Karolo eaIAA 3-indole acetic acid
E sebelisoa e le ntho e susumetsang kholo ea semela le reagent ea ho hlahloba. IAA 3-indole acetic acid le lintho tse ling tsa auxin tse kang 3-indoleacetaldehyde, IAA 3-indole acetic acid le ascorbic acid li teng ka tlhaho. Selelekela sa 3-indoleacetic acid bakeng sa biosynthesis limela ke tryptophan. Mosebetsi oa mantlha oa auxin ke ho laola kholo ea limela. Ha e khothalletse khōlo feela empa e boetse e na le phello ea ho thibela ho hōla le ho thehoa ha litho tsa 'mele. Auxin ha e fumanehe feela sebakeng se lokolohileng ka har'a lisele tsa semela, empa hape e ka tlamelloa ka thata ho li-macromolecules tsa tlhaho le mefuta e meng ea auxin. Hape ho na le li-auxin tse ka etsang li-complexes tse nang le lintho tse khethehileng, tse kang indole-acetylasparagine, indole-acetyl pentose acetate le indole-acetylglucose, joalo-joalo Sena e ka 'na ea e-ba mofuta oa polokelo ea auxin ka har'a lisele le mokhoa oa ho tlosa chefo ho felisa chefo ea auxin e feteletseng.
Boemong ba lisele, auxin e ka susumetsa karohano ea lisele tsa cambium; E susumelletsa ho lelefatsa lisele tsa lekala le ho thibela kholo ea lisele tsa metso; Khothalletsa phapang ea lisele tsa xylem le phloem, ho nolofatsa ho mela ha li-cuttings, le ho laola morphogenesis ea callus.
Auxin e bapala karolo ho tloha ho seeding ho isa kgolong ya ditholwana maemong a bobedi a setho le sejalo kaofela. Thibelo ea lebone le khubelu le fetolehang la auxin taolong ea bolelele ba mesocotyl ho lipeo; Ha indoleacetic acid e fetela karolong e ka tlaase ea lekala, geotropy ea lekala e etsahala. Ha indoleacetic acid e fetisetsoa lehlakoreng le nang le moriti oa lekala, phototropism ea lekala e etsahala. Indoleacetic acid e baka taolo e holimo; Ho lieha ho hlaha ha makhasi; Auxin e sebelisoang mahlakung e thibela ho tšolloa, ha auxin e sebelisoa qetellong ea lera le arohaneng e khothalletsa ho tšolloa. Auxin e khothalletsa ho thunya, e susumetsa nts'etsopele ea litholoana tse sa amaneng le thobalano, 'me e liehisa ho butsoa ha litholoana.

1. Ho koloba
(1) Nakong ea lipalesa tse felletseng tsa tamati, lipalesa li kolobisoa ka tharollo ea limiligrama tse 3000 ka litha e le ngoe ho etsa hore ho be le litholoana le litholoana tsa tamati, ho etsa litholoana tse se nang peo le ho eketsa sekhahla sa ho beha litholoana.
(2) Ho noa ka metso ho khothalletsa ho mela ha lijalo tse kang liapole, liperekisi, lipere, litholoana tsa lamunu, morara, kiwis, fragole, poinsythia, carnations, chrysanthemums, lirosa, magnolias, rhododendrons, limela tsa tee, metasequoia glyptostroboides le li-pop-up, ho potlakisa sekhahla sa ho tsoala limela. Ka kakaretso, 100-1000mg/L e sebelisetsoa ho kolobisa motheo oa li-cuttings. Bakeng sa mefuta e tloaelehileng ea metso, ho sebelisoa khatello e tlase. Bakeng sa mefuta e seng bonolo ho e mela, sebelisa motsoako o phahameng hanyane. Nako ea ho qoelisoa ke lihora tse ka bang 8 ho isa ho tse 24, e nang le khatello e phahameng ea maikutlo le nako e khuts'oane ea ho koloba.
2. Ho fafatsa
Bakeng sa li-chrysanthemums (tlas'a potoloho ea leseli la lihora tse 9), ho fafatsa tharollo ea 25-400mg / L hang ho ka thibela ponahalo ea lipalesa le ho lieha ho thunya.
