Abstract
Many pistachio cultivating areas are exposed to excess magnesium amounts. In this study, the effect of excess Mg was considered via treating pistachio var. Badami with different concentrations of MgSO4 in a pot culture experiment in the soils with VA mycorrhizal fungi according to a complete randomized block design. Total length of roots and shoots, dry weights, the number of spores produced by VAM fungi, colonizations rate of the roots to VAM and the contents of Ca, Mg, K in the roots and shoots were measured. The results showed that VAM spore number, plant dry weight and root colonization rate increased as more MgSO4 was added to the pots. The contents of Ca, Mg, K in the roots were also increased. However, the Mg content of roots was higher than that of shoots

Abstract
Reduction of methoxyketon 1 by NaBH4 gives methoxyketol 2. Allthough acetate and tosylate of this alchohol were not seprated, benzoate ester was isolated. Reduction of ketol 2 by LiAlH4 gives alchohol 4. Ketol 9 does not react with methyl magnesium iodide, but methoxyketon 1 react with both methyl magnesium iodide and phenyl magnesium iodide gives corresponding hydrocarbons. Keton 13 with phenylmagnesium iodide transforms to hydrocarbon 14. Compound 12 and 14 are light sensitive, disposing to light will change each of them to a mixture.
