Khoom Description
Abscisic acid (ABA) yog dav faib nyob rau hauv cov nroj tsuag lub nceeg vaj, ib txwm tshwm sim nyob rau hauv cov nroj tsuag xws li Sycamore, birch, sawv nplooj, cabbage, qos yaj ywm, taum mog, txiv qaub, thiab avocado. Nws inhibits noob germination, tswj bud dormancy, txhawb abscission txheej tsim thiab lub cev senescence thiab abscission, thiab yog ib qho ntawm feem ntau nthuav tawm inhibitory tshuaj nyob rau hauv cov nroj tsuag. Nws cov mis molecular yog C15H20O4, nws qhov hnyav molecular yog 264.31, nws pKa yog 4.5, nws yog sparingly soluble nyob rau hauv dej los yog benzene, tab sis yooj yim soluble nyob rau hauv methanol, acetone, ethanol, ethyl acetate, los yog alkaline aqueous daws.
Daim ntawv thov
Abscisic acid (ABA) inhibitors tuaj yeem txhawb nqa cov khoom khaws cia hauv cov noob thiab txiv hmab txiv ntoo, tshwj xeeb tshaj yog khaws cov protein thiab qab zib. Kev thov ABA sab nraud thaum lub sijhawm pib ntawm cov noob thiab kev loj hlob ntawm cov txiv hmab txiv ntoo tuaj yeem ua rau cov qoob loo ntawm cov qoob loo thiab txiv hmab txiv ntoo.
