Kana zvasvika kune zvinodzivirira midzi, ndine chokwadi chekuti tese tinozviziva. Zvinonyanya kuzivikanwa zvinosanganisira naphthaleneacetic acid,IAA 3-indole acetic acid, IBA 3-Indolebutyric-acid, nezvimwewo. Asi unoziva here musiyano uripo pakati pe indolebutyric acid ne indoleacetic acid?
【1】Manyuko akasiyana
IBA 3-Indolebutyric-acid ihormone inowanikwa mumiti. Inobva mumiti uye inogona kugadzirwa mumiti.IAA 3-indole acetic acidchinhu chakagadzirwa nenzira yekugadzira, chakafanana neIAA, uye hachiwanikwe mumiti.
【2】Hunhu hwavo hwepanyama nemakemikari hwakasiyana
Asidhi yeIAA 3-indole acetic yakachena ipfu isina ruvara yakaita sekristaro kana kristalo isina ruvara. Inonyungudika nyore nyore muanhydrous ethanol, ethyl acetate uye dichloroethane, inonyungudika mu ether ne acetone, uye hainyungudike mu benzene, toluene, peturu uye chloroform.
IBA 3-Indolebutyric-acid inonyungudika muzvinhu zvinonyungudika zvakaita seacetone, ether uye ethanol, asi hainyungudike zvakanaka mumvura.
【3】Kugadzikana kwakasiyana:
Maitiro ekuita kweIAA 3-indole acetic acid uyeIBA 3-Indolebutyric-acidZvakafanana chaizvo. Zvinogona kukurudzira kupatsanurwa kwemasero, kurebeswa uye kukura, kukonzera kusiyana kwematishu, kuwedzera kupenya kwemasero, uye kukurumidzisa kufamba kweprotoplasm. Zvisinei, IBA 3-Indolebutyric-acid yakagadzikana kupfuura IAA 3-indole acetic acid, asi ichiri nyore kuora kana yaiswa pachiedza. Zviri nani kuichengeta kure nechiedza.
【4】Kugadzirira zvinhu zvakasanganiswa:
Kana zvinodzora zvikawedzerwa, mhedzisiro yacho inowedzerwa kana kutopfuura. Saka, zvichiri kukurudzirwa kuti zviwedzere kushandiswa nezvinhu zvakafanana, zvakaita se sodium naphthoacetate, sodium nitrophenolate, nezvimwewo.
