I-S-Abscisic Acid (ABA) Imisebenzi kanye nomphumela wesicelo
1.yini i-S-Abscisic Acid(ABA)?
I-S-Abscisic Acid (ABA) iyi-hormone yesitshalo. I-S-Abscisic Acid isilawuli sokukhula kwezitshalo esingokwemvelo esingakhuthaza ukukhula kwezitshalo okudidiyelwe, sithuthukise ikhwalithi yokukhula kwezitshalo, futhi sikhuthaze ukuchitheka kwamaqabunga ezitshalo. Emkhiqizweni wezolimo, i-Abscisic Acid isetshenziswa kakhulu ukwenza ukuthi isitshalo simelane noma sijwayelane nobunzima, njengokuthuthukisa ukumelana nesomiso kwesitshalo, ukumelana nokubanda, ukumelana nezifo, kanye nokumelana nosawoti-alkali.
2.Indlela yokwenza ye-S-Abscisic Acid
I-S-Abscisic Acid itholakala kabanzi ezitshalweni, futhi kanye nama-gibberellins, ama-auxins, ama-cytokinins, ne-ethylene, yakha amahomoni amahlanu amakhulu esitshalo. Ingasetshenziswa kabanzi ezitshalweni ezifana nelayisi, imifino, izimbali, utshani, ukotini, imithi ye-herbal yamaShayina, nezihlahla zezithelo ukuthuthukisa amandla okukhula kanye nezinga lezithelo kanye nekhwalithi yezitshalo ezindaweni ezikhulayo ezingezinhle ezifana nezinga lokushisa eliphansi, isomiso, intwasahlobo. amakhaza, ukufakwa kukasawoti emanzini, izinambuzane nezifo, kwenyusa isivuno endaweni ngayinye yamasimu anesivuno esimaphakathi nesiphansi, futhi kunciphise ukusetshenziswa kwezibulala-zinambuzane zamakhemikhali.
3. Umphumela wokusetshenziswa kwe-S-Abscisic Acid kwezolimo
(1) I-S-Abscisic Acid ithuthukisa ukumelana nokucindezeleka kwe-abiotic
Ekukhiqizweni kwezolimo, izitshalo zivame ukuba ngaphansi kwengcindezi ye-abiotic (njengesomiso, izinga lokushisa eliphansi, usawoti, ukulimala kwezibulala-zinambuzane, njll.).
Ngaphansi kwengcindezi yesomiso engazelelwe, ukusetshenziswa kwe-S-Abscisic Acid kungenza kusebenze ukuqhutshwa kweseli kulwelwesi lwe-plasma lamangqamuzana amaqabunga, kubangele ukuvalwa okungalingani kwe-leaf stomata, kunciphise ukuphefumula nokulahlekelwa kwamanzi emzimbeni wesitshalo, futhi kuthuthukise amandla okugcina amanzi esitshalo futhi ukubekezelela isomiso.
Ngaphansi kokucindezelwa kwezinga lokushisa eliphansi, ukusetshenziswa kwe-S-Abscisic Acid kungenza izakhi zofuzo zokumelana nokubanda zisebenze futhi zenze izitshalo zikhiqize amaprotheni okumelana nokubanda.
Ngaphansi kwengcindezi yokugoqa kukasawoti enhlabathini, i-S-Abscisic Acid ingenza ukunqwabelana okukhulu kwe-proline, into elawula i-osmotic ezitshalweni, igcine ukuqina kwesakhiwo se-cell membrane, futhi yandise umsebenzi wama-enzyme okuvikela. Yehlisa okuqukethwe kwe-Na+ ngeyunithi ngayinye isisindo sento eyomile, khulisa umsebenzi we-carboxylase, futhi uthuthukise ukubekezelela usawoti wezitshalo.
Ngaphansi kwengcindezi yokulimala kwezinambuzane kanye nomanyolo, i-S-Abscisic Acid ingalawula ibhalansi yamahomoni angapheli ezitshalweni, imise ukumuncwa okwengeziwe, futhi iqede ngempumelelo imiphumela emibi yokulimala kwezinambuzane kanye nomanyolo. Ingase futhi ithuthukise ukubambisana nokunqwabelana kwama-anthocyanins futhi ikhuthaze umbala wezitshalo nokuvuthwa kwangaphambi kwesikhathi.
2) I-S-Abscisic Acid ithuthukisa ukumelana kwezitshalo kumagciwane
Ukuvela kwezinambuzane nezifo akunakugwenywa ngesikhathi sokukhula kwezitshalo. Ngaphansi kokucindezeleka kwezifo, i-S-Abscisic Acid yenza kusebenze izakhi zofuzo ze-PIN kumangqamuzana amaqabunga ezitshalo ukukhiqiza ama-protein enzyme inhibitors (ama-flavonoids, ama-quinones, njll.), okuvimbela ukuhlasela okuqhubekayo kwamagciwane, ukugwema ukulimala noma ukunciphisa izinga lomonakalo. ezitshalweni.
(3) I-S-Abscisic Acid ikhuthaza ukushintsha kombala kanye noshukela wezithelo
I-S-Abscisic Acid inomphumela wokushintsha umbala kwasekuqaleni kanye noshukela wezithelo ezifana namagilebhisi, amawolintshi, nama-apula.
(4) I-S-Abscisic Acid ingakhuphula inani lezimpande ezisemaceleni kanye nezimpande ezizayo zezitshalo
Ezitshalweni ezinjengokotini, i-S-Abscisic Acid kanye nomanyolo onjenge-humic acid ziconselwa emanzini, futhi izithombo ziphuma namanzi aconsayo. Ingakwazi ukwandisa inani lezimpande ze-lateral kanye nezimpande ze-adventitious zezithombo zikakotini ngezinga elithile, kodwa akubonakali emasimini kakotini ane-alkalinity ephezulu.
(5) I-S-Abscisic Acid ixutshwa nomanyolo ukuze kulinganiswe izakhi futhi idlale indima ethile ekunciphiseni isisindo.
4.Imisebenzi yokusetshenziswa kwe-S-Abscisic Acid
Isitshalo "i-growth balance factor"
Khuthaza ukukhula kwezimpande futhi uqinise izimpande, ukhuthaze ukukhula kwezimpande ze-capillary; khuthaza ukukhula kwezithombo ezinamandla futhi andise isivuno; khuthaza ukuhluma nokugcinwa kwezimbali, ukwandisa izinga lokumiswa kwezithelo; thuthukisa umbala wezithelo, ukuvunwa kwangaphambi kwesikhathi, futhi uthuthukise ikhwalithi; thuthukisa ukumuncwa kwezakhi futhi uthuthukise izinga lokusebenzisa umanyolo; ihlanganise futhi ikhulise ukusebenza kahle, futhi inciphise imiphumela emibi evamile yezidakamizwa njengokukhubazeka kwezithelo, izimbobo, nezithelo eziqhekekile.
Isitshalo "i-resistance induction factor"
Khulisa ukumelana nezifo zezitshalo futhi uthuthukise ukumelana nezifo; thuthukisa ukumelana nezitshalo ebunzimeni (ukumelana nokubanda, ukumelana nesomiso, ukumelana nokugcwala kwamanzi, ukumelana nosawoti kanye ne-alkali, njll.); nciphisa futhi unciphise ukulimala kwezidakamizwa zezitshalo.
Imikhiqizo eluhlaza kanye nemvelo
I-S-Abscisic Acid iwumkhiqizo wemvelo omsulwa oqukethwe kuzo zonke izitshalo eziluhlaza, ikakhulukazi etholakala ngokuvutshelwa kwe-microbial, engenabuthi futhi engacasuli abantu nezilwane. Iwuhlobo olusha lwesitshalo esisebenzayo esikhula kahle, esingokwemvelo esinamathemba okusebenza abanzi.
5. Ububanzi besicelo se-S-Abscisic Acid
Isetshenziswa kakhulu elayisi, ukolweni, ezinye izitshalo zokudla ezinkulu, amagilebhisi, utamatisi, amawolintshi, ugwayi, amakinati, ukotini neminye imifino, izihlahla zezithelo nezilimo zikawoyela. Idlala indima ebalulekile ekulawuleni ukukhula, ukukhuthaza ukumila kwezimpande kanye nokuthuthukisa umbala.
I-S-Abscisic Acid (ABA) iyi-hormone yesitshalo. I-S-Abscisic Acid isilawuli sokukhula kwezitshalo esingokwemvelo esingakhuthaza ukukhula kwezitshalo okudidiyelwe, sithuthukise ikhwalithi yokukhula kwezitshalo, futhi sikhuthaze ukuchitheka kwamaqabunga ezitshalo.
