| Abstract | ||
| Quantitative estimation of growth regulators results Indol Acetic acid (IAA) and Gibberellic acid (GA3) using technology high performance liquid chromatography (HPLC) in strawberry plants (variety Hapil and Festival) treated with three fungi Fusarium culmorum, Cylindrocarpon spp. and Bipolaris spp.The results varied depending on the variation of ments, as the level of the growth regulators IAA and GA3 increased in fungal biocontrol Trichoderma harzianum and bacterial biocontrol Pseudomonas aerogenosa and chemocontrol Azadarachtin, compared with the non -treatment plants infected with three fungi above, the highest concentration of the growth regulator IAA was 921.81 ng/g wet weight in plants treatmed with fungal biocontrol and less concentration in the plants treated with fungus F. culmorum alone, the level was 10.20 ng/g wet weight in strawberry variety Hapil while Festival variety was the highest concentration of plant growth regulator in fungal biocontrol and less level was in the treatment with Cylindrocarpon spp. the concentrations in the rest of the transactions between the two in both varieties. The concentration of the growth regulator GA3 differed with the differentiation of the concentration of the growth regulator IAA in strawberry variety Hapil and Festival and all the transactions studied, the highest concentration of it in strawberry variety Hapil were treated bacterial biocontrol, the level was 341.97 ng / g wet weight while the level in strawberry variety Festival is 897.62 ng / g wet weight in plants treatmed with fungal biocontrol while the less level of the growth regulator GA3 in strawberry variety Hapil and Festival was 30.29 ng / g wet weight and 20.34 ng / g wet weight in the treatment with the fungus Cylindrocarpon spp. alone, the concentrations in other treatments ranged between the two in both varieties | ||
