Abstract
This research was conducted in Horticulture dept , college of agriculture and forestry , at mosul university to study the effect of three concentrations (0, 10 , & 20 ppm) of two auxins indole acetic acid (IAA) and naphthaline acetic acid (NAA) as foliar spray at two dates of application (15/3 and 15/4) on some vegetative , flowering and yield parameters of strawberry (Fragaria x ananassa Duch.) Cv. Hapil A randomized complete block design with three replicates , each experimental unit contain ten plants , Data obtained from this experiment were tested by using Duncan's multiple test at 5% level . The obtained results indicated that there was a significant effect of auxin (IAA) on some parameters (average leaf area , percentage of flower set and average yield of plant and area unit) as compared with the effect of auxin (NAA) . at the same time both concentrations (10 & 20) ppm of two auxins (IAA and NAA) caused a significant increase in all vegetative and yield parameters , and there was appositive correlation between auxin and its concentration , Meanwhile the first date of application (15/3) was more affective which caused a significant increase in percentage of flower set and average yield of plant with a non-significant increase in the rest parameters as compared with the effect of the second date of application (15/4) , The best interaction treatment was 20 ppm of auxin (IAA) spraied at the first date (15/3) which resulted in a significant increase in most vegetative , flowering , and yield parameter .
