Dhirta qaarkood, sida cypress iyo geed, kuwaas oo ay adag tahay in la gooyo oo xidid la yeesho, waxay keeni karaan jarista si ay dhaqso u xididdo iyagoo ku dara qadar yar oo 2, 4-dhibcood ah indole butyric acid (IBA) iyo naphthylacetic acid (NAA).

La dhigo mid cusub goosashada ka hor, si liinta loogu sudho geedaha in muddo ah iyada oo aan la soo qaadin. Habka gaarka ah waa: ✔ In lagu buufiyo miraha liinta isku dar ah gibberellin iyo 2,4-dhibcood (5 ~ 15mg/L + 8 ~ 12mg/L) ka hor inta aan cagaarka laga dhigin huruud.

Sababtoo ah gibberellin waxay joojin kartaa hoos u dhaca chlorophyll iyo dib u dhigista jaalaha ee midhaha, iyo 2, 4-dhibcood ayaa ka hortagi kara miraha liinta ee bislaaday inay daadiyaan, isku dhafka gibberellin iyo 2, 4-dhibcood ayaa muujin kara ilaalinta miraha wanaagsan.
