Wowongolera kukula kwa mbewu: S-abscisic acid
S-abscisic acid imakhala ndi zotsatira za thupi monga kuchititsa kuti masamba awonongeke, kukhetsa masamba ndi kulepheretsa kukula kwa maselo, komanso amadziwika kuti "dormant hormone".
Idapezeka cha m'ma 1960 ndipo idatchulidwa molakwika chifukwa idakhudzana ndi kugwa kwamasamba. Komabe, tsopano zikudziwika kuti kugwa kwa masamba a zomera ndi zipatso kumayambitsidwa ndi ethylene.
S-abscisic acid ndi wobiriwira wobiriwira,S-abscisic acid ndi chomera chachilengedwe chogwira ntchito.
Zinthu zachilengedwezi zimapezeka kwambiri muzomera. Mwachilengedwe amakhala mu zipatso, ndiwo zamasamba ndi mbewu zomwe anthu amadya ndipo ndizotetezeka kwa anthu komanso chilengedwe.
Zopangira zomwe zimagwiritsidwa ntchito popanga ukadaulo wa abscisic acid ndizopanda poizoni komanso zopanda vuto zaulimi komanso zam'mbali. Imapezedwa kudzera mu nayonso mphamvu ya tizilombo tating'onoting'ono, popanda kuwonjezera zinthu zovulaza kapena zinthu, ndipo palibe zinthu zapoizoni pamapangidwe ake.
Kugwiritsa ntchito S-abscisic acid
1.S-abscisic acid ndi njira yoletsa kumera kwa mbewu
S-abscisic acid atha kugwiritsidwa ntchito posungira mbewu komanso kuteteza kameredwe.
2. S-abscisic acid ikhoza kulimbikitsa kudzikundikira kwa zinthu zosungiramo mbewu ndi zipatso, makamaka kudzikundikira kwa mapuloteni osungira ndi shuga.
Kugwiritsa ntchito asidi abscisic kumayambiriro kwa kukula kwa mbewu ndi zipatso kungathe kukwaniritsa cholinga choonjezera zokolola za mbewu zambewu ndi mitengo ya zipatso.
3. S-abscisic acid imatha kupititsa patsogolo kuzizira ndi chisanu kwa zomera.
S-abscisic acid angagwiritsidwe ntchito kuthandiza mbewu kukana kutentha kochepa komanso kuzizira kozizira koyambirira kwa masika ndi kulima mbewu zatsopano zolimbana ndi kuzizira kwambiri.
4. S-abscisic acid imatha kusintha kukana chilala komanso kulolerana kwa mchere wa mchere wa zomera.
S-abscisic acid ili ndi phindu lalikulu kwambiri pothandiza anthu kuthana ndi chilala chochulukirachulukira, kupanga ndikugwiritsa ntchito minda yokolola yapakatikati ndi yotsika, komanso kulima nkhalango.
5. S-abscisic acid ndi cholepheretsa kukula kwamphamvu.
S-abscisic acid imatha kulepheretsa kukula kwa mbewu zonse kapena ziwalo zakutali. Zotsatira za ABA pakukula kwa zomera ndizosiyana ndi za IAA, GA, ndi CTK, ndipo zimalepheretsa kugawanika kwa maselo ndi kutalika. Kuletsa elongation ndi kukula kwa ziwalo monga mphukira sheaths, nthambi, mizu, ndi hypocotyls.
6. Kugwiritsa ntchito S-abscisic acid m'maluwa amaluwa
Popeza S-abscisic acid (ABA) imatha kutseka mwachangu pores zazikulu zamasamba, imatha kugwiritsidwa ntchito kusunga maluwa, kukulitsa nthawi yamaluwa (mfundo yoteteza maluwa), kuwongolera nthawi yamaluwa, komanso kulimbikitsa mizu (horticultural regulation).
Momwe mungagwiritsire ntchito S-abscisic acid kuphatikiza
1. S-abscisic acid + auxin
Makamaka kulimbikitsa rooting ndi mmera retardation pambuyo Thirani mbande, kapena mmera cuttings, etc.
2. Ethylhexyl + S-abscisic acid, S-abscisic acid + gibberellin
Ntchito yake ndikuwongolera kukula kwamphamvu ndikuwonjezera kuchuluka kwa zipatso.
3. Anti-agonist + S-abscisic acid
Wonjezerani kuyamwa kwa michere, kulimbikitsa kukula kwa mbande, kuonjezera kuchuluka kwa zinthu zowuma, ndikuwongolera kuzizira, kukana chilala, kukana matenda, ndi kukana tizilombo.
Idapezeka cha m'ma 1960 ndipo idatchulidwa molakwika chifukwa idakhudzana ndi kugwa kwamasamba. Komabe, tsopano zikudziwika kuti kugwa kwa masamba a zomera ndi zipatso kumayambitsidwa ndi ethylene.
S-abscisic acid ndi wobiriwira wobiriwira,S-abscisic acid ndi chomera chachilengedwe chogwira ntchito.
Zinthu zachilengedwezi zimapezeka kwambiri muzomera. Mwachilengedwe amakhala mu zipatso, ndiwo zamasamba ndi mbewu zomwe anthu amadya ndipo ndizotetezeka kwa anthu komanso chilengedwe.
Zopangira zomwe zimagwiritsidwa ntchito popanga ukadaulo wa abscisic acid ndizopanda poizoni komanso zopanda vuto zaulimi komanso zam'mbali. Imapezedwa kudzera mu nayonso mphamvu ya tizilombo tating'onoting'ono, popanda kuwonjezera zinthu zovulaza kapena zinthu, ndipo palibe zinthu zapoizoni pamapangidwe ake.

6. Kugwiritsa ntchito S-abscisic acid m'maluwa amaluwa
Popeza S-abscisic acid (ABA) imatha kutseka mwachangu pores zazikulu zamasamba, imatha kugwiritsidwa ntchito kusunga maluwa, kukulitsa nthawi yamaluwa (mfundo yoteteza maluwa), kuwongolera nthawi yamaluwa, komanso kulimbikitsa mizu (horticultural regulation).
