14-Hydroxylated brassinolide Imininingwane
I-Brassinolide iyisilawuli sokukhula kwezitshalo esikhulu sesithupha esibonwa emhlabeni wonke. Inemisebenzi yokukhuthaza ukukhula kwezitshalo, ukuqinisa izitshalo, ukunciphisa izifo, ukuvimbela amakhaza nesithwathwa, ukuqinisa ukusebenza kwezidakamizwa, ukuqeda ukulimala kwezidakamizwa, ukuthuthukisa izinga, nokwandisa isivuno.
Izinga lemboni ye-brassinolide lisho ngokusobala ukuthi "I-Brassinolide isho isamba senhlanganisela eyodwa noma ngaphezulu kwezihlanu ezilandelayo: 24-epibrassinolide, 22,23,24-trisepibrassinolide, 28-epihomobrassinolide, 28-homobrassinolide kanye ne-14-Hydrolated brassinolide.
Phakathi kwazo, i-14-Hydroxylated brassinolide iyona kuphela i-brassinolide ekhishwe kumpova yezitshalo zemvelo. I-14-Hydroxylated brassinolide ithathwa ezitshalweni futhi inomsebenzi wezitshalo ophakeme kakhulu, ihambisana kangcono nezitshalo, inobungani nemvelo, futhi ivikeleke kakhulu ekuphepheni kokudla. Ngakho-ke, ithandwa kakhulu yimakethe nabalimi, futhi ukuthengiswa kwemikhiqizo yayo kusekude kakhulu embonini ye-brassinolide.

Indima ye-14-Hydroxylated brassinolid
1. ukwanda ukusebenza ngempumelelo
Ukwengeza i-14-Hydroxylated lapho usebenzisa ama-fungicides, insecticides, herbicides noma umanyolo we-foliar Brassinolide ingathuthukisa umzimba wezitshalo, isheshise ukumuncwa kanye nokuqhutshwa kwezithako ezisebenzayo zomuthi (umanyolo) isisombululo, futhi isebenze ngokushesha endaweni okuhlosiwe, ngaleyo ndlela ithuthukise. ukusebenza kahle komuthi kanye nokunciphisa inani lezibulala-zinambuzane ezisetshenziswayo.
I-15-Hydroxylated brassinolide itholakala ezingxenyeni zezitshalo zemvelo, inokuhambisana kangcono nezitshalo futhi iphephe kakhudlwana. Uma isetshenziswa kanye nomanyolo we-pesticide foliar, ingagwema ngempumelelo ukulimala kwezidakamizwa (umanyolo) futhi inciphise izinsalela zezibulala-zinambuzane.
2. Khulisa ukumelana nezitshalo futhi unciphise ukumelana nezinambuzane nezifo
I-14-Hydroxylated brassinolide ingathuthukisa futhi ilinganise amazinga e-hormone yezitshalo futhi ivule umsebenzi wama-enzyme amaningi omzimba ezitshalweni. Ngeke nje ithuthukise ukumelana nekhono lokubuyisela izitshalo ezinkingeni ezifana nesomiso, ukugcwala kwamanzi, kanye nezinga lokushisa eliphansi, kodwa futhi ithuthukise ukumelana kwezitshalo ezinambuzaneni nezifo, ikhuthaze umzimba wezitshalo, ngaleyo ndlela yehlise inani lokusetshenziswa kwezidakamizwa futhi inciphise izinambuzane. kanye nokumelana nezifo.
3. Khuthaza ukukhula, uthuthukise ikhwalithi yomkhiqizo futhi ukhulise isivuno
I-14-Hydroxylated Brassinolide inemiphumela ehlanganisiwe ye-cytokinin ne-gibberellin, engakhuthaza ukuhlukana kwamaseli nokwelula, ikhuthaze ukukhula kwengxenye yezitshalo engaphezulu komhlaba kanye nesistimu yezimpande, futhi ngesikhathi esifanayo ikhulise okuqukethwe kwe-chlorophyll emaqabunga, ithuthukise i-photosynthesis yamaqabunga. , ukwandisa ukunqwabelana kwemikhiqizo ye-photosynthetic, futhi kukhuthaze ukukhula kwezitshalo.
Ngasikhathi sinye, i-14-Hydroxylated brassinolide nayo inomphumela wokuqhakambisa ukuhlukaniswa kwama-lateral buds kanye nezimbali zezimbali, ilawula izinga lamahomoni angapheli ezitshalweni, ikhuthaze ukuguqulwa kokukhula kwezitshalo ekukhuleni kokuzala, nokwandisa inani nekhwalithi yezitshalo. ukuqhakaza. Ngesikhathi esifanayo, ikhuthaza ukunwetshwa kwamashubhu empova futhi ikhuphule izinga lokumisa izithelo kanye nezinga lezithelo.
I-14-Hydroxylated brassinolide ilawula ukwakheka kokunikezwa kwezakhi, ihambisa izakhi ezitshalweni, ikhuthaze ukukhula nokuthuthukiswa kwezithelo, inciphise izithelo ezibuthakathaka nezikhubazekile, ikhuthaze ukumuncwa kwezakhi kanye nokusetshenziswa, futhi ithuthukise ukukhula okufanayo, ukwanda, nokushintsha umbala wezithelo, njll., futhi ithuthukisa isivuno kanye nezinga lemikhiqizo yezolimo.
I-14-Hydroxylated brassinolide ekhishwe ezitshalweni zemvelo Uma kuqhathaniswa nezinye izithako ze-brassinolide, i-brassinolide sterol inomsebenzi ophezulu, umphumela wokuphromotha ongcono, kulula ukumuncwa izitshalo, futhi unomphumela ozinzile. Ingasetshenziswa ezitshalweni ezahlukene kanye nezikhathi zokukhula ezihlukene ukuze kuthuthukiswe ukukhula, ukuhluma, ukuvuvukala kwezithelo, ukushintsha kombala neminye imiphumela ehlukene.
4. Gwema futhi uxazulule ukulimala kwezidakamizwa
I-14-Hydroxylated brassinolide ingaxhumanisa ngokushesha amazinga amahomoni ahlukahlukene angapheli emzimbeni, ihlanganise izindlela ezahlukahlukene zokulungisa i-nucleic acid kanye nokuhlanganiswa kwamaprotheni, ilungise amangqamuzana ezitshalo alimele ngezicubu zezitshalo ze-callus, futhi ivimbele futhi inciphise ukulimala kwezidakamizwa.
Ukuxazulula nokugwema ukulimala kwezidakamizwa, imikhiqizo enemiphumela esheshayo iyadingeka. I-14-Hydroxylated brassinolide ekhishwe ngokwemvelo ivela ezitshalweni. Lapho izitshalo zonakaliswa izidakamizwa, zingamuncwa ngokuqondile futhi zisetshenziswe ngokufafaza, futhi umphumela ubonakala ngalolo suku. Inomsebenzi ophezulu, imiphumela esheshayo nebaluleke kakhulu.
Izinga lemboni ye-brassinolide lisho ngokusobala ukuthi "I-Brassinolide isho isamba senhlanganisela eyodwa noma ngaphezulu kwezihlanu ezilandelayo: 24-epibrassinolide, 22,23,24-trisepibrassinolide, 28-epihomobrassinolide, 28-homobrassinolide kanye ne-14-Hydrolated brassinolide.
