Abstrakt: The study was conducted under plastic houses of the Department of Horticulture and Landscape Gardening at the College of Agriculture, Al-Qasim Green University, for the season (2017-2018) to study the effect of spraying with gibberellin, naphthalene, acetic acid and chelated zinc for three cultivars for Strawberry: RUBY GEM, Festival and Albion. The Randomized Complete Block Design (RCBD) was conducted with a Factorial Experiment (3×7) with three replicates and the experimental unit included one pot, for a total of 63 seedlings and the averages were compared to according to the test of less significant difference (L.S.D) under 5% probability level. The results showed that the spraying with gibberellin, Naphthalene acetic acid (NAA) and chelated zinc was significantly and gave the highest values for all studied traits. The (B2, K2, K1, B1) treatments were significantly was excelled in the rest of the treatments by giving it the highest average of this trait amounted to (22.97, 19.47, 19.45 and 18.15 leaf.plant-1), respectively. As for the trait of plant height, the treatments (B1, B2) were excelled by giving them an average amounted to (32.81, 30.80 cm), respectively. As for the trait of plant area, the treatment B2 was excelled by giving them an average amounted to 134.81 cm2. While the treatment of A2 was excelled by giving them an average of length of flower stalk amounted to 18.96 cm. The results showed that Albion cultivar (S3) was significantly excelled in traits the number of leaves, plant height and leaves area. The RUBY GEM cultivar was significantly excelled in the length of flower stalk. The results showed that Bi-interaction treatment (B2S3) was significantly excelled in traits the number of leaves, plant height and leaves area by giving them an average amounted to (24.48 leaf.pant-1, 37.12 cm, 138.12cm2), respectively.
