Isilawuli sokukhula kwezitshalo yigama elijwayelekile lesigaba sezinto zokwenziwa zamakhemikhali ezinomphumela wokulawula ekukhuleni nasekukhuleni kwezitshalo. Ilawula izitshalo kufaka phakathi ukuphuka kokulala, ukukhuthaza ukuhluma, ukukhuthaza ukukhula kwesiqu kanye namaqabunga, ukukhuthaza ukwakheka kwezimbali, ukukhuthaza ukuvuthwa kwezithelo, ukwakha izithelo ezingenambewu nokuvimbela ukukhula kwamaqabunga neziqu, njll.., ngokwezidingo zangempela zokukhiqiza, ukusetshenziswa okuguqukayo kwabalawuli kuyinto kubalulekile kusho ukwanda nokusimamisa Veza. Kubuye futhi izinzuzo ze "isilinganiso esiphansi, umphumela obalulekile, kanye nesilinganiso sokufaka okukhiphayo okuphezulu"

Kunezinhlobo ezimbili: pama-lant hormone kanye nabalawuli bokukhula kwezitshalo. Ama-hormone ezitshalo ayizinto ezisebenza ngomzimba ezincane ezihlanganiswe ezitshalweni, imvamisa zithuthwa zisuka endaweni yokuhlanganiswa ziye endaweni yesenzo, futhi zinomthelela omkhulu wokulawula ekukhuleni nasekuthuthukisweni kwesitshalo. Izilawuli zokukhula kwezitshalo zihlanganiswa ngokwenziwa noma zikhishwe ezintweni ezincane eziphilayo. Banemisebenzi efanayo noma efanayo njengamahomoni ezitshalo. Bangalawula, balawule, baqondise futhi bakhuthaze ukukhula nokuthuthuka kwezitshalo kanye namahomoni endo native. Njengamanje, kunamakhulu ezilawuli zokukhulisa izitshalo ezenziwe ngobuciko, ezinye zazokubo zisetshenziswe kabanzi ekukhiqizeni ezolimo. Isitshaloukukhula abalawuli abatholwe ikakhulukazi bafaka izinhlobo eziyisithupha, okuyizinto Auxin, Gibberellin, Cytokinin, Ai-bscisic, Acid Ethylene futhi Brassin.

Ukusetshenziswa kwabalawuli bokukhula kwezitshalo

Ngokuya ngokuhlukile ukusetshenziswa, khuthaza ukhula lwenkohlakalo egcwele futhi khuthaza ukusika impandeing ukusetshenziswa okujwayelekile 3-i-indole acetic acid (IAA), 3-i-indole butyric acid (IBA), 1-i-naphthalene acetic acid (NAA), kanye ne-ABT yokuqothula i-powder. B9, paclobutrazol, chlormequat, ne-ethephon sebenzisa ukubambezela ukukhula. UGibberellin imvamisa sebenzisa ku ukugqugquzela ukukhula kweziqu namaqabunga, yenza i-bolting ne-flowering phambilini, ikhuthaza ukuhluma kwembewu nezilimo eziyizigaxa, zikhuthaza ukukhula kwezithelo, zenyuse amanani ezithelo, noma zenze izithelo ezingenazimbewu, njll.. Bona have isetshenziswe kabanzi ekutshalweni kwamazambane, utamatisi, ilayisi, ukolweni, ukotini, ubhontshisi, uphizi, ugwayi, izihlahla zezithelo nezinye izitshalo.

Njengamanje, zikhona eziningi izinhlobo zezilawuli zokukhula kwezitshalo ezibhalisiwe nezisetshenziswa eChina. Imisebenzi yabo eyinhloko yilena: ukwelula isikhathi sokulalisa isitho / ukugqekeza ukulala futhi ukugqugquzela ukuhluma, ukukhuthaza ukwanda kwezimpande, ukukhuthaza / ukuvimbela ukukhula kweziqu kanye namaqabunga, ukukhuthaza / ukuvimbela ukwakheka kwezimbali, ukuncipha / ukulondolozwa ka izimbali nezithelo, kunciphisa izimbali zesifazane / izimbali zesilisa, ukunweba isikhathi sokuqhakaza, ukugcina izimbali ezisikiwe zisanda, zakha izithelo ezingenazimbewu, ukukhuthaza umbala wezithelo, ukukhuthaza / ukubambezela ukuvuthwa kwezithelo, ukubambezeleka kwe-senescence, ukwandisa okuqukethwe kwe-amino acid / amaprotheni / okuqukethwe ushukela, kuyanda fkokuqukethwe, thuthukisa ukumelana nengcindezi, njll.
