Mhedziso yeCommon Rooting Powder Formulations
1. Indole-3-Acetic Acid (IAA) uye Naphthylacetic Acid (NAA) Rooting Powder
Iyo inonyanya kushandiswa midzi poda pamusika ndeye 50% musanganiswa weIndole-3-Acetic Acid (IAA) uye Naphthylacetic Acid (NAA) (inosanganisira 30% IAA uye 20% NAA). IAA inonzi endogenous chirimwa hormone inowanikwa mumiti; inokonzera kuumbwa kwemidzi yeadventitious uye inokurudzira kupararira kwemashure emidzi. Pakupinda muchirimwa, NAA inokonzera kugadzirwa kwe ethylene; pakudzika kwakadzika, endogenous ethylene inosimudzirawo midzi. Kushandisa nzira: Panzungu negorosi, gadzira mhodzi dzine 20–30 mg/kg; izvi zvinokurumidzisa kumera kwembeu pamwe nekukura kwemidzi.
2. Indole-3-Butyric Acid (IBA) uye Naphthylacetic Acid (NAA) Rooting Powder
Imwe yakajairika midzi poda pamusika ndeye 50% musanganiswa weIndole-3-Butyric Acid (IBA) uye NAA (inosanganisira 40% IBA uye 1% NAA). Rudzi urwu rwehupfu hwemidzi hunoratidzika sehupfu hwakachena kusvika kuhutsvuku; inonyungudika zviri nyore muorganic solvents, inonyungudika zvishoma mumvura inodziya, uye isinganyungudika mumvura inotonhora. Ichi chigadziro chinowanzoshandiswa kukurudzira midzi mukucheka kwemiti uye maruva ekushongedza. Nzira dzekushandisa dzinosanganisira: nzira yekukurumidza kunyura (concentration ye 500-1000 mg / L, kunyura pasi 3-4 cm yekucheka kwemasekonzi 10-15) uye nzira inononoka kunyura (concentration ye10-100 mg / L, kunyura pasi 3-4 cm yekucheka kwemaawa 12-4). Kudzika kwakadzika uye kupfupika kwenguva kunoshandiswa kune zvirimwa zvinodzika midzi zviri nyore, nepo huwandu hwepamusoro uye hurefu hurefu hunoshandiswa kune zvinomera zvakaoma kumidzi.
3. Indole-3-acetic acid (IAA) uye catechol rooting powder
Apo Chirungu ivy cuttings (20-25 cm pakureba) yakarapwa pa basal cut neIAA pamusangano we 10 mg /kg, nhamba yepakati yemidzi pakucheka yaiva 1.3. Zvisinei, apo musanganiswa weIAA (10 mg/kg) uye catechol (5 × 10⁻⁵ mol/L) yakashandiswa kune basal cut, nhamba yemidzi yemidzi pakucheka yakasimuka kusvika ku9.4, ichiratidza hukuru hwe synergistic effect. Tsvagiridzo inoratidza kuti catechol inonyatso kuvharira chiitiko chebiological cheIAA oxidase mukati mekucheka, nekudaro ichibvumira iyo Exogenously yakashandiswa IAA kuti iite zvizere basa rayo rekudzingisa midzi uye zvichikonzera kuita kwepamusoro midzi; Ukuwo, mukusavapo kwekatechol, IAA ichipinda mumuti wechirimwa inokurumidza oxidized uye inactivated neIAA oxidase, zvichiita kuti kuve nekushaya midzi mhedzisiro.
4. Indole-3-acetic acid (IAA) uye saccharin
Uchishandisa mbesa dzebhinzi yeitsvo (2 cm kureba) sechinhu chekuyedza, zvirimwa zvakanyudzwa kwemaawa gumi nematanhatu mumhinduro dze 0.02% indole-3-acetic acid (IAA) kana 0.0019% saccharin (sulfobenzoic acid) isati yasimwa kune greenhouse yekukura kwehydroponic. Mushure memazuva gumi nemaviri ekurapwa, nhamba ye lateral midzi yakaongororwa; kurapwa ne 0.02% IAA chete kwakaguma nemidzi makumi mana nemiviri pamiti, asi kurapwa ne 0.0019% saccharin chete hakuna kuwedzera nhamba ye lateral midzi. Zvisinei, kushandiswa kwakabatanidzwa kweIAA uye saccharin (0.02% + 0.0019%) kwakaguma kune dzakawanda se96 lateral midzi pachirimwa, zvichiratidza kushanda kwakajeka kwe synergistic. Saizvozvo, kushandisa musanganiswa weIAA uye saccharin kumichero yakasimuka zvakanyanya kukurudzira kuumbwa kwemidzi. Ongororo yakazotevera yakaratidza kuti musanganiswa uyu unokurudzira kuumbwa kwemidzi mumbeu dzezvirimwa zvakasiyana zvekurima uye zvehorticultural, kazhinji zvichiratidza synergistic mhedzisiro.
5. Abscisic acid (ABA) uye IAA rooting powder
Abscisic acid (ABA) inhibits gibberellin biosynthesis uye nokudaro inosimudzira midzi mukucheka. Kushandisa cowpea hypocotyls semidziyo yekucheka, kurapa hwaro hwekucheka neABA (S-ABA) chete pazvikamu zve 1–5 mg/kg inosimudzira midzi, sezvakaita kunyura hwaro muIAA (5 mg/kg) chete. Zvisineyi, kushandiswa kwakabatanidzwa kweABA neIAA (1–5 mg/kg ABA + 5 mg/kg IAA) kwakaratidza kushanda kunoita synergistic mukusimudzira kudzika midzi mucowpea hypocotyl cuttings. Apo ABA (1.25–15 mg/kg) yakasanganiswa ne potassium indole-3-butyrate (K-IBA) kana IAA (5–25 mg/kg) kusimudzira midzi kana kukurudzira kukura kwemidzi mumiti yakadai sepizi, matomatisi, mazambiringa, uye populars, kuwedzera kwekuwedzera kwakaonekwa muzviitiko zvakawanda, pamwe nemamwe mamiriro ezvinhu anowirirana; zvisinei, kuwandisa kwakanyanya kweAABA kunodzivisa kudzika midzi. 6. Kusanganiswa kushandiswa kwefulvic acid uye potassium indole-butyrate
Mukuedza kunosanganisira kuchekwa kwemaapuro kwegore rimwe chete, kunyura maapuro kwemaawa 12-24 muchidimbu che 500-fold dilution yefulvic acid chete inosimudzira midzi, sezvo iyo yakanyudzwa fulvic acid inomutsa basa remamwe invertase. Kunyura kwemaawa 12-24 mu potassium indole-butyrate (20 mg/kg) chete yakakurudzira kudzika midzi. Zvisinei, kushandiswa kwakabatanidzwa kwefulvic acid uye indole-butyrate (500-fold dilution plus 20 mg/kg) yakawedzera nhamba yemidzi yakaumbwa.
Iyo inonyanya kushandiswa midzi poda pamusika ndeye 50% musanganiswa weIndole-3-Acetic Acid (IAA) uye Naphthylacetic Acid (NAA) (inosanganisira 30% IAA uye 20% NAA). IAA inonzi endogenous chirimwa hormone inowanikwa mumiti; inokonzera kuumbwa kwemidzi yeadventitious uye inokurudzira kupararira kwemashure emidzi. Pakupinda muchirimwa, NAA inokonzera kugadzirwa kwe ethylene; pakudzika kwakadzika, endogenous ethylene inosimudzirawo midzi. Kushandisa nzira: Panzungu negorosi, gadzira mhodzi dzine 20–30 mg/kg; izvi zvinokurumidzisa kumera kwembeu pamwe nekukura kwemidzi.
