Chii chinonzi mahormone emiti?

Zvirimwa, semhuka, zvine masero akasarudzika anoita sevatumwa. Kunyangwe vachizviburitsa muhuwandu hushoma, kusiyana neizvo zvinogadzirwa nemuviri wedu semuenzaniso, ndidzo dzinogadzirisa zvinoitika zvemuviri zvezvirimwa, sekukura kana kutumbuka.

Wanna ziva ndedzipi idzi mahormone emiti, inonziwo phytohormones, uye ine basa rei? Zvakanaka ngatisvike pairi 🙂.

Chii chinonzi phytohormones?

Phytohormones kana mahormone emiti (phyto zvinoreva chirimwa muchiLatin) izvo zvinhu zvinogadzirwa nemasero ezvirimwa zvemiti, semashizha, matavi uye kunyange midzi. Chinhu chinonyanya kufadza ndechekuti, kunyange hazvo zvichigadzirwa mune chimwe chikamu, zvinogona kuita mune chimwe, zvinoreva kuti rudzi urwu rwevatongi "runofamba" mukati memuti.

Ndeapi mahormone emiti yezvirimwa?

Iwo akawanikwa kusvika parizvino ndeaya:

• Abscisic asidhi: inotora chikamu mukusimudzira uye kukura kwechirimwa, pamwe nekugadzirisa kushushikana.
• Auxins: gadzirisa kukura kwezvirimwa, zvichikonzera kureba kwemasero.
• Cytokinins kana cytokinins: gadzirisa kukura, senescence, kufa-yakarongedzwa-, kuramba zvipukanana nezvirwere, pamwe nekushivirira nekudzivirira pazvikara.
• Ethylene: iri gasi rinogadzirwa munhengo dzese dzemuti, uye rine mabasa mazhinji: kumera kwembeu, kudzora kwekukura, kuibva kwemichero, kukurudzira senescence yemasero akura kwazvo eiyo xylem uye mashizha nemaruva. , uye nekutsamwisa pazvinenge zvichidikanwa mhinduro katatu yemuti kuti ikure zvakanyanya.
• Gibberellins: inopindira mukukanganisa kwekugara kwembeu, mukukura kwemabukira nemichero, uye nemutemo wekukura kwehunde.
• Brassinosteroids: Dzinonyanya kukosha kune zvidyarwa zvidiki, sezvo ivo vachitora chikamu mukuwedzera, kupatsanura uye kupatsanura masero, chimwe chinhu chinovatendera kukura.

Iwe wafungei nezvenyaya iyi? 🙂
