Makhalidwe a Indole-3-butyric acid potaziyamu mchere IBA-K
Indole-3-butyric acid potassium mchere (IBA-K) ndi mchere wa potaziyamu wa Indole-3-butyric acid. Imakhala ndi zinthu zokhazikika ndipo imagwiritsidwa ntchito kulimbikitsa kukula kwa mizu ya capillary (mizu yabwino) mu mbewu. Iwo panopa anazindikira monga mmodzi wa ogwira ntchito rooting akupezeka pa msika. Itha kugwiritsidwa ntchito ngati feteleza woyambira kapena kuthirira (kuthira), komanso imatha kuphatikizidwa ndi feteleza wapawiri, feteleza wosakanizika, feteleza wa BB, ndi zina zophatikiza feteleza. Mukagwiritsidwa ntchito kufalitsa mbande kudzera mu cuttings, tikulimbikitsidwa kuti tigwiritse ntchito pamodzi ndi Sodium 1-Naphthyl Acetic Acid (Na-NAA) - monga Na-NAA imalimbikitsa kukula kwa mizu yayikulu-komanso zotsatira zabwino, kuwonjezera kwa Atonik kumalimbikitsidwa kwambiri.
IBA-K ndi chowongolera kukula kwa mbewu chomwe chimapangidwira kulimbikitsa mizu. Zimapangitsa mapangidwe adventitious mizu mu mbewu. Akagwiritsidwa ntchito pogwiritsa ntchito njira monga kupopera mbewu mankhwalawa kapena kuviika muzu, amalowetsedwa kudzera m'zigawo zosiyanasiyana za zomera-monga masamba ndi njere-ndipo amasamutsidwa m'thupi lonse la zomera, kumene zimachulukana pamalo okulirapo. Kuchulukana kumeneku kumapangitsa kuti ma cell agawikane ndipo kumapangitsa kuti pakhale mizu yodziwikiratu, zomwe zimapangitsa kuti mizu ikhale ndi kachulukidwe kakang'ono, kakulidwe kowongoka, makulidwe ochulukirapo, komanso tsitsi lambiri. Amasungunuka mosavuta m'madzi ndipo amawonetsa zochitika zamoyo zambiri kuposa IBA yeniyeni. Ngakhale kuti imawola pang'onopang'ono pansi pa kuwala kwamphamvu, kapangidwe kake ka maselo kumakhalabe kokhazikika pamene kasungidwa pansi pa mikhalidwe yotetezedwa ndi kuwala.
1. IBA-K imagwira ntchito pazigawo zonse zomwe zikukula mokangalika za mmera - kuphatikiza mizu, mphukira zanthete, ndi zipatso - ndipo imakhudza kwambiri kugawanika kwa maselo ndi kukulitsa kukula mkati mwazigawo za mbewu zomwe imayikidwa.
2. IBA-K imadziwika ndi mphamvu zake zokhalitsa komanso zomwe zimafuna kuchitapo kanthu.
3. IBA-K imalimbikitsa kukula kwa mizu yatsopano, imayambitsa mapangidwe a mizu ya primordia, ndipo imayambitsa chitukuko cha mizu yodabwitsa mu cuttings. Ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri pakufalitsa ndi kubzala maluwa okongola, nazale, ndi zinthu zina zambewu kudzera muzodula.
4. IBA-K imasonyeza kukhazikika kwapamwamba poyerekeza ndi IBA yoyera; imasungunuka m'madzi kwathunthu komanso yotetezeka kugwiritsa ntchito, ndikupangitsa kuti ikhale yabwino kwambiri polimbikitsa mizu ndi kukula.
