MUHAMMAD AZHAR BASHIR1*, MUHAMMAD AKBAR ANJUM2, ZUBEDA CHAUDHRY3 AND HAMID RASHID4
Abstract: Semi-hardwood cuttings of 6 promising strains of jojoba were treated with auxins (IBA, IAA and NAA) solutions each @ 0, 1250, 2500, 5000 and 10000 mg l-1 and planted during October in sand:silt medium (1:1) under humid conditions maintained by polyethylene sheet tunnel till the end of March. Data on growth parameters regarding root, shoot and survival of the cuttings were recorded. The cuttings from PKJ-3 were the most responsive of all other strains as they took minimum time for rooting, gave maximum number of roots and leaves per cutting, length and diameter of primary root and shoot, and resulted in maximum rooting, sprouting and survival percentages. IBA significantly enhanced the root growth and increased survival of the cuttings, while IAA significantly promoted shoot growth. The highest level of each auxin was the most effective.
