Giberellic acid (ga3) noob soaking thiab germination
Muab cov noob tso rau hauv dej sov thaum txog 30 ℃ thiab soak lawv rau 6 ~ 10 teev. Tom qab coj lawv tawm, ntxuav lawv nrog dej huv, thiab tom qab ntawd soak lawv nrog 10 ~ 3 teev, thiab tom qab ntawd yaug lawv nrog dej huv. Hauv cov caij nyoog qis, xws li nyob rau sab qaum teb, cov noob tuaj yeem kho nrog cua sov kom qhuav (0 ~ 5 teev, thiab tom qab ntawd yaug nrog dej huv ua ntej sowing.
Hauv cov caij nyoog siab, xws li nyob rau sab qab teb, lub noob tuaj yeem kho nrog ntub cua sov (i.e., ntawm qhov kub (25 ~ 30 teev). Tom qab soaking, cov noob tuaj yeem muab yaug nrog dej huv thiab sown. Txoj kev no tuaj yeem txhawb nqa cov noob sai, nce germination tus nqi, thiab lub sijhawm luv luv.
Txhawm rau tiv thaiv cov noob los ntawm kev txom nyem los ntawm kev puas tsuaj los ntawm te thiab kub (xws li carbendazim, thiab lwm yam) tuaj yeem ntxiv thaum so kom huv. Txij li thaum gibileellic acid (GA3) yog insoluble hauv dej, gibberellin tuaj yeem yaj nyob rau hauv cov organic cov kuab tshuaj (xws li acetone, ethanol, thiab lwm yam) rau siv.
