BUNCH WEIGHT AND FRUIT QUALITY OF "SAMANI" DATE (Phoenix dactylifera L.) AS AFFECTED BY SOME GROWTH REGULATORS.
To obtain further information about the effect of some growth regulating substances upon bunch weight and fruit quality of Samani date cultivar (12-year-old) were assessed for two successive seasons (1997 & 1998), effects of different concentrations of IAA + BA and GA3 + BA applied twice one week after pollination and two weeks later were compared on different bunches on the same palm.Both bunch and fruit fresh weight were increased by IAA + BA application especially 10 ppm IAA + 10 ppm BA treatment, followed by GA3 + BA treatments especially 5 ppm GA3 + 10 ppm BA. Whereas the percentage of seed weight was decreased with (5 ppm IAA + 10 ppm BA) treatment.The IAA + BA treatments increased fruit length and diameter especially with 10 ppm IAA + 10 ppm BA treatment, followed by GA3 + BA treatments especially 5 ppm GA3 + 10 ppm BA. Concerning L/D ratio, no significant differences were obtained between treatments with the exception in the first season where the treatment 10 ppm IAA + 10 ppm BA decreased it.TSS, reducing and total sugars were increased by IAA + BA treatments especially (10 ppm IAA + 10 ppm BA) treatments and GA3 + BA treatments especially 5 ppm GA3 + 10 ppm BA and were decreased by elevating the rate of GA3 + BA application.
The results of this experiment suggest the benefits of the application of IAA + BA to improvebunch weight and quality of Samani date fruit.
