Plant heights and developing roots were measured. Root formation became visible around the site of wick insertion as early as 9 days after treatment began. IBA and NAA induced root formation, but IAA had no effect. With IBA more roots and less callus formed and plant elongation was less inhibited than with NAA. IBA was most effective at 5 X 10-4M when all plants formed new roots and about 17 roots were produced per plant. NAA was less effective at 5 X 10-4M than at 1 X 10-4 and 5 X 10-5M, when 7.2 and 5.6 roots, respectively, were formed/plant and 100 and 80% of the plants rooted. Control seedlings supplied with water only did not form any roots. Seedlings of the sweet almond cv. Hazanov (syn. Poria-10) were also wick-fed with 5 X 10-4M IBA and responded in a similar way to BA-88.
