Salicylic acid na-arụ ọrụ dị iche iche n'ọrụ ugbo, gụnyere ịbụ ihe na-achịkwa uto osisi, ọgwụ ahụhụ, na ọgwụ nje.
Asịd salicylic, dịkaihe na-achịkwa uto osisi,na-arụ ọrụ dị mkpa n'ịkwalite uto osisi na ịbawanye ihe ubi. Ọ nwere ike ime ka mmepụta nke homonụ dị n'ime osisi dịkwuo mma, mee ka uto na ọdịiche ha dịkwuo ngwa ngwa, ma nyere osisi aka ime mgbanwe gburugburu ebe obibi. Salicylic acid nwekwara ike igbochi ogologo nke nsọtụ osisi nke ọma, na-eme ka osisi sie ike ma belata ọrịa na nje. E wezụga ịbụ ihe na-achịkwa uto osisi, a pụkwara iji salicylic acid dị ka ọgwụ ahụhụ. N'ọhịa ọrụ ugbo, ihe atụ ndị a na-ahụkarị gụnyere acetylsalicylic acid na sodium salicylate. Kemịkalụ ndị a nwere ike igbu ahụhụ na ọrịa ndị na-emebi osisi nke ọma, na-echebe uto nke ihe ubi. N'ọhịa ahụike, salicylic acid bụkwa ọgwụ a na-ejikarị egbochi ọrịa. N'ọhịa ọrụ ugbo, a na-eji salicylic acid egbochi ọrịa na-efe efe na anụmanụ. N'otu oge ahụ, salicylic acid nwere ike ime ka iguzogide ọrịa na oge nchekwa nke ngwaahịa ugbo dịkwuo mma.
Salicylic Acid (nke a kpọrọ SA) abụghị ọgwụ nje ọdịnala (dịka ọgwụ ahụhụ, ọgwụ nje, ma ọ bụ ọgwụ ahịhịa) n'ọrụ ugbo. Agbanyeghị, ọ na-arụ ọrụ dị oke mkpa na usoro nchekwa osisi na nhazi nke iguzogide nrụgide. N'afọ ndị na-adịbeghị anya, a mụọla ma tinye salicylic acid n'ọrụ ugbo dị ka ihe na-akpali ihe mgbochi osisi ma ọ bụ ihe na-akpali ihe ndị dị ndụ, ọ nwekwara ọrụ ndị a:
1. Mmelite nke iguzogide sistemụ osisi (SAR)
Salicylic acid bụ molekul na-egosi ihe ndị sitere n'okike n'ime osisi, nke na-agbakọta ngwa ngwa mgbe ọrịa nje butere.
Ọ nwere ike ime ka usoro iguzogide ihe ndị a na-enweta n'ime ahụ (SAR) rụọ ọrụ, na-eme ka osisi ahụ dum nwee ike iguzogide ọtụtụ nje dị iche iche (karịsịa fungi, bacteria, na virus).
2. Mee ka osisi na-anabata nrụgide na-abụghị nke ihe ndị dị ndụ dịkwuo mma
Salicylic acid nwere ike ime ka osisi ghara ịnagide nrụgide ndị na-abụghị nke ndụ dịka ụkọ mmiri ozuzo, nnu, obere okpomọkụ, oke okpomọkụ, na mmetọ ígwè dị arọ.
Usoro ndị a gụnyere: ịchịkwa ọrụ nke enzymes antioxidant (dịka SOD, POD, CAT), ịnọgide na-enwe nkwụsi ike nke akpụkpọ ahụ sel, na ịkwalite mkpokọta nke ihe ndị na-achịkwa osmotic (dịka proline, shuga na-agbaze agbaze), wdg.
3. Ịhazi uto na mmepe osisi
Obere nchịkọta nke salicylic acid nwere ike ịkwalite mkpụrụ osisi, mmepe mgbọrọgwụ na photosynthesis.
Otú ọ dị, nnukwu mkpokọta nwere ike igbochi uto, na-egosi "mmetụta homonu biphasic" (mmetụta hormesis).
4. Dịka akụkụ nke atụmatụ njikwa akwụkwọ ndụ akwụkwọ ndụ
Ọ bụ ezie na salicylic acid n'onwe ya enweghị ike igbu nje bacteria na-akpata ọrịa ozugbo, ọ nwere ike ibelata ojiji nke ọgwụ nje site n'ịkpalite usoro nchekwa nke osisi ahụ.
A na-ejikarị ya eme ihe na ihe ndị ọzọ dị ndụ (dịka chitosan, jasmonic acid) iji mee ka arụmọrụ ya ka mma.
Fọm ngwa n'ezie
Ịgba akwụkwọ: Ọnụọgụ a na-ahụkarị bụ 0.1–1.0 mM (ihe dị ka 14–140 mg/L), nke enwere ike ịgbanwe dịka ụdị ihe ọkụkụ na ebumnuche ya si dị.
Ọgwụgwọ mkpụrụ: Ịmikpu mkpụrụ iji mee ka ọrịa ghara iguzogide ya ma mee ka ọ pụta ìhè.
Ịgwakọta ya na ọgwụ nje: Ime ka ihe ọkụkụ ghara iguzogide ọrịa dị iche iche ma mee ka ọgwụ nje ahụ dịkwuo irè.
Ihe ndetu maka nlebara anya
Oke ntinye uche nwere ike ibute nsị phytotoxicity (dịka ọkụ akwụkwọ na igbochi uto).
Mmetụta ya na-adabere n'ọnọdụ gburugburu ebe obibi (okpomọkụ, iru mmiri), ụdị ihe ọkụkụ na oge e ji mee ihe.
Ugbu a, a kabeghị aha salicylic acid dị ka ọgwụ nje na Chaịna na ọtụtụ mba ndị ọzọ. A na-ejikarị ya eme ihe dị ka ihe na-achịkwa uto osisi ma ọ bụ ihe na-akpali ihe ndị dị ndụ.
Nchịkọta
Isi uru nke salicylic acid n'ọrụ ugbo dị na "ichebe osisi site na osisi" - site n'ịgbalite usoro ahụ ji alụso ọrịa ọgụ nke osisi ahụ iji guzogide ọrịa na ọnọdụ ọjọọ. Ọ bụ ihe bara uru nke kwekọrọ na echiche nke ọrụ ugbo akwụkwọ ndụ akwụkwọ ndụ na mmepe na-adịgide adịgide. Ọ bụ ezie na ọ bụghị ọgwụ nje ọdịnala, o nwere nnukwu ikike na njikwa nje agbakwunyere (IPM).
