Cov txheej txheem ntawm micropropagation tuaj yeem muab faib ua plaub theem:

  • Kev pib theem . Ib daim ntawm cov ntaub so ntswg (hu ua explant) yog (a) txiav los ntawm cov nroj tsuag, (b) disinfested (tshem tawm cov kab mob saum npoo), thiab (c) muab tso rau hauv nruab nrab.
  • Multiplication theem .
  • Rooting los yog preplant theem .
  • Acclimatization.

Ua raws li qhov kev pom no, dab tsi yog theem ntawm cov ntaub so ntswg kab lis kev cai?

Kab lis kev cai tuaj yeem muab faib ua plaub theem : (i) Thaum xub thawj theem , cov nroj tsuag tsim nyog (hu ua explants) raug txiav mus rau hauv me me pieces, deg sterilized nrog tshwj xeeb tshuaj tiv thaiv kab mob thiab ces inoculated rau semi-khoom. kab lis kev cai xov xwm.

Kuj Paub, dab tsi yog hauv vitro micropropagation? Micropropagation yog cov vegetative sai kev nthuav tawm ntawm cov nroj tsuag hauv qab vitro tej yam kev mob ntawm lub teeb siv siab, tswj qhov kub thiab txias nruab nrab cov as-ham. Cov txheej txheem tau siv rau ntau tus lej ntawm kev lag luam vegetatively propagated nroj tsuag.

Tsuas yog li ntawd, plaub theem tseem ceeb ntawm cov ntaub so ntswg yog dab tsi?

Micropropagation yog propagation ntawm cov nroj tsuag kab lis kev cai . Muaj plaub theem mus rau micro-propagation.

Cov theem no yog:

  • Theem I Kev Tsim Kho.
  • Theem II Multiplication.
  • Theem III Rooting.
  • Theem IV Acclimatization.

Dab tsi yog cov ntaub so ntswg kab lis kev cai ntawm micropropagation?

Micropropagation yog cov cov txheej txheem kab lis kev cai siv rau ceev vegetative multiplication ntawm ornamental nroj tsuag thiab txiv hmab txiv ntoo ntoo. Qhov no txoj kev ntawm kab lis kev cai tsim ntau yam nroj tsuag. Txhua yam ntawm cov nroj tsuag no yuav yog genetic zoo tib yam rau thawj cov nroj tsuag los ntawm qhov chaw lawv tau cog.
