Umlawuli wokukhula kwezityalo ligama eliqhelekileyo kudidi lwezinto zokwenziwa kweekhemikhali ezinefuthe lolawulo ekukhuleni nasekukhuleni kwezityalo. Ilawula izityalo kubandakanya ukuqhekeka kokulala, ukukhulisa ukuntshula, ukukhuthaza ukukhula kwesiqu kunye namagqabi, ukukhuthaza ukukhula kweentyatyambo, ukukhuthaza ukukhula kweziqhamo, ukwenza iziqhamo ezingenambewu kunye nokuthintela ukukhula kwamagqabi kunye namagqabi, njl.., ngokweemfuno zokwenyani zemveliso, ukusetyenziswa okuguqukayo kwabalawuli ngu ibalulekile kuthetha ukwanda kunye nozinzo Yima kancinci. Ikwanayo Izibonelelo ze "idosi ephantsi, isiphumo esibonakalayo, kunye negalelo eliphezulu lokuphuma"

Zimbini iintlobo: piihormone ezikhanyayo kunye nabalawuli bokukhula kwezityalo. Iihormone zezityalo zizinto ezisebenza ngokwasemzimbeni ezisebenza ngokudityaniswa kwezityalo, zihlala zihanjiswa ukusuka kwindawo yokuqala ukuya kwindawo yesenzo, kwaye zinefuthe elibonakalayo kulawulo nokukhula kwesityalo. Abalawuli bokukhula kwezityalo benziwe ngendlela engeyiyo okanye bakhutshwe kwizinto ezincinci. Banemisebenzi efanayo okanye efanayo njengehormone yezityalo. Banokulawula, balawule, baqondise kwaye bakhuthaze ukukhula kunye nokukhula kwezityalo kunye neehomoni zangaphakathi. Okwangoku, kukho amakhulu ezinto ezenzelwe ukukhula kwezilawuli zokukhulisa izityalo, ezinye zazokubo ziye zasetyenziswa ngokubanzi kwimveliso yezolimo. Isityaloukukhula abalawuli abaye bafunyanwa ikakhulu kubandakanya iintlobo ezintandathu, ezizi Auxin, Gibberellin, Cytokinin, Abscisic, Acid Ethylene kunye Brassin.

Ukusetyenziswa kwabalawuli bokukhula kwezityalo

Ngokwendlela eyahlukileyo ukusetyenziswa, Khuthaza ukhula lwenkohlakalo kwaye nyusa ukusika ingcambuing ukusetyenziswa gabalala 3-i-indole acetic acid (IAA), 3-i-indole butyric acid (IBA), 1-I-naphthalene acetic acid (NAA), kunye ne-ABT ye-rooting powder. B9, paclobutrazol, chlormequat, kunye ethephon sebenzisa ukubambezela ukukhula. IGibberellin zihlala zisebenzisa khuthaza ukukhula kwesiqu kunye namagqabi, yenza Ukudibanisa iintyatyambo kunye nokutyatyamba kwangaphambili, kukhuthaza ukuntshula kweembewu kunye nezilimo eziyizigaxa, zikhuthaza ukukhula kweziqhamo, zonyusa amaxabiso eziqhamo, okanye zenze iziqhamo ezingenambewu, njl.. Bona have iye yasetyenziswa ngokubanzi kulinywe iitapile, iitumato, irayisi, ingqolowa, umqhaphu, iimbotyi zesoya, ertyisi, icuba, imithi yeziqhamo kunye nezinye izityalo.

Okwangoku, zikhona ezininzi Iindidi zabalawuli bokukhula kwezityalo ababhalisiweyo nabasetyenziswa eChina. Eyona misebenzi yabo iphambili yile: Yongeza ixesha lokulala / lokungalali kwaye Ukukhuthaza ukuhluma, ukukhuthaza ukukhula kweengcambu, ukukhuthaza / ukuthintela ukukhula kwesiqu kunye namagqabi, ukukhuthaza / ukuthintela ukwenziwa kweentyatyambo., ukunciphisa / ukugcina ye iintyatyambo kunye neziqhamo, ezinciphisa iintyatyambo zamabhinqa / iintyatyambo zesilisa, ukwandisa ixesha lokudubula, ukugcina iintyatyambo ezisikiweyo zintsha, zenza iziqhamo ezingenambewu, ukukhuthaza imibala yeziqhamo, ukukhuthaza / ukulibazisa ukukhula kweziqhamo, ukulibaziseka kwesense, ukonyusa i-amino acid / iproteni / umxholo weswekile, ukwandisa fkumxholo, ukuphucula ukuxhathisa uxinzelelo, njl.
