Chitosan oligosaccharide
Lebitso la saense la chitosan oligosaccharide ke B-1,4-oligosaccharide glucosamine, Ke sehlahisoa sa oligosaccharide se fumanoang ka ho senya chitosan, ke enzyme e khethehileng ea biological technolo-gy. Boima ba limolek'hule s3000Da, ho qhibiliha ha metsi hantle, ts'ebetso e kholo le sehlahisoa se tlaase sa boima ba limolek'hule se nang le ts'ebetso e phahameng ea likokoana-hloko.
E na le solubility e phahameng eo chitosan e se nang eona, 'me e qhibiliha ka ho feletseng metsing.E na le mesebetsi e mengata e ikhethang e kang ho kenngoa habonolo le ho sebelisoa ke lintho tse phelang, phello ea eona ke makhetlo a 14 ho feta a chitosan.Chitosan oligosaccharide ke eona feela e qosoang hantle. cationic basic amino oligosaccharide tlhahong mme ke selulose ea liphoofolo.
1.Ntlafatsa tikoloho ea mobu
Chitosan oligosaccharide e ka sebelisoa e le fungicide e susumetsang ho fetola limela tsa mobu le ho khothalletsa kholo ea likokoana-hloko tse molemo. Chitosan oligosaccharide e ka boela ea baka ho hanyetsa maloetse a limela, 'me ea ba le liphello tsa ho itšireletsa mafung le ho bolaea mefuta e mengata ea li-fungus, badteria le likokoana-hloko. Ho ikatisa ka bongata ha likokoana-hloko ho ka khothaletsa sebopeho sa mobu o kopaneng, ho ntlafatsa thepa ea 'mele le ea lik'hemik'hale mobung, ho matlafatsa pemeability le bokhoni ba ho boloka metsi le ferilizer; kahoo ho fana ka tikoloho e ntle ea tikoloho ea mobu bakeng sa tsamaiso ea metso, e le hore limatlafatsi tse fapa-fapaneng mobung li kenngoe hantle ka makhetlo a mahlano.
2.Iduce limela ho hanyetsa le ho hanyetsa khatello ea kelello
Chitosan oligosaccharide, e le moemeli oa khanyetso ea lijalo, e ka susumetsa ka katleho ho hanyetsa mafu a limela, ho ntlafatsa ts'ireletso ea semela khahlanong le mafu, ho hanela serame, mocheso o phahameng oa mocheso, komello le ho phalla ha metsi, letsoai, tšenyo ea manyolo, tšenyo ea moea, ho hanyetsa ho se leka-lekane ha phepo e nepahetseng. Ho thehoa ha lignin Lignin ke karolo e ka sehloohong ea lerako la bobeli la lisele tsa methapo ea limela, eo ka boeona e hanyetsanang le ho senyeha ha likokoana-hloko. Chitosan oligosaccharide e ka etsa hore ho be le lignification ho potoloha ntlha e tšoaelitsoeng ea limela, ea etsa tšitiso ea 'mele, ka hona ea thibela kapa ea liehisa ho hola le ho ata ha likokoana-hloko ho lisele tse potolohileng li-nomal, le ho ntlafatsa ho hanyetsa lefu la limela.
3. E ka sebelisoa e le moemeli oa ho roala peo, ho roala peo
Litaolo tsa kholo ea limela le li-antibacterial agents li ka etsa hore limela li hlahise liprotheine tsa PR (mofuta oa protheine e hlahisoang ke limela tse hlohlelletsoang le ho hatelloa ke likokoana-hloko kapa lintho tse ling) le phytochemicals, ho sebelisa li-amino oligosaccharides e le likarolo tsa motheo tsa ho aba menontsha ea lik'hemik'hale, Nts'etsopele ea ho roala peo e ncha. mahlahana a nang le trace elements.
4.Plant manyolo a sebetsang
Chitosan oligosaccharide e kopana le li-cell membrane receptors, e fetisetsa lipontšo tsa motlakase, e kenya tšebetsong mekhoa e fapaneng ea 'mele ea ho itšireletsa mafung, e tenya lerako la lisele, e eketsa li-substano tse fapaneng tse hanyetsanang le metsoako e sebetsang liseleng,' me e hlohlelletsa lijalo ho ntlafatsa khanyetso le ho holisa kholo. phello ea Chitosan oligo-saccharides e sebelisoa hammoho le limatlafatsi tse fumanoeng ho finyella liphello tse ntle ka ho fetisisa.
