Rhizogenetic Studies of Jojoba : Hormone Effect, Rooting Medium and Seasonal Variation

Vegetative propagation studies on the adventitious ischolar_maining of jojoba stem cuttings were made in response to the hormonal effects, ischolar_maining media and seasonal variations. The young sprouts of 1-2 year old branches were better than their green terminal shoot tips. Quick dip (20-30 sec) method of IBA proved to be effective. Yellowing of the underground portion of stem cutting marked the first morphological sign of ischolar_main initiation. IBA 24.6 mM with boric acid 0.5 mM as an additive was best utilized in causing rhizogenesis irrespective of the season. The ischolar_maining percentage success for stem cuttings was highcst (75%) in thc month of April but the survival of the ischolar_mained cuttings was better in February and September trials. Perlite and agropeat mixture (1:1) proved to be the most suited ischolar_maining medium for the purpose of adventitious ischolar_main formation in jojoba. However, for subsequent survival of the plantlets with well-formed ischolar_main system it is essential to transfer them to the soil and sand mixture. The ischolar_mained stem cuttings had no bearing upon the best ischolar_maining phase for their survival.
