Choyamba, kugwiritsa ntchito nthaka kumatha kulimbikitsa mbewu photosynthesis. Urea palokha imasungunuka mosavuta m'madzi, ndikuthirira kapena kuthira mvula kumabweretsa kuwonongeka kwa nayitrogeni. Kuonjezeranso ma sodium okwanira kwambiri, omwe angalimbikitse mbewu photosynthesis, ndiye kuti, imathandizira kuyamwa kwa nayitrogeni.

Indole Buttyric acid amalimbikitsa kukula kwa mbewu: Indole nteyric acid amalimbikitsa kukula kwa mbewu poyenda mahomoni a endotogenous, zomwe zimapangitsa kuti ma cell agawidwe. Indole mbiti nthiti zitha kuchepetsedwa ndikuwathira masamba kuti apititse patsogolo kukula kwake

GiBberellic acid (GA3): Ntchito yayikulu ya ga3 ndikukula mizu, masamba ofananira, amalimbikitsa maluwa ambiri, ndikuletsa kukhwima komanso kukalamba kwa ma rhizomes pansi.

Njira zabwino kwambiri za zipatso zimakhazikika kuphatikiza bwino kwa Gibberellic acid (ga3) ndi a Crechfornoron. Forellorferoron amayamikiridwa kwambiri chifukwa chothandiza kwambiri kugawana magawo a cell, kusiyanitsa ndi kukulitsa, komanso kapangidwe ka protein. Ntchito yake yachilengedwe ndi yopamwamba kwambiri ka 10 kuposa 6-Benzylalaminapopurine (6-ba), ndipo imagwiritsidwa ntchito kwambiri pa ulimi, kutulutsa zipatso, pongowonjezera zipatso mwachangu komanso kukulitsa zipatso.
