Anabaena variabilis as a Promising Biofertiliser and Biochemical Enhancer of Two Local Bread Wheat Cultivars

(Rana Nassour and Seraoos Mohamad)

---

Abstract

The potential of Anabaena variabilis as a biofertiliser for two Triticum aestivum L. cultivars –Doma 6 (D6) and Bohoth 8 (B8) was tested. Three treatments were used: T1 (control, irrigated with BG11), T2 (control – N, irrigated with BG11 without NaNO3), and T3 (inoculated with A. variabilis and irrigated with BG11 without NaNO3) to evaluate their impact on pigment, carbohydrate and protein contents. Measurements were taken at 14, 21, 28 and 35 days of seedling growth (three replicates each). The results indicated that nitrogen deficiency (T2) led to a general decrease in all the studied parameters. In contrast, the presence of A. variabilis (T3) enhanced chlorophyll a, chlorophyll b, carotenoid, carbohydrate and protein contents in both studied cultivars, with significantly greater effects observed in the D6 cultivar.
