Effect of Vitamin B Complex on some Biochemical Parameters of Aloe vera

Nickel and cadmium are heavy metals with some hazards for plant metabolism. The impacts of nickel chloride (۰, ۴۰۰ and ۸۰۰ μM) in the presence of vitamin B complex (۰, ۳۰ and ۶۰ ml from pharmacy commercial stock) and the impacts of cadmium chloride (۰, ۱۰۰, ۲۰۰, ۳۰۰, ۴۰۰, ۵۰۰ and ۶۰۰ μl from ۱۰۰ µM stock) in pot and cadmium nitrate (۰, ۱۰۰, ۲۰۰, ۴۰۰, ۸۰۰, ۱۶۰۰ and ۳۲۰۰ μl from ۱۰۰ µM stock) in pot on fresh weight, photosynthetic pigments including chlorophyll and carotenoid, total protein and free proline content of Aloe vera L. seedlings were investigated. The inhibitory effects of nickel and cadmium on seedling growth resulted in decrease of chlorophyll and total protein contents. Free proline increased, while the fresh weight of the seedling was not affected by the treatments. The results indicate that vitamin B complex alleviated the inhibitory effects of nickel on A. vera L. seedlings by increasing chlorophyll, fresh weight and total protein contents.
