Kukura kwezvidyarwa zvinosanganisira akawanda marudzi, imwe neimwe iine yayo yakasarudzika basa uye chiyero chekushandisa. Aya anotevera ndeamwe Plant kukura anodzora uye maitiro ayo anoonekwa zvakanyanya kuve nyore kushandisa uye anoshanda:

Plant growth regulators (PGRs) inogadzirwa zvemakemikari makomisheni ane zvakafanana physiological mhedzisiro uye akafanana makemikari zvimiro seendogenous chirimwa mahomoni. Plant growth regulator ndeyechikamu chakafara chemishonga yezvipembenene uye ikirasi yemishonga inouraya zvipembenene inodzora kukura kwechirimwa nekukura, kusanganisira maumbirwo emakomisheni akafanana nemahomoni echirimwa echisikigo nemahomoni anotorwa zvakananga kubva kuzvisikwa.

Auxin is indole-3-acetic acid, ine molecular formula C10H9NO2. Ndiyo hormone yekutanga kuwanikwa yekusimudzira kukura kwechirimwa. Shoko reChirungu rinobva paizwi rechiGiriki rokuti auxein (to grow). Chigadzirwa chakachena che indole-3-acetic acid ikristaro chena uye isinganyunguriki mumvura. Kunyungudika zviri nyore muorganic solvents senge ethanol uye ether. Iyo inogadziriswa nyore nyore uye inoshanduka kuita tsvuku tsvuku pasi pechiedza, uye kuita kwayo kwemuviri kunoderedzwa zvakare. Indole-3-acetic acid mumiti inogona kunge iri munzvimbo yakasununguka kana yakasungwa (yakasungwa) mamiriro.

Musiyano mukuita: 24-epibrassinolide iri 97% inoshanda, nepo 28-homobrassinolide iri 87% inoshanda. Izvi zvinoratidza kuti 24-epibrassinolide ine basa repamusoro pakati pemakemikari akagadzirwa brassinolides.
