S-Abscisic Acid (ABA) Ntchito ndi zotsatira zogwiritsira ntchito
1.Kodi S-Abscisic Acid(ABA) ndi chiyani?
S-Abscisic Acid (ABA) ndi hormone ya zomera. S-Abscisic Acid ndiwowongolera kukula kwa zomera zomwe zimatha kulimbikitsa kukula kwa zomera, kupititsa patsogolo kukula kwa zomera, ndikulimbikitsa kukhetsa masamba. Popanga zaulimi, Abscisic Acid imagwiritsidwa ntchito makamaka kuyambitsa kukana kwa mbewuyo kapena kusinthira kumavuto, monga kukonza kukana chilala kwa mbewu, kukana kuzizira, kukana matenda, komanso kukana mchere wamchere.
2.Mechanism of action of S-Abscisic Acid
S-Abscisic Acid imapezeka kwambiri muzomera, ndipo pamodzi ndi gibberellins, auxins, cytokinins, ndi ethylene, imapanga mahomoni asanu akuluakulu amtundu wa zomera. Itha kugwiritsidwa ntchito kwambiri mu mbewu monga mpunga, masamba, maluwa, udzu, thonje, mankhwala azitsamba aku China, ndi mitengo yazipatso kuti ipititse patsogolo kukula kwamphamvu komanso kuchuluka kwa fruiting ndi mtundu wa mbewu m'malo owopsa monga kutentha, chilala, masika. ozizira, salinization, tizirombo ndi matenda, amachulukitsa zokolola pagawo lililonse la minda yapakatikati komanso yotsika, ndikuchepetsa kugwiritsa ntchito mankhwala ophera tizilombo.
3. Kugwiritsa ntchito kwa S-Abscisic Acid muulimi
(1) S-Abscisic Acid imathandizira kukana kupsinjika kwa abiotic
Pazaulimi, mbewu nthawi zambiri zimakumana ndi mavuto abiotic (monga chilala, kutentha pang'ono, mchere, kuwonongeka kwa mankhwala ophera tizilombo, etc.).
Pansi pa chilala chadzidzidzi, kugwiritsa ntchito S-Abscisic Acid kumatha kuyambitsa ma cell conduction pa plasma nembanemba ya maselo a masamba, kupangitsa kutsekedwa kosagwirizana kwa tsamba la stomata, kuchepetsa kutuluka ndi kutayika kwa madzi m'thupi la mbewu, ndikukulitsa mphamvu yosungira madzi ya mbewuyo. kulekerera chilala.
Pansi pa kutentha kochepa, kugwiritsa ntchito S-Abscisic Acid kungayambitse majini olimbana ndi kuzizira kwa maselo ndikulimbikitsa zomera kuti zipange mapuloteni oletsa kuzizira.
Pansi pa kugwa kwa mchere wa dothi, S-Abscisic Acid ingapangitse kuchuluka kwakukulu kwa proline, chinthu cha osmotic regulating mu zomera, kusunga kukhazikika kwa ma cell membrane, ndikuwonjezera ntchito ya ma enzyme oteteza. Chepetsani kuchuluka kwa Na+ pagawo lililonse kulemera kwa chinthu chowuma, onjezerani zochita za carboxylase, ndikukulitsa kulolerana kwa mchere kwa zomera.
Pansi pa kupsinjika kwa mankhwala ophera tizilombo ndi kuwonongeka kwa feteleza, S-Abscisic Acid imatha kuwongolera kuchuluka kwa mahomoni amkati muzomera, kuyimitsa kuyamwa kwina, ndikuchotsa bwino zotsatira zoyipa za kuwonongeka kwa mankhwala ophera tizilombo ndi feteleza. Ikhozanso kupititsa patsogolo mgwirizano ndi kudzikundikira kwa anthocyanins ndikulimbikitsa mitundu ya mbewu ndi kukhwima koyambirira.
2) S-Abscisic Acid imakulitsa kukana kwa mbewu ku tizilombo toyambitsa matenda
Kupezeka kwa tizirombo ndi matenda ndizosapeweka panthawi ya kukula kwa zomera. Pansi pa kupsinjika kwa matenda, S-Abscisic Acid imapangitsa kuti ma jini a PIN ayambike m'maselo amasamba kuti apange mapuloteni a enzyme inhibitors (flavonoids, quinones, etc.), omwe amalepheretsa kuwonjezereka kwa tizilombo toyambitsa matenda, kupewa kuwonongeka kapena kuchepetsa kuchuluka kwa kuwonongeka. ku zomera.
(3) S-Abscisic Acid imalimbikitsa kusintha kwa mtundu ndi kukoma kwa zipatso
S-Abscisic Acid imakhala ndi zotsatira za kusintha kwamtundu koyambirira komanso kutsekemera kwa zipatso monga mphesa, malalanje, ndi maapulo.
(4) S-Abscisic Acid ikhoza kuonjezera chiwerengero cha mizu yotsatizana ndi mizu ya mbewu.
Kwa mbewu monga thonje, S-Abscisic Acid ndi feteleza monga humic acid amadonthetsedwa m’madzi, ndipo mbande zimatuluka ndi madzi odontha. Ikhoza kuonjezera chiwerengero cha mizu yofananira ndi mizu yoyambira ya mbande za thonje pamlingo wina, koma sizodziwikiratu m'minda ya thonje yokhala ndi mchere wambiri.
(5) S-Abscisic Acid imasakanizidwa ndi feteleza kuti azitha kulimbitsa thupi komanso kuchita nawo gawo lina pakuchepetsa thupi.
4. Ntchito zogwiritsira ntchito S-Abscisic Acid
Chomera "growth balance factor"
Kulimbikitsa kukula kwa mizu ndikulimbikitsa mizu, kulimbikitsa kukula kwa mizu ya capillary; kulimbikitsa kukula kwa mbande zolimba ndikuwonjezera zokolola; kulimbikitsa kumera ndi kusunga maluwa, kuwonjezera kuchuluka kwa zipatso; kulimbikitsa mtundu wa zipatso, kukolola koyambirira, ndikuwongolera bwino; kumawonjezera kuyamwa kwa michere ndikuwonjezera kuchuluka kwa magwiritsidwe ntchito a feteleza; pawiri ndi kuonjezera mphamvu, ndi kuchepetsa wamba mankhwala zoipa zotsatira monga zipatso kupunduka, maenje, ndi losweka zipatso.
Chomera "resistance induction factor"
Kulimbikitsa kukana matenda a mbewu ndikuthandizira kukana matenda; onjezerani kukana kwa mbewu ku zovuta (kukana kuzizira, kukana chilala, kukana madzi, kukana mchere ndi alkali, etc.); kuchepetsa ndi kuchepetsa kuwonongeka kwa mankhwala a mbewu.
Zobiriwira komanso zachilengedwe
S-Abscisic Acid ndi zinthu zachilengedwe zoyera zomwe zili muzomera zonse zobiriwira, zomwe zimapezeka makamaka kudzera mu kupesa kwa tizilombo tating'onoting'ono, topanda poizoni komanso osakwiyitsa anthu ndi nyama. Ndi mtundu watsopano wa zomera zobiriwira zomwe zimagwira ntchito bwino, zomwe zimakonda kugwiritsidwa ntchito.
5. Kuchuluka kwa S-Abscisic Acid
Amagwiritsidwa ntchito makamaka mu mpunga, tirigu, mbewu zina zazikulu za chakudya, mphesa, tomato, citrus, fodya, mtedza, thonje ndi masamba ena, mitengo ya zipatso ndi mbewu zamafuta. Zimagwira ntchito yofunika kwambiri pakuwongolera kukula, kulimbikitsa mizu ndi kulimbikitsa mitundu.
