Abstract
To obtain some information about the effect of some growth regulating substances on produced normal size seedless fruits, yield per bunch and fruit characteristics at full yellow colour stage of Samani date cultivar (12-year-old) were assessed for two successive seasons (1997 and 1998). Effects of different concentrations of IAA, GA3 and BA applied twice during the full bloom and one week later were compared on different bunches on the same palm.
                Unpollinated bunches treated with IAA and/or GA3 twice at 5,10 and 20 plus 10 ppm BA produced seedless fruits. Yet, the yield was significantly less than that of seeded fruits developed after hand pollination. Seedless IAA, GA3 and BA induced fruits were lower in average fruit weight, fruit size, seed weight, fruit length, fruit diameter and length/diameter ratio. Whereas, higher values of total soluble sugars and reducing sugars were induced compared to those produced after hand-pollination. The better effects were obtained with GA3 + BA application (20+10 ppm) and IAA + BA application (20+10 ppm).
                Results concluded that production of seedless fruits is possible and further studies should be done to produce fruits with normal size.
