ag.algebraic geometry - equation for abelian varieties with a given polarization

Let A be an abelian variety of dimension g and a polarization L of type (d1,.....,dg) (let alone the case di=dj, foralli,j). What is the degree of the generators of the homogeneous ideal of A projectively embedded via the sections of L?



I know that Gross and Popescu gave results for surfaces with L of type (1,d) - for instance if d>10 the ideal is generated by quadrics - but what for other polarizations and most of all for higher dimensions? Is this known?
