Gibberellins (GA3) belongs rau lub ntuj cog tshuaj hormones.
1. Nws tuaj yeem txhawb nqa cov qia elongation los ntawm stimulating cell faib thiab elongation.
2. Thiab nws tuaj yeem tawg cov noob dormancy, txhawb kev loj hlob, thiab nce
txiv hmab txiv ntoo teem tus nqi, los yog ua rau parthenocarpic (seedless) txiv hmab txiv ntoo
los ntawm stimulating stems ntawm ib tsob nroj siab dua thiab nplooj loj.
3. Tom qab ntawd, nws tau raug pov thawj los ntawm kev siv ntau lawm ntau xyoo
tias kev siv gibberellins muaj txiaj ntsig zoo hauv kev loj hlob
cov nplej, nplej, pob kws, zaub, txiv hmab txiv ntoo, thiab lwm yam.
