I-Brassinolide, njenge-aisilawuli sokukhula kwezitshalo, ineqhaza elibalulekile ekukhiqizweni kwezolimo kusukela yatholakala.Eminyakeni yamuva nje, ngokuthuthukiswa kwesayensi yezolimo nobuchwepheshe kanye nokushintsha kwesidingo semakethe, i-brassinolide kanye nengxenye yayo eyinhloko yemikhiqizo ehlanganisiwe ivela ngokungapheli.Kusukela emikhiqizweni engaphansi kweyi-100 ebhaliswe ngaphambi kuka-2018, inani lemikhiqizo namabhizinisi ayi-135 seliphindeke kabili.Isabelo semakethe esingaphezu kwebhiliyoni elingu-1 kanye namandla emakethe ama-yuan ayizigidi eziyizinkulungwane ezingu-10 abonisa ukuthi lesi sithako esidala sibonisa amandla amasha.
01
Ukutholwa nokusebenzisa isikhathi kusha
I-Brassinolide iwuhlobo lwe-hormone yesitshalo yemvelo, eyingxenye yamahomoni e-steroid, atholakala okokuqala ku-pollen yokudlwengula ngo-1979, atholakala ku-brassin ekhishwe ngokwemvelo.I-Brassinolide iyisilawuli sokukhula kwezitshalo esisebenza kahle kakhulu, esingakhuphula kakhulu ukukhula kwezakhi zezitshalo futhi sikhuthaze ukuvundiswa ezindaweni eziphansi kakhulu.Ikakhulukazi, ingakhuthaza ukuhlukana kwamangqamuzana nokwelula, ithuthukise ukusebenza kahle kwe-photosynthesis, ithuthukise ukumelana nokucindezeleka, ikhuthaze ukuhlukaniswa kwezimbali zezimbali nokuthuthukiswa kwezithelo, futhi yandise okuqukethwe ushukela wezithelo.
Ngaphezu kwalokho, umphumela wosizo lokuqala ezithonjeni ezifile, ukubola kwezimpande, ukuma okufile nokucisha okubangelwa ukutshala okuphindaphindiwe, izifo, ukulimala kwezidakamizwa, ukulimala okuqandisiwe nezinye izizathu kuyamangalisa, futhi ukusetshenziswa kwamahora angu-12-24 ngokusobala kusebenza kahle, futhi ubungqabavu bubuyiselwa ngokushesha.
Eminyakeni yamuva nje, ngokukhula kwenani labantu emhlabeni wonke kanye nentuthuko ejulile yokukhiqizwa kwezolimo, isidingo semikhiqizo yezolimo siye sakhula.Ukuze kuhlangatshezwane nalesi sidingo, ukwenza ngcono isivuno kanye nekhwalithi yezitshalo kube umgomo oyinhloko wokukhiqizwa kwezolimo.Kulo mongo, isidingo semakethe sabalawuli bokukhula kwezitshalo sikhula kancane kancane.I-Brassinolide isiba amandla okushayela anamandla kakhulu enkathini yamanje yezempilo yezitshalo ngokusebenza kwayo ekwandiseni ukukhiqizwa kanye nokunciphisa ukulawulwa komonakalo.
I-Brassinolide, njengesilawuli sokukhula kwezitshalo esisebenza kahle kakhulu, esine-spectrum ebanzi, yamukelwe abalimi ngenxa yomphumela wayo omangalisayo wokwandisa isivuno ezitshalweni ezihlukahlukene.Ikakhulukazi ekukhiqizeni izitshalo zemali (njengezithelo, imifino, izimbali, njll.) kanye nezitshalo zasensimini (njengelayisi, ukolweni, ummbila, njll.), i-brassinolide isetshenziswa kabanzi.
Ngokusho kwedatha yocwaningo lwemakethe, usayizi wemakethe yomhlaba wonke wabalawuli bokukhula kwezitshalo ukhombise ukukhula okuqinile eminyakeni embalwa edlule.Phakathi kwazo, ingxenye yemakethe ye-brassicolactone iye yanda unyaka nonyaka, yaba yingxenye ebalulekile yemakethe.E-China, isidingo semakethe ye-brassinolide sinamandla ikakhulukazi, sigxile kakhulu ezindaweni ezikhiqiza izitshalo zemali eziseningizimu kanye nezindawo ezikhiqiza izitshalo ezisenyakatho.

Ukusetshenziswa okukodwa kanye nemakethe yenhlanganisela ikhona
Eminyakeni yamuva, imikhiqizo eminingi ehlanganisiwe ene-brassinolide njengengxenye eyinhloko iye yavela emakethe.Le mikhiqizo ivamise ukuhlanganisa ama-brassinolactones nezinye izilawuli zokukhula kwezitshalo, imisoco, njll., ukwenza ukwakheka okuyinhlanganisela ukuze kube nomphumela ohlangene onamandla.
Ngokwesibonelo, inhlanganisela brassinolide namahomoni ezifanai-gibberellin, cytokinin, kanyei-acetic acidingalawula ukukhula kwezitshalo kusuka kuma-engeli amaningi ukuze kuthuthukiswe ukumelana nokucindezeleka kanye nesivuno.Ngaphezu kwalokho, inhlanganisela ye-brassinolide enezici zokulandela umkhondo (njenge-zinc, i-boron, i-iron, njll.) nayo ingathuthukisa kakhulu isimo somsoco wezitshalo futhi ithuthukise amandla azo okukhula.
Ngokuphelelwa yisikhathi kwe-pyrazolide cishe ngo-2015, eminye imikhiqizo ehlanganiswe ne-pyrazolide, i-brassinolide ne-potassium dihydrogen phosphate yathuthukiswa kabanzi emasimini asenyakatho (ummbila, ukolweni, amantongomane, njll.).Ngokushesha kwaholela ekukhuleni kokuthengiswa kwe-brassinolide.
Ngakolunye uhlangothi, amabhizinisi asheshisa ukubhaliswa kwemikhiqizo ehlanganisiwe ehlobene ne-brassinolide, futhi akhuthaze ukusetshenziswa ezimeni ezahlukene.Kuze kube manje, imikhiqizo engu-234 ye-brassinolide ithole ukubhaliswa kwezibulala-zinambuzane, okuyi-124 yayo ixutshwe, ibalwa ngaphezu kuka-50%.Ukunyuka kwale mikhiqizo eyinhlanganisela akuhlangabezani nesidingo semakethe kuphela sabalawuli bezitshalo abasebenzayo nabasebenza ngezindlela eziningi, kodwa futhi kukhombisa ukugcizelela ekuvundiseni okunembayo nokuphathwa kwesayensi ekukhiqizweni kwezolimo.
Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokwenza ngcono izinga lokuqonda kwabalimi, imikhiqizo enjalo izoba nethemba elibanzi lemakethe esikhathini esizayo.I-Brassinolide isetshenziswa kakhulu ekukhiqizeni izitshalo zemali ezifana nezithelo nemifino.Isibonelo, ekukhuleni kwamagilebhisi, i-brassinolide ingathuthukisa izinga lokumisa isithelo, yandise ushukela nobulukhuni besithelo, futhi ithuthukise ukubukeka nokunambitha kwesithelo.Ekulinyweni kukatamatisi, i-brassinolide ingakhuthaza ukuqhakaza kukatamatisi nezithelo, ithuthukise isivuno kanye nekhwalithi yezithelo.I-Brassinolide nayo idlala indima ebalulekile ekukhiqizeni izitshalo zasensimini.Isibonelo, ekulinyweni kwerayisi nokolweni, i-brassinolide ingakhuthaza ukulima, ikhulise ukuphakama kwezitshalo nesisindo sezindlebe, futhi ikhulise isivuno.
I-Brassinolide nayo isetshenziswa kabanzi ekukhiqizeni izimbali nezitshalo zokuhlobisa.Isibonelo, ekulinyweni kwe-rose, i-brassicolactone ingakhuthaza ukuhlukaniswa kwezimbali zezimbali nokuqhakaza, ithuthukise ubuningi kanye nekhwalithi yezimbali.Ekunakekeleni izitshalo ezinamabhodwe, i-brassinolide ingakhuthaza ukukhula kanye namagatsha ezitshalo futhi yandise inani lokuhlobisa.
