Chitosan Oligosaccharides
Magaca sayniska ee chitosan oligosaccharide waa B-1,4-oligosaccharide glucosamine, Waa shey oligosaccharide ah oo lagu helay hoos u dhigista chitosan, by teknolojiyada enzyme bayooloji gaar ah. Miisaanka molecular s3000Da, biyo wanaagsan oo milmay, shaqo weyn iyo badeecad miisaankeedu hooseeyo oo leh hawl bayooloji sare leh.
Waxay leedahay solubility sare oo aan chitosan lahayn, oo si buuxda ugu milmay biyaha.Waxay leedahay hawlo badan oo gaar ah sida in si fudud loo nuugo oo laga faa'iidaysto noolaha, Saameynteedu waa 14 jeer ka mid ah chitosan. cationic amino oligosaccharides ee dabiiciga ah iyo waa cellulose xayawaanka.
1.lprove deegaanka ciidda
Chitosan oligosaccharides waxaa loo isticmaali karaa kicinta fungicides si loo beddelo flora ciidda oo kor loogu qaado korriinka microorganisms faa'iido leh. Chitosan oligosaccharides waxay sidoo kale keeni kartaa iska caabbinta cudurada dhirta, waxayna leedahay difaac iyo saameyn ku yeelashada fangaska, badteria iyo fayrasyada kala duwan. Taranka mass ee microorganisms kor u qaadi kara fomation ee qaab-dhismeedka wadareedka ciidda, hagaajinta sifooyinka jirka iyo kiimikaad ee ciidda, enhanoe pemeability iyo awoodda ay u leeyihiin in ay biyo iyo bacrimiyad; sidaas darteed siinta jawi wanaagsan oo micro-ecological ciidda nidaamka xididka, si nafaqooyinka kala duwan ee carrada ay si wax ku ool ah-shan firfircoon u shaqeeyaan.
2.Induce adkeysiga cudurada dhirta iyo iska caabin stress
Chitosan oligosaccharides, sida wakiilka iska caabinta dalagyada, waxay si wax ku ool ah u dhalin kartaa iska caabbinta cudurada dhirta, waxay wanaajisaa awooda difaaca dhirta ee cudurada, iska caabida qabowga, heerkulka sare, abaarta iyo cirridka biyaha, salinity, waxyeelada bacriminta, waxyeelada hawada, iska caabinta dheelitir la'aanta Nafaqada. Samaynta lignin ee la kiciyay Lignin waa qaybta ugu muhiimsan ee gidaarka unugyada labaad ee unugyada xididada xididada dhirta, kaas oo laftiisu u adkaysta xaalufka microbial. Chitosan oligosaccharides waxay keeni kartaa lignification agagaarka barta cudurka qaba ee dhirta, samaynta xannibaad jireed, taas oo ka hortagaysa ama dib u dhigista korriinka iyo faafinta cudur-sidaha unugyada ku hareeraysan unugyada caadiga ah, iyo kor u qaadida cudurka resistanoe ee dhirta.
3. Waxa loo isticmaali karaa sida wakiilka dahaarka abuur, wakiilka dhaymada abuur
Xakamaynta koritaanka dhirta iyo wakiilada bakteeriyada waxay keeni karaan dhirta si ay u soo saaraan borotiinka PR (nooc ka mid ah borotiinka ay soo saaraan dhirta ay kiciyaan oo ay ku adkeeyaan cudurada ama arrimo kale) iyo phytochemicals, iyagoo isticmaalaya amino oligosaccharides sida qaybaha aasaasiga ah si loo qaybiyo bacrimiyeyaasha kiimikada, Horumarinta abuur cusub wakiilada leh walxaha raadraaca.
4.Bacriminta dhirta ee shaqaynaysa
Chitosan oligosaccharides waxay ku daraysaa xuubka unugyada, waxay gudbisaa calaamadaha korantada, waxay kicisaa dariiqyada difaaca ee kala duwan, waxay adkeyneysaa derbiga unugyada, waxay kordhisaa noocyo kala duwan oo substanoes ah iyo walxo firfircoon oo ku jira unugyada, waxayna kicisaa dalagyada si ay u hagaajiyaan caabbinta waxayna kor u qaadaan koritaanka. saamaynta Chitosan oligo-saccharides waxaa loo isticmaalaa in lagu daro nafaqooyinka la helay si loo gaaro natiijooyinka ugu fiican.
