14-Hydroxylated brassinolide Details
Brassinolide ndiyo yechitanhatu yakakura kukura chirimwa chinodzora chinozivikanwa pasi rese. Iine mabasa ekusimudzira kukura kwezvirimwa, kusimbisa zvirimwa, kuderedza zvirwere, kudzivirira kutonhora nechando, kuwedzera kushanda kwezvinodhaka, kubvisa kukuvadzwa kwezvinodhaka, kuvandudza kunaka, uye kuwedzera goho.
Iyo brassinolide indasitiri mwero inotaura zvakajeka kuti " Brassinolide inoreva huwandu hweimwe kana anopfuura eanotevera macompounds mashanu: 24-epibrassinolide, 22,23,24-trisepibrassinolide, 28-epihomobrassinolide, 28-homobrassinolide uye 14-brassinoydrolidrolide.
Pakati pavo, 14-Hydroxylated brassinolide ndiyo chete brassinolide yakatorwa kubva kune yakasikwa chirimwa pollen. 14-Hydroxylated brassinolide inotorwa kubva muzvirimwa uye ine yakakwira chirimwa chiitiko, inoenderana zvirinani nezvirimwa, yakawedzera hushamwari kwezvakatipoteredza, uye yakachengeteka zvakanyanya kuchengetedza chikafu. Naizvozvo, inonyanya kufarirwa nemusika uye varimi, uye zvigadzirwa zvayo zvekutengesa zviri kumberi muindasitiri yebrassinolide.

1. kuwedzera kushanda
Kuwedzera 14-Hydroxylated paunenge uchishandisa fungicides, zvipembenene, herbicides kana foliar fetiraiza Brassinolide inogona kuvandudza physiological metabolism yezvirimwa, kukurumidza kutorwa uye kuita kweiyo inoshanda zvinongedzo zvemushonga (fertilizer) mhinduro, uye nekukurumidza kuita pachinzvimbo chakanangwa, nekudaro ichiwedzera. kushanda kwemushonga uye kuderedza kuwanda kwemishonga inoshandiswa.
15-Hydroxylated brassinolide inotorwa kubva kune yakasikwa chirimwa zvinyorwa, inoenderana zvirinani nezvirimwa uye yakachengeteka. Kana ikashandiswa pamwe chete nefoliar fetereza yemishonga yezvipembenene, inogona kudzivirira kukuvadzwa kwemishonga (fetereza) uye kuderedza masara emishonga yezvipembenene.
2. Kuwedzera kusasimba kwembesa uye kuderedza kusafara kwezvipembenene nezvirwere
14-Hydroxylated brassinolide inogona kuvandudza uye kuenzanisa mazinga ehomoni ezvirimwa uye kumisa chiitiko cheakawanda immune enzymes muzvirimwa. Haingogone chete kuvandudza kuramba uye kugona kudzoreredza kwezvirimwa kumatambudziko akadai sekusanaya kwemvura, kudonha kwemvura, uye tembiricha yakaderera, asi zvakare kuvandudza kuramba kwezvirimwa kune zvipembenene nezvirwere, kukurudzira metabolism yezvirimwa, nekudaro kuderedza huwandu hwekushandisa zvinodhaka uye kuderedza tupukanana. uye kuramba zvirwere.
3. Kurudzira kukura, kunatsiridza kunaka kwechigadzirwa uye kuwedzera goho
14-Hydroxylated Brassinolide ine yakasanganiswa mhedzisiro ye cytokinin uye gibberellin, inogona kukurudzira kupatsanurwa kwesero uye kurebesa, kukurudzira kukura kwechikamu chepamusoro chezvirimwa uye midzi yemidzi, uye panguva imwe chete kuwedzera chlorophyll zviri mumashizha, kuwedzera mashizha photosynthesis. , kuwedzera kuunganidzwa kwezvigadzirwa zvephotosynthetic, uye kukurudzira kukura kwezvirimwa.
Panguva imwecheteyo, 14-Hydroxylated brassinolide inewo mhedzisiro yekusimudzira mutsauko we lateral buds uye maruva buds, kudzora mwero we endogenous mahomoni muzvirimwa, kusimudzira shanduko yekukura kwezvinomera mukukura kwekubereka, uye kuwedzera huwandu uye mhando yemhando. maruva. Panguva imwecheteyo, inosimudzira kurebesa kwepollen chubhu uye inowedzera chiyero chekuisa michero uye fruiting rate.
14-Hydroxylated brassinolide inodzora chimiro chekupa chikafu, inotakura michero kune michero, inokurudzira kukura uye kukura kwemichero, inoderedza michero isina kusimba uye yakaremara, inosimudzira kunwa kwemuviri uye kushandiswa, uye inowedzera kukurudzira yunifomu kukura, kuwedzera, uye kuchinja kwemavara emichero, nezvimwewo, uye inovandudza goho nemhando yezvigadzirwa zvekurima.
14-Hydroxylated brassinolide yakatorwa kubva mumiti yechisikigo Inofananidzwa nezvimwe zvinhu zvebrassinolide, brassinolide sterol ine basa repamusoro, kusimudzira zviri nani, zviri nyore kutorwa nezvirimwa, uye ine zvakanyanya kugadzikana. Inogona kushandiswa muzvirimwa zvakasiyana uye nguva dzakasiyana dzekukura kukurudzira kukura, kupfura, kuputika kwemichero, kushanduka kwemavara uye zvimwe zvakasiyana mhedzisiro.
4. Dzivisa uye gadzirisa kukanganisa kwezvinodhaka
14-Hydroxylated brassinolide inogona kukurumidza kurongedza mazinga eakasiyana endogenous mahomoni mumuviri, kuunganidza nzira dzakasiyana dzekugadzirisa nucleic acid uye protein synthesis, kugadzirisa akakuvadzwa maseru ezvirimwa kuburikidza necallus chirimwa tishu, uye kudzivirira uye kuderedza kukuvara kwezvinodhaka.
Kugadzirisa uye kudzivirira kukuvara kwezvinodhaka, zvigadzirwa zvine nekukurumidza zvinokonzeresa zvinodiwa. Nomuzvarirwo yakatorwa 14-Hydroxylated brassinolide inobva mumiti. Kana zvirimwa zvakakuvadzwa nemishonga, zvinogona kubatwa zvakananga uye kushandiswa nekupfapfaidza, uye mhedzisiro yacho inoonekwa pazuva rimwe chete. Iine basa repamusoro, rinokurumidza uye rinonyanya kukosha.
