Salicylic acid na-arụ ọtụtụ ọrụ na ọrụ ugbo, gụnyere ịbụ onye na-ahụ maka uto osisi, ọgwụ ụmụ ahụhụ, na ọgwụ nje.
Salicylic acid, dị ka aonye na-ahụ maka uto osisi,na-ekere òkè dị ukwuu n'ịkwalite uto ihe ọkụkụ na ịba ụba ihe ọkụkụ. Ọ nwere ike ịkwalite njikọ nke homonụ n'ime osisi, mee ka uto ha dịkwuo elu na ọdịiche dị iche iche, ma na-enyere osisi aka ime mgbanwe maka mgbanwe gburugburu ebe obibi. Salicylic acid nwekwara ike igbochi elongation nke ndụmọdụ osisi, na-eme ka osisi sie ike na ibelata ihe omume nke ọrịa na pests. E wezụga ịbụ onye na-achịkwa uto osisi, a pụkwara iji salicylic acid mee ihe dị ka ọgwụ ahụhụ. N'ebe ọrụ ugbo, ihe atụ a na-ahụkarị gụnyere acetylsalicylic acid na sodium salicylate. Kemịkalụ ndị a nwere ike igbu ụmụ ahụhụ na ọrịa na-efe efe na osisi, na-echebe uto nke ihe ọkụkụ. N'ihe gbasara ahụike, salicylic acid bụkwa ọgwụ na-egbochi ọrịa. N'ubi ugbo, a na-eji salicylic acid egbochi ọrịa na-efe efe na anụmanụ. N'otu oge ahụ, salicylic acid nwere ike ịkwalite nguzogide ọrịa na oge nchekwa nke ngwaahịa ugbo.
Salicylic acid (nke a na-akpọ SA) abụghị ọgwụ pesticide ọdịnala (dị ka ọgwụ ahụhụ, fungicides, ma ọ bụ ahịhịa) n'ọrụ ugbo. Agbanyeghị, ọ na-arụ ọrụ dị oke mkpa na usoro nchekwa ihe ọkụkụ na nhazi nke nguzogide nrụgide. N'ime afọ ndị na-adịbeghị anya, a mụọla salicylic acid nke ọma ma tinye ya n'ọrụ n'ọrụ ugbo dị ka ihe ọkụkụ na-alụso ọrịa ọgụ ma ọ bụ ihe na-akpali akpali, na ọ nwere ọrụ ndị a:
1. ịgbalite ihe ọkụkụ sistemu enwetara nguzogide (SAR)
Salicylic acid bụ mkpụrụ ndụ ihe na-egosi n'okike n'ime osisi, nke na-agbakọta ngwa ngwa mgbe ọrịa nje gasịrị.
Ọ nwere ike ịgbalite nguzogide sistemu enwetara (SAR), na-eme ka osisi ahụ dum nwee ike imegide ụdị ọrịa dị iche iche (karịsịa fungi, nje bacteria na nje).
2. welie nnabata nke osisi na-abụghị ndu nchegbu
Salicylic acid nwere ike ịkwalite nnabata nke osisi na nrụgide na-abụghị nke ndu dị ka ụkọ mmiri ozuzo, salinity, obere okpomọkụ, okpomọkụ dị elu, na mmetọ ígwè dị arọ.
Usoro gụnyere: ịchịkwa ọrụ nke enzymes antioxidant (dị ka SOD, POD, CAT), na-edobe nkwụsi ike nke membranes cell, na ịkwalite mkpokọta ihe nchịkwa osmotic (dị ka proline, soluble sugars), wdg.
3. Na-achịkwa uto na mmepe osisi
Mmetụta dị ala nke salicylic acid nwere ike ịkwalite mpụta mkpụrụ, mmepe mgbọrọgwụ na photosynthesis.
Otú ọ dị, ọnụ ọgụgụ dị elu nwere ike igbochi uto, na-egosipụta "mmetụta biphasic hormone" (mmetụta hormesis).
4. Dị ka akụkụ nke usoro njikwa akwụkwọ ndụ akwụkwọ ndụ
Ọ bụ ezie na salicylic acid n'onwe ya enweghị ikike igbu nje bacteria na-akpata ozugbo, ọ nwere ike ibelata ojiji nke ọgwụ pesticides na-egbu egbu site n'ịkwalite usoro nchebe nke osisi ahụ.
A na-ejikarị ya na ihe ndị ọzọ dị ndụ (dị ka chitosan, jasmonic acid) iji mee ka ọ dịkwuo mma.

Nchịkọta
Isi uru nke salicylic acid na ọrụ ugbo bụ "ichekwa osisi site na osisi" - site n'ịgbalite usoro mgbochi nke osisi ahụ iji guzogide ọrịa na ọnọdụ ọjọọ.
