| Khoom npe | 1-Methylcyclopropene |
| Toxicity | Tsawg toxicity, LD50> 5000mg / kg, raws li kev faib tawm toxicity, belongs rau cov tshuaj tsis muaj tshuaj lom. |
| Action mechanism | 1-MCP yog ib qho zoo heev inhibitor ntawm ethylene ntau lawm thiab ethylene ua. Raws li cov tshuaj hormones cog uas txhawb kev loj hlob thiab kev loj hlob, ethylene tuaj yeem tsim los ntawm qee cov nroj tsuag lawv tus kheej, thiab tuaj yeem muaj nyob rau hauv ib qho nyiaj hauv qhov chaw cia lossis txawm nyob hauv huab cua. Ethylene ua ke nrog cov receptors tseem ceeb hauv cov hlwb kom ua rau muaj kev cuam tshuam ntawm lub cev thiab biochemical cuam tshuam txog kev loj hlob, ua rau kev laus thiab kev tuag. l-MCP kuj tseem tuaj yeem ua ke zoo nrog cov ethylene receptors, tab sis qhov kev sib xyaw no yuav tsis ua rau cov tshuaj tiv thaiv biochemical, yog li ntawd, ua ntej tsim cov tshuaj endogenous ethylene hauv cov nroj tsuag lossis cov txiaj ntsig ntawm exogenous ethylene, daim ntawv thov ntawm 1-MCP, nws yuav yog tus ua ntej los ua ke nrog ethylene receptors, yog li tiv thaiv kev sib xyaw ntawm ethylene thiab nws cov receptors, ua kom lub sijhawm loj hlob ntawm cov txiv hmab txiv ntoo thiab zaub thiab txuas ntxiv mus. lub sijhawm tshiab. |
| Fuction | Siv los tsim ethylene los yog ethylene rhiab txiv hmab txiv ntoo thiab zaub, paj tshiab-kua. Nws tuaj yeem ncua kev loj hlob thiab kev laus zoo, tswj lub hardness thiab brittleness ntawm cov khoom zoo, tswj cov xim, tsw, ntxhiab thiab cov khoom noj muaj pes tsawg leeg, zoo tswj cov kab mob ntawm cov nroj tsuag, txo qhov lwj los ntawm cov kab mob thiab txo cov kab mob physiological, thiab txo cov dej evaporation thiab tiv thaiv wilting. Cov txiv hmab txiv ntoo thiab zaub hauv qab no, paj siv cov khoom siv kho mob no, lub txee lub neej ntev heev. Cov hauv qab no yog lub luag haujlwm ntawm 1-methylcyclopropene hauv txiv apples thiab kiwi txiv hmab txiv ntoo. |
