Cov khoom lag luam seaweed muaj kev txhawb nqa kev loj hlob, thiab kev siv cov qauv seaweed raws li biostimulants tau loj hlob hauv cov qoob loo ntau lawm. Biostimulants txhais tau tias yog" cov khoom uas txhawb kev loj hlob ntawm cov qoob loo ntxiv rau cov chiv." Thaum siv me me, cov nroj tsuag yuav loj hlob thiab hu ua" metabolism enhancers." Seaweed extract yog lom lom ntawm qhov tsis tshua muaj siab (diluted rau 1: 1000 lossis ntau dua).
Kev loj hlob hormone
Nws tau raug kuaj pom tias seaweed extract muaj cov nroj tsuag kev loj hlob regulators. Cov mis nyuj tshiab seaweed muaj cytokinin thiab indole acetic acid (IAA) gibberellin, cell division, thiab polyphenol compounds. Hauv cov nroj tsuag siab dua, IAA tshwm Nrog cov pab pawg carboxyl, glycans, amino acids, thiab peptides hloov mus rau IAA dawb tom qab hydrolysis.
Betaine
Raws li kev sib haum xeeb hauv cov nroj tsuag, betaine relieves osmotic stress induced by ntsev stress and drought stress. Lwm cov haujlwm kuj tau raug npaj, xws li txhim kho nplooj ntoos chlorophyll. Kuj tseem muaj pov thawj tias betaine tuaj yeem siv los ua ib qhov chaw ntawm nitrogen ntawm qhov tsis tshua muaj siab thiab siv los ua cov tshuaj osmotic ntau dua.
Sterol
Feem ntau, cov hlwb cog muaj cov sib tov ntawm sterols, xws listigmasterol,24-methylcholesterol thiab cholesterol. Brown seaweed mas muaj phycosterol thiab phycosterol derivatives, thaum liab seaweed mas muaj cov roj cholesterol thiab cov roj cholesterol derivatives. Ntsuab seaweed feem ntau khaws ergosterol thiab 24-methyl echo cholesterol.
