5-aminolevulinic acid (5-ALA lossis ALA luv luv), molecular mis C5H9N03. Nws yog ib qho tseem ceeb precursor rau biosynthesis ntawm tetrapyrrole tebchaw xws li heme, chlorophyll, thiab vitamin B12, thiab yog ib qho tseem ceeb rau cov nroj tsuag photosynthesis thiab cellular zog metabolism cuam tshuam. Los ntawm kev siv ALA cov khoom, cov ntsiab lus chlorophyll hauv cov nroj tsuag chloroplasts tuaj yeem ua tau zoo. Vim tias ALA yog qhov yuav tsum tau ua ua ntej rau chlorophyll biosynthesis. Nws tuaj yeem tswj cov synthesis ntawm chlorophyll los txhim kho photosynthetic efficiency thiab ua pa ua pa, thiab tsim cov suab thaj ntau, enzymes thiab lub zog rau cov nroj tsuag loj hlob.
● Txhawb chlorophyll synthesis
Nrog rau qhov nce ntawm chlorophyll, cov xim ntsuab ntawm nplooj yuav tsaus, lub peev xwm photosynthesis yog txhim kho, thiab qhov tshwm sim ntawm nplooj yellowing thiab defo-liation yog tiv thaiv.
● lmprove photosynthesis thiab inhibit ua pa tsaus
Los ntawm kev nce cov ntsiab lus ntawm chlorophyll, nws tuaj yeem txhawb cov nroj tsuag kev loj hlob, txhim kho cov qoob loo thiab zoo, thiab nce cov ntsiab lus qab zib. Nws kuj tswj cov pa roj carbon assimilation, pho-tosynthase kev ua haujlwm thiab lub plab qhib.
● Txhim kho kev ua siab ntev ntawm ib puag ncig kev ntxhov siab
Txhim kho lub peev xwm ntawm cov qoob loo kom tiv taus ib puag ncig hnyav. Qhov phem tshaj qhov cultiva-tion tej yam kev mob, qhov pom tseeb cov nyhuv. Cov khoom lag luam kuj tseem siv tau rau cov teb uas yuav raug ntsev puas tsuaj vim muaj ntau tshaj fertilization. Thaum siv 5-AL A, polysaccharides (fructans, thiab lwm yam) yuav sib sau ua ke hauv nplooj thiab cov hauv paus hniav thiab nce osmotic siab los txhim kho lub peev xwm ntawm cov qoob loo kom tiv thaiv lub teeb tsis txaus, txias, salinity, thiab lwm yam.
● lmprove cov haujlwm ntawm nitrate reductase
Nws txhim kho lub peev xwm ntawm cov nroj tsuag kom txo tau cov nitrate thiab cov ntsiab lus ntawm antioxidant enzymes, thiab ua rau kom nqus tau thiab uilizaticn ntawm nitrogen thiab mineral ele-ments los ntawm cov nroj tsuag.
● Ua kom cov ntsiab lus qhuav ntawm cov yub
● Inhibits leggy thiab tsis muaj zog kev loj hlob tshwm sim los ntawm ntau heev daim ntawv thov nitrogen los yog insufi-cient teeb nyob rau hauv seedlings.
Cov khoom no yog me ntsis acidic kua. Thov tsis txhob sib xyaw nrog calcium thiab cov khoom uas muaj pH siab dua 7.
