Taw qhia ntxaws
Paclobutrazol yog triazole cog kev loj hlob regulator tsim nyob rau hauv 1980s.Nws yog ib qho inhibitor ntawm endogenous gibberellin synthesis.Nws kuj tseem tuaj yeem ua kom cov haujlwm ntawm indoleacetic acid oxidase thiab txo cov theem ntawm Endogenous IAA hauv cov nplej nplej.Pom tseeb tsis muaj zog ntawm kev loj hlob zoo ntawm cov noob qoob loo sab saum toj thiab txhawb kev yug me nyuam ntawm lateral buds (tillers).Cov tsos ntawm seedlings yog luv thiab muaj zog, nrog ntau tillers thiab tuab nplooj ntsuab.Lub hauv paus system yog tsim.Cov kev tshawb fawb anatomical tau pom tias Paclobutrazol tuaj yeem txo cov hlwb hauv cov hauv paus hniav, nplooj nplooj thiab nplooj ntawm cov noob nplej thiab nce cov txheej txheem ntawm tes hauv txhua lub cev.Kev tshuaj xyuas Tracer qhia tias Paclobutrazol tuaj yeem nqus tau los ntawm cov noob nplej, nplooj thiab cov hauv paus hniav.Feem ntau ntawm Paclobutrazol absorbed los ntawm nplooj tseem nyob hauv qhov nqus thiab tsis tshua thauj mus rau sab nraud.Qhov qis concentration ntawm Paclobutrazol nce cov photosynthetic efficiency ntawm yub yub nplooj;High concentration inhibited photosynthetic efficiency, nce hauv paus ua pa, txo saum toj no ua pa, txhim kho nplooj stomatal kuj thiab txo nplooj transpiration.
