Sodium o-nitrophenolate inogona kushandiswa sechirimwa cell activator, iyo inogona kukurumidza kupinda mukati mechirimwa muviri, kukurudzira kuyerera kwesero protoplasm, uye kukurumidza kudzika midzi yezvirimwa.

Mhando huru dzemidzi yechirimwa nedzinde dzekuwedzera dzinosanganisira chlorformamide uye choline chloride/naphthyl acetic acid.

Choline chloride inogadzirisa kukura kwechirimwa inogona kukurudzira kukura nekukurumidza kwemidzi yepasi uye machubhu, kunatsiridza goho uye kunaka. . Inogona zvakare kudzora photosynthesis yemashizha uye inhibit photorespiration, nekudaro ichikurudzira kuwedzera kwepasi pevhu machubhu.

Miti inogadzirisa kukura kwezvirimwa inosimudzira kukura kwembesa kunyanya inosanganisira anotevera marudzi:Gibberellic Acid (GA3): Gibberellic Acid inodzora kukura kwechirimwa inokwanisa kusimudzira kukura nekukura kwezvirimwa, kuita kuti zvikure nekukurumidza, kuwedzera goho, uye kuvandudza kunaka. Yakakodzera zvirimwa zvakaita sedonje, matomatisi, miti yemichero, mbatatisi, gorosi, soya beans, fodya, uye mupunga.

Kudzika midzi ndeimwe yematanho akakosha ekukura kwechirimwa uye yakakosha zvikuru pakukura, kukura nekuberekana kwezvirimwa. Nokudaro, nzira yekusimudzira midzi yemiti inyaya inokosha mukurima kwemiti. Ichi chinyorwa chichakurukura nzira yekusimudzira midzi yemiti kubva kune zvikamu zvehutano hwehutano, zvakatipoteredza, uye nzira dzokurapa.
