Izitshalo, njengezilwane, zinamaseli akhetheke kakhulu asebenza njengezithunywa. Yize zikhiqiza ngamanani amancane ngokungafani nalokho okwenziwa ngumzimba wethu ngokwesibonelo, yilezo ezilawula izimo zomzimba zezitshalo, njengokukhula noma ukuqhakaza.

Wanna uyazi yini la mahomoni ezitshalo, ebizwa nangokuthi ama-phytohormones, futhi unamuphi umsebenzi? Ake sifike kukho get.

Yini ama-phytohormones?

Ama-phytohormones noma ama-hormone ezitshalo (phyto kusho isitshalo ngesiLatini) yizinto ezikhiqizwa amaseli wezicubu zezitshalo, njengamaqabunga, amagatsha kanye nezimpande. Into ethakazelisa kakhulu ukuthi, yize zikhiqizwa engxenyeni ethile, zingasebenza kwenye, okusho ukuthi lolu hlobo lomlawuli "luhamba" ngaphakathi kwesitshalo.

Yini ama-hormone ezitshalo zezitshalo?

Ama-Phytorhomonas akhiqizwa kumaseli ezitshalo

Lezo ezitholakele kuze kube manje yilezi:

  • I-abscisic acid: ubamba iqhaza ekukhuleni nasekukhuleni kwesitshalo, kanye nasekuvumeleni ukucindezeleka
  • Ama-Auxins: lawula ukukhula kwezitshalo, kubangele ukunwebeka kwamaseli.
  • Ama-cytokinins noma ama-cytokinins: lawula ukukhula, ubudlova, ukufa - okuhleliwe-, ukumelana nezinambuzane nezifo, kanye nokubekezelelana nokuzivikela ezilwaneni ezidla ezinye.
  • I-Ethyleneigesi ekhiqizwa kuzo zonke izitho zesitshalo , futhi uvuse lapho kudingeka khona impendulo kathathu yesitshalo ukuze sikhule kakhulu.
  • IGibberellins: iyangenelela ekuphazanyisweni kokungasebenzi kwezinhlamvu, ekukhuleni kwamafihlekile nezithelo, nasekulawuleni ukukhula kwesiqu.
  • Brassinosteroids: Zibaluleke kakhulu ezitshalweni ezisencane, ngoba zibamba iqhaza ekwandiseni, ekuhlukaniseni nasekuhlukaniseni amaseli, okuthile okuwavumela ukuba akhule.
