1. Auxins uye Gibberellins
Auxins uye gibberellins vanoratidza synergistic mhedzisiro mukusimudzira kukura. Kupfapfaidza zvirimwa zvakasiyana-siyana nemusanganiswa wegibberellins uye auxins panzvimbo dzakakodzera zvinosimudzira kureba kwedzinde; mhedzisiro yekupfapfaidza auxins chete haina kutaurwa pane iyo yegibberellins. Musanganiswa wezviviri izvi unopa mhedzisiro yepamusoro.
Auxins uye gibberellins vanoratidza hukama hunopesana maererano nekusiyana kwepabonde mumagaka. Uku kupesana kunonyanya kuoneka mukutonga kwepabonde remaruva: auxins inokurudzira kusiyanisa kwemaruva echikadzi, asi gibberellins inokurudzira kusiyanisa kwemaruva echirume. Semuenzaniso, kana mbesa dzegaka dzakabatwa neauxin dzozorapwa negibberellins, mhedzisiro yeauxins inogona kurambwa, uye zvinopesana.
2. Auxins uye Cytokinins
Iyo synergistic mhedzisiro pakati pe auxins uye cytokinins inoratidzwa mune yakareba nguva ye cytokinin chiitiko kana maviri mahormone aripo panguva imwe chete. Cytokinins inogona kuwedzera kutakurwa kwepolar kweauxins, nekudaro ichisimudzira auxin chiitiko.
Kupokana pakati peauxins uye cytokinins kunoonekwa mukugadzirwa kwema lateral buds mumiti ye dicotyledonous: cytokinins inokurudzira lateral bud kukura, nepo auxins ichiidzivirira. Nezve kutonga kweapical dominance, yakakwira cytokinin-to-auxin reshiyo inofarira lateral bud kukura, nepo reshiyo yakaderera inochengetedza hutongi hweapical. Nekudaro, zvinhu zvakaita se kinetin, zeatin, uye 6-BA zvinogona kutadzisa kukura-kukurudzira mhedzisiro yeauxins.
3. Auxins uye Ethylene
Auxins inokurudzira ethylene synthesis nekusimudzira basa re ethylene synthase; nekudaro, kuwanda kwakawanda kweauxin kunotadzisa kukura. Ethylene inokanganisa auxins nekudzivisa kutakura kwavo polar uye biosynthesis, pamwe nekusimudzira basa re auxin oxidase.
Kuwanda kwemazinga eauxins kunokonzera kugadzirwa kwe ethylene; kamwechete iyo induced ethylene inosvika pane imwe chikumbaridzo, inodzivisa auxin basa. Izvi zvinoratidza hukama hwemhinduro pakati pezviviri izvi, uye ndizvo chaizvo "mhinduro" iyi nzira inodzora kukura kwechirimwa kwakakodzera. 4. Gibberellins uye Abscisic Acid
Gibberellins uye abscisic acid inoratidza hukama hunopesana: gibberellins inogona kuputsa bud kana mbeu dormancy, nepo abscisic acid inosimudzira dormancy. Vanogovana zvakafanana biosynthetic precursors asi vanogadzirwa pasi pemamiriro akasiyana.
Auxins uye gibberellins vanoratidza synergistic mhedzisiro mukusimudzira kukura. Kupfapfaidza zvirimwa zvakasiyana-siyana nemusanganiswa wegibberellins uye auxins panzvimbo dzakakodzera zvinosimudzira kureba kwedzinde; mhedzisiro yekupfapfaidza auxins chete haina kutaurwa pane iyo yegibberellins. Musanganiswa wezviviri izvi unopa mhedzisiro yepamusoro.
