukana kwamaseli ngenxa yokufinyezwa kwezigaba ze-G1 ne-S. Kodwa-ke, i-GA ivimbela ukwakheka kwezimpande ze-adventitial, ehlukile ku-auxin.

Indlela yokusebenzisa

1. Khuthaza ukwakheka kwesithelo noma isithelo esingenambewu. Fafaza ukhukhamba ngoketshezi oluyi-50-100mg/kg kanye ngesikhathi sokuqhakaza ukuze ukhuthaze ukuhlelwa kwezithelo nokwandisa isivuno. Ezinsukwini ezingu-7-10 ngemva kokuqhakaza, amagilebhisi anephunga elimnandi afafazwa ngo-200-500mg/kg woketshezi kanye ukuze kuthuthukiswe ukwakheka kwesithelo esingenamatshe.

2. Khuthaza ukukhula okunomsoco kwesilimo esidliwayo esinamagatsha anamanzi emasontweni amabili ngaphambi kokuvuna, fafaza amaqabunga ngomuthi owuketshezi ongu-50-100mg/kg kanye; Fafaza amaqabunga izikhathi ezi-1-2 amasonto amathathu ngaphambi kokuvuna ukuze ukhulise iziqu namaqabunga.

3. Cwilisa izilimo eziyizigaxa ngesixazululo esingu-0.5-1mg/kg imizuzu engama-30 ngaphambi kokuhlwanyela amazambane ukuze aphule umoya futhi akhuthaze ukuhluma; Ukucwilisa imbewu ngo-1mg/kg womuthi owuketshezi ngaphambi kokuhlwanyela kungakhuthaza ukuhluma.

4. Umphumela wokunqanda ukuguga nokugcina ubusha Ubulembu obuno-50mg/kg obunomuthi obungama-50mg/kg imizuzu eyi-10-30, isikhathi sezithelo ezisawolintshi ezino-5-15mg/kg ngesixazululo somuthi fafaza izithelo kanye, ubhanana ngemva kokuvuna ngo-10mg/kg isixazululo somuthi cwilisa isithelo, ikhukhamba, ikhabe ngaphambi kokuvuna, dlala ikhabe-50mg ngekhambi lekhambi/50mg. umphumela wokugcina omusha.

5. Lungisa isigaba sokuqhakaza se-chrysanthemum vernalization namaqabunga e-1000mg/kg we-liquid spray, isigaba se-cyclamen bud esine-1-5mg/kg liquid spray buds singakhuthaza ukuqhakaza.

6. Ukwenza ngcono izinga lokumiswa kwembewu yokukhiqizwa kwembewu yerayisi eyingxube, ngokuvamile iqalwa ku-15% wesihloko sikamama, bese iphathwa ngomuthi owuketshezi ongu-25-55mg/kg izikhathi ezingu-1-3 ekupheleni kwesihloko esingu-25%. Sebenzisa ukugxila okuphansi kuqala, bese ugxila kakhulu.

Izindaba ezidinga ukunakwa

1. I-Gibberellic acid ayincibiliki emanzini, incibilika ngenani elincane lotshwala noma utshwala ngaphambi kokusetshenziswa, bese ihlanjululwa ngamanzi ekugxiliseni okudingekayo.

2. Imbewu eyinyumba yezitshalo eziphathwe nge-gibberellic acid yanda, ngakho-ke akufanelekile ukusebenzisa umuthi emasimini okutshala.
