Abstract
In order to study of two hormones effects of gibberellin and benzyl adenine on (Zantedeschia aethiopica cv.childsiana) pot plant characteristics, non dormant rhizomes dipped preplanting in gibberellin solution with concentrations including (0, 100, 200 and 500 ppm) and sprayed in two weeks once to flowering time with benzyl adenine solutions including (0, 100, 200 and 500 ppm). Interaction effect between these two factors was significant on number days from planting to emergencing in 1% Probability level. The max number days from planting to emergencing, occured in control treatment during 24 days, and also min of that, by application of 500 ppm gibberellin solution and 100 ppm benzyl adenine solution. Interaction effect between two hormones on chlorophyll content was significant in 5% Probability level. maximum of chlorophyll content related to application of 500 ppm gibberellin and 500 ppm benzyl adenine and min of that, was seen in control treatment. Interaction effect between was used hormones was significant on plant leaf number. Maximum leaf number was produced in application of 0 ppm gibberellin and 500 ppm benzyl adenine, also min of leaf number produced when we use 500 ppm gibberellin solution and 0 ppm benzyl adenine. The comparison of means of interaction effects between different levels on rhizome weight increasing after flowering showed that application of these hormones resulted that less increasing in rhizome weight after flowering. Respectively, with increasing of hormone concentrations, resulted decreased, rhizome weight increasing rather than control treatment.
