I-Gibberellic Acid (GA3) imbewu ikhutshwe kwaye ikhule
Beka imbewu ngamanzi afudumeleyo malunga ne-30 ℃ kwaye ubathobele iiyure eziyi-10 ~ 10. Emva kokukhupha, bazihlambe ngamanzi acocekileyo, emva koko baphikise nge-10 ~ 20 PPM Gibberellic Acid (GA3) kwi-2 ~ 3 iiyure, emva koko ubambe ngamanzi acocekileyo. Kumaxesha amaqondo obushushu asezantsi, njengaseNyakatho, imbewu inokuphathwa ngobushushu owomileyo (i.e., imbewu ye-5 ℃) i-4 ~ i-4 ~) inyibilikisiwe ngamanzi acocekileyo ngaphambi kokutyala.
Kumaxesha amaqondo obushushu aphezulu, njengasezantsi, imbewu inokuphathwa ngobushushu obumanzi (i.e., kwiqondo lokushisa eliphezulu (25 ~) malunga ne-6 ~ iiyure ezili-10). Emva kokuncipha, imbewu inokupheliswa ngamanzi acocekileyo kwaye ihlwayelwe. Le ndlela inokukhuthaza ukuhluma okukhawulezayo kwembewu, ukwandisa inqanaba lokugcwalisa, kunye nexesha lokukhulisa.
Ukwenzela ukuthintela imbewu evela kubahlukumeza umonakalo wefrost kunye nosulelo olusezantsi ngexesha lokuthambisa, i-funglicides (i-fungbendaza, i-tiophandate-i-methyl, njl.njl.) Ngexesha lokuphumla. Kuba i-gibberellic acid (GA3) ingenamanzi, iGibberellin inokuchithwa kwiinyibilikisi zezinto eziphilayo (njenge-acetone, ethanol, njl. Njl.).
