Ndeupi musiyano uripo pakati pezeatin, Trans-zeatin uye zeatin riboside? Zvikumbiro zvavo ndezvipi?

Main mabasa

1. Kurudzira kupatsanurwa kwesero, kunyanya kupatsanurwa kwecytoplasm;

2. Kurudzira kusiyanisa bud. Muchimiro chetishu, inopindirana neauxin kudzora kusiyanisa uye kuumbwa kwemidzi uye buds;

3. Kurudzira kusimudzirwa kwema lateral buds, kubvisa apical dominance, uye nokudaro kutungamirira pakuumbwa kwenhamba yakawanda yeadventitious buds mumutambo wetishu;

4. Kunonoka mashizha senescence, kuderedza kuderera kwehuwandu hwechlorophyll nemapuroteni;

5. Dhonza dormancy yembeu, chinja chiedza kuti chizadzise chiedza chinodiwa nembeu dzakaita sefodya;

6. Kurudzira parthenocarpy mune mimwe michero;

7. Kurudzira kuumbwa kwekutanga kwebud: pamagumo ekucheka kwemashizha uye mune mamwe mosses, inogona kukurudzira kuumbwa kwekutanga kwebud;

8. Kurudzira kuumbwa kwembatatisi tubers.

Iyo inongori neiyo trans chimiro uye ine mhedzisiro yakafanana nezeatin, asi nebasa rakasimba.

Mhedzisiro yaro yakafanana neiyo anti-zeatin. Haisi chete ine mabasa ataurwa pamusoro ezeatin, asi zvakare ine mhedzisiro ye activating gene expression uye metabolic chiitiko.

Kushandisa Nzira

1. Kurudzira kumera kwecallus (inofanira kushandiswa pamwe chete neauxin), fungiro 1mg/L.

2. Kurudzira kuiswa kwemichero, 1001 mg / L zeatin + 5001 mg/L GA3 + 201 mg/L NAA, pfapfaidza pamichero 10, 25, uye 40 mazuva mushure memaruva.

3. Pamuriwo wemashizha, pfapfaidza 201 mg/L kuti mashizha anonoke kutsvuka.

Pamusoro pezvo, kurapa dzimwe mbeu dzembeu kunogona kukurudzira kumera; kurapa padanho rembeu kunogona kukurudzira kukura.

1. Kurudzira kumera kwetishu inonzi callus (inofanira kushandiswa pamwe chete neauxin), pamusangano we 1 ppm;

2. Kurudzira kuiswa kwemichero, 100 ppm ye cytokinin + 500 ppm ye GA3 + 20 ppm ye NAA, pfapfaidza michero 10, 25, uye 40 mazuva mushure memaruva;

3. Kunonoka kutsvuka kwemashizha emiriwo, pfapfaidza 20 ppm;

1. Mumagariro emiti yemiti, iyo inowanzosangana ye anti-cytokinin nucleoside ndeye 1 mg / mL kana kupfuura.

2. Mumutemo wekukura kwemiti, kusungirirwa kwe-anti-cytokinin nucleoside kunowanzova 1 ppm kusvika ku100 ppm, uye kusungirirwa kwakananga kunoenderana nekushandiswa kwakananga uye marudzi emiti. Semuenzaniso, kana uchikurudzira kumera kwetishu inonzi callus, kusanganiswa kwe anti-cytokinin nucleoside ndeye 1 ppm, uye inoda kushandiswa pamwe chete neauxin.

3. Bvisa iyo anti-cytokinin nucleoside powder zvakakwana ne 2-5 mL ye1 M NaOH (kana 1 M acetic acid kana 1 M KOH), wobva wawedzera kaviri-distilled mvura kana ultrapure mvura kuti ugadzirire sarudzo yekuchengetedza ye 1 mg / mL kana yakakwirira. Kurudzira uchiwedzera mvura kuti uve nechokwadi chekusanganisa. Mushonga wekuchengetera unofanirwa kuvharwa uye kuomeswa nechando kuti udzivise kudzokororwa nechando. Dilute mhinduro yekuchengetedza netsika yepakati kusvika kune inodiwa, uye gadzirira mhinduro yekushanda ipapo uye shandisa iyo nekukurumidza.

Mukupedzisa, zeatin, abscisic acid uye abscisic acid nucleotide imwe neimwe ine maitiro avo maererano nekugadzirisa, basa uye kushandiswa kwekushanda.Pakupedzisira, zeatin, abscisic acid uye abscisic acid nucleotide imwe neimwe ine maitiro avo maererano nekugadzirisa, basa uye kushandiswa kwekushanda. Nekudaro, iwo ese anoshanda semagadzirirwo ekukura kwezvirimwa uye anoita basa rakakosha mukusimudzira kukura nekukura kwechirimwa.
