I-asidi yeGibberellic 10%TA

Impembelelo yePhysical

Khuthaza ukwandiswa nokukhula kweziqu
Eyona mpembelelo ibalulekileyo kwi-physiological ye-gibberellinic acid (gibberellin) kukukhuthaza ukukhula kwezityalo, kuba ikakhulu inokukhuthaza ukwanda kweeseli. Ukukhuthazwa kokukhula kwe-GA kuneempawu ezilandelayo:

1. Ukukhuthaza ukukhula kwezityalo ezipheleleyo, unyango lwe-GA lunokukhuthaza kakhulu ukukhula kweziqu zezityalo, ngakumbi kwiintlobo ze-dwarf mutant, njengoko kubonisiwe kuMfanekiso 7-11. Nangona kunjalo, i-GA ayizange ibe nefuthe elikhulu ekwandiseni iziqwenga zesiqu ezizimeleyo, ngelixa i-IAA yayinefuthe elikhulu ekwandiseni iziqwenga zesiqu ezizimeleyo. Isizathu sokuba i-GA ikhuthaze ukwanda kwezityalo ezi-dwarf kukuba umxholo we-GA kwiintlobo ze-dwarf uphantsi kunowohlobo oluqhelekileyo ngenxa yokuphazamiseka kokwenziwa kwe-GA endalo.

2. Ukukhuthaza ukunwebeka kwama-internode I-GA isebenza ikakhulu ekunwebekeni kwama-internode akhoyo, endaweni yokukhuthaza ukwanda kwenani lama-node.

3. Akukho siphumo sokuthintela uxinaniso oluphezulu kakhulu Nokuba uxinaniso lwe-GA luphezulu kakhulu, lusenokubonisa isiphumo sokukhuthaza esiphezulu, esahluke kakhulu kwimeko apho i-auxin ikhuthaza ukukhula kwezityalo ngoxinaniso olufanelekileyo.

4. Indlela iintlobo ezahlukeneyo zezityalo kunye neentlobo ezahlukeneyo ezisabela ngayo kwi-GA yahlukile kakhulu. Isivuno esiphezulu sinokufunyanwa ngokusebenzisa i-GA kwimifuno (iseleri, ilettuce, iliki), ingca, iti, iramie kunye nezinye izityalo.

Iintyatyambo ezibangelwayo
Ukwahluka kweentyatyambo kwezinye izityalo eziphakamileyo kuphenjelelwa bubude bemini (ixesha lefoto) kunye nobushushu. Umzekelo, izityalo ezineminyaka emibini zifuna inani elithile leentsuku zonyango oluphantsi lobushushu (oko kukuthi, ukuvuthwa kwentyatyambo) ukuze zidubule, kungenjalo zibonisa ukukhula kwerosette ngaphandle kokudubula kwentyatyambo. Ukuba i-GA isetyenziswa kwezi zityalo zingavuthwanga, ukudubula kunokubangelwa ngaphandle kwenkqubo yobushushu obuphantsi, kwaye isiphumo sicacile kakhulu. Ukongeza, i-GA inokubangela ukudubula kwezinye izityalo ezihlala ixesha elide endaweni yezityalo ezihlala ixesha elide, kodwa i-GA ayinayo impembelelo yokukhuthaza ukudubula kwezityalo ezihlala ixesha elifutshane. Umzekelo, i-GA inokukhuthaza ukudubula kwe-stevia, umthi wesinyithi kunye nezityalo ze-cypress kunye ne-fir.

Ukungaphumli kwekhefu
Ukunyanga iitapile ezingasebenziyo nge-2 ~ 3μg·g GA kungenza zikhule ngokukhawuleza, ukuze kuhlangatyezwane neemfuno zokutyala iitapile izihlandlo ezininzi ngonyaka. Kwimbewu ezifuna ukukhanya nobushushu obuphantsi ukuze zikhule, ezifana nelettuce, icuba, iPerilla, iplamu kunye nembewu yeapile, i-GA ingathatha indawo yobushushu obuphantsi kunye nobushushu obuphantsi ukuze iphule ukungahlali kakuhle, kuba i-GA inokubangela ukwenziwa kwe-α-amylase, iprotease kunye nezinye ii-hydrolases, kwaye ikhuthaze ukuwohloka kwezinto ezigciniweyo kwimbewu ukuze kukhule kwaye kuphuhliswe iimbumba. Kwishishini lokuvelisa ibhiya, ukunyanga imbewu yerhasi ekhulayo ngaphandle kokuhluma nge-GA kunokubangela ukuveliswa kwe-α-amylase, kukhawulezise inkqubo ye-saccharification ngexesha lokwenziwa kwebhiya, kwaye kunciphise ukusetyenziswa kokuphefumla kokuhluma, ngaloo ndlela kunciphisa iindleko.

Khuthaza ukwahluka kweentyatyambo zesilisa
Umlinganiselo weentyatyambo zesilisa wanda emva konyango lwe-GA kwizityalo ezinesityalo esifanayo. Izityalo zesilisa ezine-dioecious, ukuba zinyangwa nge-GA, nazo ziya kuvelisa iintyatyambo zesilisa. Isiphumo se-GA kule nkalo sichasene neso se-auxin kunye ne-ethylene.

Impembelelo yePhysical

I-GA inokomeleza isiphumo sokudityaniswa kwe-IAA kwizondlo, ikhuthaze ukubekwa kweziqhamo kunye ne-parthenocarpy kwezinye izityalo, kwaye ilibazise ukuguga kwamagqabi. Ukongeza, i-GA inokukhuthaza ukwahlulwahlulwa kweeseli kunye nokwahlukana kwazo, kwaye i-GA ikhuthaza ukwahlulwahlulwa kweeseli ngenxa yokufinyezwa kwezigaba ze-G1 kunye ne-S. Nangona kunjalo, i-GA ithintela ukwakheka kweengcambu ezingaphandle, ezahlukileyo kwi-auxin.

Indlela yokusebenzisa

1. Khuthaza ukwakheka kwesiqhamo okanye isiqhamo esingenambewu. Futha ikhukhamba nge-50-100mg/kg yolwelo kanye ngexesha lokudubula ukuze kukhuthazwe ukwakheka kwesiqhamo kwaye kwandiswe isivuno. Emva kweentsuku ezi-7-10 emva kokudubula, iidiliya ezinevumba elimnandi zerozi zatshizwa nge-200-500mg/kg yolwelo kanye ukuze kukhuthazwe ukwakheka kwesiqhamo esingenamatye.

2. Khuthaza ukukhula kwesondlo seseleri kwiiveki ezi-2 ngaphambi kokuvuna, faka amayeza angamanzi angama-50-100mg/kg kanye; Futha amagqabi izihlandlo ezi-1-2 kwiiveki ezi-3 ngaphambi kokuvuna ukuze wandise isiqu kunye namagqabi.

3. Nciphisa iityhubhu ngesisombululo se-0.5-1mg/kg imizuzu engama-30 ngaphambi kokuhlwayela iitapile ukuze ziphumle kwaye zikhuthaze ukuhluma; Ukumanzisa imbewu nge-1mg/kg yonyango oluyilwelo ngaphambi kokuhlwayela kunokubangela ukuhluma.

4. Isiphumo sokulwa nokwaluphala kunye nokugcina imifuno itsha I-garlic moss enesisombululo samayeza se-50mg/kg imizuzu eli-10-30, ixesha lesiqhamo esiluhlaza se-citrus kunye nesisombululo samayeza se-5-15mg/kg sitshiza iziqhamo kube kanye, ibhanana emva kokuvuna ngesisombululo samayeza se-10mg/kg sitshiza iziqhamo, ikhukhamba, ivatala ngaphambi kokuvuna ngesisombululo samayeza se-10-50mg/kg sitshiza ivatala, sinokudlala isiphumo sokugcina imifuno itsha.

5. Lungisa inqanaba lokukhula kwe-chrysanthemum eqhakazayo ngamagqabi okutshiza angamanzi ayi-1000mg/kg, inqanaba lokuhluma kwe-cyclamen ngamahlumela okutshiza angamanzi ayi-1-5mg/kg linokukhuthaza ukuhluma.

6. Ukuphucula izinga lokubekwa kwembewu kwimveliso yembewu yerayisi exutyiweyo, ngokuqhelekileyo iqalwa kwi-15% yentloko yomama, kwaye inyangwe nge-25-55mg/kg yeyeza lolwelo izihlandlo ezi-1-3 ekupheleni kwentloko ye-25%. Sebenzisa uxinano oluphantsi kuqala, uze emva koko uxinano oluphezulu.

Imiba efuna ingqwalasela

1. I-asidi ye-gibberellic ayinyibiliki emanzini kakhulu, yinyibilikise ngomlinganiselo omncinci wotywala okanye utywala ngaphambi kokuba uyisebenzise, ​​uze uyinyibilikise ngamanzi ukuya kumlinganiselo ofunekayo.

2. Imbewu engeyiyo eyomileyo yezityalo ezinyangiweyo nge-gibberellic acid inyukile, ngoko ke akufanelekanga ukusebenzisa amayeza emasimini okutyala.
