I-Dwarf Schefflera sisityalo sasekhaya esithandwayo kwihlabathi liphela, kwaye ukukhula kunye nophuhliso lwaso lufumana ingqalelo enkulu kule mihla.Ukusetyenziswa kwezilawuli zokukhula kwezityalo kubangele iyantlukwano ebalulekileyo, kunye nalo lonke unyango lokunyusa ukuphakama kwesityalo xa kuthelekiswa nolawulo.Nangona ubude besityalo buqhele ukulawulwa ngokwemfuza, uphando lubonisa ukuba ukusetyenziswa kwezilawuli zokukhula kwezityalo kunokunyusa okanye kunciphise ubude bezityalo.Ukuphakama kwesityalo kunye nenani lamagqabi aphathwe nge-gibberellic acid + benzyladenine 200 mg / L yayiphezulu, ifikelela kwi-109 cm kunye ne-38.25, ngokulandelanayo.Ngokuhambelana nezifundo zangaphambili (i-SalehiSardoei et al.52) kunye ne-Spathiphyllum23, ukunyuka okufanayo kokuphakama kwesityalo ngenxa yonyango lwe-gibberellic acid kwabonwa kwi-potted marigolds, i-albus alba21, i-daylilies22, i-daylilies, i-agarwood kunye neenyibiba zoxolo.
I-Gibberellic acid (GA) idlala indima ebalulekileyo kwiinkqubo ezahlukeneyo ze-physiological zezityalo.Zivuselela ukwahlukana kweeseli, ukwandiswa kweeseli, ukwanda kwesiqu kunye nokwanda kobungakanani24.I-GA yenza ulwahlulo lweeseli kunye nokwandiswa kwi-apices yehlumelo kunye ne-meristems25.Utshintsho lwamagqabi lukwabandakanya ukuncipha kobungqingqwa besikhondo, ubungakanani bamagqabi amancinci, kunye nombala oluhlaza oqaqambileyo26.Izifundo ezisebenzisa i-inhibitory okanye izinto ezikhuthazayo zibonise ukuba i-calcium ions evela kwimithombo yangaphakathi isebenza njengezithunywa zesibini kwi-gibberellin yokubonisa indlela ye-sorghum corolla27.I-HA yandisa ubude bezityalo ngokuvuselela ukuhlanganiswa kwee-enzyme ezibangela ukuphumla kodonga lweseli, njenge-XET okanye i-XTH, i-expansins kunye ne-PME28.Oku kubangela ukuba iiseli zande njengoko udonga lweseli luphumla kwaye amanzi engena kwiseli29.Ukusetyenziswa kwe-GA7, GA3 kunye ne-GA4 kunokunyusa ubude besiqu30,31.I-asidi ye-Gibberellic ibangela ukwanda kwesiqu kwizityalo ezincinci, kwaye kwizityalo zerosette, i-GA ibambezela ukukhula kwamagqabi kunye nobude be-internode32.Nangona kunjalo, ngaphambi kwesigaba sokuzala, ubude besiqu buyanda ukuya kumaxesha ama-4-5 ubude bawo bokuqala33.Inkqubo ye-GA biosynthesis kwizityalo ishwankathelwa kuMfanekiso 9.
I-GA biosynthesis kwizityalo kunye namanqanaba e-endogenous bioactive GA, ukumelwa kwenkqubo yezityalo (ekunene) kunye ne-GA biosynthesis (ekhohlo).Iintolo zinombala wekhowudi ukuhambelana nemo ye-HA eboniswe ecaleni kwendlela ye-biosynthetic;iintolo ezibomvu zibonisa amanqanaba e-GC anciphileyo ngenxa yendawo yokuhlala kwizitho zezityalo, kunye neentolo ezimnyama zibonisa amanqanaba eGC anyukileyo.Kwizityalo ezininzi, ezifana nerayisi kunye ne-watermelon, umxholo we-GA uphezulu kwisiseko okanye inxalenye ephantsi yeqabunga30.Ngaphezu koko, ezinye iingxelo zibonisa ukuba umxholo we-GA we-bioactive wehla njengoko amagqabi ekhula ukusuka kwisiseko34.Amanqanaba achanekileyo e-gibberellins kula matyala awaziwa.
Izilawuli zokukhula kwezityalo zikwachaphazela kakhulu inani kunye nommandla wamagqabi.Iziphumo zibonise ukuba ukwandisa ukugxininiswa kokulawula ukukhula kwezityalo kubangele ukwanda okukhulu kwendawo yamagqabi kunye nenani.I-Benzyladenine iye yabikwa ukuba yonyusa imveliso yamagqabi e-calla15.Ngokweziphumo zolu phononongo, lonke unyango luphucule indawo yamagqabi kunye nenani.I-Gibberellic acid + benzyladenine yayiyeyona yonyango isebenzayo kwaye ibangele inani elikhulu kunye nendawo yamagqabi.Xa ukhulisa i-schefflera encinci ngaphakathi endlwini, kunokubakho ukwanda okubonakalayo kwinani lamagqabi.
Unyango lwe-GA3 lonyuse ubude be-internode xa kuthelekiswa ne-benzyladenine (BA) okanye akukho nyango lwe-hormonal.Esi siphumo siyavakala xa kujongwa indima ye-GA ekukhuthazeni ukukhula7.Ukukhula kwesiqu nako kubonise iziphumo ezifanayo.I-asidi ye-Gibberellic yandisa ubude besiqu kodwa yanciphisa ububanzi bayo.Nangona kunjalo, ukusetyenziswa okudityanisiweyo kwe-BA kunye ne-GA3 kwandise kakhulu ubude besiqu.Olu lwando lwaluphezulu xa kuthelekiswa nezityalo eziphathwa nge-BA okanye ngaphandle kwehomoni.Nangona i-gibberellic acid kunye ne-cytokinins (CK) ngokubanzi ikhuthaza ukukhula kwezityalo, kwezinye iimeko zineempembelelo ezichaseneyo kwiinkqubo ezahlukeneyo35.Ngokomzekelo, ukusebenzisana okungalunganga kwabonwa ekunyukeni kobude be-hypocotyl kwizityalo eziphathwe nge-GA kunye ne-BA36.Kwelinye icala, i-BA yandise kakhulu umthamo weengcambu (iThebhile 1).Ukunyuka komthamo weengcambu ngenxa ye-BA yangaphandle kuye kwaxelwa kwizityalo ezininzi (umz. I-Dendrobium kunye ne-Orchid)37,38.
Zonke iindlela zonyango zehomoni zandisa inani lamagqabi amatsha.Ukwanda kwendalo kummandla wamagqabi kunye nobude besikhondo ngonyango oludityanisiweyo kuyanqweneleka kurhwebo.Inani lamagqabi amatsha luphawu olubalulekileyo lokukhula kwezityalo.Ukusetyenziswa kwamahomoni angaphandle akuzange kusetyenziswe kwimveliso yentengiso yeLiriodendron tulipifera.Nangona kunjalo, imiphumo yokukhuthaza ukukhula kwe-GA kunye ne-CK, esetyenziswe ngokulinganayo, inokubonelela ngemibono emitsha ekuphuculeni ukulinywa kwesi sityalo.Ngokucacileyo, i-synergistic effect yonyango lwe-BA + GA3 yayiphezulu kune-GA okanye ye-BA elawulwa yodwa.I-asidi ye-Gibberelli inyusa inani lamagqabi amatsha.Njengoko amagqabi amatsha ekhula, ukwandisa inani lamagqabi amatsha kunokunciphisa ukukhula kwamagqabi39.I-GA iye yabikwa ukuba iphucule ukuthuthwa kwe-sucrose ukusuka kwiisinki ukuya kwizitho zomthombo40,41.Ukongezelela, ukusetyenziswa kwangaphandle kwe-GA kwizityalo ezingapheliyo kunokukhuthaza ukukhula kwamalungu ezityalo ezifana namagqabi kunye neengcambu, ngaloo ndlela kuthintele ukuguquka kokukhula kwemifuno ekukhuleni kokuzala42.
Umphumo we-GA ekwandiseni izityalo ezomileyo zingachazwa ngokunyuka kwe-photosynthesis ngenxa yokwanda kwendawo yamagqabi43.I-GA kuxelwe ukuba ibangele ukwanda kwendawo yamagqabi ombona34.Iziphumo zibonise ukuba ukwandisa i-BA yogxininiso kwi-200 mg / L inokunyusa ubude kunye nenani lamasebe esibini kunye nomthamo weengcambu.I-asidi ye-Gibberellic ichaphazela iinkqubo zeselula ezifana nokuvuselela ukwahlukana kweeseli kunye nokwandisa, ngaloo ndlela kuphuculwe ukukhula kwezityalo43.Ukongeza, i-HA yandisa udonga lweseli nge-hydrolyzing isitashi kwiswekile, ngaloo ndlela inciphisa amandla eseli yamanzi, ibangela ukuba amanzi angene kwiseli kwaye ekugqibeleni akhokelele kwi-elongation yeseli44.
