Zeziphi izichumisi ezilawulayo zamagqabi?
Olu hlobo lwesichumisi se-foliar luqulethe izinto ezilawula ukukhula kwezityalo, ezifana ne-auxin, ihomoni kunye nezinye izithako.
Umsebenzi wayo ophambili kukulawula ukukhula nophuhliso lwezityalo. Ifanelekile ukusetyenziswa kwizigaba zokuqala kunye neziphakathi zokukhula kwezityalo.
Ngexesha lenkqubo yokukhula, izityalo azikwazi nje ukudibanisa izondlo ezininzi kunye nezinto ezakhiweyo, kodwa ziphinde zivelise ezinye izinto ezisebenzayo ze-physiologically, ezibizwa ngokuba yi-endogenous plant hormones. Nangona la mahomoni akhoyo kwixabiso elincinci kwizityalo, anokulawula kwaye alawule ukukhula okuqhelekileyo kunye nokuphuhliswa kwezityalo, ezifana nokukhula kweeseli kunye nokwahlula, ukuhlukana kweeseli, ukwakhiwa kwamalungu, ukulala kunye nokuhluma, i-tropism yezityalo, uvakalelo, ukuvuthwa, ukuchithwa, ukwaluphala, njl., zonke ezilawulwa ngokuthe ngqo okanye ngokungathanga ngqo ngamahomoni. Ezinye izinto eziphilayo ezenziwe ngobuqhetseba kwiifektri ezinokwakheka kweemolekyuli ezifanayo kunye nefuthe lomzimba kwiihomoni zezityalo zendalo zibizwa ngokuba ngabalawuli bokukhula kwezityalo.
Izilawuli zokukhula kwezityalo kunye neehomoni zezityalo zibizwa ngokubanzi ngokuba ngabalawuli bokukhula kwezityalo.
Okwangoku, izilawuli zokukhula kwezityalo ezisetyenziswa ngokuqhelekileyo kwimveliso zi
①Auxin:ezifana ne-Naphthalene acetic acid (NAA), i-Indole-3-acetic acid, i-anti-drop agent, i-2,4-D, njl.;
②Gibberellic Acid:Kukho iintlobo ezininzi ze-Gibberellic Acid compounds, kodwa i-Gibberellic Acid esetyenziswa kwimveliso ikakhulu (GA3) kunye ne-GA4, GA7, njl.;
③iiCytokinins:njenge 5406;
④Ethylene:I-Ethephon;
⑤Iinhibitors zokukhula kwezityalo okanye iiretardants:I-Chlormequat Chloride (CCC), i-chlorambucil, i-Paclobutrazol (i-Paclo), iplastiki, njl. Ukongeza koku ngasentla, kukho i-Brassinolide (BRs), i-zeati, i-abscisic acid, i-defoliants, i-triacontanol, njl.
Umsebenzi wayo ophambili kukulawula ukukhula nophuhliso lwezityalo. Ifanelekile ukusetyenziswa kwizigaba zokuqala kunye neziphakathi zokukhula kwezityalo.

Ezinye izinto eziphilayo ezenziwe ngobuqhetseba kwiifektri ezinokwakheka kweemolekyuli ezifanayo kunye nefuthe lomzimba kwiihomoni zezityalo zendalo zibizwa ngokuba ngabalawuli bokukhula kwezityalo.
