Balaoli ba kholo ea limela (PGRs), e tsejoang hape e le li-hormone tsa semela, ke lintho tsa lik'hemik'hale tse amang kholo le nts'etsopele ea limela haholo.Metsoako ena e ka hlaha ka tlhaho kapa ea hlahisoa ka mokhoa oa maiketsetso ho etsisa kapa ho susumetsa lihomone tsa tlhaho tsa semela.

 

Mesebetsi le Bohlokoa ba Balaoli ba Khōlo ea Limela

PGR e laola mekhoa e mengata ea 'mele ea limela, ho kenyelletsa:

Karohano ea Cell le Elongation: Li laola sekhahla sa karohano ea lisele le bolelele, tse susumetsang kholo ea semela ka kakaretso.
Phapang: PGR e thusa ho nts'etsopele ea lisele ka har'a lisele le litho tse fapaneng.
Dormancy le Melemo: Ba bapala karolo ea bohlokoa ho dormancy ea peo le ts'ebetsong ea ho mela.
Lipalesa le Litholoana: PGR e laola nako le sebopeho sa lipalesa le litholoana.
Karabelo ho Tšusumetso ea Tikoloho: Li thusa limela ho arabela liphetohong tsa tikoloho joalo ka khanya, matla a khoheli le ho fumaneha ha metsi.
Likarabo tsa khatello ea maikutlo: PGR e thusa limela ho sebetsana le maemo a khatello ea maikutlo joalo ka komello, letsoai le litlhaselo tsa likokoana-hloko.

 

Tšebeliso ea Litaolo tsa Khōlo ea Limela:

Litaolo tsa kholo ea limela li sebelisoa haholo temong le temong ea lirapa.Li matlafatsa kapa li fetola kholo ea semela le nts'etsopele ho ntlafatsa chai, boleng le ho hanyetsa khatello ea maikutlo.Lisebelisoa tse sebetsang li kenyelletsa:

Ho Ntšetsa Kholiso ea Metso: Li-auxin li sebelisoa ho susumetsa kholo ea metso ea li-cuttings.
Ho Laola Ho Butsoa ha Litholoana: Ethylene e sebelisetsoa ho amahanya ho butsoa ha litholoana.
Ho eketsa chai ea lijalo: Gibberellins e ka sebelisoa ho eketsa boholo ba litholoana le meroho.
Ho Laola Boholo ba Semela: Li-PGR tse ling li sebelisoa ho laola boholo ba limela le lijalo tse khabisang, ho etsa hore li laolehe haholoanyane.

 

Mefuta ea Balaoli ba Khōlo ea Limela:

Ho na le mekhahlelo e mehlano ea mantlha ea taolo ea kholo ea limela:

Auxins: Khothalletsa ho hola ha kutu, ho hola ha metso, le ho arola.Ba kentse letsoho likarabelong tsa leseli le matla a khoheli.
Gibberellins (GA): E susumelletsa ho lelefatsa ha kutu, ho mela ha peo le ho thunya.
Li-cytokinin: Ho khothaletsa karohano ea lisele le ho theha letlobo, le ho liehisa ho mela ha makhasi.
Ethylene: E susumetsa ho butsoa ha litholoana, ho hlohlona ha lipalesa le ho oa ha makhasi;e boetse e arabela maemong a khatello ea maikutlo.
Abscisic Acid (ABA): E thibela kholo le ho khothalletsa ho robala ha peo;e thusa limela ho arabela maemong a khatello ea maikutlo joalo ka komello.

 

Litaolo tsa Khōlo ea Limela tse sebelisoang ka tloaelo:

Brassinolide

Indole-3-Acetic Acid (IAA)
Mosebetsi: Indole-3-acetic acid ke auxin e hlahang ka tlhaho e laolang likarolo tse fapaneng tsa kholo ea limela, ho kenyelletsa le karohano ea lisele, bolelele le phapang.
Lisebelisoa: E sebelisoa ho khothalletsa ho thehoa ha metso ho li-cuttings, ho matlafatsa boemo ba litholoana, le ho laola mekhoa ea ho hōla ha limela.E boetse e sebelisoa moetlong oa lisele ho susumetsa karohano ea lisele le kholo.

Indole-3-Butyric Acid (IBA)
Mosebetsi: Indole-3-butyric acid ke mofuta o mong oa auxin o sebetsang ka ho khetheha ho susumetsang ho qala le nts'etsopele ea metso.

Polokeho ea Balaoli ba Khōlo ea Limela:

Tšireletseho ea balaoli ba kholo ea limela e itšetlehile ka mofuta oa bona, mahloriso le mokhoa oa ho sebelisoa.Ka kakaretso, ha li sebelisoa ho latela litataiso le likhothaletso, li-PGR li bolokehile bakeng sa limela le batho.Leha ho le joalo, tšebeliso e fosahetseng kapa tšebeliso e feteletseng e ka baka liphello tse mpe:

Phytotoxicity: Ho sebelisa litekanyetso tse feteletseng ho ka lematsa limela, ho baka kholo e sa tloaelehang kapa lefu.
Tšusumetso ea Tikoloho: Phallo e nang le li-PGR e ka ama limela le likokoana-hloko tse sa lebelloang.
Bophelo bo Botle ba Batho: Mehato e nepahetseng ea ho sebetsana le ts'ireletso e bohlokoa ho qoba likotsi tse ka bang teng bophelong ba batho.
Mekhatlo e laolang joalo ka Setsi sa Tšireletso ea Tikoloho (EPA) United States le mekhatlo e tšoanang lefatšeng ka bophara e hlokomela tšebeliso e sireletsehileng ea li-PGR ho netefatsa hore ha li hlahise likotsi tse kholo ha li sebelisoa ka nepo.

 

Qetello:

Balaoli ba kholo ea limela ke lisebelisoa tsa bohlokoa temong ea sejoale-joale le temo ea limela, tse thusang taolong le ntlafatsong ea kholo le nts'etsopele ea limela.Ha li sebelisoa ka nepo, li fana ka melemo e mengata joalo ka kotulo e eketsehileng, boleng bo ntlafetseng, le ho hanyetsa khatello ea maikutlo ho betere.Leha ho le joalo, tsamaiso e hlokolosi ke ea bohlokoa ho qoba liphello tse mpe tse ka bang teng ho limela, tikolohong le bophelong ba batho.
